Instructions for use of PERINDOPRIL-LF (PERINDOPRIL-LF)
Dual blockade of the RAAS is associated with an increased risk of hypotension, hyperkalemia and renal dysfunction (including acute renal failure) compared with monotherapy. Dual blockade of the RAAS using ACE inhibitors, angiotensin II receptor blockers or aliskiren is not recommended, especially in patients with diabetic nephropathy.
In some cases, when the combined use of ACE inhibitors and angiotensin II receptor blockers is absolutely indicated, careful medical supervision and mandatory monitoring of renal function, water and electrolyte balance, and blood pressure are necessary. This applies to the use of candesartan or valsartan as adjunctive therapy to ACE inhibitors in patients with chronic heart failure. Carrying out double blockade of the RAAS under the careful supervision of a specialist and mandatory monitoring of renal function, water-electrolyte balance and blood pressure is possible in patients with chronic heart failure with intolerance to aldosterone antagonists (spironolactone), who have persistence of symptoms of chronic heart failure, despite other adequate therapy.
Stable ischemic heart disease
If an episode of unstable angina (severe or not) develops during the first month of treatment with perindopril, the balance between benefit and risk should be carefully assessed before continuing treatment.
Arterial hypotension
ACE inhibitors can cause a decrease in blood pressure. In patients with uncomplicated hypertension, severe hypotension rarely occurs; more often it is observed in patients with hypovolemia - while taking diuretics, limiting salt intake from food, in patients on hemodialysis, with diarrhea or vomiting; in patients with severe renin-dependent hypertension. In patients with clinically significant heart failure with or without concomitant renal failure, clinically significant arterial hypotension was recorded. The risk of its development increases in patients with more severe heart failure, while taking loop diuretics in high doses, with hyponatremia or functional kidney damage. Patients at increased risk of developing clinically significant hypotension require careful monitoring during initiation of therapy and dose adjustment. Similar requirements apply to patients with coronary artery disease or cerebrovascular disease, in whom an excessive decrease in blood pressure can lead to the development of myocardial infarction or acute cerebrovascular accident.
If arterial hypotension develops, the patient should be placed in a horizontal position and, if necessary, given intravenous saline. Transient arterial hypotension is not a contraindication to continued treatment, which can usually be restored without complications after an increase in blood pressure due to an increase in blood volume.
In some patients with congestive heart failure and normal or low blood pressure, treatment with perindopril may lead to an additional decrease in systemic blood pressure. This effect is expected and is not a reason to stop treatment. In case of clinically significant arterial hypotension, dose reduction or discontinuation of treatment with perindopril may be required.
Aortic and mitral valve stenosis/hypertrophic cardiomyopathy
As with other ACE inhibitors, perindopril should be used cautiously in patients with mitral valve stenosis and left ventricular outflow tract stenosis, in particular with aortic stenosis or hypertrophic cardiomyopathy.
Renal dysfunction
In case of impaired renal function (creatinine clearance <60 ml/min), the initial dose of perindopril should be adjusted in accordance with the clinical clearance and depending on the clinical response to treatment. Potassium and creatinine levels are usually monitored routinely in these patients.
In patients with clinically significant heart failure, the development of arterial hypotension after initiation of treatment with ACE inhibitors may lead to some deterioration in renal function. In a similar situation, acute renal failure has been described, which is usually irreversible.
In some patients with bilateral renal artery stenosis or solitary renal artery stenosis treated with ACE inhibitors, increases in serum urea and creatinine levels were detected, which were usually mild and reversible after discontinuation of treatment. This is especially likely in patients with impaired renal function. In the case of renovascular hypertension, there is an increased risk of severe hypotension and renal failure. In such patients, treatment should begin under close medical supervision with a low dose, followed by careful dose titration. Since treatment with diuretics may be a predisposing factor in the development of the above conditions, diuretics should be discontinued during the first weeks of treatment with perindopril, while monitoring renal function.
In some patients with arterial hypertension and no obvious signs of previous vascular damage to the kidneys, increases in serum urea and creatinine levels developed, which were usually mild and transient, especially when perindopril was used concomitantly with diuretics. These manifestations are more likely to develop in patients with pre-existing kidney damage. In such cases, dose reduction and/or discontinuation of diuretic and/or perindopril treatment may be necessary.
