RT Journal Article SR Electronic T1 COMBINED ACTION OF CARDIOTOXIC DRUGS: A STUDY ON THE ACUTE TOXICITY OF COMBINED QUINIDINE, MEPERIDINE, PENTOBARBITAL, PROCAINE AND PROCAINE AMIDE JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 138 OP 143 VO 102 IS 2 A1 Calesnick, B. A1 Smith, N. H. A1 Beutner, R. YR 1951 UL http://jpet.aspetjournals.org/content/102/2/138.abstract AB We have demonstrated synergism of acute toxicity when quinidine, meperidine and procaine were used in combination. The possible mode of action has been explored and the potential hazard of cardiotoxicity discussed especially when pentobarbital is also used.
