香兰素和乳糖诱发的支气管痉挛。

Eur J Respir Dis. 1984 Aug;65(6):468-72.

Bronchospasm caused by vanillin and lactose was detected in controlled double-blind challenge tests in an asthmatic patient. It is recommended that all flavouring agents and dyes should be removed from drugs. Lactose is not a suitable placebo for challenges in asthmatic patients. A better choice is cellulose, which is not resorbed by man.

在一名哮喘患者的对照双盲激发试验中检测到了由香草醛和乳糖引起的支气管痉挛。建议从药物中去除所有调味剂和染料。乳糖不是哮喘患者激发试验的合适安慰剂。更好的选择是纤维素，人体不会吸收纤维素。
