B2 Adrenoceptor agonists |
Salbutamol, Salmeterol increase cAMP, which leadsto bronchodilation and possible effects on mast cells. |
|
Methylxanthines |
Theophylline phosphodiesteraseinhibitor, this prevents the conversion of cAMP to AMP, thus there is amaintained increase in cAMP, which leads to increased PKA and increasedbronchodilation. |
|
Muscarinic receptor antagonists: |
Ipratropium Inhibit ACh-mediatedbronchoconstriction. These drugs not effect histamine leukotriene-mediatedconstriction. |
|
Leukotriene receptor antagonists: |
Montelukast inhibit the conversion ofcys-LT2 to cys-LT1, which reduces bronchospasm, plasma exudation and eosinophilrecruitment. |
|
Glucocorticoids: |
Beclomethasone, Prednisolone Anti inflammatory steroids |
|
Anti-IgE |
Omalizumab binds to IgE and preventscross-linking on the surface of mast cells. |
|
Cromoglycate |
These drugs potentially stabilise mast cells andinhibit T-cells. |
