The main purpose of the invention is to provide a novel pyridine derivative or a pharmaceutically acceptable salt thereof. Examples of the invention include a pyridine derivative represented by general formula [1], and a pharmaceutically acceptable salt thereof. This compound or a pharmaceutically acceptable salt thereof exhibits mGluR5 inhibitory activity, and can therefore be used as an agent for the prevention or treatment of, e.g., pain (for example, acute pain, chronic pain, inflammatory pain, neuropathic pain, hyperalgesia, thermal hyperalgesia, allodynia, pain due to noxious thermal stimulation, pain due to noxious mechanical stimulation, pain in the lower urinary tract or reproductive organs, or migraine), pruritus, lower urinary tract symptoms or lower urinary tract dysfunctions, gastroesophageal reflux disease (GERD), gastroesophageal reflux associated with transient lower esophageal sphincter relaxation (TLESR), and diseases of the central nervous system.
本发明的主要目的是提供一种新型吡啶衍生物或其药学上可接受的盐。本发明的例子包括由通式[1]表示的吡啶衍生物及其药学上可接受的盐。该化合物或其药学上可接受的盐表现出mGluR5抑制活性,因此可用作预防或治疗疼痛(例如急性疼痛、慢性疼痛、炎症性疼痛、神经病理性疼痛、过敏性疼痛、热性过敏、触觉过敏、因有害热刺激引起的疼痛、因有害机械刺激引起的疼痛、下尿路或生殖器官的疼痛或偏头痛),瘙痒、下尿路症状或下尿路功能障碍、胃食管反流病(GERD)、胃食管反流伴随瞬时下食管括约肌松弛(TLESR)以及中枢神经系统疾病的药剂。
