SELARSDI vs SPRX-105
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective angiotensin II type 1 receptor antagonist that blocks vasoconstriction and aldosterone secretion.
SPRX-105 is a dual dopamine D2 and serotonin 5-HT1A receptor partial agonist, functioning as a postsynaptic antagonist and presynaptic agonist at D2 receptors, and as a partial agonist at 5-HT1A receptors, modulating neurotransmitter release.
Intravenous 0.15 mg/kg every 8 hours for 14 days.
SPRX-105 is administered orally at a dose of 50 mg once daily.

Terminal elimination half-life is approximately 11 hours (range 7–15 hours), supporting twice-daily dosing; half-life may be prolonged in renal impairment.
12-15 hours in healthy adults; extended to 24-30 hours in renal impairment.
Primarily renal excretion of unchanged drug (approximately 70%) and glucuronide conjugate (approximately 20%); biliary/fecal elimination accounts for less than 10%.
Primarily renal (70-80% unchanged) with 15-20% biliary/fecal elimination.
