Bronchospasm induced by vanillin and lactose

A H van Assendelft. Eur J Respir Dis. 1984 Aug.

Abstract

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.
