Effects of CGS 9896 in acute experimental intoxication with fluostigmine.

The therapeutic effectiveness of CGS 9896, a novel potent anxiolytic and anticonvulsant, in organophosphate intoxication was studied. It was demonstrated that this drug, used as an adjunct to a mixture of atropine and obidoxime, led to a rise in the LD50 of fluostigmine in mice of more than 150 times and more than 138 times for 2 and 24 h, respectively. After 24 h, this effect was twice that of diazepam, which served as a reference drug.
