Q

Mechanism of Action of SABAs

A

Binds to BETA2 adrenergic receptors in the airway. This leads to activation of adenyl cyclase resulting in increased levels of cyclic-3’,5’-adenosine monophosphate (cAMP). Increases in cAMP inhibits phosphorylation of myosin and decrease intracellar calcium. Decreased intracellar calcium relaxes smooth muscle airways.

Q

Mechanism of Action for SAMAs

A

Inhibits cholinergic receptors in bronchial smooth muscle. This results in decreased concentrations of cyclic guanosine monophophate (cGMP). Decreased levels of cGMP results in bronchodilation.
