Interactions between your drugs

Moderate

butorphanol osilodrostat

Applies to: butorphanol and osilodrostat

MONITOR: Coadministration with osilodrostat may increase the plasma concentrations of drugs that are metabolized by CYP450 1A2, 2C19, 2D6, and/or 3A4. Osilodrostat has been shown to be a moderate inhibitor of CYP450 1A2, a mild to borderline moderate inhibitor of CYP450 2C19, and a weak inhibitor of CYP450 2D6 and 3A4. In a pharmacokinetic study with 20 healthy volunteers using a single 50 mg dose of osilodrostat and a probe drug cocktail, osilodrostat increased the exposures to caffeine (CYP450 1A2 substrate), omeprazole (CYP450 2C19 substrate), dextromethorphan (CYP450 2D6 substrate), and midazolam (CYP450 3A4/5 substrate) by 2.5-, 1.9-, 1.5- and 1.5-fold, respectively.

MANAGEMENT: Caution is advised when osilodrostat is used concurrently with drugs that are substrates of CYP450 1A2, 2C19, 2D6 and/or 3A4, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever osilodrostat is added to or withdrawn from therapy.

Drug and food interactions

Moderate

butorphanol food

Applies to: butorphanol

GENERALLY AVOID: Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

MANAGEMENT: Concomitant use of opioid analgesics with ethanol should be avoided.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
