APRESOLINE-ESIDRIX vs CONSENSI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Apresoline (hydralazine) is a direct-acting vasodilator that relaxes arteriolar smooth muscle via unknown mechanism; Esidrix (hydrochlorothiazide) is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule.
Consensi is a fixed-dose combination of amlodipine, a dihydropyridine calcium channel blocker, and celecoxib, a nonsteroidal anti-inflammatory drug (NSAID) that selectively inhibits cyclooxygenase-2 (COX-2). Amlodipine inhibits calcium ion influx across cardiac and vascular smooth muscle cells, leading to vasodilation and reduced blood pressure. Celecoxib inhibits prostaglandin synthesis via COX-2, reducing inflammation and pain.
Hydralazine (Apresoline): Oral, initial 10 mg 4 times daily for first 2-4 days, then increase to 25 mg 4 times daily for first week, then 50 mg 4 times daily thereafter. Maximum daily dose: 300 mg. Hydrochlorothiazide (Esidrix): Oral, initial 12.5-25 mg once daily, may increase to 50 mg once daily if needed.
Adults: 0.25 mg/kg intravenously over 1 hour every 2 weeks.

Hydralazine: 2-8 h (prolonged in renal impairment); Hydrochlorothiazide: 6-15 h (mean 10 h, increased in renal failure).
Terminal elimination half-life of 12-15 hours for parent drug and 18-24 hours for active metabolite, allowing once-daily dosing.
Renal: Hydralazine 85-90% as metabolites, 5-10% unchanged; Hydrochlorothiazide 95% as unchanged drug. Biliary/fecal: Hydralazine <10%.
Primarily renal (70-80% as unchanged drug and active metabolite desmethyl-consensi); biliary/fecal: 15-20%.
