PALIPERIDONE vs UZEDY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Paliperidone is an atypical antipsychotic that exerts its effects primarily through antagonism of central dopamine D2 receptors and serotonin 5-HT2A receptors. It also antagonizes alpha-1 and alpha-2 adrenergic receptors, and H1 histaminergic receptors. Paliperidone is the major active metabolite of risperidone.
Atypical antipsychotic; antagonist at dopamine D2 and serotonin 5-HT1A/5-HT2A receptors; partial agonist at serotonin 5-HT1A receptors
6 mg orally once daily, with dose adjustments in 3 mg increments at intervals of 5 days or more; usual effective range 3-12 mg/day.
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.
