At a glance
Hydrochlorothiazide + Losartan Potassium combination is used for the treatment of hypertension and to reduce the risk of stroke in patients with hypertension and left ventricular hypertrophy.
Indications
- Hypertension (high blood pressure)
- Reduction of stroke risk in patients with hypertension and left ventricular hypertrophy
Pharmacology
Losartan and its active metabolite selectively block the AT1 receptor of angiotensin II, inhibiting vasoconstriction and aldosterone secretion. Hydrochlorothiazide inhibits sodium and chloride 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):
- Hypertension: Initial: 50 mg/12.5 mg once daily; may increase to 100 mg/25 mg if needed
- Severe Hypertension: Starting dose: 50/12.5 once daily; may increase to 100/25 after 2-4 weeks if needed
- Hypertension with LVH: Initial: 50/12.5; may increase to 100/12.5, then 100/25 if needed; Max: 100/25 once daily
- Volume Depletion: Start with losartan 25 mg once daily
- Elderly: Initial dose 50/12.5; Max 100/25 should not be used as initial therapy
Renal Dose: CrCl >30 mL/min: No dosage adjustment; not recommended in severe renal impairment
