SEPHIENCE vs UZEDY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
SEPHIENCE (pegfilgrastim) is a recombinant human granulocyte colony-stimulating factor (G-CSF) analog. It binds to G-CSF receptors on hematopoietic cells, stimulating proliferation, differentiation, and release of neutrophils from bone marrow.
Atypical antipsychotic; antagonist at dopamine D2 and serotonin 5-HT1A/5-HT2A receptors; partial agonist at serotonin 5-HT1A receptors
Adults: 200 mg orally twice daily with food.
UZEDY (risperidone) extended-release injectable suspension: 75 mg, 100 mg, 150 mg, or 200 mg IM gluteal injection every 2 weeks after a single oral dose of 2 mg risperidone for 2 days; or 25 mg, 50 mg, 75 mg, 100 mg, 125 mg, or 150 mg IM every 4 weeks after oral overlap for 2 days. Oral risperidone may be omitted if patient is stable on oral risperidone 2 mg/day.

Terminal elimination half-life is 12-15 hours in healthy adults, allowing for twice-daily dosing. Half-life may be prolonged in renal impairment (up to 30 hours in severe cases).
Terminal half-life approximately 30 days (range 23–37 days) after subcutaneous injection, supporting monthly dosing.
SEPHIENCE is primarily eliminated via renal excretion (approximately 70% as unchanged drug) and biliary/fecal excretion (approximately 25% as metabolites and unchanged drug).
Primarily renal: 80% as metabolites, 1% unchanged. Biliary/fecal: 20%.
