HYDROCHLOROTHIAZIDE INTENSOL vs INDERIDE-40/25
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits sodium-chloride symporter in distal convoluted tubule, reducing sodium and chloride reabsorption and increasing water excretion.
Inderide-40/25 is a combination of propranolol (non-cardioselective beta-blocker) and hydrochlorothiazide (thiazide diuretic). Propranolol reduces heart rate, myocardial contractility, and renin secretion via beta-adrenergic receptor blockade. Hydrochlorothiazide inhibits Na+/Cl- cotransporter in distal convoluted tubule, increasing excretion of Na+, Cl-, and water; also reduces peripheral vascular resistance.
25-100 mg orally once daily or in divided doses. Titrate based on response; maximum 200 mg/day.
One tablet (40 mg propranolol HCl/25 mg hydrochlorothiazide) orally twice daily; may increase to maximum of 160 mg propranolol/100 mg hydrochlorothiazide per day in divided doses.

Terminal half-life 6–15 hours (mean ~10 hours); prolonged in renal impairment (creatinine clearance <30 mL/min) and elderly.
Propranolol: 3-6 hours (terminal); clinical context: dosing 2-3 times daily due to short half-life; may accumulate in hepatic impairment. Hydrochlorothiazide: 6-15 hours (terminal); clinical context: longer in renal impairment.
Primarily renal (≥95% as unchanged drug); negligible biliary/fecal elimination (<5%).
Propranolol: extensively metabolized in liver via CYP2D6 and glucuronidation; <1% excreted unchanged in urine. Hydrochlorothiazide: ~70% excreted unchanged in urine via tubular secretion.
