Hope your Thursday treated you well! Heres your answer to the #NBDE Mastery #QOTD: Question: Propranolol functions as an antianginal through which of the following mechanisms? Answer: A. Blocking the beta-adrenergic receptors of cardiac muscle Rationale: Propranolol- is the first non-selective beta blocker developed and is used to treat hypertension, anxiety, and panic attacks. Propranolol blocks the action of epinephrine and norepinephrine on both β1- and β2-adrenergic receptors and exhibits little intrinsic sympathomimetic activity. Due to its high penetration across the blood brain barrier, lipophilic beta blockers such as propranolol and metoprolol are more likely to cause sleep disturbances such as insomnia, vivid dreams, and nightmares.
