Pharmacodynamics and pharmacokinetics
Pharmacodynamics
A combination drug containing a calcium channel blocker ( amlodipine ) and a β1-adrenergic receptor ( bisoprolol ).
Amlodipine has a hypotensive and antianginal effect. It blocks the flow of calcium into the myocardial cells and vascular muscles. The hypotensive effect is due to the relaxing effect on the vascular muscles. The antianginal effect is realized by dilating peripheral arterioles and coronary arteries. Dilatation increases oxygen access to the myocardium. In case of hypertension, a decrease in blood pressure throughout the day. The onset of action of amlodipine is slow, so there is no sharp decrease in blood pressure.
For angina pectoris , it reduces the frequency of attacks, lengthens the time of physical activity, and reduces the need for nitrates. Does not affect changes in lipid levels, can be used for concomitant diabetes mellitus , asthma and gout .
Bisoprolol also has a hypotensive and antianginal effect. By blocking adrenergic receptors , it reduces the myocardial for oxygen and eliminates the severity of ischemia . The hypotensive effect is achieved after 2 weeks of administration.
Pharmacokinetics
When taken orally, amlodipine Cmax is determined after 6–12 hours . Bioavailability 65–80%. About 95–98% is protein bound. Metabolized in the liver. T½ from the blood - 35–50 hours. Administered mainly by the kidneys.
Bisoprolol is almost completely absorbed from the gastrointestinal tract . Bioavailability - about 90%. The half-life is 10–12 hours. Protein binding is 30%. Half the dose of bisoprolol is metabolized in the liver and excreted as metabolites by the kidneys. The remaining half unchanged is also excreted by the kidneys.

Pharmacotherapeutic group Selective beta-blockers in combination with other antihypertensive drugs. ATC code C07FB Pharmacological properties Pharmacokinetics After oral administration, amlodipine is well absorbed and peak blood levels are reached 6-12 hours after administration. Food intake does not affect its bioavailability. Absolute bioavailability is 64-80%. Volume of distribution 21 l/kg. Equilibrium plasma concentration (5-15 ng/ml) is achieved after 7-8 days of daily dosing. In vitro studies have shown that 93-98% of amlodipine circulating in the bloodstream is bound to plasma proteins. Amlodipine is rapidly metabolized (approximately 90%) by the liver to inactive pyridine derivatives. 10% of the parent compound and 60% of inactive metabolites are excreted in the urine, 20-25% in the feces. The decrease in plasma concentration is biphasic. The terminal elimination half-life from blood plasma is approximately 35-50 hours, and corresponds to once daily dosing. The total clearance is 7 ml/min/kg (for a patient weighing 60 kg - 25 l/hour). In elderly patients, this value is 19 l/hour. The pharmacokinetics of amlodipine does not undergo significant changes in renal failure and with increasing age of patients. In case of liver failure - due to decreased clearance - a reduction in the initial dose is recommended. Bisoprolol is almost completely (> 90%) absorbed from the gastrointestinal tract. Due to the very low first-pass effect through the liver (approximately 10%), the absolute bioavailability of the drug after oral administration is about 90%. The volume of distribution is 3.5 l/kg. Bisoprolol binding to plasma proteins is 30%. Bisoprolol is excreted from the body in two ways: 50% is metabolized by the liver to inactive metabolites, which are then excreted by the kidneys. The remaining 50% is excreted unchanged by the kidneys. Since elimination occurs equally in the kidneys and liver, no dosage adjustment is required in patients with mild to moderate hepatic or renal impairment. The total clearance is approximately 15 l/h. The elimination half-life from plasma is about 10 hours. The kinetics of bisoprolol is linear and does not depend on age. Pharmacodynamics Alotendin is a combined antihypertensive drug that contains a slow calcium channel blocker (amlodipine) and a selective beta-blocker (bisoprolol). The drug has an antihypertensive effect. Amlodipine inhibits the transmembrane transition of calcium ions into myocardial and smooth muscle vascular cells (slow calcium channel blocker or calcium ion antagonist). The mechanism of antihypertensive action is associated with a direct relaxing effect on vascular smooth muscle, which leads to a decrease in peripheral vascular resistance. The exact mechanism by which angina symptoms are relieved is not fully established, but may involve: 1) dilatation of peripheral arterioles, thereby reducing total peripheral resistance (afterload). Since this does not lead to reflex tachycardia, myocardial energy expenditure and oxygen demand are reduced. 2) due to the expansion of the main coronary arteries and arterioles, both in normal and ischemic areas, oxygen supply is improved. Due to this, the supply of oxygen to the myocardium increases, even in the case of spasm of the coronary arteries (variant angina or Prinsmetal angina). In patients with arterial hypertension, a single dose of the drug throughout the day provides a clinically significant decrease in blood pressure, both in the supine and standing positions. Due to the slow onset of action, sudden arterial hypotension is not common. In patients with angina pectoris, with a single dose per day, the total time of tolerance to physical activity, the time until the development of an angina attack and the time until significant depression of the ST segment increases, and the frequency of angina attacks and the number of glyceryl trinitrate tablets consumed decreases. This was not associated with adverse metabolic effects: the drug had no effect on plasma lipids, blood sugar or serum uric acid levels, and was beneficial in patients with asthma. Bisoprolol is a potent, highly selective β1-adrenergic blocker, lacking intrinsic