NCT00920127
Obstructive airways disease is a very common condition. This condition includes patients with asthma, chronic obstructive pulmonary disease (COPD), emphysema or chronic bronchitis. Some patients with obstructive airways disease have problems with long term breathlessness, wheeze and cough with or without sputum production. Currently the researchers give treatments - usually inhalers - which are designed to open the airways and reduce the breathlessness and wheeze. Despite these available treatments many patients still have continuing symptoms. Anecdotal clinical evidence suggested that a herbal remedy (called AKL1) has beneficial effects in respiratory conditions, with patients diagnosed as having both asthma and COPD reporting reduced symptoms including breathlessness and cough and reduced frequency of attacks.The purpose of this study is to confirm whether AKL1 does indeed have a meaningful benefit to patients with obstructive airways disease. The researchers will mainly be measuring any effect of AKL by assessing any change in trial subjects' coughs, using a questionnaire, but the researchers will also looking at breathing tests, walking tests, blood and sputum tests.
