Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Sulfonylurea that stimulates insulin secretion from pancreatic beta cells by binding to the sulfonylurea receptor (SUR1) on ATP-sensitive potassium channels, causing channel closure and calcium influx.
Sulfonylurea that stimulates insulin secretion from pancreatic beta cells by blocking ATP-sensitive potassium channels, leading to membrane depolarization and calcium influx.
Initial dose 1-2 mg orally once daily, titrated to target glucose. Maximum dose 8 mg daily.
Initial dose: 250 mg orally once daily with breakfast; maintenance dose: 250-500 mg orally once daily; maximum dose: 1000 mg per day.

Terminal elimination half-life is 5-7 hours; clinically, dosing is once daily due to sustained glucose-lowering effect beyond half-life.
Terminal elimination half-life is 6-10 hours; clinically significant as it supports once-daily dosing.
Approximately 60% excreted renally as metabolites (mainly M1 and M2) and 40% in feces; <1% excreted unchanged.
Primarily renal excretion of metabolites and unchanged drug (approximately 70-80%), with biliary/fecal excretion accounting for 10-20%.