sympathomimetic activity (ISA), and it does not have significant membrane-stabilizing properties. It has low affinity for β2 receptors of bronchial and vascular smooth muscle, as well as β2 receptors related to metabolic regulation. For this reason, it is unlikely that bisoprolol has an overall effect on airway resistance and β2-mediated metabolic effects. β1 selectivity extends beyond the therapeutic dosage range. Bisoprolol does not have a clear negative inotropic effect. The maximum effect of bisoprolol develops 3-4 hours after its oral administration. The elimination half-life from plasma (10-12 hours) provides 24-hour effectiveness after once daily dosing of the drug. Typically, the maximum antihypertensive effect develops after 2 weeks. When administered acutely to patients with coronary heart disease without chronic heart failure, bisoprolol reduces heart rate and stroke volume and, thus, cardiac output and oxygen consumption. With prolonged administration, the initially increased peripheral resistance decreases. The antihypertensive effect of β-blockers is, among other things, associated with a decrease in renin activity. Bisoprolol inhibits the response to sympathoadrenergic activation by blocking β-receptors in the heart. This leads to a decrease in heart rate and suppression of myocardial contractility, which leads to a decrease in the oxygen demand of the heart muscle. Indications for use - arterial hypertension in the form of monotherapy or, if necessary, as part of combination therapy with other antihypertensive drugs - chronic stable angina in the form of monotherapy or, if necessary, as part of combination therapy with other antianginal drugs - as replacement therapy in patients blood pressure and/or chronic stable angina pectoris in which can be adequately controlled by the simultaneous use of amlodipine and bisoprolol in the same doses. Method of administration and doses The drug is used strictly as prescribed by the doctor! Alotendine is indicated for patients in whom high blood pressure or coronary vascular pathology can be adequately controlled by separate administration of monocomponent drugs in the same doses as in the recommended fixed combinations. The recommended daily dose is 1 tablet of a certain dosage. Alotendine is recommended to be taken in the morning, regardless of meals, without chewing. Treatment should not be stopped suddenly, as this may lead to a temporary deterioration of the clinical condition. Especially treatment should not be abruptly stopped in patients suffering from coronary heart disease. A gradual dose reduction is recommended. In case of liver failure, elimination of amlodipine may be delayed. There are no precise dosing recommendations for amlodipine, so the drug should be prescribed with caution in these patients. In case of severe liver failure, the daily dose of bisoprolol should not exceed 10 mg. In patients with mild to moderate renal impairment, no dosage change is required. In case of severe renal failure (creatinine clearance less than 20 ml/min), the daily dose of bisoprolol should not exceed 10 mg. Elderly patients can be prescribed the usual doses of the drug. Side effects Often (³1/100 - <1/10) - palpitations, bradycardia - headache, dizziness, drowsiness, fatigue - nausea, vomiting, diarrhea, constipation, abdominal pain - "hot flashes" - swelling, peripheral edema - feeling of coldness and numbness of the extremities Uncommon (³1/1,000 - <1/100) - leukopenia, thrombocytopenia, purpura - visual disturbances, sleep disorders, depression - peripheral neuropathy, syncope, hypoesthesia, paresthesia, taste perversion, tremor - arterial hypotension, AV disorders conductivity, worsening of existing heart failure - shortness of breath, cough, rhinitis, bronchial asthma or bronchospasm with a history of obstructive pulmonary disease - pollakiuria, urination disorder, nocturia - arthralgia, myalgia, muscle cramps, back pain, muscle weakness, cramps - dryness in the mouth, gingival hyperplasia, dyspepsia, pancreatitis - increased sweating, alopecia, skin discoloration - hyperglycemia - vasculitis - exhaustion, asthenia, increase or decrease in body weight - impaired potency, gynecomastia - mood changes Rarely (³1/10,000 - <1/1,000 ) - allergic skin reactions, itching, rash, angioedema, exudative erythema multiforme - hypersensitivity reactions such as itching, hot flashes, rash - arterial hypotension - decreased secretion of tear fluid (this should be taken into account if the patient wears contact lenses) - hearing impairment, nightmares, hallucinations - increased triglyceride levels - allergic rhinitis - increased levels of liver enzymes (ALAT, AST), hepatitis - impaired potency Very rare (<1/10,000), unknown (cannot be assessed based on available data) - urticaria - gastritis - increased levels of liver enzymes - cholestasis, jaundice, hepatitis* Very rare (<1/10,000), - conjunctivitis - alopecia - β-blockers can provoke or worsen the course of psoriasis, or can cause psoriasis-like changes on the skin Mental disorders As well as In the case of other calcium antagonists, undesirable effects have been reported (myocardial infarction, arrhythmia (for example, ventricular tachycardia and atrial fibrillation) and angina), on the basis of which it is impossible to decide whether they are related to the underlying disease or not. * These symptoms are especially typical at the beginning of treatment. In general, they are mildly expressed and most often disappear within 1-2 weeks. Contraindications - hypersensitivity to amlodipine, dihydropyridine derivatives, bisoprolol and/or any of the excipients - unstable angina - severe aortic stenosis - acute heart failure or episodes of heart failure requiring intravenous drugs with inotropic action - cardiogenic shock - AV block II or III degree (without pacemaker) - sick sinus syndrome - sinoatrial block - bradycardia (heart rate