With cardiac pathologies, doctors prescribe the drug "Erinit." The instruction recommends taking this remedy for ischemia. The medicine is somewhat reminiscent of the principle of action of Nitroglycerin. However, the effect of taking "Erinit" occurs much later, approximately 30-40 minutes after use. This tool can not be used as an "ambulance" to stop an attack of angina pectoris. But the medicine at the same time has a long-lasting effect. It is intended to prevent heart pain associated with ischemia.
The composition and effect of the drug
The active component of the drug is pentaerythritol tetranitrate. This substance dilates the venous vessels and reduces the manifestations of ischemia. As a result, the load on the heart and myocardial oxygen demand are reduced.
The drug is slowly absorbed, so its effect does not occur immediately, but only after about half an hour after administration. It lasts about 8-10 hours. Therefore, such a medicine can not be used to relieve pain in the heart, but can be used to prevent an attack.
The medicine is released in the form of tablets. They contain 10 or 20 mg of the active ingredient. They also include auxiliary ingredients: talc, starch, glucose, sucrose, stearic acid salts.

How to take pills

If the patient suffers from night pain in the heart, then to prevent them take 20 mg of medicine at bedtime. This will protect against an attack throughout the night.

Different opinions are found in patients. Some patients report that this drug helped them prevent heart pain. Against the background of taking the medicine, angina attacks began to occur much less often.
However, not all patients consider this drug to be quite effective. The effect of taking the medicine occurs only after a long time. Many patients complain of headache and dizziness after taking the pill.
