Obesity significantly influences drug pharmacokinetics (PK), which challenges optimal dosing. This study examines the effects of diet-and-exercise-induced weight loss on key drug-metabolizing enzymes and gastric emptying in patients with obesity, who frequently require medications for comorbidities. Participants followed a structured weight management program promoting weight loss over 3-6 months and were not concomitantly on potential CYP inducers or inhibitors.

Background: Due to its exceptional effectiveness, clozapine (CLO), whose metabolite is norclozapine (NCLO), is a drug of choice in the management of treatment-resistant schizophrenia. The purpose of this study was to assess the factors modifying the CLO/NCLO ratio (CNR).
Methods: A total of 446 blood samples (233 of which were drawn from females and 213 from males, aged from 18 to 77 years) were analyzed in this study.

Background And Objective: N,N-Dimethyltryptamine (DMT) is currently being studied for its therapeutic potential in various psychiatric disorders. An understanding of its pharmacokinetics (PK) is essential to determine appropriate dose ranges in future clinical studies. We conducted a systematic literature review on the PK of DMT.

Purpose: The primary objectives of this trial were aimed at exploring the pharmacokinetic profiles and the human bioequivalence of an intravenous liposomal injection of doxorubicin hydrochloride in comparison with a reference formulation in Chinese patients diagnosed with metastatic breast cancer.
Methods: To achieve these goals, the trial employed a randomized, open-label, two-formulation crossover dosing strategy among Chinese patients with metastatic breast cancer. Pharmacokinetic (PK) evaluation was conducted through the collection of blood samples, and the liquid chromatography tandem mass spectrometry (LC/MS/MS) method was leveraged to quantify plasma concentrations of both liposome-encapsulated doxorubicin and non-encapsulated doxorubicin in patients.

Immune checkpoint blockers (ICBs) have revolutionized the treatment of non-small cell lung cancer (NSCLC). Currently, one-dose-fits-all maximalist regimens have been considered the standard of care, with ICBs administered at flat doses regardless of patients' weight. Treatment duration with ICBs is often arbitrary across stages, ranging from a fixed time point to until disease progression or unacceptable toxicity.
