Bicifadine [DOV 220,075; (+/-)-1-(4-methylphenyl)-3-azabicyclo-[3.1.0]hexane HCl)] is a non-narcotic analgesic that has proven to be effective for the treatment of acute pain in clinical studies. The pharmacokinetics, disposition, and metabolism of bicifadine were determined in eight healthy adult male subjects following a single oral dose of 200 mg of [(14)C]bicifadine in solution. The maximum concentration of total drug equivalents and bicifadine in plasma was at approximately 1 h; the elimination half-life was 2.6 and 1.6 h for radioactivity and bicifadine, respectively. Unchanged bicifadine represented 15% of the area under the concentration-time curve for total drug equivalents; the rest was due mainly to the lactam (M12), the acid (M3), and the lactam acid (M9). Total recovery of the dose was 92%, with most of the radioactivity recovered in the urine in the first 24 h; fecal excretion accounted for only 3.5% of the dose. Approximately 64% of the dose was metabolized to M9 and its acyl glucuronide; another 23% was recovered as M3 and its acyl glucuronide. Neither bicifadine nor M12 were detected in urine or feces. There were no reported serious or severe adverse events during the study.

Phencyclidine (1-(1-phenylcyclohexyl)piperidine, CAS 77-10-1, PCP, I) and many of its analogues have been synthesized and their pharmacological properties studied. In this research, new methyl morpholine derivative of phencyclidine (1-[1-(4-methylphenyl) (cyclohexyl)]morpholine, Methyl-PCM, III) was synthesized and the acute and chronic pain activities were studied using tail immersion and formalin tests on rats and compared to PCP and PCM (1-(1-phenylcyclohexyl)morpholine, CAS 2201-40-3, PCP-morpholine, II). The results Indicated that Methyl-PCM (III, 6 mg/kg, i.p) produces more analgesic effects in tail immersion test (as a model of acute thermal pain) in comparison with the PCP, PCM and control groups. Meanwhile, this analgesic effect was markedly shown 5-15 min after the compound III application. In formalin test analysis, the acute pain (phase I) could not be affected by any drugs, but the chronic formalin pain (phase II) could be diminished by PCM and especially compound III. The chronic analgesic effect of Methyl-PCM was markedly shown in the late phase of chronic pain.
