Cannabidiol (cbd) - Asenapine Interaction Details

Interaction Details

Asenapine is classified as belonging to the following category: Cytochrome P450 1A2 (Cyp1A2) Substrates

Cannabidiol may increase levels of drugs metabolized by CYP1A2.
In vitro research shows that cannabidiol inhibits CYP1A2. Furthermore, clinical studies show that cannabidiol may inhibit the metabolism of caffeine, a CYP1A2 substrate. Two pharmacokinetic studies in healthy adults show that taking cannabidiol dosed 640 mg once up to 750 twice daily increases the area under the curve of caffeine. However, results are mixed over whether cannabidiol impacts peak serum levels of caffeine.

Interaction Rating

Asenapine Overview

Asenapine is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Asenapine is used alone or in combination with other medications to treat or prevent episodes of mania (frenzied, abnormally excited mood) or mixed mania (frenzied, abnormally excited mood and symptoms of depression) in adults and children 10 years of age and older with bipolar I disorder (manic depressive disorder; a disease that causes episodes of mania, episodes of depression and other abnormal moods). Asenapine is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.
