Oral esketamine displays therapeutic potential for treatment-resistant depression. However, treatment is complicated by a low and variable bioavailability. Genetic polymorphisms in the cytochrome P450 (CYP) enzymes responsible for esketamine's metabolism may influence bioavailability. In a subsample of patients included in a placebo-controlled trial investigating repeated, low dose oral...
Oral esketamine is a promising new therapy for treatment-resistant depression. However, concerns exist about interindividual pharmacokinetic variability. Genetic polymorphisms regulating the expression of ATP-binding cassette (ABC) transporters might influence bioavailability. Utilizing blood samples from a placebo-controlled trial investigating repeated, low dose oral esketamine (N = 18), we...
