TY - JOUR T1 - THE ACTION OF COCAINE ON THE INTESTINE JF - Journal of Pharmacology and Experimental Therapeutics JO - J Pharmacol Exp Ther SP - 209 LP - 214 VL - 49 IS - 2 AU - FREDERICK BERNHEIM Y1 - 1933/10/01 UR - http://jpet.aspetjournals.org/content/49/2/209.abstract N2 - 1. Cocaine in concentrations of 0.1 to 0.2 per cent causes relaxation of the guinea pig ileum contracted by histamin or pilocarpine. The extent of the relaxation is a function of the amount of cocaine added and the amount of histamin or pilocarpine. 2. Cocaine causes relaxation of the ileum after contraction by barium. 3. The action of nicotine and cocaine is additive. 4. It is concluded that cocaine like nicotine and atropine acts both on smooth muscle directly and on the parasympathetic endings. ER -
