Nucleoside antiviral drugs. After entering the cell, this product is rapidly phosphorylated to a monophosphate compound, and then becomes a triphosphate compound through the action of cellular kinase. Its phosphorylation in cells infected with cytomegalovirus is faster than that in normal cells. Ganciclovir can competitively inhibit DNA polymerase and incorporate into the DNA of viruses and host cells, thereby inhibiting DNA synthesis. This product has a stronger inhibitory effect on viral DNA polymerase than host cell polymerase. In animal experiments, this product has teratogenic, carcinogenic, immunosuppressive effects and reproductive system toxicity.

It has strong anti-inflammatory, liver cell membrane protection and liver function improvement effects. It can reduce the increase of serum alanine aminotransferase and aspartate aminotransferase caused by carbon tetrachloride, thioacetamide and D-galactosamine, significantly reduce the morphological damage of D-galactosamine to the liver and improve the chronic damage of immune factors to the liver morphology.

This product is a proton pump inhibitor of gastric parietal cells, which can specifically inhibit the secretory microtubules and H, K-ATPases on the tubular vesicles in the cytoplasm of the parietal cell apical membrane, thereby effectively inhibiting the secretion of gastric acid. It can not only non-competitively inhibit the gastric acid secretion caused by gastrin, histamine, choline, food, and stimulation of the vagus nerve, but also inhibit part of the basic gastric acid secretion that is not affected by choline or H2 receptor blockers. It also has a strong and lasting inhibitory effect on the gastric acid secretion caused by dibutyl cyclic adenosine monophosphate (DCAMP) stimulation that cannot be inhibited by H2 receptor antagonists. In addition, this product also has an inhibitory effect on the secretion of pepsin, has no obvious change in gastric mucosal blood flow, and does not affect body temperature, gastric cavity temperature, arterial blood pressure, venous hemoglobin, arterial oxygen partial pressure, carbon dioxide partial pressure and arterial blood pH.

An immune bidirectional regulatory drug that induces and promotes the differentiation, maturation and activation of T lymphocytes and their subsets, regulates the proportion of T lymphocytes, enhances the body's cellular immune function, prompts T lymphocytes to secrete lymphokines, increases the level of lymphokine receptors on T cells, activates T helper cells to enhance lymphocyte responses, affects the chemotaxis of NK precursor cells and enhances their cytotoxicity, and enhances the body's ability to resist radiation.

It can cause the proliferation of cytotoxic T cells, natural killer cells and lymphokine-activated killer cells and enhance their killing activity. It can also promote the secretion of antibodies and interferon by lymphocytes. It has anti-viral, anti-tumor and immune-enhancing effects.

This product is a lymphokine that can proliferate cytotoxic T cells, natural killer cells and lymphokine-activated killer cells and enhance their killing activity. It can also promote lymphocytes to secrete antibodies and interferons, and has anti-viral, anti-tumor and immune enhancement effects. Long-term toxicity tests on animals have shown that no abnormalities were found in blood picture, blood and urine biochemical tests, circulatory system examinations, and pathological histological examinations.