Patients on hemodialysis
In patients receiving dialysis using high-flow membranes and concomitant treatment with ACE inhibitors, the development of anaphylactic reactions has been observed. In such cases, consideration should be given to using a different type of dialysate membrane or a different class of antihypertensive drug.
Kidney transplant
There is no experience with the use of perindopril in patients with recent kidney transplantation.
Hypersensitivity/angioedema
Rarely, patients receiving treatment with ACE inhibitors, including perindopril, may develop angioedema of the face, extremities, lips, mucous membranes, tongue, vocal folds and/or larynx. This phenomenon can develop at any time during treatment. In such cases, treatment with perindopril should be stopped immediately and appropriate monitoring of the condition should be initiated until symptoms cease completely. In cases where swelling of only the face or lips was observed, it usually resolved without treatment, although antihistamines were used to relieve symptoms.
Angioedema in combination with laryngeal edema can lead to death. In case of swelling of the tongue, vocal folds and larynx with a high probability of airway obstruction, emergency treatment should be prescribed immediately. This may include administering epinephrine (adrenaline) and/or maintaining a patent airway. The patient should be under close medical supervision until symptoms disappear completely and permanently.
Patients with a history of angioedema not associated with ACE inhibitors may be at increased risk of such edema when treated with ACE inhibitors. In rare cases, life-threatening anaphylactoid reactions have developed in patients receiving ACE inhibitors during LDL apheresis with dextran sulfate. Such reactions can be avoided by temporarily suspending ACE inhibitor treatment before each apheresis procedure.
Anaphylactic reactions during desensitization
Patients receiving ACE inhibitors during desensitization (for example, to the venom of Hymenoptera - wasps, bees and other insects) developed anaphylactoid reactions. Such reactions can be avoided by temporarily withdrawing ACE inhibitors, but if accidentally reintroduced, these reactions reappear.
Liver failure
In rare cases, treatment with ACE inhibitors is accompanied by a syndrome that begins with cholestatic jaundice and progresses with the development of fulminant liver necrosis, sometimes death. The mechanism of development of this syndrome is unknown. If jaundice develops or liver enzyme levels increase significantly during treatment with ACE inhibitors, the ACE inhibitor should be discontinued and appropriate medical supervision should be provided in the future.
Neutropenia/agranulocytosis/thrombocytopenia/anemia
In patients receiving ACE inhibitors, the development of neutropenia/agranulocytosis, thrombocytopenia and anemia is observed. In patients with normal renal function and without other complicating factors, neutropenia rarely develops. Perindopril should be used very cautiously in patients with collagen diseases, immunosuppressant therapy, treatment with allopurinol or procainamide, or a combination of these complicating factors, especially in the case of pre-existing renal impairment. Some of these groups of patients develop serious infections, which in many cases do not respond to active antibiotic therapy. When prescribing perindopril to such patients, periodic monitoring of leukocyte levels is recommended. Patients should be informed to report any signs of infection to their physician.
Race
ACE inhibitors are more likely to cause angioedema in blacks compared to patients of other races.
Similar to other ACE inhibitors, perindopril is less effective in lowering blood pressure in blacks compared to patients of other races; a possible explanation is the widespread prevalence of arterial hypertension with low renin levels among representatives of the black race.
Cough
When treated with ACE inhibitors, a cough may develop. Characterized by a non-productive persistent cough, which stops after discontinuation of treatment. Cough caused by an ACE inhibitor should be considered in the differential diagnosis of cough.
Surgery/anesthesia
During major surgery or during anesthesia with drugs that cause hypotension, perindopril may block the formation of angiotensin II due to compensatory release of renin. Treatment should be stopped the day before surgery. If arterial hypotension associated with this mechanism develops, it can be corrected with fluid therapy.
Hyperkalemia
Increases in potassium levels have been observed in some patients during treatment with ACE inhibitors, including perindopril. Patients at risk of developing hyperkalemia include those with renal failure, uncontrolled diabetes mellitus, those taking potassium-sparing diuretics, potassium supplements or salt substitutes containing potassium, and other drugs that increase potassium levels (eg, heparin). If concomitant use of these drugs is necessary, regular monitoring of potassium levels is recommended.
Patients with diabetes mellitus
In patients with diabetes mellitus taking oral hypoglycemic agents or insulin, glycemic levels should be carefully monitored during the first month of treatment with an ACE inhibitor.
