SERPASIL vs TEKTURNA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Reserpine (Serpasil) is an indole alkaloid that depletes catecholamines (norepinephrine, dopamine) and serotonin from central and peripheral nerve endings by irreversibly binding to and inhibiting the vesicular monoamine transporter (VMAT), preventing storage of monoamines in presynaptic vesicles, leading to depletion and reduced sympathetic outflow.
Direct renin inhibitor that binds to renin, inhibiting the conversion of angiotensinogen to angiotensin I, thereby reducing angiotensin II levels and decreasing vasoconstriction and aldosterone secretion.
Hypertension: 0.1–0.25 mg orally once daily; initial dose 0.1 mg, maximum 0.5 mg/day. Psychosis (not first-line): 0.5–2 mg orally daily.
150 mg orally once daily, starting dose; may increase to 300 mg once daily after 2-4 weeks if blood pressure not controlled, with or without food.

Terminal elimination half-life 45–168 hours (mean 100 h), reflecting prolonged adrenergic depletion; clinical effects persist beyond serum presence.
Terminal elimination half-life is approximately 24 hours (range 20–40 hours), supporting once-daily dosing.
Primarily renal (approx. 60% unchanged and metabolites), biliary/fecal (approx. 40%), enterohepatic circulation negligible.
Primarily renal (88% as unchanged drug and metabolites, 33% as unchanged aliskiren); biliary/fecal elimination accounts for approximately 12%.
