Amlodipine-Prana – drug class antihypertensive and antianginal means. If the doctor prescribed you the medication before taking it is familiar with its operation, as well as features.
The main component of the drug Amlodipine-Prana is amlodipine. Amlodipine was originally marketed by Pfizer as a drug called Norvasc. Currently, many companies in Russia, Eastern Europe and India produce their own medicines containing amlodipine. In addition, amlodipine is included in the list of essential medicines of the who.
Chemists refer to amlodipine, dihydropyridine derivatives, and pharmacologists – a selective blocker of slow calcium channels. The drug is representative of the 2nd generation of this type of funds.
Advantages of drugs of the 2nd generation compared to 1st generation tools, are:
- the increased duration of action,
- the high level of tissue specificity,
- fewer side effects.
Most effective amlodipine in ischemic heart disease, with which he has anti-sclerotic and cardioprotective action.
How else could the amlodipine implements these functions? The compound blocks the flow of calcium ions into certain cells, primarily in muscle cells covering the blood vessel walls. The lack of calcium in these cells causes an expansion of the lumen of blood vessels. Basically the drug acts on the muscle cells responsible for contraction of blood vessels, not in heart muscle cells. However, the drug has not only vasodilator, but also anti-anginal effect, that is, it reduces the need heart of oxygen. This effect occurs due to the expansion of arterioles and large coronary arteries. Vazodilatiruushimi effect of the drug also leads to a decrease in blood pressure.
For drug is not is characterized by the occurrence of reflex tachycardia type. In patients with stable angina drug that promotes physical activity easier for them migrate. It is important that angina the drug reduces the frequency of attacks. The drug does not reduce left ventricular ejection of the heart and thus helps reducing the degree of left ventricular hypertrophy. Amlodipine does not affect the conductivity of the cardiac muscle, metabolic processes in the body, metabolism of fats and glucose in the blood. It can be used by diabetic patients suffering from bronchial asthma and gout. In addition, the drug has a slight diuretic effect.
Most often the drug is administered to people who have problems with the cardiovascular system. First and foremost is coronary heart disease in the stage of compensation, of Prinzmetal angina (spastic angina), exertional angina, stable angina.
The second main category of people who have shown the drug, that people suffering from arterial hypertension. Typically, receiving funds, reducing blood pressure, is recommended in stable pressures exceeding 140/90. However, in some cases, medication may be prescribed and people with lower pressure.
Hypotensive effect begins to manifest itself after 2-4 hours after administration and a significant reduction in blood pressure occurs in about 6-10 hours and lasts about a day. The stationary concentration of active substance in the blood observed after 7-8 days after the start of. Thus, the drug is not very effective hypertensive crises. This tool is not for emergency care, but rather for long-term symptomatic treatment of hypertension.
It should be noted that, despite the fact that the drug has some contraindications, to take remedy for hypertension or ischemia should not be. Only the specialist can choose the most effective drug in each case.

Older people dose adjustment is not required, but they need more careful observation of the doctor.
Do not require dose modification in patients receiving thiazide diuretics, ACE inhibitors and drugs that block beta-adrenergic receptors.

Interactions with other substances and drugs
A nonsteroidal anti-inflammatory drugs, especially indomethacin, alpha-agonists, anaesthetics, sympathomimetics, estrogens, calcium preparations, can reduce the effectiveness of amlodipine. Concomitant use of these drugs may cause the development of hypertensive crises.
This effect occurs because of fluid retention in the body. On the other hand, diuretics, nitrates, antihypertensives (other medicines belonging to the group of calcium channel blockers, ACE inhibitors and beta-blockers), drugs that have antianginal effects (riboxinum, nitroglycerin), quinidine, increase its hypotensive and antianginal efficacy.
Alpha blockers and antipsychotics only increase anti-hypertensive effect means.
Amlodipine may increase the neurotoxicity of lithium products. Neurotoxic effects can include ringing in the ears, trembling of extremities, loss of coordination, nausea and vomiting.
The product is compatible with cardiac glycosides. A single alcohol ingestion does not affect therapeutic effect of the drug. However, we are talking about single dose. Long-term use of alcohol may counteract the effect of the drug. Does not affect the action of the drug a single dose of sildenafil (Viagra).
