Statement re Asthma Treatment

AstraZeneca PLC 29 August 2000 ASTRAZENECA RECEIVES FIRST APPROVAL FOR SYMBICORT TURBUHALER FOR THE TREATMENT OF ASTHMA AstraZeneca has gained its first approval for Symbicort Turbuhaler, a new and innovative asthma treatment. Containing the corticosteroid budesonide and fast and long-acting bronchodilator formoterol in a single inhaler (Turbuhaler), Symbicort is being hailed as a significant new step in the field of asthma management. The rationale behind using budesonide and formoterol in a single inhaler is based on the landmark Pauwels et al study published in the New England Journal of Medicine. This study shows that when budesonide and formoterol are used together, the rate of severe asthma attacks in patients with moderate to severe asthma is reduced by between 26 and 63 percent, and mild attacks are reduced by up to 62 percent. The Pauwels' study also shows that adding formoterol to budesonide also improves control of asthma in terms of patients' lung function and night-time symptoms. Such benefits have the additional effect of providing a significant and sustained improvement in patients' quality of life. One of the unique benefits Symbicort provides for patients is that dosing may be adjusted with the same single inhaler, as prescribed by the physician. Patients starting out on Symbicort are likely to be prescribed two inhalations twice daily. When good asthma control is achieved, the patient can then be maintained on a lower dose using the same inhaler with the option of once daily dosing. If asthma deteriorates, the prescriber can return the dose to the original two inhalations twice daily using the same single inhaler. No other currently available asthma therapy provides this degree of convenience for patients and physicians. Formoterol, one of the components of Symbicort, is the only long-acting beta-agonist with an onset of effect as rapid as that of short-acting beta agonists and with a safety profile at least as good. Symbicort Turbuhaler is expected to be available on prescription in Sweden from September 2000. Further approvals are expected throughout Europe later this year.
