Migraine is a brain disease whose principal symptom is episodic intense throbbing pain in the head which is often accompanied by photophobia, phonophobia, nausea and vomiting. Primary objectives of migraine treatment are to abort the acute attacks, treat associated symptoms and prevent future attacks. With a majority of migraine patients being young, they will need a treatment plan to suit their professional work, leisure and reproductive concerns. Non specific anti-migraine drugs like non-steroidal anti-inflammatory drugs, anti-emetics, narcotics, and sympathomimetics are usually helpful in mild to moderate attacks. Specific drugs like triptans and ergots are useful for moderate to severe attacks. In step care approach, the patients are started with the simplest options like simple analgesics first followed by non-steroidal agents, then ergot preparations and eventually triptans if they do not respond. In stratified care approach, the attacks and the patients are stratified according to the severity and therapeutic response. Those with severe disabling episodes are given specific anti-migraine medications like triptans whereas patients with mild or low disability are treated with simple analgesics. Currently, the most favored acute anti-migraine medication is a triptan. At marketed doses all triptans are effective as compared to placebos and generally well tolerated. Amongst them however, rizatriptan 10 mg, eletriptan 80 mg and almotriptan 12.5 mg provide the highest likelihood of consistent success. Triptan related adverse events are usually short lived, mild and clinically insignificant. Ergots are slowly being replaced by triptans. This is because of their adverse side-effects, low bioavailability and high potential for abuse that can lead to overuse headache.
偏头痛是一种脑部疾病,其主要症状是头部阵发性剧烈搏动性疼痛,常伴有畏光、畏声、恶心和呕吐。偏头痛治疗的主要目标是终止急性发作、治疗相关症状并预防未来发作。由于大多数偏头痛患者为年轻人,他们需要一个适合其职业工作、休闲和生育需求的治疗方案。非特异性抗偏头痛药物,如非甾体抗炎药、止吐药、麻醉药和拟交感神经药,通常对轻至中度发作有帮助。特异性药物,如曲坦类药物和麦角生物碱,对中至重度发作有用。在阶梯治疗方法中,患者首先从最简单的选择开始,如简单镇痛药,然后是非甾体类药物,再是麦角制剂,如果无效最终使用曲坦类药物。在分层治疗方法中,根据发作的严重程度和治疗反应对发作和患者进行分层。那些有严重致残性发作的患者给予特异性抗偏头痛药物,如曲坦类药物,而轻度或低致残性患者则用简单镇痛药治疗。目前,最受欢迎的急性抗偏头痛药物是曲坦类药物。在上市剂量下,与安慰剂相比,所有曲坦类药物均有效,且一般耐受性良好。然而,其中10毫克利扎曲普坦、80毫克依立曲坦和12.5毫克阿莫曲坦获得持续成功的可能性最高。曲坦类药物相关的不良事件通常持续时间短、症状轻微且临床意义不大。麦角生物碱正逐渐被曲坦类药物所取代。这是因为它们的副作用、低生物利用度以及高滥用潜力,可能导致药物过量使用性头痛。
