BISOPROLOL FUMARATE AND HYDROCHLOROTHIAZIDE vs TRICHLOREX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bisoprolol is a cardioselective beta-1 adrenergic receptor antagonist that reduces heart rate and myocardial contractility, decreasing cardiac output. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium-chloride symporter in distal convoluted tubule, reducing plasma volume.
Trichlorex is a thiazide-like diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption and increasing water excretion.
One tablet orally once daily. Initial dose: 2.5 mg/6.25 mg to 10 mg/25 mg, titrated based on response. Maximum: 20 mg/50 mg per day.
Oral: 500 mg once daily after the evening meal; sustained-release: 500 mg once daily at bedtime.

Bisoprolol: terminal half-life 10-12 hours (up to 15 hours in elderly/clinically significant for once-daily dosing); Hydrochlorothiazide: terminal half-life 6-15 hours (prolonged in renal impairment).
Terminal elimination half-life is 8-12 hours in adults; prolonged to 20-30 hours in severe renal impairment (creatinine clearance <30 mL/min).
Bisoprolol: 50% unchanged in urine, remainder as inactive metabolites; Hydrochlorothiazide: 95% unchanged in urine. Fecal elimination: negligible.
Renal (90% as unchanged drug, 10% as trichloroacetic acid and trichloroethanol); minor biliary/fecal (less than 1%).
