Adrenergic Antagonists Quiz

What is the mechanism of action of adrenergic antagonists?

• Inhibiting the release of adrenergic neurotransmitters

• Blocking the action of adrenergic neurotransmitters at adrenergic receptors

• Increasing the production of adrenergic neurotransmitters

• Enhancing the action of adrenergic neurotransmitters at adrenergic receptors

What are the pharmacological effects of adrenergic antagonists?

• Decreased heart rate, increased blood pressure, and contraction of smooth muscles

• Increased heart rate, decreased blood pressure, and contraction of smooth muscles

• Decreased heart rate, decreased blood pressure, and relaxation of smooth muscles
