Treatment of Asthma: The long-acting beta-2-agonists

The traditional Vienna Asthma Forum was held in early June 1996 and th was the 6 in a biennial mode within 10 years. This time it was dedicated to the long-acting beta-2-agonists, which were registered (or just about to be) in most European countries. The introduction of this therapeutic principle into routine praxis of asthma therapy was so successful that a closer view on the subject from a scientific point was warranted. Salmeterol, shortly afterwards formo- terol are the drugs available for the inhalative route, while bambuterol serves as an oral agent. The scientists particularly involved in the design and pharma- cokinetics of these drugs were invited, and we were lucky that Malcolm Johnson (Glaxo), Leif Svensson (Astra) and Gary Anderson (Ciba- Geigy) delivered fascinating contributions. However, drug therapy of this kind can only be effective if based on a thorough understanding of the molecular biology of cells and receptors, which was superbly covered by Sheila Collins (Durham) and Ian M. Adcock (London). The pediatric indications for beta-2-agonists were commented by Manfred G6tz (Vienna), and a large spectrum of clinical studies, reported by G. Boyd (Glasgow), A.P. Greening (Edinburgh), M.
