The response to antihypertensive drugs is predictable. The absence of precise prescription recommendations to
treat arterial hypertension (HT) lead to use drugs unable to reduce blood pressure (BP) to target values.
We published ATOM study, in which we found significant differences in the ability to reduce BP between the different drugs.
The objective of the study was to determine the expected decrease in blood pressure with the use of commercialized doses of the
drugs commonly used in the treatment of HT in clinical practice, to avoid the use of drugs or combinations that even with the best
response, are unable to obtain the necessary BP decrease to reach the goal.
Methods: The analysis was based on the results of the ATOM study. To convert the mean doses of the different drugs and
combinations in commercialized doses, the conclusions of the study by Law et al have been applied.
Results: Based on the results, two tables were drawn, one for systolic BP and the other for diastolic BP, where the doses of the
different drugs and combinations are classified according to the BP decrease that can be expected from them. In order to favor the
use of the tables in clinical practice, the different drugs have been grouped in intervals of 10millimeters of mercury (mmHg) for the
decrease of the systolic BP and of 5 mmHg for the diastolic BP.
Conclusions: Recommendations for the use of antihypertensive treatments should not be limited to pharmacological families.
They should also consider differences between drugs or specific combinations. From the data of the ATOM study we have
implemented tables that express the effect of the drugs commonly used in clinical practice and that should allow the clinicians to
choose with care the treatment to use.
