HISPRIL vs HYDROXYZINE
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.
Hydroxyzine is a first-generation antihistamine that acts as a competitive antagonist at histamine H1 receptors in the gastrointestinal tract, blood vessels, and respiratory tract. It also exhibits sedative, anxiolytic, and antiemetic properties, possibly through central nervous system depression and anticholinergic effects.
10 mg orally once daily, increased to 20 mg once daily after 2-4 weeks if needed.
25-100 mg orally 3-4 times daily; 50-100 mg IM every 4-6 hours as needed. Maximum oral dose: 600 mg/day in divided doses.

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: 14-25 hours (mean ~20 h). In elderly or hepatic impairment, may be prolonged; antihistamine effect persists beyond half-life due to active metabolite.
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: approximately 70% as metabolites, less than 1% unchanged. Fecal/biliary: minor. Cetirizine (active metabolite) also renally eliminated.
