Propranolol Quiz

Propranolol: Multiple Choice Questions and Answers

• Propranolol is a non-selective beta-blocker.
• It primarily acts by blocking beta-1 and beta-2 adrenergic receptors.
• Beta-adrenergic receptors are crucial in regulating heart rate, blood pressure, and other functions.
• Blocking these receptors can result in lower heart rate and blood pressure.
• Propranolol is used to treat various conditions like hypertension, angina, and arrhythmias.
• Common side effects of propranolol include fatigue, dizziness, and bradycardia.
• Propranolol may mask symptoms of hypoglycemia in diabetic patients.
• It should be used cautiously in patients with asthma or COPD due to potential bronchospasm.
• Propranolol is a competitive inhibitor of beta-adrenergic receptors.
