Randomized Controlled Trial Clinical TrialComparative study of the effects of venlafaxine and duloxetine on chemotherapy-induced peripheral neuropathy.
One of the complications of chemotherapy is peripheral neuropathy. Various studies have shown that potent norepinephrine and serotonin reuptake inhibitors such as gabapentin, venlafaxine and duloxetine have therapeutic effects on neuropathy. The aim of this study was to compare the effects of venlafaxine vs. duloxetine on chemotherapy-induced peripheral neuropathy. ⋯ Duloxetine seems to be more effective than venlafaxine in decreasing the symptoms of chemotherapy-induced peripheral neuropathy. Duloxetine was more effective than venlafaxine in decreasing motor neuropathy and neuropathic pain grade.

Biotransformation of [14C]-ixazomib in patients with advanced solid tumors: characterization of metabolite profiles in plasma, urine, and feces.
This metabolite profiling and identification analysis (part of a phase I absorption, distribution, metabolism, and excretion study) aimed to define biotransformation pathways and evaluate associated inter-individual variability in four patients with advanced solid tumors who received [14C]-ixazomib. ⋯ Hydrolytic metabolism in conjunction with oxidative deboronation appears to be the principal process in the in vivo biotransformation pathways of ixazomib. The inference of formation-rate-limited clearance of ixazomib metabolites and the inferred lack of pharmacologic activity of identified circulating metabolites provides justification for use of parent drug concentrations/systemic exposure in clinical pharmacology analyses.
