Scientists at the University of Manchester’s North West Lung Centre have found that codeine - a standard ingredient in cough remedies – could be no more effective than an inactive placebo compound at treating cough.
Researchers at the Centre, which is based at Wythenshawe Hospital, studied a sample of patients with chronic lung disease. After coughing was induced with citric acid they were given either codeine or a placebo, and sent home wearing a lapel microphone to record their coughing during the day and night.
Lead researcher Dr. Jacyln Smith said: “Codeine has long been considered the standard anti-cough agent against which others are measured, but until now little has been known about its impact in patients with chronic lung diseases.
