Evaluation of the combination inhaler of salbutamol and beclomethasone dipropionate in the management of asthma.

An open parallel study lasting 24 weeks was performed in 39 asthmatics to evaluate patient compliance and the clinical effects of regular inhalations of beclomethasone dipropionate and salbutamol used simultaneously from a combination inhaler with regular inhalations of salbutamol and beclomethasone dipropionate used sequentially from separate inhalers. Total daily doses in the two groups were 800 micrograms salbutamol and 400 micrograms beclomethasone dipropionate. There were no differences between the two treatment groups with respect to clinic pulmonary function tests (FEV1, FVC), daily PEF measurements, symptom scores, use of symptomatic bronchodilator therapy, requirements for extra medication and patients' and physician's assessment of treatment. At 12 weeks, the physician assessed significantly more patients to have better symptom control on the combination inhaler than on separate inhalers. Patient compliance was high in both treatment groups which may have been due to the close supervision of the clinical study.