Lithium preparations
The combination of lithium and perindopril is generally not recommended.
Potassium-sparing diuretics, potassium supplements and potassium-containing salt substitutes
In general, combinations of perindopril and potassium-sparing diuretics, potassium supplements and potassium-containing salt substitutes are not recommended.
Excipients
The drug contains lactose, so it should not be prescribed to patients with rare hereditary diseases:
- congenital galactosemia, lactase deficiency, glucose/galactose malabsorption syndrome.
Use in pediatrics
It is not recommended to prescribe the drug to children and adolescents under the age of 18 years,
because There are no data on the effectiveness and safety of perindopril tertbutylamine in this category of patients.
Impact on the ability to drive vehicles and operate machinery
No studies have been conducted on the effect on the ability to drive and operate machines.
If it is necessary to drive vehicles or operate machinery while using the drug, the possibility of dizziness or fatigue should be taken into account.
Compatibility of Perindopril and alcohol
? Perindopril is a medicine prescribed to patients with serious heart and vascular diseases. To alleviate their condition, patients should lead a measured lifestyle, excluding overload and bad habits. Drinking alcoholic beverages can not only make the treatment pointless, but also provoke a vascular accident.
The annotation for the medication states: it is recommended to exclude alcohol during the course of treatment. Combining medications with alcohol-containing drinks can have serious consequences.
Taking alcohol together with medication can cause:
- exacerbation of ischemia:
- hypertensive crisis;
- a sharp drop in blood pressure;
- cardiac conduction disorders, arrhythmias;
- deterioration of the function of the excretory system.
The likelihood of complications depends on the condition and age of the sick person, the amount and strength of the alcohol-containing drink.
Consequences of drinking alcohol
The systematic combination of medication with strong drinks often causes a serious deterioration in the patient’s condition:
- The drug causes lethargy, drowsiness, and disorientation. During intoxication, the likelihood of falling and getting injured increases.
- An increase in heart rate is accompanied by a decrease in the density of cardiac muscle fibers. There is a malfunction of the sinus node.
- The medicine is often prescribed to patients during rehabilitation after a heart attack or stroke. Drinking strong drinks during this difficult period can cause a second attack.
- When ethanol enters the bloodstream, the blood vessels dilate, and when interacting with the drug, this leads to a drop in blood pressure. After some time, a sharp narrowing of the capillaries occurs - the pressure rises critically. Jumps in blood supply can lead to rupture of the walls of blood vessels.
- Taking the drug simultaneously with alcohol is especially dangerous for older people, whose capillaries are less elastic.
Combination with ethanol reduces the therapeutic effect of the drug and increases general intoxication of the body.
Use of the drug for alcoholism
Significant difficulties during treatment arise if the patient has an alcohol addiction. Patients with chronic alcoholism do not realize the severity of the consequences and may take a large dose of alcohol.
Such patients are prone to breakdowns and serious violations of a sober lifestyle. Often alcoholics cannot adequately assess their condition.
Relatives of a person are obliged to notify the attending physician about the existing problem. The specialist weighs the advisability of using the medication, taking into account the patient’s painful craving for alcohol.

When can I take the drug? How long after?
The simultaneous use of medicine and alcohol is unacceptable. If alcohol is present in the body, you need to maintain a time interval for removing ethanol.
After how many hours you can take the medicine depends on the type and amount of alcohol taken and the severity of the disease. Beer and wine are eliminated from the body within 2-4 hours, the effect of drinks with a strength of 30-40 degrees lasts up to 10-14 hours.
Taking the medicine while intoxicated or during a hangover is contraindicated under any circumstances.
Using the drug for a hangover
The effect of the product is designed for 24 hours. In case of renal pathologies, the period of drug elimination is prolonged. The combination of a hangover syndrome with a medicine located in the body tissues against the background of a serious illness can lead to unpredictable consequences.
A hangover is a potentially life-threatening condition:
- blood thickening caused by dehydration leads to the formation of blood clots;
- narrowing of blood vessels can cause arterial stenosis;
- severe intoxication creates additional stress on the heart;
- Nausea, vertigo, and headache are typical.
Taking the drug during a hangover can provoke a severe attack of angina, increase tachycardia and arrhythmia.
