[A new method of administration of budesonide powder for the treatment of allergic rhinitis].

The efficacy and safety of a new device for administering powdered budesonide in allergic rhinitis was evaluated. This method eliminates the disadvantages of traditional preparations and improves dosing and administration, even at low nasal flow rates. A randomized, controlled, single-blind study was made in 66 patients with allergic rhinitis, half of whom were assigned to the experimental treatment (powdered budesonide) and half to a standard aerosol. Results showed that both preparations were very effective (p < 0.01) in controlling rhinitis symptoms and not significantly different. However, the overall patient evaluation was significantly better (p < 0.01) in the group treated with powdered budesonide. Both treatments elicited a similar tolerance, although tolerance of powdered budesonide was slightly better. To conclude, treatment with the new powdered budesonide dispenser was as effective and well-tolerated as standard treatment, and better accepted by patients.
