HYDRO-D vs INDERIDE-80/25
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule, reducing sodium and water reabsorption and increasing potassium excretion.
INDERIDE-80/25 is a combination of propranolol (a non-selective beta-adrenergic receptor antagonist) and hydrochlorothiazide (a thiazide diuretic). Propranolol blocks beta-1 and beta-2 adrenergic receptors, reducing heart rate, myocardial contractility, and renin release, thereby lowering blood pressure. Hydrochlorothiazide inhibits the sodium-chloride symporter in the distal convoluted tubule of the kidney, increasing excretion of sodium, chloride, and water, reducing plasma volume.
25-100 mg orally once daily in the morning.
One tablet (80 mg propranolol/25 mg hydrochlorothiazide) orally twice daily.

Terminal elimination half-life: 5.6 to 15 hours; prolonged in renal impairment and in patients with heart failure.
Propranolol: 3-6 hours (single dose), prolonged with chronic dosing (up to 12 hours). Hydrochlorothiazide: 6-15 hours; prolonged in renal impairment.
Renal: approximately 50% as unchanged drug; biliary/fecal: approximately 50% as metabolites and minor unchanged drug.
Renal: 40% unchanged propranolol; 60% as metabolites. Biliary/fecal: minimal (less than 1%). Hydrochlorothiazide: renal 95% unchanged.
