MECAMYLAMINE HYDROCHLORIDE vs SERPALAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Mecamylamine is a noncompetitive antagonist of nicotinic acetylcholine receptors (nAChRs) with highest affinity for α3β4 and α4β2 subtypes. It blocks ganglionic transmission in both sympathetic and parasympathetic ganglia, leading to decreased catecholamine release and antihypertensive effects.
Selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by blocking the reuptake of serotonin at the presynaptic terminal.
Initially 2.5 mg orally twice daily, gradually increased by 2.5 mg increments at intervals of 2 or more days; usual maintenance dose 25 mg/day in divided doses.

Terminal elimination half-life is approximately 12-24 hours; clinically, this allows once or twice daily dosing but requires dose adjustment in renal impairment.
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: 50-70% unchanged; biliary/fecal: minimal (less than 5%)
Primarily renal elimination (60-70% unchanged drug), with 20-30% biliary/fecal excretion as metabolites; less than 10% excreted unchanged in feces.
