MEINERZ, Ana Raquel Mano et al. Effects of high doses of terbinafine and itraconazole in Wistar rats. Rev. Bras. Cienc. Farm. [online]. 2007, vol.43, n.1, pp. 105-109. ISSN 1516-9332. http://dx.doi.org/10.1590/S1516-93322007000100013.
Taking into account the importance of the itraconazole and terbinafine in the antifungal therapy, the study has as objective evaluate the effects of high itraconazole doses (100 mg/kg) and terbinafine (250 mg/kg) in rats albino Wistar through the analyses of the hepatic enzymes (ALT and ALP), complete blood count and histopathologic study of different organs. The drugs were administered orally once a day, for a period of 30 days, when blood was collected and accomplished the necropsy of the experimental animals. The detected values of the hepatic enzymes and of the blood count were compatible to the physiologic indexes for the studied species with no statistical differences among the experimental groups. The histopathologic exam did not reveal any abnormality, however 25% of the treated with terbinafine died immediately after the administration of the drug. With those results we concluded that the administered doses of the drugs did not alter the appraised hepatic enzymes, as well as the blood count. However, more studies are needed to consider high doses of the terbinafine and itraconazole as viable treatment alternative for systemic mycosis.