less than 60 beats/min) before treatment - arterial hypotension (systolic blood pressure < 100 mmHg) - severe bronchial asthma or severe chronic obstructive pulmonary disease - late stages of occlusive peripheral arterial disease and severe Raynaud's syndrome - untreated pheochromocytoma - metabolic acidosis - breastfeeding Drug interactions Drug interactions are not yet fully known. Caution must be exercised when using the drug together with thiazide diuretics, β-blockers, long-acting nitrates, sublingual glyceryl trinitrate preparations, non-steroidal anti-inflammatory drugs, antibiotics, and oral hypoglycemic drugs. Co-administration of Alotendin with digoxin did not lead to changes in serum digoxin levels and did not affect the renal clearance of digoxin. Co-administration of the drug with cimetidine did not affect the pharmacokinetics of amlodipine. Amlodipine does not affect the binding of digoxin, phenytoin, coumarin and indomethacin to plasma proteins. Co-administration of Alotendin and warfarin did not cause a significant effect on prothrombin time. Drinking grapefruit juice may result in a slight increase in serum amlodipine levels but does not produce clinically significant changes in blood pressure. Not recommended combinations: - calcium antagonists such as verapamil and, to a lesser extent, such as diltiazem, have a negative effect on contractility, atrioventricular conduction and blood pressure. Intravenous administration of verapamil in patients receiving treatment with beta-blockers can lead to severe hypotension and atrioventricular block; - simultaneous use with centrally acting antihypertensive drugs (for example, clonidine, methyldopa, moxonodine, rilmenidine) can lead to a decrease in heart rate, cardiac output and vasodilation. Abrupt discontinuation of the drug may result in an increased risk of “withdrawal syndrome in the form of hypertension.” Combinations of Alotendine with the following drugs should be used with extreme caution: - calcium antagonists of the dihydropyridine type, such as nifedipine, may increase the risk of arterial hypotension, and in patients with heart failure the risk of increased further deterioration of ventricular pumping function cannot be excluded; - class I antiarrhythmic drugs (for example, disopyramide, quinidine, lidocaine, phenytoin, flecainide, propafenone) may potentiate the effect on atrioventricular conduction time and may enhance the negative inotropic effect; - class III antiarrhythmic drugs (for example, amiodarone) can potentiate the effect on atrioventricular conduction time; - parasympathomimetic drugs can cause an increase in atrioventricular conduction time and, thus, increase the risk of developing bradycardia; - topical preparations containing a beta-blocker (for example, eye drops for the treatment of glaucoma) may alter the systemic effects of the drug; - Insulin and oral antidiabetic drugs may increase the hypoglycemic effect. β-adrenergic receptor blockade may mask symptoms of hypoglycemia; — digitalis glycosides can cause a decrease in heart rate and an increase in atrioventricular conduction time; - non-steroidal anti-inflammatory drugs (NSAIDs) can reduce the hypotensive effect of the drug; - β-sympathomimetic drugs (for example, isoprenaline, dobutamine) can reduce the effect of both drugs; - antihypertensive drugs, as well as other drugs that have a hypotensive effect (for example, tricyclic antidepressants, barbiturates, phenothiazines) may increase the risk of arterial hypotension. In patients undergoing general anesthesia, β-blockade reduced the incidence of arrhythmia and myocardial ischemia during induction of anesthesia and intubation, as well as in the postoperative period. It is currently recommended that β-blockade be maintained perioperatively. The anesthesiologist should be aware of β-blockade due to the potential for interaction with other drugs, which can cause bradyarrhythmia, weakening of reflex tachycardia and inhibition of the reflex ability to compensate for blood loss. If it is necessary to discontinue a beta blocker prior to surgery, this should be done gradually and completed within approximately 48 hours prior to anesthesia. Combinations of alotentin with drugs requiring consideration: - Meplokin can increase the risk of bradycardia; -Monoaminoxidase inhibitors (with the exception of Mao-B inhibitors): they can enhance the hypotensive effect of β-blockers, as well as increase the risk of hypertensive crisis. Special instructions in patients with heart failure of the II/III class according to NYHA Alothentin did not cause deterioration in the clinical state with respect to the tolerance of physical exertion, changes in the fraction of the release of the left ventricle and clinical symptoms. In patients with heart failure of the III/IV class, Nyha, using ACE inhibitors, diuretics and digoxin, the addition of alotentin to the treatment regimen did not cause an increase in the frequency of cardiovascular pathology or cardiovascular mortality. Since vasodilation, induced by the technique of alotentin, is characterized by a gradual beginning, cases of acutely developing arterial hypotension were rarely reported. Especially in the case of coronary heart disease, treatment should not be stopped suddenly, unless there are clear indications for the cancellation of the drug, since this can lead to a temporary deterioration in cardiac pathology. Alotentin should be prescribed with particular caution to patients with arterial hypertension or angina pectoris associated with heart failure. The drug should be used with caution in the following conditions: - diabetes mellitus with large fluctuations in blood glucose levels, symptoms of hypoglycemia can be disguised; - strict starvation/diet; -at the same time, the desensitizing therapy (as in the case of taking other β-blockers, the drug can cause an increase in sensitivity to allergens