Plavix is a trading name of the active ingredient Clopidogrel. The medicine has a specific action that stops an aggregation of platelets and thins the blood.
The active ingredients of Plavix do not have a therapeutic activity. The action happens only when Clopidogrel turns into the active metabolites. One of its active metabolites has a pharmacological activity and is able to stop the aggregation of the platelets.
Changes in the blood happen in the first day after the use of a onetime therapeutic dose. On 4-5th days, a therapeutic day achieves its maximum and synthesis of platelets is reduced by 50-60%.
The pharmacological action of Plavix is reversible. It means that a reduction of the aggregation of platelets happens only during the use of the tablets. If you stop taking the medicine, all processes will be restored in a week, and a duration of the bleeding will be normal.
Plavix is able to prevent an acute platelet developing due to atherosclerosis, during any site of atherosclerotic vascular changes (including atherosclerosis of the brain, heart, peripheral arteries).
Plavix is the most important ingredient of the drug therapy of the ischemic heart disease, coronary syndrome and ciliary arrhythmia. It helps to reduce complications after myocardial infarction and ischemic stroke.
According to the results of the studies, Plavix has a good tolerance, does not provide a side effect on the cardiovascular system and does not cause a medical addiction.
