Comparative study of the effect of atropine, P2AM, and Buscopan. Total belladonna and hyoscyamus alkaloids on parathion poisoning.

Among the available antidotes used against parathion poisoning, atropine and Buscopan are tolerated in relatively high doses by rats. Hyoscine (in very small doses), T. Bel. Alk. and T. Hyosc. Alk. (better results in small doses, also for dogs), P2AM (of superior antimuscarine action) are redommended with each of the preceding drugs than either alone or in combination with Buscopan.