and weighting anaphylactic reactions. The use of adrenaline cannot always give the expected therapeutic effect); -AB-block of I degree; - angina pectoris Princes; - occlusal diseases of the peripheral arteries (increased complaints can be especially pronounced at the beginning of treatment); -psoriasis or its presence in a history-in this case, only β-blockers (bisoprolol) should be used after a thorough consideration of benefits and risks; - in the treatment of alotentin, symptoms of hyperthyroidism can be erased; -patients with pheochromocytoma of alotentin should be prescribed only after the blockade of α-receptors; -Before the general anesthesia, the anesthetist should receive information about the patient’s admission of β-blockers. If it is necessary to cancel the β-blocker before surgical intervention, this should be completed gradually and completed about 48 hours before anesthesia; - with bronchial asthma and other chronic obstructive lung diseases that can cause symptoms, bronze -based therapy should be carried out at the same time. In some cases, patients with bronchial asthma may develop an increase in the resistance in the respiratory tract, and for this reason an increase in the dose of β2-stimulators may require. The use of Alotentin in pediatrics is not recommended for children and adolescents under the age of 18 due to the lack of security and efficiency of use in this category of patients. Pregnancy and breastfeeding in toxicological tests in the effect of amlodipine on reproductive function, any effect on fertility or general reproductive ability was not noted. Like other β-blockers, maternal toxicity and embryonic/ neonatal toxicity were shown in relation to bisoprolol, but no teratogenic effect was observed. Due to the lack of sufficient clinical experience in the use of the drug during pregnancy and lactation, in case of pregnancy or in the case of a question of therapy in women with childbearing potential, not applying effective methods of contraception, amlodipine can only be prescribed for very strict indications after a thorough consideration of the correlation Risk/benefit. In the absence of other alternatives, in the case of alotentin therapy, lactation is recommended. Bisoprolol has pharmacological effects that can cause a harmful effect on pregnancy and/or fetus/newborn. In general, β-blockers reduce placental perfusion, which causes growth retardation, intrauterine death, spontaneous abortion and early birth. In the fetus and a newborn, undesirable effects (hypoglycemia and bradycardia) can be observed. If treatment with β-blockers is necessary, selective β1-blockers are preferred. Alotentin should not be used during pregnancy, unless there are strict indications for that. If treatment with alotentin is considered necessary, careful monitoring of uterine-placental blood flow and fetal growth is required. In case of negative impact on pregnancy or fetus, the issue of alternative treatment should be solved. Newborns should be carefully observed. Symptoms of hypoglycemia and bradycardia are generally expected during the first 3 days. There is no data on the excretion of the drug into breast milk, so the appointment of alotentin when breastfeeding is not recommended. Features of the effect of the drug on the ability to drive a vehicle or potentially dangerous mechanisms. Based on clinical experience, we can assume the lack of influence on these abilities. Nevertheless, given the variability of individual reactions to the drug, the ability to drive vehicles and mechanisms can be violated. Such an effect is most often noted at the beginning of treatment, with a change in treatment and in case of simultaneous use of alcohol. Overdose symptoms: bradycardia, arterial hypotension, bronchospasm, acute heart failure and hypoglycemia. There is wide interpersonal variability in sensitivity and in reaction to a single high dose of bisoprolol: patients with heart pathology are more sensitive to the effects of bisoprolol. With a massive overdose, excess peripheral vasodilation with severe and persistent arterial hypotension and, possibly, reflex tachycardia, is possible. There are data on very rare cases of deliberate overdose. Treatment: with an overdose, the drug should be canceled, and supportive and symptomatic treatment has begun. Taking into account the slow absorption of the drug, gastric lavage. In the case of clinically significant arterial hypotension, active cardiovascular support, monitoring of the heart and breathing, lifting the lower extremities, control over the volume of circulating fluid and diuresis, as well as intense supporting therapy are necessary. The use of vasoconstrictors may be useful in restoring vascular tone and blood pressure, provided that there are no contraindications to their use. Intravenous administration of gluconate calcium can contribute to the regression of the effects of blockade of calcium channels. With bradycardia: intravenous administration of atropine. If the answer is insufficient, isoprenaline or other drugs with a positive chronotropic effect can be prescribed with caution. In some cases, a transvenous installation of an artificial rhythm driver may be required. With arterial hypotension: intravenous infusions and vasopressors; Intravenous introduction of a glucagon. With AB-blockade (II or III degree): carefully monitoring the patient's condition, infusion of isoprenaline or may require implantation of an artificial rhythm driver. With a sudden deterioration of heart failure: intravenous administration of diuretics, drugs with a positive inotropic effect, vasodilators. In bronchospasm: the use of bronchodilators (for example, isoprenaline, β2-sympatomymetics and/or aminophylline). With hypoglycemia: intravenous administration of glucose. Since the drug has a high degree of binding with blood plasma proteins, dialysis will not give tangible benefits.

