Abstract

Background: Pediatric kidney transplantation requires complex multidisciplinary coordination. The contributions of pharmacotherapeutic aspects to this practice have been of fundamental importance, even in low- and middle-income countries (LMIC).

Methods: We conducted a quasi-systematic review of the PubMed and Google Scholar databases from inception to July 2024 using Medical Subject Headings and keywords relevant to Therapeutic Drug Monitoring (TDM) and Model-Based Precision Dosing (MIPD). The quality of the articles and data collected were appraised using the appropriate critical appraisal tools and was synthesized qualitatively.

Results: TDM and the analyses and interpretations associated with pharmacometric aspects, specifically clinical pharmacokinetics, have led to the use of modern strategies such as MIPD. These strategies allow for individually adjusted drug dosages to be optimized, making them more effective and safer for many immunosuppressants, antibiotics, antivirals, antifungals, antiepileptics, antineoplastics, and antiarrhythmics, among others. Several points of interest associated with improving the implementation and practice of TDM-MIPD, particularly challenging in LMICs, include the availability and adequate management of economic resources (such as software and laboratory supplies), the development of collaborative work with other institutions (including foreign ones), the possibility of consolidating independent management not depending on other clinical services, the need to train and maintain highly skilled professional staff for clinical and research purposes, and the establishment and maintenance of specialized educational programs.

Conclusion: Throughout the world, but especially in LMICs, there is a need to intensify strategies that allow for the more widespread application of TDM-MIPD to improve pharmacotherapeutic care for this highly vulnerable patient population.

Keywords: pediatrics; pharmacokinetics; pharmacology; therapeutic drug monitoring; transplantation.
