The general effective dose is 10-20 mg (1~2 tablets) per day. The maximum dose per day should not exceed 40 mg (4 tablets).

【Pharmacology and Toxicology】
This product is an angiotensin converting enzyme inhibitor. After oral administration, it is hydrolyzed into enalapril (Enalaprilat), which strongly inhibits angiotensin-converting enzyme, reduces angiotensin II content, causes systemic vasodilation, and causes hypotension. It has significant antihypertensive effect on type II kidney hypertension, type I hypertension and spontaneous hypertensive rat models.
Enalapril is a prodrug in which the ethyl ester moiety is rapidly hydrolyzed in the liver and converted to its effective metabolite, enalapril, to exert a hypotensive effect. About 68% of oral enalapril was absorbed. This product was taken with food and did not affect its bioavailability. The plasma enalapril concentration peaked 1 hour after taking the drug. After 3.5 to 4.5 hours of administration, the plasma concentration of enalapril reached a peak with a half-life of 11 hours. Hepatic dysfunction is delayed by the conversion of enalapril to enalapril. After 20 minutes of administration, enalapril was widely distributed throughout the body. The liver, kidney, stomach and small intestine had the highest drug concentration and the lowest concentration in the brain. Oral 2 times a day, two days later, enalapril binds to angiotensin-converting enzyme to reach a steady state, and the final half-life is extended to 30-35 hours. Enalapril is mainly excreted by the kidneys. In patients with severe renal insufficiency (creatinine clearance below 30 ml/min) drug accumulation can occur, and the drug can be removed by hemodialysis.
