BROMPHENIRAMINE MALEATE vs OPTIMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine at H1 receptor sites, suppressing histamine-induced vasodilation, increased capillary permeability, and bronchoconstriction.
OPTIMINE (azathioprine) is a purine analog that inhibits DNA and RNA synthesis by interfering with purine metabolism. It is metabolized to 6-mercaptopurine, which inhibits de novo purine synthesis and suppresses T-lymphocyte proliferation.
4 mg orally every 4-6 hours, not to exceed 24 mg/day. Alternatively, extended-release: 12 mg every 12 hours.
1 mg orally twice daily; maximum 4 mg/day.

Terminal half-life 22-25 hours; prolonged in hepatic impairment or elderly (up to 40 hours).
Terminal elimination half-life of 12-15 hours in healthy adults, prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
Renal (85-90% as metabolites, 5-10% unchanged); biliary/fecal <5%.
Renal: 65-75% as unchanged drug; biliary/fecal: 20-30% as metabolites; minor hepatic metabolism via CYP3A4.
