  • Acrivastine (BW825C) 是用于治疗过敏性鼻炎的短效histamine 1受体拮抗剂。
  • 阿伐斯汀是一种中等强度的竞争性组织胺H1受休拮抗剂,属于抗组胺药,20世纪80年代末由葛兰素威康公司推出的酚嗪类抗组胺类抗过敏药物,具有选择性地阻断组胺H1受体的作用,没有明显抗胆碱作用。对中枢神经系统的穿透能力低,可通过完全或部分阻止组织胺释放而缓解由其引起的症状。不易通过血脑屏障,无镇静作用。口服吸收良好,1.5小时达血药峰浓度,大部分原形药物经肾排泄,少部分经肝代谢,代谢产物仍具活性,由尿排出。适用于治疗过敏性鼻炎、枯草热、荨麻疹、湿疹、皮肤瘙痒症等。

体内研究 Acrivastine(通常每天3次,每次8mg)是治疗慢性荨麻疹和过敏性鼻炎的有效且耐受良好的抗组胺药。在治疗季节性过敏性鼻炎中,阿伐他汀比安慰剂更有效,并且对氯马斯汀或特非那定的疗效相似。在治疗其中组胺具有致病作用的皮肤病中,阿克他那的功效优于安慰剂,并且类似于常用剂量的氯马斯汀,羟嗪,氯苯那敏,赛庚啶或特非那定。 Acrivastine引起的睡眠不如clemastine,不良反应的发生率与安慰剂或特非那定无法区分[1]。 4 mg和8 mg acrivastine均可减轻季节性过敏性鼻炎的症状,并显着改善打喷嚏,流鼻涕的症状评分和计算的总体评分。此外,8毫克acrivastine可减轻水汪汪的眼睛和喉咙发痒的症状评分。 Acrivastine对季节性过敏性鼻炎的治疗耐受性良好且有效[2]。
