It has both histamine H1 receptor antagonism and the effect of inhibiting the release of allergic reaction mediators. It not only has a strong anti-allergic effect, but also has a longer duration of efficacy. Therefore, it is more effective in preventing various bronchial asthma attacks and exogenous asthma than endogenous asthma.

It is hydrolyzed in the liver to enalaprilat, which is a renin angiotensin converting enzyme inhibitor (ACEI). By inhibiting ACE, it reduces the formation of angiotensin II, reduces aldosterone secretion, increases plasma potassium concentration, weakens the negative feedback effect of Ag II on renin secretion, and increases plasma renin activity. At the same time, it increases the activity of the circulating and local kallikrein-kinin system and the prostaglandin system. It can reduce supine and sitting blood pressure in hypertensive patients, significantly reduce peripheral vascular resistance, and does not affect renal blood flow or glomerular filtration rate. For patients with heart failure, it can reduce peripheral circulation resistance, increase venous capacity, reduce cardiac preload and afterload, and at the same time increase cardiac output, improve cardiac stroke index and stress capacity.

Interferes with the first step of folic acid synthesis. When used in combination with trimethoprim, it can double block the folic acid metabolism of bacteria, enhance the synergistic antibacterial effect, and reduce drug-resistant strains.

Selectively inhibits the action of dihydrofolate reductase. When used in combination with sulfamethoxazole, it can double-block the bacterial folate metabolism, enhance the synergistic antibacterial effect, and reduce drug-resistant strains.

Contains vitamin B12, folic acid and other nutrients, participates in the synthesis of nucleic acids, choline, amino acids and the metabolism of fats and sugars, promotes the development and maturation of red blood cells, maintains the hematopoietic function of the bone marrow, and is an important raw material for hematopoiesis.

It is trivalent iron, which is used as a raw material for hematopoiesis to promote hemoglobin synthesis and red blood cell maturation

Participate in the body's sugar metabolism process and maintain the normal functions of the nervous, cardiac and digestive systems

Participate in the metabolism of carbohydrates, proteins, nucleic acids and fats, improve the body's utilization of proteins, participate in cell growth and metabolism, and improve anemia symptoms

Contains a variety of B vitamins, which work together with the above raw materials to participate in the production of red blood cells and hemoglobin, promote the development and maturation of red blood cells, and reduce the adverse gastrointestinal reactions caused by iron supplements
