    Summary

    Once-daily propranolol is effective for managing essential hypertension. This dosing strategy maintained blood pressure control and resulted in infrequent, mild side effects in patients previously on four-times-daily regimens.

    Area of Science:

    • Cardiology
    • Pharmacology

    Background:

    • Essential hypertension is a common condition requiring consistent medication adherence.
    • Propranolol is a beta-blocker frequently prescribed for hypertension.
    • Current propranolol regimens often involve multiple daily doses, potentially impacting patient compliance.

    Purpose of the Study:

    • To evaluate the efficacy and safety of once-daily propranolol administration in patients with essential hypertension.
    • To compare blood pressure control and side effect profiles between once-daily and multiple-daily-dose propranolol regimens.

    Main Methods:

    • Twenty patients with essential hypertension on diuretic and propranolol qid were switched to a single morning dose of propranolol.
    • Blood pressure was measured in standing and supine positions at the end of the dosing interval.
    • Patient-reported side effects were systematically assessed over four bi-weekly evaluations.

    Main Results:

    • Mean blood pressure remained statistically similar between once-daily and qid propranolol dosing.
    • The daily dose of propranolol ranged from 80 to 320 mg.
    • Reported side effects were infrequent and generally mild.

    Conclusions:

    • Once-daily administration of propranolol is a viable option for patients with essential hypertension.
    • This simplified dosing regimen maintains therapeutic efficacy without increasing adverse events.
    • Single-daily dosing may improve medication adherence in hypertensive patients.
