title: Therapeutic effects of some cholinolytics in organophosphate intoxications.
abstract: The therapeutic effects of pipethanate (sycotrol) and two newly synthetized cholinolytics, DPX-8 and ANC-51, were compared with atropine in mice poisoned by DDVP, fluostigmine, phospholine, and paraoxon. The antagonistic activotagonistic activity of tested drugs against acetylcholine-induced contraction of rat ileum and oxotremorine-induced salivation and tremor in the mouse was also studied. The anticholinergic activity of pipethanate, DPX-8, and ANC-51 was weaker than that of atropine. However,the therapeutic effect of pipethanate was higher than that of atropine in mice poisoned by the organophosphates. DPX-8 and ANC-51 afforded a better antidotal effect than atropine only in DDVP-poisoned mice.
