Vitamin B combination reduces fluconazole toxicity in Wistar rats.

BACKGROUND: The major adverse effect associated with systemic administration of Fluconazole (FLZ), is hepatic toxicity. FLZ is most commonly used antifungal drug in treatment of invasive fungal infections.

METHODS: FLZ toxicity was challenged by individual and in combination of three vitamins (B1, B2 B3). Animals were divided nine groups with six animals in each group. FLZ, at a dose of 50 mg/kg b.w, was orally administered for 90 days in experimental animals. Vitamins as individual or in combination was administered concomitantly to challenge or alleviate the toxicity of FLZ. They were sacrificed at the end of protocol for biochemical and histopathology analysis. Focus was made to observe the role of these micro nutrient's (vitamins) on liver for alteration in of pathological and physiological effects by FLZ in the Wistar albino rats.

RESULTS: Combination of vitamin B1 + B2 + B3 in FLZ induced toxicity was able to restore the level of alkaline phosphatase (ALP) near to normal but with high level of ALP in B1 Control group. Aspartate aminotransferase (AST) was restored to normal in FLZ + B1, FLZ + B2 and FLZ + B1 + B2 + B3 groups and vice versa in FLZ + B3 group animals. Further the level of alanine aminotransferase (ALT) was restored to normal in FLZ + B3 animals. There were no significant changes found in total bilirubin (TBI), and direct bilirubin (DBI) as compare to normal control. Histopathological studies on animals' studies validated the serological results in normalizing the cellular architecture of liver.

CONCLUSIONS: Restoration of altered biochemical parameters and cellular architecture of hepatocytes by different combination of these vitamins proves the chemo preventive potential of these micro nutrients' in FLZ toxicity. Graphical abstract Vitamin B combination attenuates fluconazole toxicity.
