[image] Describe the pathway and where different drugs for asthma or COPD work along it |
|
Definition
ATP (AC) -> cyclic AMP -> bronchodilation -> PDE destroys cyclic AMP -> AMP. medications act on these enzymes to cause bronchodilation and inc production of cyclic AMP. Acetylcholine and adenosine -> bronchoconstriction. beta agonists activate adenylate cyclase -> inc cyclic AMP. muscarinic agonists inhibit effect of acetylcholine and prevents bronchoconstriction. theophylline and roflumilast inhibit PDE enzyme resulting in a dec in the destruction of cyclic AMP -> bronchodilation. Theophylline inhibits the effects of adenosine -> prevents bronchoconstriction |
