Propranolol is used in the management with a daily dosage of?

• A. 20-60 mg/day
• B. 30-120 mg/day
• C. 50-150 mg/day
• D. 100-200 mg/day

Answer: (B)

Propranolol dosing is individualized and usually started at a low level with gradual adjustment, because it works by blocking beta receptors to slow heart rate, reduce blood pressure, and lessen sympathetic symptoms. Its relatively short half-life means that splitting the daily dose helps maintain steady beta-blockade and keeps effects more even throughout the day.

For chronic, non-acute management across multiple conditions, a moderate total daily dose is commonly used because it provides enough beta-blockade to control symptoms without causing excessive fatigue, bradycardia, or hypotension. Doses in this middle range can be tailored up or down based on response and tolerability, making it a practical default for general maintenance.

Ranges that are too low may not achieve the desired therapeutic effect, while those that are too high increase the risk of adverse effects and may not be necessary for many patients. Hence, a moderate daily dose range is considered the best general choice for ongoing management.
