What is the mechanism of action of Tiotropium (SPIRIVA) - ANSWER It
does not display selectivity for specific muscarinic receptors, when
topically applied it acts mainly on M3 muscarinic receptors[8] located on
smooth muscle cells and submucosal glands. Th is leads to a reduction in
smooth muscle contraction and mucus secretion and thus produces a
bronchodilatory effect.

What is the mechanism of action of albuterol? - ANSWER Activation of
beta adrenergic receptors lead to relaxation of the muscle of the lung

Beta adrenergic receptor are coupled with stimulatory g -protein of the
the d-anelyl cyclase> This enzyme produces the second messennger
cyclic AMP (in the lungs it cAMP decreases calcium concentration w/in
cells and and activates protein kinase A. Both of these inactivates
myosin activase kinase and myosin like phosphatase
They open large conductants of hyperpolarize airway smooth muscle
cells
