Isoptin: instructions for use

With arterial hypertension, isoptin is prescribed. The instruction on the use of this medicine tells about the indications, side effects and contraindications.

In addition to the treatment of hypertension isoptin, the active substance of which is verapamil, it is prescribed also for angina and tachyarrhythmia. Among other ingredients of the drug are alginates and polysaccharides derived from algae (brown), which serve as a hydrocolloid matrix for the basic substance. If you take isoptin (instructions for use indicate unambiguously on this) a day once, then its therapeutic effect will be long. This drug blocks calcium channels, reduces vascular resistance, while not increasing the frequency of cardiac contractions. In addition, verapamil with constant use does not allow arrhythmias to develop and reduces in the cardiac muscle an arousal.

If the doctor has prescribed isoptin, the patient's pressure decreases within 24 hours after the start of taking the medication, and this effect will persist if the patient continues treatment according to the scheme suggested by the doctor. After all, the form of the retard allows the active substance of the drug to be released almost continuously, almost linearly, thus ensuring the maintenance of the drug level in the plasma.

If the reception is long, this period will be longer by two or three times. Isoptin is withdrawn, the instructions for use here are correct, mainly through the urinary system, and in feces it is only 16%.

Since the active substance easily overcomes the placenta, isoptin is not prescribed in pregnancy. Isoptin is also excreted with the mother's milk, but in milk its concentration is negligible, so it does not have a pharmacological effect on the baby. But experts still do not recommend taking it with lactation.

This medication is prescribed mainly in the following diseases:

• Light and medium degree of hypertension (monotherapy is prescribed);
• A severe degree of arterial hypertension (it is appointed in a complex with other medicines - diuretics, etc.).
