Mechanism of action of the drug?
Perindopril belongs to a group of drugs called angiotensin-converting enzyme (ACE) inhibitors, which work by relaxing blood vessels so blood can flow more easily. Perindopril will act through the action of the perindoprilat metabolite, which converts angiotensin I to angiotensin II which is a potent vasoconstrictor and promotes the growth of vascular smooth muscle cells and myocardium, and causes the breakdown of bradykinin, which is a potent vasoconstrictor. vasodilation.
In hypertensive patients, perindopril will reduce blood pressure by reducing systemic peripheral resistance, thereby increasing peripheral blood flow without affecting heart rate. The drug can dilate both arteries and veins. The patient's blood pressure can return to normal within 1 month and remains stable without exceeding the therapeutic effect of long-term treatment. Reflux did not occur upon discontinuation of treatment and the effect was maintained for 24 hours after a single dose.
