LOXITANE IM vs LYPQOZET
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LOXITANE IM (loxapine) is a dibenzoxazepine antipsychotic. Its mechanism of action is not fully established but is thought to be mediated via antagonism of central dopamine D2 and serotonin 5-HT2A receptors. It has high affinity for D2, D3, D4, and 5-HT2A receptors and low affinity for D1 receptors. It also has moderate affinity for histamine H1 and alpha1-adrenergic receptors.
LYPQOZET is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the central nervous system by inhibiting the reuptake of serotonin at the presynaptic serotonin transporter, leading to increased synaptic levels of serotonin.
Adults: 12.5-50 mg IM every 4-6 hours as needed, not to exceed 150 mg/day.
Oral, 75 mg once daily.

Terminal elimination half-life: 8-12 hours. Clinically, steady-state reached in 2-3 days; dosing interval based on q6-12h.
Terminal elimination half-life is 22-28 hours in adults, allowing once-daily dosing. Extended half-life supports sustained therapeutic levels.
Primarily renal: 70% as metabolites; biliary/fecal: 30% as metabolites and unchanged drug.
Primarily renal (75% unchanged) and fecal/biliary (20% as metabolites); <5% unchanged in feces.
