Losartan, 12.5 mg, film-coated tablets, 30 pcs.

Losartan blocks the action of a natural substance in the body that causes constriction of the blood vessels of the heart, which leads to vasodilation, lowering blood pressure and reducing the load on the heart. The drug is incompatible with alcohol due to the strong effect of alcohol on the cardiovascular system.

Drinking alcohol first dilates blood vessels, thereby enhancing the effect of the drug, and then leads to their sharp narrowing (spasm). Combining Losartan tablets is dangerous due to consequences in the form of life-threatening side effects.

Compatibility of Losartan with alcohol

In the annotation for the drug, the manufacturer informs about the permissibility of combining the drug with alcohol, but only with great caution. This means that you should drink carefully and in very moderate quantities. The drug has a strong effect and is sold only by prescription. Most doctors are categorically against combining Losartan with alcohol in any quantity. This is largely due to the diseases for which the drug is prescribed.

Main indications for use:

  • Constantly high blood pressure.
  • Prevention of stroke and other cardiovascular diseases.
  • Chronic heart failure. Losartan is used as part of complex treatment.
  • Nephropathy and high blood pressure in patients with type 2 diabetes (alcohol is harmful to diabetics).

The symptoms of these diseases make drinking alcohol during treatment with Losartan extremely undesirable. Incompatibility and alcohol abuse can lead to increased side effects and serious health problems.

Hypersensitivity reactions

In patients with a history of angioedema (swelling of the face, lips, pharynx/larynx and/or tongue), monitoring of the use of the drug is necessary (see "Side effects"

).

Embryotoxicity

The use of drugs that affect the RAAS during the second and third trimester of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and mortality. The development of oligohydramnios may be associated with fetal lung hypoplasia and skeletal deformities. Possible adverse events in neonates include calvarial hypoplasia, anuria, hypotension, renal failure and death.

When diagnosing pregnancy, the drug LOSARTAN should be taken immediately.

Arterial hypotension and fluid disturbances

-
electrolyte balance or decreased circulating blood volume
In patients with reduced circulating blood volume (CBV) (for example, receiving treatment with large doses of diuretics), symptomatic arterial hypotension may occur. Correction of such conditions must be carried out before prescribing the drug LOSARTAN or starting treatment with a lower dose of the drug LOSARTAN (see " Method of administration and dosage"

»)

Fluid and electrolyte imbalance is common in patients with impaired renal function with or without diabetes mellitus, so careful monitoring of these patients is necessary. In clinical studies in patients with type 2 diabetes mellitus with proteinuria, the incidence of hyperkalemia was greater in the LOSARTAN group than in the placebo group. Several patients discontinued therapy due to hyperkalemia (see “ Side Effects”)

»).

During treatment with LOSARTAN, it is not recommended to take potassium-sparing diuretics, potassium supplements or potassium-containing salt substitutes.

Aortic or mitral stenosis, hypertrophic obstructive cardiomyopathy

Like all drugs that have a vasodilating effect, ARA II should be prescribed with caution to patients with aortic or mitral stenosis or hypertrophic obstructive cardiomyopathy.

Coronary heart disease and cerebrovascular diseases

Like all drugs that have a vasodilating effect, ARA II should be prescribed with caution to patients with coronary heart disease or cerebrovascular diseases, since an excessive decrease in blood pressure in this group of patients can lead to the development of myocardial infarction or stroke.

Chronic heart failure

As with the use of other drugs that act on the RAAS, patients with CHF and with or without impaired renal function are at risk of developing severe hypotension or acute renal impairment.

Since there is insufficient experience with the use of the drug LOSARTAN in patients with heart failure and concomitant severe renal impairment, in patients with severe heart failure (NYHA functional class IV), as well as in patients with heart failure and symptomatic life-threatening arrhythmias, the drug LOSARTAN should be prescribed with caution to patients in these groups.

Primary hyperaldosteronism

Since patients with primary hyperaldosteronism, as a rule, do not respond positively to therapy with antihypertensive drugs that act by inhibiting the RAAS, the use of LOSARTAN is not recommended in this group of patients.

Liver dysfunction

Data from pharmacokinetic studies indicate that the concentration of losartan in the blood plasma in patients with cirrhosis of the liver is significantly increased, therefore patients with a history of impaired liver function should be prescribed the drug LOSARTAN at a lower dose. There is no experience with the use of the drug LOSARTAN in patients with severe liver dysfunction, so the drug should not be used in this group of patients (see “ Pharmacological properties. Pharmacokinetics

";
" Contraindications
";
" Method of administration and dosage
").

Renal dysfunction

Due to inhibition of the RAAS, changes in renal function, including the development of renal failure, have been observed in some susceptible patients. These changes in renal function may return to normal after treatment is stopped.

Some drugs that affect the RAAS may increase blood urea and serum creatinine concentrations in patients with bilateral renal artery stenosis or renal artery stenosis of a solitary kidney. Similar effects have been reported when taking the drug LOSARTAN. Such renal dysfunction may be reversible after discontinuation of therapy. LOSARTAN should be used with caution in patients with bilateral renal artery stenosis or renal artery stenosis of a solitary kidney.

