Trimetazidine MB-Teva, 35 mg 60 pcs

Pharmacotherapeutic group: antihypoxant

ATX code: C01EB15

Pharmacological properties

Pharmacodynamics

Trimetazidine prevents intracellular decrease in adenosine triphosphatase (ATP) activity under conditions of ischemia and hypoxia, preserving energy metabolism and ensuring cell homeostasis by ensuring normal functioning of cell membrane ion channels and transmembrane sodium-potassium flow. It inhibits beta-oxidation of fatty acids by selectively blocking the enzyme 3-ketoacyl-CoA-thiolase, which enhances glucose oxidation. Cells in ischemia require less oxygen for energy in the process of glucose oxidation than in the process of beta-oxidation of fatty acids.

The switch of cellular energy metabolism from fatty acid oxidation to glucose oxidation underlies the pharmacological effects of trimetazidine. Under experimental conditions it has been shown that the drug:

• maintains the energy metabolism of the heart and neurosensory tissues under ischemia;
• reduces the severity of intracellular acidosis and changes in transmembrane ion flux occurring during ischemia;
reduces migration and infiltration of polynuclear neutrophils in ischemic and reperfused heart tissues;
• reduces the size of myocardial damage;
• does not adversely affect hemodynamic parameters.

In patients with ischemic heart disease, trimetazidine acts as a metabolic agent, maintaining sufficient intracellular high-energy phosphate activity in the myocardium. The anti-ischemic effect is achieved without affecting hemodynamics.

In patients with stenocardia trimetazidine:

• increases coronary reserve, thereby delaying the onset of exercise-induced ischemia beginning on day 15 of therapy;
• limits exercise-induced blood pressure fluctuations without significant changes in heart rate;
• reduces the frequency of angina attacks and the need for short-acting nitroglycerin;
• improves left ventricular contractile function in patients with coronary dysfunction.

Pharmacokinetics

When taken orally, trimetazidine is rapidly absorbed from the gastrointestinal (GI) tract, with maximum plasma concentration reached in an average of 5 hours. For more than 24 hours, the plasma concentration of trimetazidine is maintained at levels greater than or equal to 75% of maximum.

The equilibrium state of the drug concentration in blood is reached after 60 hours. Food intake has no effect on the pharmacokinetic properties of trimetazidine. The volume of distribution is 4.8 l/kg. The binding to plasma proteins is low and in vitro is 16%.

Trimetazidine is mainly excreted by the kidneys, mainly unchanged. When administered orally at a dose of 35 mg, the half-life in young healthy volunteers is on average 7 hours; in patients over 65 years of age, it is 12 hours.

The total renal clearance of trimetazidine directly correlates with creatinine clearance (CK), hepatic clearance decreases with age.

Patients over 75 years

In patients over 75 years of age, increased plasma exposure to trimetazidine may be observed as a result of age-related decline in renal function. No differences have been found regarding the safety of the drug in patients over 75 years of age compared to the general population.

Patients with impaired renal function

. Plasma exposure to trimetazidine was increased approximately 2.4-fold in patients with moderate renal dysfunction (CK 30-60 mL/min), and approximately 4-fold in patients with severe renal dysfunction (CK less than 30 mL/min) compared with healthy volunteers with normal renal function.

There were no findings regarding the safety of the drug in patients with impaired renal function compared to the general population.

Application in children and adolescents

The pharmacokinetics of trimetazidine in children and adolescents less than 18 years have not been studied.

Indications

Active ingredient

Composition

How to take, the dosage

Overly, with meals.

1 tablet (35 mg) 2 times a day (morning and evening). Tablets should be taken whole, without chewing, with water.

The duration of treatment is decided by the doctor. The result of the treatment is evaluated after three months. If the treatment is not effective, Trimetazidine MB-Teva should be discontinued.

Patients with renal impairment

In patients with moderate renal impairment (CK 30-60 ml/min), the recommended dose is 35 mg (1 tablet) in the morning with breakfast.

Elderly patients over 75 years

Elderly patients may have increased exposure to trimetazidine due to age-related decreased renal function. In patients with moderate renal impairment (CKD 30-60 ml/min), the recommended dose is 35 mg (1 tablet) in the morning with breakfast.

Caution should be exercised when adjusting the dose in elderly patients.

Interaction

Special Instructions

If one or more doses of Trimetazidine MV-Teva are missed, the higher dose should not be taken at the next dose.

Trimetazidine MB-Teva is not intended to control angina attacks, nor is it indicated as an initial treatment for unstable angina or myocardial infarction. It should not be taken before hospitalization or in the first few days of hospitalization.

In case of an attack of angina, coronary pathology should be reassessed and the treatment used should be adjusted (drug treatment and possibly revascularization).

The drug Trimetazidine MB-Teva may cause or worsen the symptoms of parkinsonism (tremor, akinesia, increased muscle tone). Patients should be monitored regularly, especially in the elderly. In doubtful cases, the patient should be referred to a neurologist for appropriate examination.

The development of movement disorders, such as parkinsonian symptoms, restless legs, tremor, wobbly walking, may lead to withdrawal of trimetazidine.

The incidence of movement disorders is low, reversible, and resolves after discontinuation of the drug. If symptoms of parkinsonism persist more than 4 months after discontinuation of the drug, a neurologist should be consulted.

If unsteady walking or low muscle tone, especially when using antihypertensive therapy, the patient may fall (see side effects).

Trimetazidine should be administered with caution in patients who may have increased exposure to it:

Influence on driving and operating ability

Because of the possible development of dizziness and other side effects, caution should be exercised when driving vehicles and engaging in other activities requiring increased concentration and rapid psychomotor reactions.

Synopsis

Contraindications

Cautions

Patients with severe hepatic impairment, moderate renal impairment, and elderly patients over 75 years of age (increased exposure to trimetazidine may occur).

Side effects

The following criteria are used to assess the incidence of side effects: very common (≥1/10); common (≥1/100, < 1/10); infrequent (≥1/1000, < 1/100); rare (≥1/10000, < 1/1000); very rare (< 1/10000), frequency unknown – based on available data it is not possible to estimate the frequency.
