Item Beta blockade and anticonvulsant activity of propranolol.(1978-07-01) Iyer, K S; Thampuran, R VRacemic and dextro forms of propranolol were equipotent in their anticonvulsant activity in normal rats by the MES test. In an attempt to determine any difference in the anticonvulsant activity of the two forms a variety of adrenergic agents were used, viz. phenoxybenzamine, reserpine, alphamethyl dopa and acetazolamide. There was no difference between the two forms, in the absence or presence of several adrenergic drugs employed. However, racemic but not dextro propranolol reduced MET, in normal as well as in nialamide primed rats.Item Interactions between reserpine and anticonvulsants on convulsion parameters.(1978-10-01) Iyer, K S; Thampuran, R VReserpine lowered the MET and this lowering of MET was antagonized by chloridaze-poxide but not by acetazoleamide and phenytoin. With increasing doses of reserpine the extension time in an MES test was increased and this was antagonized by all anticonvulsants tested namely acetazolamide, chlordiazepoxide, phenytoin and propranolol. High doses of reserpine abolished flexion component and this was restored by propranolol, phenytoin, atropine, chlordiazepoxide and acetazolamide.