Special patient groups

Race

Analysis of data from the entire population of patients included in the LIFE study to study the effect of losartan on reducing the incidence of the main composite criterion of the study in patients with hypertension and left ventricular hypertrophy (n = 9193) showed that the ability of losartan compared with atenolol to reduce the risk of stroke and myocardial infarction, as well as reduce cardiovascular mortality in patients with hypertension and left ventricular hypertrophy (by 13.0%. p = 0.021) does not apply to patients of the Negroid race, although both treatment regimens effectively reduced blood pressure in these patients. In this study, the drug LOSARTAN, compared with atenolol, reduced cardiovascular morbidity and mortality in patients with hypertension and left ventricular hypertrophy of all races except blacks (n = 8660, p = 0.003). However, in this study, black patients receiving atenolol had a lower risk of the study's primary composite endpoint (i.e., lower combined incidence of cardiovascular death, stroke, and myocardial infarction) compared with race-matched patients receiving losartan (p= 0.03).

Children and teenagers

The effectiveness and safety of the drug LOSARTAN in children and adolescents under 18 years of age have not been established.

If oliguria or arterial hypotension develops in newborns whose mothers took LOSARTAN during pregnancy, symptomatic therapy aimed at maintaining blood pressure and renal perfusion is necessary. Blood transfusions or dialysis may be required to prevent hypotension and/or maintain renal function.

Elderly patients

Clinical studies have not revealed any particularities regarding the safety and effectiveness of losartan in elderly patients (over 65 years of age).

Double renin blockade

-
angiotensin
-
aldosterone system (RAAS)
Concomitant use of angiotensin II receptor antagonists with drugs containing aliskiren is contraindicated in patients with diabetes mellitus and/or moderate or severe renal failure (GFR less than 60 ml/min/1.73 m2 body surface area) and is not recommended in other patients.

Concomitant use of angiotensin II receptor antagonists with ACE inhibitors is contraindicated in patients with diabetic nephropathy and is not recommended in other patients.

Impact on the ability to drive vehicles and operate machinery

No studies have been conducted to evaluate the effect on the ability to drive or operate machines, but caution should be exercised when using antihypertensive therapy and driving or operating machines, as dizziness and drowsiness may develop, especially at the beginning of therapy or when the dose is increased.

Side effects and consequences

To reduce the risk of side effects, you should stop drinking alcohol during the period of treatment and carefully follow the warnings of doctors and the manufacturer (instructions for the drug).

Losartan should not be taken if there are contraindications:

  • Allergy to the components of the drug.
  • Individual intolerance to the active substance or auxiliary components.
  • Low blood pressure (blood pressure may drop too much).
  • Chronic gastritis.
  • Acute form of heart failure.
  • Children's age up to 18 children.
  • Dehydrated state of the body (including from exposure to alcohol).
  • During pregnancy and breastfeeding.

The drug has a relatively low likelihood of side effects. Symptoms are relatively mild, so symptomatic therapy or discontinuation/adjustment of the dosage of the drug is usually not required. The most dangerous symptoms occur in case of drug overdose: a sharp and severe decrease in blood pressure, bachycardia and brachycardia (decrease in heart rate to 30-40 beats per minute).

In rare cases (less than 1% of patients), the following side effects are possible:

  • Feeling of dry mouth, nausea and vomiting.
  • Functional gastrointestinal disorders (diarrhea or diarrhea).
  • Deterioration of potency, disruption of the normal functioning of the liver and kidneys.
  • Upper respiratory tract infections, bronchitis and rhenitis with symptoms corresponding to the disease.
  • Pain in the back, shoulders and lower extremities; exacerbation of arthritis.
  • Increased sweating.
  • Increased fatigue, chronic fatigue syndrome, sleep disorders.
  • Headaches and dizziness.

All these side effects, with some probability, can also occur in a person who fully complies with the recommendations of doctors and does not drink alcohol. Drinking alcohol causes a serious blow to health and increases the likelihood of negative consequences.

Consequences of combining Losartan tablets with alcohol:

  1. A sharp decrease in pressure. Alcohol dilates blood vessels, thereby causing a decrease in blood pressure for some time. If you have blood pressure-lowering drugs in your body, your blood pressure may drop too much and your heart rate may slow down dangerously.
  2. A double blow to the gastrointestinal tract and organs. The liver, kidneys and gastrointestinal tract react negatively to both alcohol and most medications. Alcohol abuse puts a strain on the kidneys and liver, increasing the likelihood of side effects and pathological processes.
  3. Symptoms of incompatibility. Symptoms can appear suddenly after drinking even a small amount of alcohol: nausea, dizziness, sudden weakness, cold extremities, loss of coordination and orientation in space.

To avoid negative consequences, do not combine alcohol with medications, spacing out taking pills and alcohol as much as possible over time. It is advisable to consult a doctor regarding the possibility of drinking alcohol for health reasons. It should be remembered that other medications taken may be incompatible with alcohol and may also change the effect of other medications.

The drug contains lactose monohydrate. It must be taken into account that the use of the drug is contraindicated in patients with rare congenital galactose intolerance, lactase deficiency or glucose-galactose malabsorption.

Features of the action of the drug at the first dose

Patients with reduced blood volume (for example, when taking high doses of diuretics, limiting salt intake, diarrhea or vomiting) may develop symptomatic hypotension, especially after taking the first dose and after increasing the dose of the drug.

Features of the action of the drug upon its withdrawal

You should not stop taking the drug without consulting a doctor, as symptoms may return.

Features of the actions of a doctor (paramedic) or patient when one or more doses of a drug are missed
