The impact of gene polymorphisms on the response of methotrexate-based treatments. (PubMed, Eur J Clin Pharmacol)
Although considerable research has been conducted and numerous results have been obtained, the available evidence remains predominantly of moderate quality. Consequently, current guidelines from CPIC and the DPWG do not recommend routine MTX dose adjustments based solely on single gene variants. It is, therefore, imperative to develop and validate multifactorial risk prediction tools that integrate a range of other clinical factors. Accordingly, the establishment of a comprehensive pharmacogenetics-guided dosing guideline for MTX remains an elusive goal.
