Disclosed are a novel benzamide derivative and pharmaceutical use thereof, and more particularly, a novel benzamide derivative having a structure of Formula 1 or pharmaceutically acceptable salts thereof, and a composition for prevention or treatment of pain or itching including the above material. The novel benzamide derivative and pharmaceutically acceptable salt thereof according to the present invention exhibit excellent pain-suppressive effect and, in particular, pain-suppressive effect in not only a neuropathic animal model but also other models such as a formalin model, and therefore, may be used in suppression of different pains such as nociceptive pain, chronic pain, etc. Further, since it was demonstrated that the present invention displays anti-pruritic efficacy even in an itching model, to which a mechanism and treatment concept established with respect to pain is applied, the present invention may also be effectively used in radical treatment of atopic dermatitis by applying the inventive product to an anti-pruritic composition in order to suppress an initial itching stage and treat symptoms thereof, thus preventing skin damage or inflammation after the scratching stage.
本发明涉及一种新的苯甲酰胺衍生物及其药物用途,更具体地说,涉及一种具有式1结构或其药学上可接受的盐的新的苯甲酰胺衍生物,以及包括上述物质的用于预防或治疗疼痛或瘙痒的组合物。本发明的新型苯甲酰胺衍生物和药学上可接受的盐在疼痛抑制方面表现出优异的效果,特别是在神经病理动物模型和其他模型(如福尔马林模型)中表现出疼痛抑制效果,因此可以用于抑制不同类型的疼痛,如伤害性疼痛、慢性疼痛等。此外,由于本发明在瘙痒模型中展示了抗瘙痒功效,应用于疼痛的机制和治疗理念,因此本发明可有效用于通过将该发明产品应用于抗瘙痒组合物以抑制初始瘙痒阶段并治疗其症状,从而预防刮擦阶段后的皮肤损伤或炎症,对于特应性皮炎的根治治疗。
