COMPARISON OF THE ACCEPTABILITY OF THE VENTOLIN METERED-DOSE INHALER AND THE BRICANYL TURBUHALER

One hundred fifty-nine asthmatic patients aged 19 to 76 years completed an open crossover-designed study comparing the acceptability of the Bricanyl Turbuhaler (BTH) and the Ventolin metered-dose inhaler (VMDI). The doses given were presumed to be equiactive. Each treatment period lasted for 14 days. Patients registered morning and evening peak expiratory flow rate (PEFR) before and five minutes after medication. Asthma symptoms as well as adverse events were registered on diary cards. After each study period a questionnaire containing acceptability questions was completed. At the end of the study the patients indicated their preference for one of the two treatments. The two treatments were equal concerning bronchodilation and asthma symptoms. There was an overall preference for the Bricanyl Turbuhaler.
