Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective antagonist of postsynaptic alpha-1 adrenergic receptors, inhibiting vasoconstriction and reducing peripheral vascular resistance.
Selective antagonist of postsynaptic alpha1A-adrenoceptors in the prostate, bladder base, and prostatic urethra, leading to relaxation of smooth muscle and improved urinary flow.
Initial: 1 mg orally 2-3 times daily. Maintenance: 2-5 mg orally 2-3 times daily. Maximum: 20 mg/day.
10 mg orally once daily, immediately after the same meal each day.

Terminal elimination half-life is 2-3 hours; clinical effect persists longer (up to 24 hours) due to sustained receptor binding.
The terminal elimination half-life is approximately 5 to 9 hours in healthy young subjects, and 6 to 10 hours in elderly patients. This supports once-daily dosing, with steady state achieved after 3-5 days.
Primarily hepatic metabolism (90%) with <10% excreted unchanged in urine; 50-60% of metabolites eliminated in bile/feces, 40-50% in urine.
After oral administration, approximately 11% of the dose is excreted unchanged in urine, while 49% is excreted as metabolites in urine and 22% in feces. Overall, renal elimination accounts for about 60% of total clearance.
