At a glance
Hydrochlorothiazide + Olmesartan Medoxomil combination is used for the treatment of hypertension.
Indications
- Hypertension (high blood pressure)
Pharmacology
Olmesartan selectively blocks the AT1 receptor of angiotensin II, inhibiting vasoconstriction and aldosterone secretion. Olmesartan does not inhibit ACE and is not metabolized by the cytochrome P450 system. Hydrochlorothiazide inhibits Na+/Cl- reabsorption in the distal convoluted tubule, increasing sodium and chloride excretion, which reduces plasma volume and activates the renin-aldosterone system.
Dosage
Adult Dose (Oral):
- Initial: 20 mg/12.5 mg once daily
- May increase to 40 mg/25 mg after 2 weeks if needed
- Hepatic Impairment: No dosage adjustment necessary
