Brief Summary:
To compare the bronchodilator efficacy of ipratropium plus salbutamol (Combivent) with salbutamol alone given every 20 minutes for three doses in asthmatic children with severe acute exacerbation

Condition or disease Intervention/treatment Phase
Asthma Drug: ipratropium plus salbutamol UDV Drug: salbutamol UDV Phase 4

Detailed Description:

A Comparison of Ipratropium 500mcg and salbutamol 2.5mg (Combivent UDV) and salbutamol UDV alone (2.5mg) in a Double-blind, Efficacy and Safety Study in Asthmatic Children with Severe Acute Exacerbation

Study Hypothesis:

Several studies, including a study conducted in an emergency room setting, demonstrated that the addition of ipratropium bromide, an anticholinergic drug, to standard salbutamol therapy significantly improves pulmonary function as compared to salbutamol alone.


Ipratropium bromide 500 mcg plus salbutamol 2.5mg (Combivent) vs salbutamol (2.5mg) alone given every 20 minutes for 3 doses
