Quizplus · Accepted Answer

Aminophylline is a phosphodiesterase inhibitor.It is an example of drugs in the xanthine group.Common phosphodiesterase drugs are found in the methylxanthine group.Cyclic 3',5'-AMP is broken down into 5'-AMP by the enzyme phosphodiesterase.If the action of phosphodiesterase can be blocked or inhibited,more 3',5'-AMP will remain in the lungs,resulting in better bronchodilation.Phosphodiesterase inhibitors act in this way.
