DISSOCIATION OF ANALGESIC, RESPIRATORY AND EMETIC EFFECTS JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 218 OP 221 VO 130 IS 2 A1 Keats, Arthur S. A1 Telford, Jane A1 Kurosu, Yoshio YR 1960 UL http://jpet.aspetjournals.org/content/130/2/218.abstract AB The analgesic, respiratory and subjective effects of 4-acetoxy-3-methyl-1-(phenylethyl)-4-0-tolylpiperidine hyrochloride have been studied in man. This compound has demonstrated a remarkable quantitative dissociation in the analgesic, respiratory and emetic activities considered to be obligatory side actions of potent analgesics. In doses which produce analgesia equivalent to morphine, this compound produced severe respiratory depression, minimal nausea and no vomiting. The significance of the demonstration of this dissociation has been discussed.
