Beta-lactam antibiotics are often affected by these physiological changes, leading to variable and often subtherapeutic exposures. Therefore, methods to increase the probability of a therapeutic exposure may be beneficial for critically ill patients. Model Informed Precision Dosing (MIPD) is an emerging strategy using advanced computer models to individualise dosing in this vulnerable population with or without therapeutic drug monitoring (TDM). By tailoring therapy to the individual patient scenario, MIPD aims to improve clinical outcomes by enhancing the likelihood of effective and safe therapy.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Summary: &lt;/strong&gt;MIPD-guided beta-lactam antibiotic dosing may improve the probability of attaining target therapeutic exposures and clinical cure rates compared to standard fixed dosing in critically ill patients. Moreover, MIPD allows clinicians to target higher beta-lactam antibiotic exposures while minimising the risk of toxicity, when the goal of treatment is both improving clinical cure rates and suppressing the probability of antibiotic resistance emergence. No differences in mortality and adverse event reduction compared to standard dosing have been currently identified in the literature. However, the exact potential of MIPD has yet to be determined given the significant limitations in the current evidence base, including heterogeneous study designs, small sample sizes, inconsistent implementation strategies, and variable outcome definitions. Clinical practice and future research should optimise MIPD performance by selecting appropriate and innovative beta-lactam antibiotic exposure models, as well as identify methods to instigate early MIPD dosing and timely TDM dose adjustments. This may further improve clinical and economic outcomes for critically ill patients.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Key messages: &lt;/strong&gt;MIPD is a clinical decision making tool that uses pharmacokinetic modelling to guide beta-lactam dosing, with or without TDM input. A small number of observational and randomised beta-lactam MIPD intervention studies suggest that clinical outcomes for critically ill patients are improved. Technical, casemix, implementation, and study design limitations likely contribute to inconsistent findings in studies comparing MIPD to standard care. Stronger signals in improved outcomes are correlated with appropriate pharmacokinetic model and pharmacokinetic/pharmacodynamic (PK/PD) target selection, accompanied with timely dose adjustments in critically ill patients with significant pharmacokinetic variability and/or complex pharmacodynamic profiles.

Most cancer drugs have a narrow therapeutic index with substantial pharmacokinetics variability. Yet, current dosing approaches do not fully account for the complex pathophysiological characteristics of the patients. In this regard, the effect of sex on anticancer chemotherapeutic drugs' disposition is still underexplored. In this article, we review sex differences in chemotherapeutic drug pharmacokinetics; we suggest a novel approach that integrates sex into the traditional a priori body surface area (BSA) dosing selection model, and finally, we provide an overview of the potential benefits of a broader use of therapeutic drug monitoring (TDM) in oncology.</p><p><strong>Summary: </strong>To date, anticancer chemotherapeutic drug dosing is most often determined by BSA, a method widely used for its ease of practice, despite criticism for not accounting for individual factors, notably sex. Anatomical, physiological, and biological differences between males and females can affect pharmacokinetics, including drug metabolism and clearance. At equivalent doses, females tend to display higher circulating exposure and more organ toxicities, which has been formally demonstrated at present for about 20% of chemotherapeutic drugs. An alternative could be the sex-adjusted BSA (SABSA), incorporating a 10% increase in dosing for males and a 10% decrease for females, though this approach still lacks formal clinical validation.
