Methods for adjusting the dosage of antihypertensive drugs and criteria for evaluating their antihypertensive effects
How to adjust the dosage of antihypertensive medication?
Some hypertensive patients may need to adjust their medication if the antihypertensive effect is not ideal or if adverse reactions occur after a period of use.
If a low-dose medication is effective but does not achieve the desired blood pressure level, and the patient can tolerate it or if adverse reactions are minimal, the dosage can be increased or another medication with synergistic effects and whose adverse reactions can offset each other can be added. The maximum antihypertensive effect of diuretics and long-acting antihypertensive drugs (such as amlodipine) often takes half a month to one month to appear. Therefore, when adjusting the dosage of long-acting drugs, it is advisable to wait about one month before considering adjusting the dosage and medication.
However, for severe hypertension, blood pressure must be controlled as early as possible. The dosage can be gradually increased and combined medications can be used earlier. For stage 2 or higher hypertension, combination therapy is often required to achieve the ideal blood pressure level.
For non-severe or acute hypertension, if blood pressure has been stable for more than one year after treatment, a reduction in dosage can be considered to reduce possible adverse reactions, but without affecting the efficacy.
When monitoring the antihypertensive effect after taking medication, it is best to measure blood pressure at the same time every day. In addition to understanding the patient's subjective feelings, necessary laboratory tests should be performed to understand the status of target organs and any adverse drug reactions.
How to evaluate the effectiveness of antihypertensive medication?
The effectiveness of antihypertensive medication should be evaluated regularly, usually over a period of one year.
A blood pressure record of <140/90 mmHg for more than 3/4 of the year (>9 months) is considered excellent.
A blood pressure record of <140/90 mmHg for more than 1/2 of the year (>6 months) is considered acceptable.
A blood pressure record of <140/90 mmHg for less than 1/2 of the year (<6 months) is considered poorly controlled. Dosage adjustment or addition of another medication is necessary.
Thin people should also be wary of high blood lipids: genetic and dietary factors and early prevention guidelines.
This article dispels the misconception that "only obese people get high cholesterol," explaining that thin people can also experience abnormal cholesterol levels due to factors such as genetics and poor diet. It emphasizes the importance of managing cholesterol scientifically and preventing cardiovascular and cerebrovascular diseases through the "three early" principles of early detection, early prevention, and early treatment.

Initiating lipid prevention in childhood: Regular check-ups and a "five-low" diet guideline
This article emphasizes that lipid prevention should begin in childhood, following the "five lows" dietary principle, and regular physical examinations to detect asymptomatic lipid abnormalities early. It specifically points out that high-risk groups such as those with a family history of lipid abnormalities or obesity need to strengthen lipid monitoring, while the general population and those over 40 years of age should also undergo examinations at the recommended frequency to prevent cardiovascular and cerebrovascular diseases from the source.
