loxapine + lorazepam

**Loxapine + lorazepam** is a combination therapy consisting of two distinct pharmaceutical agents: loxapine, a first-generation antipsychotic of the dibenzoxazepine class, and lorazepam, a short-acting benzodiazepine. This combination is primarily used for the rapid tranquilization of acute agitation, particularly in psychiatric or behavioral emergencies. - **Loxapine** acts mainly as an antagonist at dopamine D2 and serotonin 5-HT2A receptors, exerting antipsychotic and sedative effects. - **Lorazepam** potentiates GABAergic transmission at GABA-A receptors, producing anxiolytic, muscle relaxant, and sedative actions. When administered together, these drugs provide additive sedative and tranquilizing effects without significant increase in respiratory or cardiovascular adverse outcomes compared to each agent alone (as shown in healthy volunteers receiving IM lorazepam plus inhaled loxapine)[1][2][3]. The combination is commonly used in settings requiring prompt behavioral control (such as emergency rooms or psychiatric wards), but should be used with caution for possible increased CNS depressant effects[1][2][3][5].
