Plavix - Precautions | Use | Side Effects
Plavix is a drug that contains active substance called clopidogrel. It belongs to family of antiplatelet drugs. Mechanism of action is based on inhibiting aggregation of platelets. It is used to reduce atherosclerotic events, such as:
- Heart attack
- Peripheral arterial occlusive disease
Plavix should be avoided in patients who have some genetic disorders (e.g. patients who have lack of CYP2C19 enzyme), because in such patients Plavix cannot be metabolized properly, thus leading to Plavix accumulation in the body and side effects.
