Abstract:
:The effects of methaqualone on isonicotinic acid hydrazide, 6-mercapto propionic acid, picrotoxin, and strychnine-induced convulsion were studied in mice and the results compared with diazepam. Methaqualone, like diazepam, was found to be a selective antagonist of isoniazid-induced convulsion and a much less effective inhibitor of strychnine convulsion. Methaqualone elicits muscle-relaxant, sedative, and anticonvulsant effects at different dose levels. At low, nonsedative doses the drug produces anticonvulsant effects, and at higher doses, muscle-relaxant and sedative effects. It appears that the mechanism(s) of action of methaqualone in on GABA deficiency or receptor blockade, rather than on glycine receptors.
