Norvasc is a medication for the basic therapy of cardiovascular diseases. The active substance of Norvasc is Amlodipine – inhibitor of slow calcium channels.
The main task of Norvasc is to restore normal blood circulation and reduce the burden on the cardiovascular system, to prevent the occurrence of complications. The pharmacological effect is achieved by blocking the transfer of calcium into the cells of smooth muscles of the heart and blood vessels.
Norvasc has a hypotensive and antianginal effect and is suitable for patients with chronic diseases of the cardiovascular system. Its pharmacological effect is developed slowly, reaching a maximum peak in 2-3 weeks after the beginning of course.
Therefore, Amlodipine is not suitable for the symptomatic treatment of hypertension, tachycardia, or other pathological disorders of the cardiovascular system.
Indications for the use of Norvasc
Norvasc is used in the basic therapy of arterial hypertension, stable vasospastic angina, myocardial ischemia, as well as in chronic heart failure.
Amlodipine is well tolerated and rarely interact with other hypotensive means, so it’s often used in combination therapy of cardiovascular diseases.
Norvasc is available in doses of 2.5 mg, 5 mg and 10 mg.
- The standard daily dose of Norvasc in treatment of hypertension is 5 mg. Some patients may have a reduced sensitivity to Amlodipine; therefore, it is allowed to increase the daily dose up to 10 mg of Norvasc.
- To prevent strokes and myocardial ischemia, it is recommended to take 1 tablet of Norvasc 10 mg 1 time per day.
- Patients with chronic heart failure must begin treatment with Norvasc 2.5 mg per day and gradually increase the dose to achieve an optimal therapeutic effect.
