We aim to develop an efficient and non-invasive strategy for monitoring of drugs and their metabolites via human skin. Probe sampling was combined with thermal desorption-electrospray ionization tandem mass spectrometry (TD-ESI/MS/MS) to characterize trace terbinafine, which was secreted on patient's skin after ingesting terbinafine tablets. The terbinafine ion signals were directly detected in the samples collected from different skin regions and the signals were monitored for 8 weeks. The detection and location of terbinafine via the skin suggest that the methods are useful in rapidly and noninvasively collecting the molecular information of the ingested drug on skin for pharmacokinetic studies.

Background: Microsporum canis, a dermatophyte commonly associated with pets, is a leading cause of severe tinea capitis. The increasing prevalence of antifungal resistance among dermatophytes poses a significant global health challenge.
Objectives: This study aims to define the updated antifungal susceptibility profile of M.

species, the leading cause of dermatophytosis globally, are increasingly resistant to antifungal treatments, concerns about effective management strategies. In light of the absence of established resistance criteria for terbinafine and azoles, coupled with a dearth of research on resistance mechanisms in , antifungal susceptibility and drug resistance gene diversity were analyzed across 64 , 65 , and 2 isolates collected in China between 2001 and 2024 and 101 published strains. Analyses of the minimum inhibitory concentrations (MICs) of terbinafine, itraconazole, voriconazole, posaconazole, and isavuconazole revealed a concerning increase in with terbinafine resistance, including two novel isolates from China.

Background: Since 2017, dermatophytosis caused by the newly introduced species Trichophyton indotineae has gained new interest worldwide due to the rise in terbinafine resistance and difficulty in the treatment of recalcitrant infections. Distinguishing T. indotineae from other Trichophyton species based on morphological features is impossible and DNA sequencing is necessary for accurate identification.

Poloxamer 407 is a versatile excipient that enhances drug solubilization and prolongs drug release. Poloxamers are non-ionic tri-block copolymers composed of a central hydrophobic chain of polyoxypropylene flanked by two hydrophilic chains of polyoxyethylene. Various researchers have utilized Poloxamer 407 in topical and transdermal drug delivery systems, and it has also been reported to enhance skin permeability.
