BRINSUPRI vs LISINOPRIL AND HYDROCHLOROTHIAZIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BRINSUPRI is a novel oral cyclin-dependent kinase (CDK) inhibitor that selectively inhibits CDK4 and CDK6, thereby blocking phosphorylation of the retinoblastoma (Rb) protein and preventing G1-to-S phase cell cycle progression. This induces cell cycle arrest in cancer cells with intact Rb function.
Lisinopril is an ACE inhibitor that prevents conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium reabsorption in the distal convoluted tubule, increasing diuresis and lowering blood pressure.
4 mg orally once daily, with or without food.
Initial dose: 10 mg/12.5 mg orally once daily. Titrate based on blood pressure response; maximum 40 mg/25 mg per day.

Terminal elimination half-life is approximately 20-30 hours in healthy adults, allowing once-daily dosing. In renal impairment (CrCl <30 mL/min), half-life may extend to >50 hours, requiring dose adjustment.
Lisinopril: terminal half-life 12 hours, effective half-life ~30 hours due to prolonged ACE inhibition. Hydrochlorothiazide: terminal half-life 5.6-14.8 hours (mean 9.6 hours) in patients with normal renal function.
Primarily renal excretion as unchanged drug (70-85%) and minor fecal elimination (10-15%). Biliary excretion accounts for <5%.
Lisinopril: primarily renal (100% unchanged in urine). Hydrochlorothiazide: renal (≥95% unchanged via tubular secretion).
