Short-acting antihypertensive medications work in a few minutes or half an hour, while long-acting antihypertensive medications usually work in about an hour.
The fastest way for antihypertensive drugs to work is to take short-acting antihypertensive drugs under the tongue, such as nifedipine and captopril, which usually take only a few minutes to have an effect. Oral intake of these short-acting antihypertensive drugs usually takes about half an hour to take effect and lasts for about 4 to 5 hours.
Long-acting antihypertensive drugs, such as amlodipine and metoprolol, generally take effect about one hour after taking them, and the antihypertensive effect can last for more than 24 hours.
Clinically, it is recommended that hypertensive patients take long-acting antihypertensive drugs to maintain stable blood pressure and reduce damage to target organs caused by fluctuations in blood pressure.
The use of medication should be under the guidance of a doctor and should not be used without authorization.
