Data on the effect of Probon on respiration.

Therapia Hungarica (English edition) 1989

On the basis of the results of earlier published and recent examinations it could be concluded that among analgesics Probon is the first of choice especially in case of chronic pain accompanying chronic respiratory tract diseases. The value of the drug is also supported by the fact that the number of patients suffering from chronic obstructive respiratory failure increases continuously, since the equilibrium of these patients is very unstable; the smallest injury, such as an increase in secretion, a decrease in diaphragmatic movement, or chest expansion caused by pain, or even drug-induced respiration depression, may very easily upset this equilibrium.
