Drugs available to treat asthma have improved considerably over the past th
ree decades and understanding of the disease process is continually improvi
ng. However, the incidence of asthma is increasing and the cause(s) of this
increase are not yet identified. Asthma is often underdiagnosed and undert
reated. Poor compliance with medication is also an important consideration
in how effective management strategies can be. The aim of current asthma tr
eatment, according to the Global Initiative for Asthma (GINA), is to contro
l the disease. However, two surveys. one in Europe and the other in the U.S
.A. indicate that the objectives of treatment guidelines are not being met.
Patients were shown to experience high rates of exacerbations and require
many doses of reliever medication. There was also a large difference betwee
n patient and physician perceptions of treatment-this needs to be countered
by improved education for both the general public and healthcare professio
nals. Formoterol, which is the only beta (2)-agonist to possess both fast-
and long-acting properties, may help to improve patient compliance by allow
ing a single inhaler to be used for both maintenance and as-needed therapy
However, although formoterol is already widely used as maintenance therapy,
current treatment guidelines do not include the use of formoterol as first
-line reliever medication. Evidence is increasing to support as-needed use
and a large, randomized effectiveness study in 18000 patients across the wo
rld is ongoing to assess the safety and efficacy of formoterol as needed in
a real-life setting. The results from the Real-Life Effectiveness of Oxis
(R) Turbuhaler (R) (RELIEF) study should help to establish the position of
formoterol as an effective first-line reliever medication and ultimately le
ad to the inclusion of formoterol as needed in treatment guidelines, (C) 20
