Olmesartan Doc Generici (Olmesartan Medoxomil)

Olmesartan medoxil is an antihypertensive agent that acts on the renin‑angiotensin system to lower blood pressure.

• Essential hypertension: reduces systolic and diastolic pressure to target levels.
• Diastolic hypertension: provides better control of diastolic readings.
• Hypertension with cardiovascular risk: helps lower risk of stroke and myocardial infarction.

• Olmesartan medoxil selectively blocks the binding of angiotensin II to the AT1 receptors on vascular smooth‑muscle and adrenal cells. This inhibition prevents vasoconstriction and aldosterone secretion, leading to vasodilation, reduced peripheral resistance and a decrease in blood pressure.

Adverse reactions reported with olmesartan medoxil vary in frequency and severity.
