A comparative study of patients' preferences and sensory perceptions of three forms of inhalers among Thai asthma and COPD patients
In 9 study centers, 419 patients with asthma or COPD were randomized to receive two forms of salbutamol metered-dose-inhalers (MDIs), i.e. CFC-driven MDI, non-CFC (HFA) MDI and one salbutamol dry powder inhaler (DPI), in a multi-center, comparative, cross-over and randomized study, performed to faci...
