肠易激综合征 （IBS）是一种痛苦而又难以治愈的胃肠功能紊乱性疾患，临床表现为腹痛、腹胀、排便习惯和大便性状异常。这是一种持续存在或间歇发作、缺乏形态学和生化学异常改变的症候群。多见于中青年，女性约为男性的2倍。流行医学研究表明，美国有14%的成年男人和27%的成年妇女发生有IBS症状。在香港也约有13%的成年男人和21%的成年妇女有IBS症状。 IBS是普通科和肠胃专科门诊最常见病种之一。到目前为止，IBS的临床治疗，包括有多种治疗方法，如传统的化学药物、饮食调节、心理咨询等等，但是，至今尚没有十分有效以及根治的方法。鲁比前列酮、阿洛司琼、颅痛定、泻痢停等都是常用的、疗效比较显著的西方药物，.....
