HYDROCHLOROTHIAZIDE INTENSOL vs INDERIDE LA 80/50
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.
Combination of propranolol (non-selective beta-blocker) and hydrochlorothiazide (thiazide diuretic). Propranolol blocks beta-1 and beta-2 adrenergic receptors, reducing heart rate, myocardial contractility, and blood pressure. Hydrochlorothiazide inhibits sodium-chloride symporter in distal convoluted tubule, increasing excretion of sodium, chloride, and water, reducing plasma volume.
25-100 mg orally once daily or in divided doses. Titrate based on response; maximum 200 mg/day.
One capsule orally once daily, containing propranolol hydrochloride 80 mg (immediate release) and hydrochlorothiazide 50 mg. May be titrated based on response, with maximum propranolol dose 640 mg/day and maximum hydrochlorothiazide dose 50 mg/day.

Terminal half-life 6–15 hours (mean ~10 hours); prolonged in renal impairment (creatinine clearance <30 mL/min) and elderly.
Propranolol: 3-6 hours (poor metabolizers up to 10 hours). Hydrochlorthiazide: 6-15 hours (prolonged in renal impairment).
Primarily renal (≥95% as unchanged drug); negligible biliary/fecal elimination (<5%).
Renal elimination of propranolol and hydrochlorthiazide: propranolol is extensively metabolized in the liver, <1% excreted unchanged in urine; hydrochlorthiazide is excreted unchanged in urine (≥95% renal).
