Special Issue Information
Dear Colleagues,
Pharmacokinetics comprises the dynamic processes of absorption, distribution, metabolism, and excretion. In drug development, metabolism assays are essential to predict drug elimination and drug–drug interactions and to understand pharmacokinetic variability related to genetic polymorphisms. The comprehension of the metabolism of xenobiotics (drugs, toxicants, drugs of abuse) is essential in risk assessment to identify the metabolic pathways and enzymes, to estimate the exposure level in the body, to predict efficacy and safety outcomes, and ultimately to support decision-making related to both human and environmental health. The metabolism of xenobiotics can occur in successive steps with the participation of several enzymes classically divided into phase I and phase II metabolism. Phase I metabolism comprises oxidation, reduction, and hydrolysis reactions mediated primarily by cytochrome P450 (CYP450) enzymes. These enzymes are predominantly found in the smooth endoplasmic reticulum of hepatocytes, although they may also be present in other tissues, such as the lung, kidney, gastrointestinal tract, nasal mucosa, skin and brain. Variability in drug metabolism can be explained by genetic variation, diseases, age-related functions and extrinsic factors (diet, alcohol, drugs) resulting in drug-induced toxicity or even the failure in pharmacological treatment. This special collection aims to bring together several aspects related to the metabolism of xenobiotics by CYP450 enzymes from in vitro, in vivo and modeling and simulation studies. Determination of enzymatic parameters, inhibition and phenotyping studies, pharmacokinetics and pharmacometrics approaches, such as PBPK modeling, are welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pharmaceuticals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
