RAUVAL vs SERPANRAY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Rauval (rauwolfia serpentina alkaloids) depletes catecholamines and serotonin from peripheral sympathetic nerve endings and the brain by binding to and inhibiting vesicular monoamine transporters (VMAT), thus reducing sympathetic outflow. This leads to vasodilation, decreased peripheral vascular resistance, and reduced blood pressure.
Serotonin-dopamine activity modulator; partial agonist at 5-HT1A and D2 receptors, antagonist at 5-HT2A receptors.
1.5 mg orally once daily, increased to 3 mg per day if needed. Maximum dose 6 mg per day.
1.5 mg orally once daily at bedtime, titrated up to a maximum of 3 mg once daily.

Terminal elimination half-life is 7-10 hours in normal renal function; prolonged to 14-20 hours in renal impairment, requiring dose adjustment.
Terminal elimination half-life is approximately 62 hours following oral administration, allowing for once-daily dosing.
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%.
Primarily hepatic metabolism via CYP1A2 and CYP3A4, with 18% excreted unchanged in urine and 26% in feces as metabolites.
