A high blood pressure exhausts the cardiovascular system. If the treatment of hypertension is not started in time, serious complications such as disorder of the cerebral blood circulation and renal failure may appear. Due to Norvasc, you will control the rates of the blood pressure and prevent the development of complications in time.
Norvasc is a medicine for the treatment of the high blood pressure. It contains an active ingredient Amlodipine. This medicine has been approved by FDA and is widely used in the cardiological practice as a hypotensive product.
A hypotensive effect of Norvasc may be noticed in the first day of taking the pills. The drug dilates the peripheral blood vessels and reduces afterload to the heart and the walls of the blood vessels. Norvasc dilates the blood vessels and ischemic zones of myocardium, and this will result in the supply of more oxygen to the myocardium and a prevention of the spasms.
Norvasc does not cause a prompt reduction of the blood pressure. It acts softly, and a pill controls the rates of the blood pressure within 24 hours. The action of Norvasc begins after the use of the first pill but the maximal hypotensive effect occurs in 3-5 days after the accumulation of the active ingredients in the body.
Indications for the use
- Treatment of hypertension in patients older than 18 years
- Prevention and treatment of angina pectoris (angina of effort and vasospastic angina)
- Prevention of coronary heart disease
In what dose is Norvasc used?
To treat hypertension, patients are recommended to begin the treatment with a minimal dose of Norvasc 2,5 mg per day. The pills are taken every day, at the same time, with a glass of water. If a hypotensive effect is weak in 5-7 days, and you feel a stable high blood pressure, the dose of Norvasc is increased up to 5 mg per day. Norvasc 5 mg is used not more than once per day (in 24 hours). If cardiac angina, patients are prescribed Norvasc 5 mg per day at once.
Senior patients and patients with renal failure do not lower the daily dose. However, it is necessary to consider a fact that these patients have longer period of half-life of the active ingredients, and this may be reflected in the laboratory tests of the blood and urine.
In case of the overdose with Norvasc, a hypotensive action is increased and a load to the cardiovascular system is created. The overdose symptoms are intense reduction of the blood pressure with possible development of reflex tachycardia, convulsions, and loss of consciousness.
A stomach lavage and a symptomatic therapy of the side effects is prescribed for the overdose.
- Norvasc may be safely used with diuretics, alpha and beta-adrenoceptors, and other antianginal products (including nitrates)
- Using Norvasc with other hypotensive products, it is necessary to take into account a mutual reinforcement of the therapeutic action. That is why, a daily dose of both drugs may be lowered in some cases
- If you recently had myocardial infarction, the use of Norvasc is contraindicated
- Patients with chronic heart failure, renal failure are not prescribed Norvasc. A decision about the use of the medicine during these diagnosis is made by a cardiologist
- Patients under 18 years old are contraindicated to take Norvasc.
