Relationship Between Serum Ustekinumab Trough Concentration and Clinical and Biochemical Disease Activity: A Real-World Study in Adult Patients with Crohn ’s Disease
ConclusionsIn this study, dosing interval was the only determinant significantly associated with a higher UTC for patients on maintenance ustekinumab therapy. While a higher UTC may be achieved with dose escalation, it was not associated with improved rates of clinical or biochemical response in our cohort.

Population Pharmacokinetic and Pharmacodynamic Modeling of Fesoterodine in Pediatric Patients  with Neurogenic Detrusor Overactivity
ConclusionsPopulation models were developed for 5-HMT and MCC in pediatric  patients. Weight-based simulations indicated that 4 mg QD for pediatric patients weighing 25–35 kg and 8 mg QD for those weighing> 35 kg provided similar exposures to those in adults following 8 mg QD and a clinically meaningful CFB MCC.Clinical Trial NumbersNCT00857896, NCT01557244 (Source: European Journal of Drug Metabolism and Pharmacokinetics)

Neurotherapeutic Effects of Quercetin and Its Metabolite Compounds on Cognitive Impairment and Parkinson ’s Disease: An In Silico Study
ConclusionThis study identified 28 quercetin metabolite products. The metabolites have similar characteristics to quercetin such as physicochemical properties, absorption, distribution, metabolism, and excretion (ADME), and biological activities. More research, especially clinical trials, is needed to find out how quercetin and its metabolites protect against CI and PD.Graphical Abstract (Source: European Journal of Drug Metabolism and Pharmacokinetics)

Characterization of the Stereoselective Disposition of Bupropion and Its Metabolites in Rat Plasma and Brain
ConclusionsThe temporal shift inKp,uu among the different molecular forms provides evidence regarding the operation of carrier-mediated transport and/or within-brain metabolism of bupropion, and, thereby, fresh insight regarding the causes of intersubject variability in the safety and efficacy of bupropion therapy.
