ACCURETIC vs BRINSUPRI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ACCURETIC is a combination of quinapril, an angiotensin-converting enzyme (ACE) inhibitor, and hydrochlorothiazide, a thiazide diuretic. Quinapril inhibits ACE, preventing conversion of angiotensin I to angiotensin II, reducing vasoconstriction and aldosterone secretion. Hydrochlorothiazide inhibits sodium reabsorption in the distal convoluted tubule, increasing diuresis and lowering blood pressure.
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.
One tablet orally once daily. Initial dose is 20 mg quinapril/12.5 mg hydrochlorothiazide, titrated to maximum 20 mg quinapril/25 mg hydrochlorothiazide.
4 mg orally once daily, with or without food.

Quinapril: 0.8 hours; Quinaprilat (active): 2 hours in young healthy adults, prolonged to 3-4 hours in elderly or renal impairment.
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.
Renal: approximately 90% (60% unchanged, 30% as metabolites). Fecal/biliary: <10%.
Primarily renal excretion as unchanged drug (70-85%) and minor fecal elimination (10-15%). Biliary excretion accounts for <5%.
