The effects of subcutaneous administration of the non-peptide NK-1 (substance P) receptor antagonist, CP-96,345, and its stereoisomer, CP-96,344, were tested in three nociceptive paradigms in the rat. In the first paradigm, tail flick responses were monitored before and after intrathecal administration of substance P (6.5 nmol) in rats pretreated subcutaneously with saline, CP-96,344 (5 mg/kg) or CP-96,345 (5 mg/kg). In the control groups, pretreated with saline (n = 6) or with CP-96,344 (n = 5), substance P reduced the tail flick reaction time at 1 min after administration to 38.3 +/- 5.1 (mean +/- S.E.M.) and 32.1 +/- 7.7% of the mean baseline value, respectively. In contrast, in the group pretreated with CP-96,345 (n = 6) the reaction time following administration of substance P was 98.8 +/- 3.3% of the baseline reaction time; this value was not significantly different from the baseline value of this group, indicating a block (P < 0.01) of the substance P-induced facilitation of the tail flick response. In the second paradigm, rats were anesthetized with a mixture of chloral hydrate (120 mg/kg, i.p.) and sodium pentobarbital (20 mg/kg, i.p.), and the effects were determined on tail flick reaction time of a sustained noxious cutaneous stimulation, immersing the tip of the tail in hot water at 55 degrees C. In the groups of rats pretreated with saline (n = 4) or with CP-96,344 (n = 7), this noxious stimulus produced a transient decrease in reaction time to 62-74% of the baseline value.(ABSTRACT TRUNCATED AT 250 WORDS)
