Olanzapine/samidorphan

Olanzapine/samidorphan (OLZ/SAM), sold under the brand name Lybalvi, is a fixed-dose combination medication for the treatment of schizophrenia and bipolar I disorder.[1] It contains olanzapine, an atypical antipsychotic, and samidorphan, an opioid antagonist.[1][2][3] Samidorphan reduces the weight gain associated with olanzapine while still allowing olanzapine to exert its therapeutic effect.[4][5] The formulation was approved for medical use in the United States in May 2021.[1][6]
