What is the dosage range for propranolol mentioned as part of the antidiuretic hormone dysfunction management?

• A. 30-120 mg/day
• B. 5-10 mg/day
• C. 150-300 mg/day
• D. 300-600 mg/day

Answer: (A)

Propranolol helps calm sympathetic overactivity that can accompany antidiuretic hormone dysfunction by blocking beta-adrenergic receptors, which lowers heart rate and other tachycardia-related symptoms. For this use, a moderate daily dose is appropriate, typically starting around 30 mg per day and carefully increasing to about 120 mg per day based on response and tolerability. This range provides enough beta-blockade to reduce symptoms without crossing into higher-dose risks like bradycardia, hypotension, or bronchospasm. Doses as low as 5–10 mg daily are usually insufficient for meaningful effect, while very high daily totals (150–300 mg or 300–600 mg) raise the risk of adverse effects and aren’t generally needed for this indication.
