                            A therapeutic composition is provided that comprises a 1-R1-phenyl, 4-R2-phenyl substituted 1,2,3,6-tetrahydropyrimidine-2-one cold receptor agonist in a therapeutically effective amount and preferably further comprises one or more pharmaceutically active drugs such as an anti-inflammatory glucocorticosteroid, a sympathomimetic amine decongestant, an anti-histamine, a local anesthetic, menthol or a menthol analog, and mixtures thereof. The cold receptor agonist may be represented by the general formula 1-[1R-phenyl]-4-[R2-phenyl]-1,2,3,6-tetrahydropyrimidine-2-one wherein: R1 is -hydroxy, -chloro, -fluoro, -alkyl, -acetoxy, -trifluoromethyl; and R2 is -nitro, -chloro, -fluoro, -alkyl, -trifluoromethyl. Therapeutic compositions of the invention elicit long-lasting cooling or soothing, particularly when formulated for delivery to suppress the sensations of itch and pain, such as for delivery to inflamed skin, to the mucous membranes of the anogenital areas, and to the enteric mucosa.
                            本发明提供了一种治疗组合物,该组合物包含治疗有效量的 1-R1-苯基、4-R2-苯基取代的 1,2,3,6-四氢
嘧啶-2-酮冷受体激动剂,并优选进一步包含一种或多种药学活性药物,如抗炎性糖皮质激素、拟交感
胺类减充血剂、
抗组胺药、局麻药、薄荷醇或薄荷
醇类似物及其混合物。冷受体激动剂可由通式 1-[1R-苯基]-4-[R2-苯基]-1,2,3,6-四氢
嘧啶-2-酮表示,其中:R1为-羟基、-
氯、-
氟、-烷基、-乙酰氧基、-三
氟甲基;R2为-硝基、-
氯、-
氟、-烷基、-三
氟甲基。本发明的治疗组合物能产生持久的冷却或舒缓作用,特别是在配制成给药剂以抑制痒和痛的感觉时,如给发炎的皮肤、肛门生殖器部位的粘膜和肠道粘膜。
