HISPRIL vs OPTIMINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
HISPRIL (lisinopril) is an angiotensin-converting enzyme (ACE) inhibitor that blocks the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion, leading to decreased blood pressure and afterload.
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.
10 mg orally once daily, increased to 20 mg once daily after 2-4 weeks if needed.
1 mg orally twice daily; maximum 4 mg/day.

The terminal elimination half-life of HISPRIL is approximately 12-15 hours in patients with normal renal function, supporting twice-daily dosing. In moderate to severe renal impairment (CrCl <30 mL/min), half-life is prolonged up to 30-40 hours, necessitating dose interval adjustment.
Terminal elimination half-life of 12-15 hours in healthy adults, prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
HISPRIL is predominantly excreted renally, with approximately 60-70% of an administered dose recovered unchanged in urine over 48 hours. Hepatic metabolism accounts for <10% of elimination, and fecal excretion contributes <5%.
Renal: 65-75% as unchanged drug; biliary/fecal: 20-30% as metabolites; minor hepatic metabolism via CYP3A4.
