RISVAN vs SECUADO
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.
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.
70 mg orally once daily, with or without food.
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.
