CHLORTHALIDONE vs MICROZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Thiazide-like diuretic; inhibits sodium-chloride cotransporter in distal convoluted tubule, increasing excretion of sodium, chloride, and water. Also lowers peripheral vascular resistance.
Inhibits the sodium-chloride symporter (NCC) in the distal convoluted tubule of the nephron, reducing reabsorption of sodium and chloride, leading to increased excretion of water and electrolytes, and a decrease in blood volume and peripheral vascular resistance.
Oral: 25-100 mg once daily; initial dose 25 mg once daily; may increase to 50-100 mg once daily based on response.
12.5-25 mg orally once daily for hypertension; 25-100 mg orally once daily for edema.
