HISPRIL vs MYMETHAZINE FORTIS
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.
Mymethazine fortis is a phenothiazine derivative that exerts antipsychotic and antiemetic effects primarily by blocking postsynaptic dopamine D2 receptors in the mesolimbic system, as well as possessing anticholinergic, antihistaminergic, and alpha-adrenergic antagonistic properties.
10 mg orally once daily, increased to 20 mg once daily after 2-4 weeks if needed.
50 mg orally every 6 hours as needed for nausea and vomiting.

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 is 15-20 hours; in renal impairment (CrCl <30 mL/min), may extend to 30-40 hours, requiring dose adjustment.
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%.
Primarily renal (70-80% as unchanged drug and metabolites, with about 30% as unchanged); fecal (10-15%) via biliary elimination.
