  • Title: Inhibition by antiepileptics of carbachol but not lithium- or 5-methoxytryptamine-induced wet dog shakes in rats.

    Journal: Pol J Pharmacol Pharm; 1988; 40(2):119-28. PubMed ID: 3148910.
    Abstract:
    The influence of antiepileptic drugs on the wet dog shakes (WDS) induced by intracerebroventricular injections of carbachol (30 micrograms icv) was investigated in rats. Diphenylhydantoin (DPH, 8 and 4 mg/kg), diazepam (0.4, 0.2 and 0.1 mg/kg), phenobarbital (12.5, 6.25 and 3.12 mg/kg), sodium valproate (Depakine, 200, 100 and 50 mg/kg) and trimethadione (200, 100 and 50 mg/kg) given ip inhibited the WDS in a dose-dependent manner. These drugs at the same doses did not change the intensity of shaking behavior induced by lithium chloride or 5-hydroxytryptamine. As the antiepileptic drugs tested in these experiments did not have anticholinergic activity and at used doses were not able to prevent electrical convulsions or pentetrazol-induced seizures, it appears that carbachol-induced WDS could be connected with convulsive activity and could be the initial stage of seizures.
