SECUADO vs UZEDY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
SECUADO (asenapine) is an atypical antipsychotic with high affinity for serotonin 5-HT2A, 5-HT2C, 5-HT6, and 5-HT7 receptors, as well as dopamine D2, D3, and D4 receptors. It also exhibits moderate affinity for histamine H1 and alpha2-adrenergic receptors, and low affinity for alpha1 and muscarinic receptors. The therapeutic effect in schizophrenia and bipolar disorder is primarily mediated through antagonism at D2 and 5-HT2A receptors.
Atypical antipsychotic; antagonist at dopamine D2 and serotonin 5-HT1A/5-HT2A receptors; partial agonist at serotonin 5-HT1A receptors
Adults: 3.8 mg/24 hours applied transdermally once daily; initially 3.8 mg/24 hours, may titrate to 5.7 mg/24 hours, 7.6 mg/24 hours, or 11.4 mg/24 hours based on tolerability and efficacy. Maximum dose: 11.4 mg/24 hours.
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.
