Interaction Details
Chlordiazepoxide, Clidinium Bromide is classified as belonging to the following category: Cns Depressants
Theoretically, cannabidiol might have additive effects if used with other CNS depressants.
Preliminary clinical research, case reports, and animal studies suggest that high dose cannabidiol has sedative and hypnotic effects. Theoretically, concomitant use of cannabidiol with drugs with sedative and anesthetic properties may cause additive therapeutic and adverse effects.

Likelihood of Occurrence
PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists

Interaction Details
Chlordiazepoxide, Clidinium Bromide is classified as belonging to the following category: Cytochrome P450 1A2 (Cyp1A2) Substrates
Cannabidiol can increase levels of drugs metabolized by CYP1A2.
In vitro research shows that cannabidiol inhibits CYP1A2. Furthermore, cannabidiol has been shown to inhibit the metabolism of caffeine, a CYP1A2 substrate, in humans. A pharmacokinetic study in healthy adults shows that taking cannabidiol, starting at 250 mg once daily and titrating to 750 twice daily over a total of 24 days, increases the peak serum level of caffeine by 15% and the overall exposure to caffeine by 95% after a single dose of caffeine 200 mg taken on day 23.

Likelihood of Occurrence
ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
