Bemegride lengthens seizure duration during electric convulsive therapy in a schizophrenic patient with increased seizure threshold.

A 48-year-old man who had a history of schizophrenia for 30 years was treated with electroconvulsive therapies. Because of poor seizure even at maximum electrical dosage, aminophylline was administered just before initiating electroconvulsive therapy. Although aminophylline augmentation lengthened the seizure duration, tachycardia and hypertension were observed. Therefore, we switched to bemegride, an antagonist to barbiturate, and seizure length was improved without any side effects. The present case suggested that bemegride is one of the alternative measures in patients with poor seizure quality.

Pharmacological studies on a new dihydrothienopyridine calcium antagonist, S-312-d. 5th communication: anticonvulsant effects in mice.

S-312, S-312-d, but not S-312-l, L-type calcium channel antagonists, showed anticonvulsant effects on the audiogenic tonic convulsions in DBA/2 mice; and their ED50 values were 18.4 (12.8-27.1) mg/kg, p.o. and 15.0 (10.2-23.7) mg/kg, p.o., respectively, while that of flunarizine was 34.0 (26.0-44.8) mg/kg, p.o. Although moderate anticonvulsant effects of S-312-d in higher doses were observed against the clonic convulsions induced by pentylenetetrazole (85 mg/kg, s.c.) or bemegride (40 mg/kg, s.c.), no effects were observed in convulsions induced by N-methyl-D-aspartate, picrotoxin, or electroshock in Slc:ddY mice. S-312-d may be useful in the therapy of certain types of human epilepsy.

[Monoamine content of the blood in the experimental pharmacotherapy of alcoholic intoxication]. / Soderzhanie monoaminov v krovi pri éksperimental'noi farmakoterapii alkogol'noi intoksikatsii.

Experiments on rabbits have shown that caffeine (10 mg/kg), ethimizol (10 mg/kg) and particularly bemegride (5 mg/kg) increase the blood adrenaline and noradrenaline content up to the level characteristic for intact animals under acute ethanol poisoning (2.5 g/kg per os). This effect has been found to be more remarkable on repeated administration. The shifts in the serotonin content are inconsistent in this case.

[Metabolic shifts during the repeated administration of analeptics in alcoholic intoxication]. / Metabolicheskie sdvigi pri povtornom vvedenii analeptikov v usloviiakh alkogol'noi intoksikatsii.

It was shown in experiments on rabbits that under acute alcohol poisoning of medium degree, repeated administration of caffeine (10 mg/kg) and bemegrid in particular (5 mg/kg) promotes aerobization of the oxidative processes and mobilizes the respiratory mechanism of metabolic acidosis compensation. Under these conditions, ethimizol (10 mg/kg) stimulates the respiratory center and promotes (to a less measure) aerobization of the metabolic processes in tissues and ethanol elimination.
