HYDRO-RX vs ZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing sodium and chloride reabsorption, leading to increased diuresis, decreased plasma volume, and vasodilation. It also reduces peripheral vascular resistance.
Hydrochlorothiazide is a thiazide diuretic that inhibits the sodium-chloride symporter in the distal convoluted tubule of the nephron, reducing reabsorption of sodium and chloride and increasing excretion of water, sodium, chloride, potassium, and bicarbonate.
Initial: 25 mg orally once daily; may increase to 50 mg once daily after 2 weeks based on response. Maximum: 50 mg daily.
10 mg orally once daily.

Clinical Note
moderateTerminal elimination half-life is 8-12 hours in adults with normal renal function; extended to 20-30 hours in severe renal impairment (CrCl <30 mL/min).
6-8 hours in normal renal function; prolonged to 20-40 hours in severe renal impairment (eGFR <30 mL/min).
Renal excretion of unchanged drug accounts for 60% of elimination; biliary/fecal excretion accounts for 30%; 10% metabolized.
Renal: 70% unchanged; Biliary/fecal: 30% (as metabolites and parent compound).
