LOXITANE IM vs MILPROSA
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.
Milprosa is a progesterone receptor agonist that induces and maintains endometrial receptivity, inhibits uterine contractions, and suppresses gonadotropin release.
Adults: 12.5-50 mg IM every 4-6 hours as needed, not to exceed 150 mg/day.
MILPROSA is not a recognized drug; assuming a typo for milrinone? If milrinone: IV loading dose 50 mcg/kg over 10 minutes, then continuous IV infusion 0.375-0.75 mcg/kg/min.

Primarily renal: 70% as metabolites; biliary/fecal: 30% as metabolites and unchanged drug.
