Abstract

In our study, we examined anti-ulcerogen and antioxidant effects of dantrolene sodium on ethanol-induced gastric lesions in rats. Dantrolene sodium was administered intraperitoneally (i.p.) in several doses, and famotidine was used at a dose of 20 mg kg −1. It was found that pretreatment with dantrolene sodium at doses of 1, 5 and 10 mg kg−1 significantly reduced ethanol-induced gastric damage and malondialdehyde levels, and significantly increased antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities. We conclude that dantrolene sodium clearly has antioxidant properties and that the protective effect of dantrolene sodium against ethanol-induced gastric mucosal lesion, at least in part, depends upon the reduction in the lipid peroxidation and an increase in the activity of antioxidant enzymes SOD and GSH-Px.

      The decrease in catalase activity can be attributed to the excessive generation of these radicals, which leads to a high consumption of this enzyme to scavenge them. The depletion of glutathione levels after an acute administration of ethanol is in accordance with previous works (Büyükokuroğlu et al., 2002; Almasaudi et al., 2016) and is probably due an increase in the formation of lipid peroxides, favoring the consumption of GSH and its oxidation to GSSG by glutathione peroxidase (Yoshikawa et al., 1997). Allantoin pretreatment prevented the depletion of GSH and restored the catalase activity.

      These results indicate good stability during the analytical procedure, which would satisfy the requirements of the pharmacokinetic study. The developed UPLC/MS/MS method was successfully used for the pharmacokinetic study of Da in rat whole blood samples [27–29]. The mean blood concentration-time curves of pure Da and Da-HP-β-CD inclusion complex are shown in Fig. 7, and the mean pharmacokinetic parameters are listed in Table 3.

      The efficacy of dantrolene in treating inflammatory and anti-nociceptive disorders mediated by cytokines [19] and by arachidonic acid metabolites [11,15] has already been demonstrated. It was also proven that its antioxidant properties prevent lipid peroxidation and protect cells against the toxic effects of oxygen free radicals [9,10,41]. Furthermore, the action of this drug on the relaxation of the EUS has been previously reported and, considering that voiding is one of the natural protective mechanisms of the urinary system, it is possible that the action of dantrolene on the sphincter has major roles in this process [17,20,32].
