[Pharmacology and Toxicology] This product is a competitive angiotensin-converting enzyme inhibitor, which can not convert angiotensin I into angiotensin II, thereby reducing peripheral vascular resistance, and reducing sodium and water retention by inhibiting aldosterone secretion. This product can also expand peripheral blood vessels by interfering with the degradation of bradykinin. For patients with heart failure, this product can also reduce pulmonary capillary wedge pressure and pulmonary vascular resistance, increase cardiac output and exercise tolerance time.
[Pharmacokinetics] This product absorbs quickly after oral administration, and the absorption rate is above 75%. It takes effect 15 minutes after oral administration and reaches the peak concentration of blood for 1 to 1.5 hours. Lasts 6 to 12 hours. 25% to 30% of the product in the blood circulation binds to the protein. The half-life is shorter than 3 hours, and drug retention occurs when kidney function is impaired. The antihypertensive effect is progressive and reaches the maximum therapeutic effect in about several weeks. Metabolized into disulfide in the liver. This product is excreted by the kidneys, about 40% to 50% is discharged in the original form, and the rest are metabolites, which can be removed during hemodialysis. This product can not pass the blood-brain barrier. This product can be secreted through the milk and can pass through the placenta.
