The use of acebutolol with hydrochlorothiazide in hypertension
Insights
The combination of acebutolol and hydrochlorothiazide effectively lowers blood pressure in hypertensive patients. This combination therapy demonstrates superior antihypertensive effects compared to acebutolol alone across all severity levels.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Hypertension is a prevalent cardiovascular condition requiring effective management.
- Combination therapy is often necessary to achieve target blood pressure goals.
Purpose of the Study:
- To evaluate the antihypertensive efficacy of combined acebutolol (400 mg) and hydrochlorothiazide (25 mg).
- To compare the combination therapy's effectiveness against acebutolol monotherapy.
Main Methods:
- A study involving 22 patients with varying degrees of hypertension (mild, moderate, severe).
- Blood pressure measurements were taken in supine and standing positions before and after treatment.
- Patient outcomes were categorized as good, fair, or poor.
Main Results:
- Significant reductions in both supine (190/116 to 147/91 mm Hg) and standing (188/117 to 143/94 mm Hg) blood pressure were observed.
- Good results were achieved in 68% of patients.
- The combination therapy showed improved efficacy across all hypertension severities compared to acebutolol alone, particularly in mild hypertension (100% good results).
Conclusions:
- The combination of acebutolol and hydrochlorothiazide is an effective antihypertensive treatment.
- This combination therapy offers enhanced efficacy over acebutolol monotherapy for managing hypertension.
- Patient age, sex, and duration of hypertension did not significantly impact treatment outcomes.
Abstract:
The antihypertensive effect of acebutolol 400 mg and hydrochlorothiazide 25 mg in combination have been assessed in 22 patients with mild, moderate and severe hypertension. In the supine position, blood pressure went down from an average of 190/116 mm Hg to 147/91 mm Hg after treatment, while in the standing position, blood pressure went down from an average of 188/117 mm Hg to 143/94 mm Hg. Age, sex and duration of hypertension have no significant influence upon the antihypertensive effect of this combination. Good results were obtained in 68% of the patients, fair results in 23% and poor results in another 9%. Compared with the use of acebutolol alone, its combination with hydrochlorothiazide showed better results. In mild hypertension good results increased from 75% after acebutolol only to 100% after this combination. In moderate hypertension the percentage of good results increases from 47% to 60% and in severe hypertension good results increased from 50% to 67%. Increase of decrease in heart rate had no relation to the antihypertensive effect of this combination.