OVERDOSE
For amlodipine.
Due to slow absorption, gastric lavage is an effective procedure. Overdose (taking large doses) of amlodipine can lead to excessive peripheral vasodilation and prolonged arterial hypotension and possibly reflex tachycardia. For clinically significant hypotension, it is necessary to provide active cardiovascular support, monitor cardiac and respiratory activity, elevate the lower extremities, monitor circulating fluid volume and diuresis, and provide intensive supportive care. It is recommended to use vasoconstrictors to restore vascular tone and blood pressure, unless there are contraindications to their use. Intravenous administration of calcium gluconate promotes regression of calcium channel blockade. Amlodipine is not eliminated by hemodialysis.
For bisoprolol.
The most common symptoms of overdose are bradycardia, arterial hypotension, acute heart failure, bronchospasm, hypoglycemia. In case of overdose, supportive and symptomatic treatment is indicated. Bradycardia is treated with intravenous atropine. If this is not enough, isoprenaline or another drug with a positive chronotropic effect may be prescribed with caution. In some circumstances, a transvenous pacemaker may be required.
Arterial hypotension: intravenous infusions, vasopressors. Administration of glucagon may also be helpful.
AV block (second or third degree): Patients should be closely monitored, isoprenaline should be administered, or a pacemaker may be required.
Acute heart failure: IV diuretics, drugs with a positive monotropic effect, and vasodilators should be used.
Bronchospasm: use bronchodilators such as isoprenaline,
β2-sympathomimetics and/or aminophylline.
Hypoglycemia: intravenous administration of glucose solution.
Limited data indicate that bisoprolol is almost not eliminated by hemodialysis.
USE DURING PREGNANCY OR BREAST-FEEDING
For amlodipine.
Due to the lack of sufficient clinical experience regarding the use of the drug during pregnancy and lactation, amlodipine can be prescribed only for strict indications, provided that the benefit to the mother outweighs the possible risk to the fetus or in women of reproductive age who do not use effective contraception during treatment.
Lactation. In the absence of alternative therapy, it is recommended to stop breastfeeding.
For bisoprolol. Beta-blockers reduce placental perfusion, which causes growth retardation, fetal death, spontaneous abortion, and premature birth. Hypoglycemia and bradycardia may occur in the fetus and newborn. If treatment with beta-blockers is necessary, selective beta-blockers predominate.
Bisoprolol should not be used during pregnancy unless there are clear indications for this. If treatment with bisoprolol is determined to be necessary, monitoring of the uteroplacental circulation and fetal growth should be carried out. In case of negative effects on pregnancy or fetus, alternative treatment should be considered. Newborns should be closely monitored. Hypoglycemia and bradycardia can usually be expected in the first 3 days.
Lactation.
It is not known whether the drug is excreted into breast milk, and if it is, whether bisoprolol could harm the baby. In this regard, the use of amlodipine/bisoprolol tablets during breastfeeding is not recommended.
CHILDREN
Alotendine is not recommended for use in children.
APPLICATION FEATURES
For amlodipine.
Patients with impaired liver function. As with other calcium antagonists, the half-life of amlodipine is prolonged in patients with impaired liver function. Therefore, amlodipine should be administered to such patients with caution, with careful monitoring of liver enzyme levels.
Amlodipine should be prescribed with caution in patients with heart failure.
For elderly patients, the recommended dosage is the same as for other patients, but dose increases should be done with caution.
For bisoprolol.
Especially for patients suffering from coronary heart disease, sudden cessation of treatment with bisoprolol, if there are no clear indications, can lead to an exacerbation of the disease. Bisoprolol should be administered with caution to patients with hypertension or angina associated with heart failure.
Bisoprolol should be used with caution in the following conditions:
- diabetes mellitus with significant fluctuations in blood glucose levels; symptoms of hypoglycemia may be masked;
strict fasting or dieting;
This drug contains an active substance that gives positive results when
anti-doping control.
ABILITY TO INFLUENCE REACTION SPEED WHEN DRIVING VEHICLES OR WORKING WITH OTHER MECHANISMS
Given the different individual patient reactions to the use of the drug, the ability to influence the reaction rate when driving vehicles or operating other mechanisms may be impaired, especially at the beginning of treatment, when treatment is changed, or in the case of concomitant alcohol use.
