Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective dopamine D2 receptor antagonist; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
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.
Adults: 1 mg orally once daily.
1 mg orally twice daily; maximum 4 mg/day.

12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
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: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
Renal: 65-75% as unchanged drug; biliary/fecal: 20-30% as metabolites; minor hepatic metabolism via CYP3A4.
