Nitresan® [Nitrendipine]

Nitresan tablets^®"Used to treat essential hypertension.

Structure

The active substance is nitrendipine (one tablet contains 10 mg of nitrendipine).

Excipients: lactose monohydrate, corn starch, microcrystalline cellulose, magnesium stearate, povidone, sodium docusate.

Contraindications

• hypersensitivity to nitrendipine or to another 1,4-dihydropyridine calcium antagonist or to any auxiliary component of the drug;
• cardiogenic shock;
• severe stenosis of the aortic valve;
• unstable angina pectoris;
• acute myocardial infarction, which occurred during the previous 4 weeks;
• concomitant use with rifampicin.

Mode of application

Assign inside in the morning after eating. The tablets should be swallowed whole without chewing, washed down with a sufficient amount of water (for example, a glass). It is strictly forbidden to drink grapefruit juice.

The active substance nitrendipine is sensitive to light, so tablets should be removed from the blister just before use.

One tablet of Nitresan^®"Take twice a day (morning and evening), which is 20 mg of nitrendipine per day. With an insufficient decrease in blood pressure, the doctor during treatment can double the daily dose and take 2 tablets twice a day, which is equivalent to a daily dose of 40 mg.

The maximum daily dose is 40 mg.

The dose and number of doses are set by the doctor individually. To achieve the maximum therapeutic effect, individual dosage of the drug is recommended depending on the condition of the patient, his reaction to the drug and tolerance. The duration of treatment is determined by the clinical condition of the patient.

Elderly patients and patients with impaired liver function

Nitrendipine metabolism can slow down, leading to an undesirable decrease in blood pressure. Since the therapeutic effect can be enhanced and / or prolonged, it is recommended to start treatment with low doses (10 mg nitrendipine per day) under the supervision of a doctor.

In cases of a significant decrease in blood pressure, even with low doses, it is necessary to change the treatment.

Impaired renal function

Patients with impaired renal function of mild to moderate severity do not require special dose adjustments.

Application features

Pregnant women

The drug is contraindicated during pregnancy.

Nitrendipine passes into breast milk. If necessary, the use of the drug should stop breast-feeding.

Children

The drug is not used for children due to the lack of data on the effect of its effects and safe use.

Drivers

At the beginning of treatment or when using high doses, or in combination therapy with other antihypertensive drugs, or while drinking alcohol, it is recommended to refrain from driving vehicles and from potentially dangerous activities that require increased attention and speed of psychomotor reactions, since with a decrease in blood pressure it can decrease the level of attention.

Overdose

Symptoms of acute intoxication

Hot flashes, headache, arterial hypotension (circulatory collapse), change in heart rate (tachycardia or bradycardia).

Treatment

It is necessary to remove the drug from the body: rinse the gastrointestinal tract, take activated charcoal. Conduct careful monitoring of the state of vital functions of the patient. With a significant decrease in blood pressure, dopamine and norepinephrine should be taken. Attention should be paid to the possible negative effects of catecholamines (especially in relation to cardiac arrhythmias). With bradycardia, intravenous administration of atropine or orciprenaline (similar to the treatment of intoxication with other calcium channel blockers).It is possible to re-introduce 10 ml of 10% calcium gluconate or 10% calcium chloride, followed by calcium infusion (it is necessary to prevent the possible development of hypercalcemia). In such cases, catecholamines are also effective, but at higher doses. Further treatment is symptomatic.

Nitrendipine is not amenable to dialysis, therefore hemoperfusion and plasmapheresis will not be effective.