Alotendin, instructions for use (Method and dosage)
The tablets are taken in the morning without chewing. The daily dose is one tablet of the appropriate dosage. Treatment is started with the minimum dose - Alotendin 5/5 mg, which is gradually increased if necessary. The dosage range makes it possible to select the dose depending on the clinical picture and the prevalence of certain symptoms.
The maximum daily dose is Alotendin 10/10 mg once a day.
In case of severe liver and kidney failure, the dose of bisoprolol should not exceed 10 mg; Alotendin 5/10 mg tablets may be used.
Treatment should not be stopped suddenly, as this may worsen the condition (angina pain appears).

Pharmacological properties
Pharmacodynamics.
Amlodipine is a slow calcium channel blocker that blocks the transmembrane flow of calcium ions into myocardial and vascular smooth muscle cells. The mechanism of the antihypertensive effect of amlodipine is due to a direct relaxing effect on vascular smooth muscle. The antianginal effect of amlodipine is due to two mechanisms:
- expansion of peripheral arterioles and, as a result, a decrease in peripheral vascular resistance (afterload). Since heart rate does not change, reducing the load on the heart reduces myocardial energy consumption and its oxygen demand;
- expansion of the main coronary arteries and arterioles in both unchanged and ischemic areas of the myocardium. This dilation increases the supply of oxygen to the myocardium in patients with vasospastic angina (Prinzmetal's angina or variant angina).
In patients with hypertension, taking amlodipine once a day provides a clinically significant decrease in blood pressure over 24 hours. Due to the slow onset of action of amlodipine, a sharp decrease in blood pressure is not observed.
In patients with angina pectoris, amlodipine prolongs the total time of physical activity, the time until the onset of an angina attack and the time until the onset of significant ST segment depression, and also reduces the frequency of angina attacks and reduces the need for nitroglycerin.
Amlodipine does not cause undesirable metabolic effects or changes in plasma lipid levels, so it can be used in patients with asthma, diabetes mellitus and gout.
Bisoprolol is a selective β1-adrenergic receptor blocker, without BCA, and also without pronounced membrane-stabilizing properties.
Blocks β1-adrenergic receptors and reduces the effect of catecholamines on them. Has antihypertensive and antianginal effects.
The mechanism of antihypertensive action is carried out by reducing cardiac output, sympathetic stimulation of peripheral vessels and the release of renin by the kidneys.
The antianginal effect is associated with blockade of β1-adrenergic receptors, which leads to a decrease in myocardial oxygen demand through negative chronotropic and inotropic effects. Thus, bisoprolol eliminates or reduces the severity of ischemic symptoms.
The maximum effect occurs 3–4 hours after oral administration. Typically, the maximum hypotensive effect is achieved after 2 weeks of use.
Pharmacokinetics.
Amlodipine
After oral administration in therapeutic doses, amlodipine is well absorbed and reaches Cmax in the blood 6–12 hours after administration. Food intake does not affect the bioavailability of amlodipine. Absolute bioavailability is 64–80%. The volume of distribution is about 21 l/kg. In vitro studies revealed that about 93–98% of circulating amlodipine is bound to plasma proteins.
Amlodipine is metabolized in the liver to form inactive metabolites, 10% of the drug is excreted unchanged in the urine and 60% in the form of metabolites, 20–25% in feces.
T½ from blood plasma is about 35–50 hours, which allows you to take the drug once a day.
Bisoprolol is almost completely (up to 90%) absorbed from the gastrointestinal tract. The effect of the first passage through the liver is insignificant (about 10%), absolute bioavailability is about 90%. T½ from blood plasma is 10–12 hours, which provides a therapeutic effect for 24 hours after a single daily dose.
Volume of distribution - 3.5 l/kg. Binding to blood plasma proteins is 30%.
Bisoprolol is excreted from the body in two ways. 50% is metabolized in the liver to inactive metabolites, which are excreted by the kidneys. The remaining 50% is excreted unchanged by the kidneys. Active metabolites are not formed in the human body.
Indications
Hypertension, as monotherapy or in combination with other antihypertensive drugs.
Stable angina, as monotherapy or in combination with other antianginal drugs.
As replacement therapy in patients whose blood pressure and/or stable angina are adequately controlled by the simultaneous use of amlodipine and bisoprolol in the same doses.
Application
The recommended daily dose is 1 tablet of the appropriate dosage, which should preferably be taken in the morning, regardless of meals, without chewing.
The maximum daily dose is 1 tablet of Alotendin 10 mg/10 mg/day.
The dosage range of the drug allows you to flexibly select the ratio of components depending on the clinical need.
Treatment should not be stopped suddenly as this may lead to a temporary deterioration of the clinical condition. This is especially true for patients with coronary artery disease. A gradual dose reduction is recommended.
Liver and kidney dysfunction
In case of liver failure, the elimination of amlodipine slows down. There are no specific recommendations regarding the dosage of amlodipine, so the drug should be prescribed with caution in patients with impaired liver function. In case of severe liver failure, the daily dose of bisoprolol should not exceed 10 mg.
