Randomized Controlled Trial Comparative StudyA randomized study of tiotropium Respimat Soft Mist inhaler vs. ipratropium pMDI in COPD.
The aim of these studies was to compare the efficacy and the safety of tiotropium, delivered via Respimat Soft Mist Inhaler (SMI), a novel multi-dose, propellant-free inhaler, with ipratropium pressurized metered-dose inhaler (pMDI) in chronic obstructive pulmonary disease (COPD) patients. Two identical, 12-week, multi-national, randomized, double-blind, double-dummy, parallel-group, active- and placebo-controlled studies were performed. COPD patients were randomized to treatment with either inhaled tiotropium (5 or 10 microg) via Respimat SMI administered once daily, ipratropium (36 microg) pMDI QID or placebo. ⋯ All active treatments significantly reduced the rescue medication use compared with placebo, but only tiotropium 10 microg was statistically superior to ipratropium (P=0.04). The incidence of adverse events was comparable across groups. In conclusion, tiotropium 5 and 10 microg daily, delivered via Respimat SMI, significantly improved lung function compared with ipratropium pMDI and placebo.

Randomized Controlled Trial Comparative StudyEarly administration of two intravenous bolus of aminophylline added to the standard treatment of children with acute asthma.
Evaluate the efficacy of adding two intravenous bolus of aminophylline to the standard treatment of acute asthma episode in children admitted to the pediatric emergency room (PER). ⋯ In children aged 2-5 years admitted to a PER with asthma, two intravenous doses of 5mg/kg of aminophylline given 6h apart did not change the length of stay in hospital, the number of nebulizations given or the duration of oxygen therapy required. We are unable to tell whether there would be benefit with higher doses of aminophylline designed to give levels in the usual therapeutic range.
