What is the primary mechanism of action of Albuterol?
(Select all that apply)
A. Beta-1 agonism leading to increased heart rate
B. Beta-2 agonism leading to bronchial smooth muscle relaxation
C. Stimulation of adenylyl cyclase
D. Decrease in cyclic AMP (cAMP) levels
B. Beta-2 agonism leading to bronchial smooth muscle relaxation
C. Stimulation of adenylyl cyclase
MOA: Beta-2 agonist; stimulation of adenylyl cyclase = inc cAMP = bronchial smooth muscle relaxation and cellular reuptake of K+
MOA: How does Albuterol lead to bronchial smooth muscle relaxation?
(Select all that apply)
A. By decreasing cyclic AMP (cAMP) levels
B. By stimulating adenylyl cyclase
C. By increasing cyclic AMP (cAMP) levels
D. By promoting cellular reuptake of potassium (K+)
Answer: B, C, D
Answer: B, C, D
MOA: Beta-2 agonist; stimulation of adenylyl cyclase = inc cAMP = bronchial smooth muscle relaxation and cellular reuptake of K+
