Medication adherence to obeticholic acid: a real-world experience using medication event monitoring systems.

Objective: We designed a clinical study to analyze patterns of adherence to  obeticholic acid, factors influencing the adherence and potential correlation with  treatment efficacy by using MEMS® cap in practice daily. Method: A multicenter prospective observational study of patients with primary  biliary cholangitis. Adherence will be measured by MEMS® cap, pill count, and  patient-reported outcomes during 3 months.

Impact of CYP2C19 Genotype and Drug Interactions on Voriconazole Plasma Concentrations: A Spain Pharmacogenetic-Pharmacokinetic Prospective Multicenter Study.

Background: Voriconazole, a first-line agent for the treatment of invasive fungal infections, is mainly metabolized by cytochrome P450 (CYP) 2C19. A significant portion of patients fail to achieve therapeutic voriconazole trough concentrations, with a consequently increased risk of therapeutic failure.

Objective: To show the association between subtherapeutic voriconazole concentrations and factors affecting voriconazole pharmacokinetics: CYP2C19 genotype and drug-drug interactions.

Automated therapy preparation of isoleucine formulations using 3D printing for the treatment of MSUD: First single-centre, prospective, crossover study in patients.

Maple syrup urine disease (MSUD) is a rare metabolic disorder with a worldwide prevalence of 1 in every 185,000 live births. However, certain populations display a significant overexpression of the disorder where incidence is reported to be 1 in every 52,541 new-borns. The first-line therapy for MSUD involves a strict dietary leucine restriction and oral supplementation of isoleucine and valine.
