Clinical Trial Summary

Contextualization: Exercise is a common triggers of bronchospasm in patients with asthma and healthy subjects. To prevent these symptoms frequently they have to use Short-Acting Beta2-Agonists. However, the cardiovascular effects of salbutamol during and after exercise remain poorly known.

Objective: To evaluate the effect of salbutamol on heart rate and blood pressure during exercise in patients with moderate or severe asthma and healthy individuals.

Methods: A randomized, double-blind, crossover study will be conducted which 13 individuals with moderate or severe persistent asthma and 13 healthy individuals aged between 20 to 59 years.

Patients will perform a maximal effort test on 2 nonconsecutive days, with either 400mcg Salbutamol or 4 placebo puffs. The order of use of placebo or salbutamol will be drawn. During the protocol, heart rate, blood pressure, perception of exertion and peak expiratory flow will be monitored.
