Interaction Details

Amitriptyline, Chlordiazepoxide is classified as belonging to the following category: Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, Rauvolfia vomitoria might increase the levels and clinical effects of CYP2D6 substrates.
Rauvolfia vomitoria contains small amounts of the drug yohimbine. In vitro research shows that yohimbine inhibits CYP2D6 enzyme activity.

Interaction Details

Amitriptyline, Chlordiazepoxide is classified as belonging to the following category: Tricyclic Antidepressants (Tcas)

Theoretically, concomitant use might alter the effects of Rauvolfia vomitoria and increase the risk for adverse effects.
A small clinical study in patients taking TCAs for at least 4 weeks shows that receiving doses of intravenous yohimbine, a constituent of Rauvolfia vomitoria, 2.5-20 mg daily for up to 7 days precipitates severe anxiety, agitation, and tremor. Also, concomitant use of TCAs with Rauvolfia vomitoria may decrease the effects of rauwolfia alkaloids.

Interaction Rating

Likelihood of Occurrence

Interaction 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.
