The current antihypertensive drugs are all long-acting antihypertensive drugs, that is, they can be taken once a day, and generally need to be observed for 5-7 days to reach a relatively stable level, and are more stable at 2-4 weeks. Therefore, when starting to take antihypertensive drugs, patients should not rush to measure blood pressure after taking the medication, because long-acting drugs do not work so quickly. In addition, if there is no effect after 3 days of dosing, it is not urgent to go for follow-up unless the blood pressure is very high. It is more appropriate to assess the efficacy after 2 weeks. For patients whose blood pressure does not reach the target, if the blood pressure reduction goal is not achieved after 4-12 weeks, the medication needs to be adjusted. Patients need to be reminded that the purpose of taking the medication is to control blood pressure to achieve the target, in order to reduce cardiovascular events to a greater extent, such as reducing cerebral hemorrhage, heart attack, and kidney damage.