There is no need to change the dosage in patients with mild or moderate renal impairment. In case of severe renal failure (creatinine clearance <20 ml/min), the daily dose of bisoprolol should not exceed 10 mg.
Elderly patients can be prescribed the usual doses of the drug.
The combination drug amlodipine/bisoprolol is not recommended for use in children under 18 years of age due to the lack of data regarding the safety and effectiveness of the drug.
Contraindications
Amlodipine: unstable angina, severe aortic stenosis.
Bisoprolol: acute heart failure, cardiogenic shock, AV block II-III degree, sick sinus syndrome, sinoatrial block, bradycardia (heart rate <60 beats/min) before treatment, arterial hypotension (systolic blood pressure <100 mm Hg .), asthma, COPD, severe peripheral circulatory disorders, Raynaud's syndrome, untreated pheochromocytoma, metabolic acidosis.

special instructions
Amlodipine
Patients with impaired liver function. As with other calcium antagonists, the half-life of amlodipine is prolonged in patients with impaired liver function. Therefore, amlodipine should be prescribed to such patients with caution and careful monitoring of liver enzyme levels.
Amlodipine should be prescribed with caution in patients with heart failure.
For elderly patients, there is no need to change the dosage, but dose increases should be done with caution.
Bisoprolol
Especially in patients with coronary artery disease, sudden cessation of bisoprolol treatment, if there are no clear indications, can lead to an exacerbation of the disease. Bisoprolol should be administered with caution to patients with hypertension or angina associated with heart failure.
Bisoprolol should be used with caution in the following conditions:
- diabetes mellitus with significant fluctuations in blood glucose levels; symptoms of hypoglycemia may be masked;
- strict fasting or dieting;
- concomitant desensitizing therapy. Bisoprolol may increase sensitivity to allergens and the severity of anaphylactoid reactions;
- AV block of the first degree;
- Prinzmetal's angina;
- peripheral vascular occlusive disease;
- in patients with psoriasis or with a history of psoriasis, use only after a thorough assessment of the benefit/risk ratio;
- when treated with bisoprolol, the symptoms of thyrotoxicosis may be masked;
- in patients with pheochromocytoma, bisoprolol can be used only after therapy with α-adrenergic receptor blockers;
- Before performing general anesthesia, the doctor must be informed about the patient's use of β-adrenergic receptor blockers. If it is necessary to discontinue the use of bisoprolol before surgery, this must be done 48 hours before anesthesia;
- for asthma and other chronic obstructive respiratory diseases, β-adrenergic receptor blockers are used in minimal doses in combination with bronchodilators. Sometimes, in patients with asthma, airway resistance may increase, which may require increasing the dose of β2-agonists.
The drug contains an active substance that leads to a positive result during anti-doping control.
During pregnancy and breastfeeding
Amlodipine
Due to insufficient clinical experience regarding the use of the drug during pregnancy and lactation, amlodipine can be prescribed only according to strict indications, provided that the benefit to the mother outweighs the possible risk to the fetus; also in women of reproductive age who do not use effective contraception during treatment.
In the absence of alternative therapy, it is recommended to stop breastfeeding.
Bisoprolol
β-adrenergic receptor blockers reduce placental perfusion, which can lead to growth retardation, fetal death, spontaneous abortion, and premature birth. The fetus/newborn may experience hypoglycemia and bradycardia. If treatment with β-adrenergic blockers is necessary, the use of selective β1-adrenergic blockers is preferable.
Bisoprolol should not be used during pregnancy unless there are clear indications for this. If treatment with bisoprolol is necessary, placental circulation and fetal development should be monitored. In case of a negative effect on the course of pregnancy or the fetus, it is necessary to decide on alternative treatment. Newborns should be closely monitored. Hypoglycemia and bradycardia can usually develop in the first 3 days.
It is not known whether the drug passes into breast milk and whether bisoprolol is harmful to the baby. In this regard, the use of amlodipine/bisoprolol tablets during breastfeeding is not recommended.
Children
Alotendine is not recommended for use in children.
The ability to influence reaction speed when driving vehicles and working with other mechanisms. Given the varying individual patient responses, the ability to influence reaction time when driving or operating machinery may be impaired, especially at the beginning of treatment, when treatment is changed, or in the case of simultaneous use of alcohol.
Interactions
Amlodipine
Drugs whose simultaneous use requires caution: thiazide diuretics, beta-adrenergic blockers, long-acting nitrates, sublingual nitroglycerin, NSAIDs, antibiotics and oral hypoglycemic drugs.
The simultaneous use of amlodipine with digoxin does not lead to a change in the concentration of digoxin in the blood plasma and does not affect its renal clearance.
Concomitant use of amlodipine with cimetidine does not affect the pharmacokinetics of amlodipine.
Concomitant use of amlodipine with warfarin does not significantly affect prothrombin time.
Drinking grapefruit juice may lead to a slight increase in plasma concentrations of amlodipine, but this does not lead to clinically significant changes in blood pressure.
