Evaluation of dose linearity in the systemic availability and pharmacokinetics of topically administered diclofenac: A 14C-microdosing study in healthy volunteers.
Drug Metabolism and Disposition July 1, 2025 Severin Mairinger, Mihye Kwon, Martin Bauer et al.
An important safety consideration for topically administered drugs is the extent of systemic exposure they achieve. The aim of this study was to evaluate whether a topically administered microdose of the model drug diclofenac can predict the systemic availability, plasma, and tissue pharmacokinetics of a topical therapeutic dose. Eight healthy participants (6 men and 2 women) participated in a...
