        | How do beta agonists work? |  | Definition 
 
        | by stimulating adenyl cyclase --> increases cAMP concentrations and decreases the release of mediators |  |

        | Term 
 
        | How do anticholinergics work? |  | Definition 
 
        | suppresses the increase in cGMP (because ACH interacts with the muscarinic receptors on bronchiole smooth muscles) |  |

        | Term 
 
        | How do PDE4 inhibitors work? |  | Definition 
 
        | by selectively inhibiting PDE4, which is a major cAMP metabolizing enzyme. Essentially, it increases cAMP |  |
