CONSENSI vs RAUTENSIN
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.
Combination of Rauwolfia serpentina alkaloids (e.g., reserpine) that deplete catecholamines and serotonin from peripheral sympathetic nerve endings and brain, reducing total peripheral resistance and cardiac output.
Adults: 0.25 mg/kg intravenously over 1 hour every 2 weeks.
1-2 tablets (each containing Rauwolfia serpentina 50 mg and flumethiazide 0.5 mg) orally once daily.

Terminal elimination half-life of 12-15 hours for parent drug and 18-24 hours for active metabolite, allowing once-daily dosing.
The terminal elimination half-life of rauwolfia alkaloids is approximately 50-100 hours, with a mean of about 72 hours. This long half-life supports once-daily dosing and leads to slow accumulation and sustained antihypertensive effect.
Primarily renal (70-80% as unchanged drug and active metabolite desmethyl-consensi); biliary/fecal: 15-20%.
Rautensin (rauwolfia alkaloids) is primarily excreted via hepatic metabolism and biliary-fecal elimination, with less than 1% excreted unchanged in urine. Renal excretion accounts for approximately 10% of metabolites, while biliary/fecal elimination accounts for approximately 90%.
