CONSENSI vs EXFORGE HCT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
EXFORGE HCT is a combination of amlodipine (a dihydropyridine calcium channel blocker), valsartan (an angiotensin II receptor blocker), and hydrochlorothiazide (a thiazide diuretic). Amlodipine inhibits calcium ion influx across cardiac and vascular smooth muscle cells, leading to vasodilation. Valsartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II. Hydrochlorothiazide increases excretion of sodium and water by inhibiting the Na+/Cl- symporter in the distal convoluted tubule.
Adults: 0.25 mg/kg intravenously over 1 hour every 2 weeks.
One tablet orally once daily. Initial dose based on previous antihypertensive therapy; maximum dose is one tablet of 10 mg amlodipine/320 mg valsartan/25 mg hydrochlorothiazide per day.

Terminal elimination half-life of 12-15 hours for parent drug and 18-24 hours for active metabolite, allowing once-daily dosing.
Valsartan: 6 hours (terminal). Amlodipine: 30-50 hours (terminal), permits once-daily dosing. Hydrochlorothiazide: 6-15 hours (terminal).
Primarily renal (70-80% as unchanged drug and active metabolite desmethyl-consensi); biliary/fecal: 15-20%.
Valsartan: 13% excreted unchanged in urine, 83% in feces via biliary secretion. Amlodipine: 10% excreted unchanged in urine, 60% as metabolites in urine, 20-25% in feces. Hydrochlorothiazide: ≥95% excreted unchanged in urine.
