Rapid antihypertensive drugs: First, consider nifedipine, which takes effect in 30-60 minutes orally and can maintain its effect for 3 hours, and can take effect in 1-5 minutes sublingually. If it is injected intravenously, the effect can appear within one minute, and the plasma protein binding rate also reaches more than 90%, which is significant for hypertensive patients to lower blood pressure. The plasma renin activity is increased, and it is more sensitive to the smooth muscle of small arteries than veins, so that the peripheral vascular resistance is reduced and the blood pressure is lowered; secondly, you can consider the priligy, such as captopril, as well as lenopril, fosinopril, benazepril, etc. The effect is also quite fast, and the maximum antihypertensive effect can be achieved in 1-2 hours of oral administration, and the maintenance of 6-8 hours can reduce the peripheral vascular resistance and increase the blood flow of the kidney.
