Randomized Controlled Trial Multicenter Study Comparative StudyThe efficacy of tiotropium administered via Respimat Soft Mist Inhaler or HandiHaler in COPD patients.
Tiotropium, a once daily inhaled anticholinergic delivered via HandiHaler, provides bronchodilation for >24h and improves patient-centred outcomes. The Respimat Soft Mist Inhaler (SMI), a novel, propellant-free inhaler, has been developed and proposed as an alternative delivery device for use with tiotropium. ⋯ Tiotropium 5 microg Respimat SMI is comparable with tiotropium 18 microg HandiHaler in terms of efficacy, pharmacokinetics and safety. Respimat SMI is an effective alternative, multi-dose delivery device for tiotropium.

Randomized Controlled Trial Comparative StudyLung function and asthma control with beclomethasone and formoterol in a single inhaler.
Lung deposition is crucial for asthma treatment. However, there is no study comparing the potential role of lung co-deposition of combination therapy (inhaled corticosteroid and long-acting beta2 agonist) in the same inhaler. In moderate to severe asthmatics, an extra-fine hydrofluoroalkane combination of beclomethasone dipropionate and formoterol given via a single pressurised metered-dose inhaler (pMDI) was compared with beclomethasone dipropionate chlorofluorocarbon (CFC) pMDI and formoterol dry powder inhaler (DPI) given via separate inhalers. ⋯ In patients with moderate to severe asthma, beclomethasone dipropionate/formoterol in a single inhaler was as effective as beclomethasone dipropionate plus formoterol and superior to beclomethasone dipropionate alone in improving lung function. For the first time with a single inhaler, beclomethasone dipropionate/formoterol was significantly superior to separate components for asthma control.
