[Inhalation of beta-stimulators: comparison of the effects of 6 different inhalation devices]

The efficacy of salbutamol inhalations with six different aerosol devices has been evaluated. In four crossover experiments 38 patients with stable asthmatic airway diseases inhaled salbutamol with a pressurized metered-dose inhaler, with a powder inhaler, with two different jet nebulizers, an ultrasonic nebulizer, and an IPPB device. The bronchodilator response was assessed by measurements of FEV1 and specific airway conductance before and after the inhalations.
