RAUVAL vs SERPALAN
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.
Selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by blocking the reuptake of serotonin at the presynaptic terminal.
1.5 mg orally once daily, increased to 3 mg per day if needed. Maximum dose 6 mg per day.
100 mg orally twice 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 12-14 hours in adults with normal renal function; prolonged to 24-36 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 60 hours in severe renal impairment (CrCl <30 mL/min).
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 20-30%.
Primarily renal elimination (60-70% unchanged drug), with 20-30% biliary/fecal excretion as metabolites; less than 10% excreted unchanged in feces.
