In vitro Evaluation of Antifungal Activity of Terbinafine Nano Form against Yeast Organism Isolated in Thumby Labs Ajman

Abstract

The goal of this study is to evaluate the antifungal activity of terbinafine in its nano form against yeast organisms in vitro and compare its effectiveness to the normal form of terbinafine. Thirty isolated yeast organisms from Thumbay Labs were included in the study. Terbinafine was serially diluted to concentrations of 50 mg, 25 mg, 12 mg, and 6 mg for both the nano and normal forms. After preparing the serial dilutions, fungal suspensions were exposed to these dilutions for 7 minutes. The suspensions were then cultured on Sabouraud dextrose agar and incubated at 37°C overnight. Growth was measured using a colony count. The results for the normal form of terbinafine revealed growth at all concentrations, with varying colony counts with a highest growth was observed at the 6 mg concentration. In contrast, the nano form of terbinafine exhibited distinct development patterns. At the 50 mg concentration, seven samples showed no growth; at the 25 mg concentration, two samples showed no growth; and the remaining samples exhibited limited growth compared to the normal form. According to the results of this study, there were significant differences in the number of colonies between the two forms of terbinafine, with the nano form demonstrating greater efficacy. The most potent antifungal response was observed at the 50 mg concentration of nano terbinafine, which inhibited yeast growth in several samples. In conclusion, terbinafine nanoemulsions are more effective than the normal form against Candida.
