Abstract:
Terbinafine is an antimycotic drug usually used against several superficial fungal infections and with a potential application in the treatment of human cancers. Since to date there are few data on the genotoxic effects of terbinafine in mammalian cells, current study evaluated the potential genotoxic of such antifungal agent in cultured human peripheral blood lymphocytes. Terbinafine was used at the peak plasma concentration (1.0 μg/ml) and in four additional concentrations higher than the human plasmatic peak (5.0 μg/ml, 25.0 μg/ml, 50.0 μg/ml and 100.0 μg/ml). Chromosomal aberrations (CA), sister chromatid exchanges (SCE), micronuclei (MN), nucleoplasmic bridges (NP) and nuclear buds (NB) were scored as genetic endpoints. In all analysis no significant differences (α = 0.05, Kruskal-Wallis test) were observed. Complementary criterion adopted to obtain the final response in cytogenetic agreed with statistical results. Therefore, results of this study showed that terbinafine neither induced CA, SCE, MN, NP and NB nor affected significantly mitotic, replication and cytokinesis-block proliferation indices in any of the tested concentrations. It may be assumed that terbinafine was not genotoxic or cytotoxic to cultured human peripheral blood lymphocytes in our experimental conditions.
Insights
Terbinafine, an antifungal drug, was evaluated for genotoxic effects in human lymphocytes. The study found no evidence of genotoxicity or cytotoxicity at tested concentrations, suggesting safety for human cells.
Area of Science:
- Toxicology
- Genetics
- Pharmacology
Background:
- Terbinafine is an established antimycotic agent with emerging potential in cancer therapy.
- Limited data exists on the genotoxic effects of terbinafine in mammalian cells.
Purpose of the Study:
- To investigate the genotoxic potential of terbinafine in cultured human peripheral blood lymphocytes.
- To assess terbinafine's effects on chromosomal aberrations and other genetic endpoints.
Main Methods:
- Human peripheral blood lymphocytes were exposed to terbinafine at various concentrations, including peak plasma levels.
- Genetic endpoints analyzed included chromosomal aberrations (CA), sister chromatid exchanges (SCE), micronuclei (MN), nucleoplasmic bridges (NP), and nuclear buds (NB).
- Statistical analysis using the Kruskal-Wallis test was performed to determine significance.
Main Results:
- No significant differences were observed in CA, SCE, MN, NP, or NB frequencies at any tested concentration (p > 0.05).
- Mitotic, replication, and cytokinesis-block proliferation indices remained unaffected by terbinafine exposure.
- The results indicated no genotoxic or cytotoxic effects of terbinafine under the experimental conditions.
Conclusions:
- Terbinafine demonstrated a lack of genotoxic and cytotoxic activity in cultured human peripheral blood lymphocytes.
- These findings suggest terbinafine is safe concerning genotoxicity in human lymphocytes at the tested concentrations.
