Is it normal for blood pressure to be around 130 mmHg over 80 mmHg after taking antihypertensive medication?

Blood pressure readings of over 130 mmHg systolic and over 80 mmHg diastolic generally refer to a systolic pressure above 130 mmHg and a diastolic pressure above 80 mmHg. After taking antihypertensive medication, having a systolic pressure slightly above 130 mmHg and a diastolic pressure slightly above 80 mmHg is usually considered normal. The detailed explanation is as follows:

The flow of blood within the human body exerts a certain pressure on the walls of blood vessels, clinically known as blood pressure, which consists of systolic pressure (when the heart beats) and diastolic pressure (when the heart rests). Normally, systolic pressure should range between 90–140 mmHg, and diastolic pressure between 60–90 mmHg. If either systolic or diastolic pressure exceeds the upper limit of this normal range, hypertension can be diagnosed. Patients are required to take antihypertensive medications under medical supervision. If blood pressure decreases to slightly above 130 mmHg systolic and slightly above 80 mmHg diastolic after taking medication, this indicates that blood pressure has returned to within the normal range—a normal and expected outcome—suggesting that the antihypertensive medication is effectively controlling hypertension.

When taking antihypertensive drugs, patients should consult their doctor in advance and strictly follow medical instructions regarding dosage to avoid abnormally low blood pressure caused by excessive medication. If any physical discomfort or unusual fluctuations in blood pressure occur during daily life, prompt medical evaluation at a hospital is recommended.
