Introduction Three psychotropic drug classes, benzodiazepines, antiepileptic drugs (AEDs) and antidepressants (ADs), whether used in treatment or overdose, may be associated with respiratory aspiration. Polypharmacy was defined by counting suspected drugs from these classes or two others, antipsychotics and opioids. The confounding effects of polypharmacy were considered in this study. Areas covered VigiBase records of respiratory aspiration associated with benzodiazepines, AEDs, and/or ADs from inception until 5 September 2021, were reviewed. VigiBase, the World Health Organization’s global pharmacovigilance database, uses a statistical signal for associations called the information component (IC). Expert Opinion The ICs (and IC025) were benzodiazepines 2.8 (and 2.6), AEDs 1.6 (and 1.5), and ADs 1.4 (and 1.3). The cases of respiratory aspiration associated with at least one drug from these 3 classes included: 1) 553 cases absent any known overdose (2.8 ± 1.7 drugs) and 2) 347 overdose cases (2.9 ± 1.8 drugs). Little support for the association of respiratory aspiration and benzodiazepine, AED or AD monotherapy in therapeutic dosages was found. Studies of the association between benzodiazepine monotherapy and respiration aspiration are needed in geriatric patients. ADs added to other medications increased lethality in all cases of respiratory aspiration including those associated with overdose, polypharmacy and/or major medical problems.

Introduction Idiosyncratic drug-induced liver injury (iDILI) is a challenging and unpredictable multifactorial condition. At present, validated preclinical models for the prediction of the hepatotoxic potential of a given drug are scarce. Areas covered This review intends to sum up the current knowledge about in vitro (including hepatocyte 2D cultures, cocultures with non-parenchymal cells, 3D configurations and non-typical closer to reality in vitro models), in vivo (covering models for immunological and oxidative stress features, humanized mouse-based and non-rodent models) and in silico approaches for iDILI modeling, highlighting the recent advances in each topic. Expert opinion The future strategy for iDILI modeling should be patient-centered. Future animal and cell-based models, with more predictive value, will be easier to design by using a more translational approach based on mechanisms demonstrated in humans. Genetic and epigenetic information gathered from iDILI patients, together with data from in vitro and in vivo studies, could be used to develop sophisticated predictive in silico models to find compounds with iDILI potential. Collecting genetic, metabolic, and biomarker data from patient cohorts might be another option to create a ‘fingerprint’ characteristic of people at risk, allowing for the development of new, mechanistic strategies to enhance iDILI in vitro evaluation.

Introduction Levetiracetam (LEV) is one of the most widely used anti-seizure medications (ASMs) in clinical practice. This is due both to a different mechanism of action when compared to other ASMs and its easy handling. Indeed, because of its interesting pharmacokinetic properties, it is often used outside of the labeled indications, notably in the neurocritical setting as prophylaxis of epileptic seizures. Areas covered A literature search was conducted and the most relevant studies on the pharmacokinetic properties of LEV were selected by two independent investigators. Current evidence on the use of ASM prophylaxis in the neurocritical setting was also reviewed, highlighting and discussing the strengths and limits of LEV as drug of choice for anti-epileptic prophylaxis in this scenario. Expert opinion LEV has a ‘near-ideal’ pharmacokinetic profile, which makes it an attractive drug for ASM prophylaxis in neurocritical care. However, current recommendations restrict ASMs prophylaxis to very selected circumstances and the role of LEV is marginal. Moreover, studies are generally designed to compare LEV versus phenytoin, whereas studies comparing LEV versus placebo are lacking. Further, randomized trials will be needed to better elucidate LEV utility and its neuroprotective role in the neurocritical setting.

Introduction Currently, antibiotic treatment is often a standard dosing regimen in bone and joint infections (BJI). However, it remains unknown if exposure at the target-site is adequate. The aim of this review is to gain more insight in the relationship between the target site concentration of antibiotic and the minimal inhibitory concentration to target the bacteria in bone and joint infections (BJI). Areas covered A literature search was performed by Erasmus MC Medical library. Bone, bone tissue and synovial concentration of antibiotics were covered in humans. In addition, we reported number of patients, dose, sampling method, analytical method and tissue and plasma concentrations. We used the epidemiological cutoff value (ECOFF) values of the targeted micro-organisms. If more than 3 publications were available on the antibiotic, we graphically presented ECOFFS values against reported antibiotic concentrations. Expert opinion For most antibiotics, the literature is sparse. In addition, a lot of variable and total antibiotic concentrations are published. Ciprofloxacin, cefazolin, cefuroxime, vancomycin and linezolid seem to have adequate average exposure if correlating total concentration to ECOFF, when standard dosing is used. With regard to other antibiotics, results are inconclusive. More extensive pharmacokinetic/pharmacodynamic modeling in BJI is needed.

Introduction Patients with non-metastatic castration-resistant prostate cancer (nmCRPC) are frequently poly-medicated due to age-related and androgen deprivation therapy (ADT)-derived comorbidities. In high-risk patients, androgen receptor inhibitors (ARIs) have shown to delay disease progression; however, drug–drug interactions (DDIs) with preexisting medications may impact the therapeutic effect and safety of these and of the ARIs themselves. Areas covered We review the potential comorbidity burden of nmCRPC patients on the basis of epidemiologic studies on age-related comorbidities, the impact of ADT and specific studies analyzing this topic. Using the DDIs compendia Lexicomp® and Drugs.com®, we provide a scenario of the potential DDIs between common mediations used to treat these comorbidities and the three currently available ARIs: apalutamide, enzalutamide and darolutamide. Expert opinion In high-risk nmCRPC patients to be treated with an ARI, careful multidisciplinary evaluation of potential DDIs is a fundamental component in the clinical-decision making. The lower potential for DDIs, the lower need for dose adjustment or change of current comedications and of patient monitoring, and safer introduction of new comedications. To optimize this step, an effort is still needed to determine the clinical relevance of DDIs and to harmonize their definition and classification among the different compendia.
