Evaluation of potential drug–drug interactions with medical cannabis

Abstract Cannabis–drug interactions have caused significant concerns, mainly due to their role in the cytochrome P450 (CYP) enzyme-mediated metabolic pathway of numerous medications. A systematic review was conducted to gain…

Effect of cannabidiol on cytochrome P-450 isozymes

Abstract Cannabidiol (CBD) has been shown to inhibit mouse hepatic mixed-function oxidations of several drugs after acute treatment, whereas repetitive treatment resulted in the restoration of drug-metabolizing capabilities. We have…

A Phase I, open-label, randomized, crossover study in three parallel groups to evaluate the effect of Rifampicin, Ketoconazole, and Omeprazole on the pharmacokinetics of THC/CBD oromucosal spray in healthy volunteers

This Phase I study aimed to assess the potential drug-drug interactions (pharmacokinetic [PK] and safety profile) of Δ9-tetrahydrocannabinol (THC)/cannabidiol (CBD) oromucosal spray (Sativex®, nabiximols) in combination with cytochrome P450 (CYP450)…

Identification of cytochrome P450 enzymes responsible for metabolism of cannabidiol by human liver microsomes

Aims: Cannabidiol (CBD), one of the major constituents in marijuana, has been shown to be extensively metabolized by experimental animals and humans. However, human hepatic enzymes responsible for the CBD…

Mechanism for inhibitory effect of cannabidiol on microsomal testosterone oxidation in male rat liver

Effects of four cannabinoids [cannabidiol (CBD), delta 8-tetrahydrocannabinol, delta 9-tetrahydrocannabinol, and cannabinol] on hepatic microsomal oxidation of testosterone (17 beta-hydroxy-androst-4-ene-3-one) were examined in adult male rats. Only CBD (30 microM)…
