RISVAN vs SEZABY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Risperidone is an atypical antipsychotic that acts as a serotonin 5-HT2A and dopamine D2 receptor antagonist. It also binds to alpha1-adrenergic and H1 histaminergic receptors.
Positive allosteric modulator of GABA-A receptors, enhancing inhibitory neurotransmission.
70 mg orally once daily, with or without food.
58 mg subcutaneously once monthly (every 30 days).

Terminal elimination half-life: 12-15 hours in healthy adults; prolonged to 20-30 hours in hepatic impairment (Child-Pugh B/C).
The terminal elimination half-life of Sezaby is approximately 24 hours in healthy adults. This supports once-daily dosing. In patients with hepatic impairment, half-life may be prolonged.
Renal: 30% unchanged; Fecal: 65% (biliary excretion of metabolites); 5% other.
Sezaby undergoes extensive hepatic metabolism, with approximately 75% of the dose excreted in feces as metabolites and 20% in urine as unchanged drug and metabolites. Renal clearance accounts for less than 5% of total clearance.
