The Effects of Nifedipine on Respiratory Mechanics Investigated by Theend-inflation Occlusion Method in the Rat
Overview
Affiliations
Context: Calcium channel blockers may theoretically exhibit relaxing effects not only on vascular smooth muscle but also on airway smooth muscle.
Objective: To investigate possible effects of nifedipine on respiratory mechanics in the rat.
Methods: Respiratory system mechanical parameters were measured by the end-inflation occlusion method in the rat in vivo before and after the intraperitoneal administration of nifedipine.
Results: We found that nifedipine affects respiratory mechanics, inducing a reduction of airway resistance and of respiratory system elastance, probably because of a relaxing action on airway and parenchimal smooth muscle cells.
Conclusion: Should these results be further confirmed by human investigations, a possible role of nifedipine in pharmacological respiratory system's diseases treatment may be suggested.
