Pharmacokinetic Evaluation of a Cinnamon Product on CYP2A6 Substrate Drugs: Application of a Novel Tool Involving the Nicotine Metabolite Ratio

Clinical Pharmacology &Therapeutics, EarlyView.
Cinnamon (Cinnamomum spp.) is used as a culinary spice and dietary supplement. A major constituent, cinnamaldehyde, was previously shown to inactivate cytochrome P450 (CYP) 2A6 in vitro. A mechanistic static model predicted an ~5‐fold increase in the AUC of the CYP2A6 substrates nicotine and letrozole.

Pharmacokinetic Drug–Drug Interaction Potential of Oral Anticancer Drugs

Clinical Pharmacology &Therapeutics, EarlyView.
Drug–drug interaction (DDI) management is critical for safe and effective use of oral anticancer drugs (OADs). Our study objectives were to (i) compile clinically relevant pharmacokinetic (PK) DDI mechanisms for OADs and (ii) assess the prevalence of PK potential DDIs (PDDIs) in patients with advanced solid cancers.
