Pharmacogenetics of artemether ‐lumefantrine influence on nevirapine disposition: clinically significant drug‐drug interaction?
ConclusionsThis approach highlights additional increase in the already existing risk of suboptimal trough plasma concentration, especially in extensive metabolisers when nevirapine is co ‐administered with artemether‐lumefantrine. (Source: British Journal of Clinical Pharmacology)

Update on pharmacologically ‐relevant vitamin D analogues
Pharmacologists have been interested in vitamin D since its metabolism was elucidated in the early 1970s. Despite the synthesis of thousands of vitamin D analogues in the hope of separating its calcemic and anti ‐proliferative properties, few molecules have reached the market for use in the treatment of clinical conditions from psoriasis to chronic kidney disease. This review discusses vitamin D drugs, recently developed or still under development, for use in various diseases, but in particular bone disea se. In the process we explore the mechanisms postulated to explain the action of these vitamin D analogues including ...

Integrating anatomo ‐physiological changes and pharmacogenomics in anti‐infective therapy management: is it a major concern?
Success of anti ‐infective therapy is a major challenge in some patients given anatomo‐physiological changes and genetic variations. In this case anecdote, we report the management strategy of a patient suffering from chronic pulmonary aspergillosis in a context of anorexia nervosa and genetic polymorphism.

Plasma extracellular nanovesicle (exosome) ‐derived biomarkers for drug metabolism pathways: a novel approach to characterize variability in drug exposure
ConclusionsConsistent strong concordance was observed between exosome ‐derived CYP3A4 biomarkers and midazolam CL/F. The significance of these results is that CYP3A4 is the drug‐metabolizing enzyme of greatest clinical importance and variability in CYP3A4 activity is poorly described by existing precision dosing strategies.

Physiologically ‐based pharmacokinetic modelling to predict oprozomib CYP3A drug‐drug interaction potential in patients with advanced malignancies
ConclusionsThese results indicate oprozomib has a low potential to inhibit the metabolism of CYP3A4 substrates in humans. The study shows that cultured human hepatocytes are a more reliable system for DDI prediction than human liver microsomes for studying this class of compounds. Developing a PBPK model prior to a clinical DDI study has been valuable in supporting clinical development of oprozomib. (Source: British Journal of Clinical Pharmacology)

Comparative safety and effectiveness of direct oral anticoagulants in patients with atrial fibrillation in clinical practice in Scotland
ConclusionsAll DOACs were similarly effective in preventing strokes and systemic embolisms, while patients being treated with rivaroxaban exhibited the highest bleeding risks.

Prolonged central apnoea after intravenous morphine administration in a 12 ‐year‐old male with a UGT1A1 loss‐of‐function polymorphism
Adverse eventRepeated and prolonged episodes of central apnoea and hypoxia after receiving intravenous morphine for analgesia and ketamine for sedation.Drug implicatedIntravenous morphine sulfate.The patientPreviously healthy 12 ‐year‐old male with no history of sleep apnoea who presented with distal tibia and fibula fracture.Evidence that links drug to eventPharmacogenomic testing revealed that the patient was homozygous for the T allele at the rs887829 SNP inUGT1A1, an enzyme involved in the metabolism of morphine. This polymorphism is a loss ‐of‐function variant, leading to impaired metabolism of morphine.Mechan...