Bisoprolol
Concomitant use with:
calcium antagonists (verapamil and, to a lesser extent, diltiazem): negatively affect contractility, atrioventricular conduction and blood pressure. IV administration of verapamil in patients using beta-adrenergic blockers can lead to severe arterial hypotension and AV blockade;
centrally acting antihypertensive drugs (clonidine, methyldopa, moxonodine, rilmenidine): simultaneous administration of these drugs can lead to a decrease in heart rate, cardiac output and vasodilation. Sudden discontinuation of the drug may increase the risk of developing withdrawal syndrome in the form of hypertension.
Drugs whose simultaneous use requires caution:
- calcium antagonists of the dihydropyridine type, such as nifedipine: due to an increased risk of arterial hypotension and heart failure;
- class I antiarrhythmic drugs (for example, disopyramide, quinidine, lidocaine, phenytoin, flecainide, propafenone): due to an increased negative effect on myocardial inotropic function, AV conduction;
- class III antiarrhythmic drugs (eg amiodarone): due to an increased effect on atrioventricular conduction;
- parasympathomimetics: when used concomitantly, atrioventricular conduction time may increase and therefore increase the risk of bradycardia;
- local agents containing beta-adrenergic blockers (eye drops for the treatment of glaucoma) can complement the systemic action of bisoprolol;
- insulin and oral antidiabetic agents: increased hypoglycemic effect. β-adrenergic receptor blockade may mask signs of hypoglycemia;
- cardiac glycosides: decrease in heart rate, prolongation of AV conduction;
- NSAIDs: decreased antihypertensive effect;
- β-sympathomimetics (isoprenaline, dobutamine): combination with bisoprolol can reduce the severity of the effects of both drugs;
- tricyclic antidepressants, barbiturates, phenothiazines, and other antihypertensive drugs: increase the risk of developing arterial hypotension.
Inhalation anesthetics, hydrocarbon derivatives (chloroform, cyclopropane, halothane, methoxyflurane, etc.): when used simultaneously with beta-adrenergic receptor blockers, the risk of inhibition of myocardial function and the development of hypotensive reactions increases. The effect of non-depolarizing blockers of neuromuscular transmission can be enhanced and prolonged by the influence of beta-adrenergic receptor blockers.
Drugs whose simultaneous use requires discussion:
- mefloquine: increased risk of bradycardia;
- MAO inhibitors (except for MAO-B inhibitors): enhancing the hypotensive effect of beta-adrenergic receptor blockers, as well as increasing the risk of a hypertensive crisis.
Overdose
Amlodipine
Due to slow absorption, gastric lavage is an effective procedure. Overdose (high dose intake) of amlodipine can lead to excessive peripheral vasodilation and prolonged arterial hypotension and possibly reflex tachycardia. In case of clinically significant arterial hypotension, it is necessary to actively maintain the function of the cardiovascular system, monitor cardiac and respiratory activity, elevate the lower limbs, monitor blood volume and diuresis, and conduct intensive supportive therapy. It is recommended to use vasoconstrictors to normalize vascular tone and blood pressure, unless there are contraindications to their use. IV administration of calcium gluconate helps neutralize the blockade of calcium channels. Amlodipine is not eliminated by hemodialysis.
Bisoprolol
The most common symptoms of overdose are bradycardia, arterial hypotension, acute heart failure, bronchospasm, hypoglycemia. In case of overdose, supportive and symptomatic treatment is indicated. Bradycardia is treated with intravenous atropine. If this is not sufficient, isoprenaline or another drug with a positive chronotropic effect can be administered with caution. In some circumstances it may be necessary to install a pacemaker.
Arterial hypotension: intravenous infusions, vasopressors. Administration of glucagon may also be helpful.
AV block (2nd or 3rd degree): Patients should be under close medical supervision, isoprenaline should be administered, or a pacemaker may need to be installed.
Acute heart failure: IV diuretics, drugs with a positive chronotropic effect, and vasodilators should be used.
Bronchospasm: use bronchodilators such as isoprenaline, β2-sympathomimetics and/or aminophylline.
Hypoglycemia: intravenous administration of glucose solution.
There is limited evidence that bisoprolol is almost not eliminated by hemodialysis.
Reviews about Alotendin
There are few reviews about the drug, since it is rarely found in the pharmacy chain. All of them are positive and there is little information about side effects. Patients note that the drug was prescribed for a combination of hypertension, angina pectoris and severe tachycardia , with preserved sinus rhythm, resistant to other drugs. This drug was prescribed at first in small doses, and after 2 weeks, under the supervision of a doctor, the dose was increased. This is especially true for the dose of bisoprolol - it was increased to 10 mg over several weeks.
- “... I take Alotendin tablets for high blood pressure. These pills suit me and don’t cause any side effects, my tachycardia has calmed down.”
- “... When I took amlodipine alone, my blood pressure decreased at a high dose, but swelling appeared in my legs. This drug can reduce blood pressure with a lower dose and without swelling.”
- “... I found my drug - it keeps my blood pressure normal, calms my heart and doesn’t bother me with heart pain.”
