Title: Multinational, Double Blind, Randomised, Parallel Group Study on the Therapeutic Efficacy and Safety of Beclomethasone Dipropionate 250 mg Combined With Salbutamol 100 mg in the Treatment of Patients With Mild Persistent Asthma.
Brief Summary: The aim of this study is to reveal that inhaled corticosteroid therapy combined with a short-acting beta2- agonist given on a symptom driven basis is as effective as traditional asthma therapy.

Thus, three advantages will be achieved:

1. better compliance with treatment since patients will most likely have to administer the treatment less frequently,
2. maximum pharmacological effect with the least amount of drug and
3. less economic burden on health care providers.
