What is Dexamethasone?
is a glucocorticoid and a long-acting glucocorticoid. It has many effects, mainly in two ways.
One is the anti-inflammatory effect. The use of dexamethasone can inhibit the inflammatory response, thereby reducing the performance of inflammation, and the other is the immunosuppressive effect. By using dexamethasone, it can suppress the immune response and slow down the allergic reaction. There are some autoimmune diseases. After use, the progression of the disease can be avoided and the autoimmune function can be restored to normal.

3. Isotonic specific volume (90.2K): 812.3

Dexamethasone mechanism of action
Its pharmacological effects are mainly anti-inflammatory, anti-toxic, anti-allergic and anti-rheumatic, and it is widely used in clinical practice. Easily absorbed from the digestive tract, the plasma T1/2 is 190 minutes, and the tissue T1/2 is 3 days. After intramuscular injection of dexamethasone sodium phosphate or dexamethasone acetate, the peak plasma concentration is reached at 1 hour and 8 hours, respectively. . The plasma protein binding rate of this product is lower than other corticosteroids. The anti-inflammatory activity of this product 0.75 mg is equivalent to 5 mg prednisolone. Adrenal corticosteroids have stronger anti-inflammatory, anti-allergic and anti-toxic effects than prednisone, and have a very light effect on water and sodium retention and promoting potassium excretion. They can be injected intramuscularly or intravenously to inhibit the pituitary and adrenal glands.
1. Anti-inflammatory effect: It can reduce and prevent the tissue's response to inflammation, thereby reducing the performance of inflammation. Hormones inhibit the accumulation of inflammatory cells, including macrophages and white blood cells, at the site of inflammation, and inhibit phagocytosis, the release of lysosomal enzymes, and the synthesis and release of inflammatory chemical mediators.
2. Immunosuppressive effects: including preventing or suppressing cell-mediated immune responses, delayed allergic reactions, reducing the number of T lymphocytes, monocytes, and eosinophils, and reducing the ability of immunoglobulin to bind to cell surface receptors, And inhibit the synthesis and release of interleukins, thereby reducing the transformation of T lymphocytes into lymphoblasts, and reducing the expansion of the primary immune response. It can reduce the passage of immune complexes through the basement membrane, and can reduce the concentration of complement components and immunoglobulins.
A new process for the production of dexamethasone 21-hydroxy compound. The intermediate 21-acetate is used as the substrate, and an appropriate amount of methanol containing 0-10% chloroform is used as a solvent to semi-dissolve the substrate, and a base is used as a catalyst. The hydrolysis reaction is carried out, and after the reaction is complete, the reaction solution is neutralized with acetic acid, the reaction solution is concentrated under reduced pressure to an appropriate volume, the temperature is lowered, the filter cake is washed, and dried to obtain 21-hydroxyl compound. The process can shorten the production cycle, improve the quality and yield of 21-hydroxyl compounds, and reduce the content of impurities in 21-hydroxyl compounds.
Dexamethasone half life
The biological half-life of dexamethasone is about 190 minutes, and the tissue half-life is about 3 days. More than 65% of the drug is excreted in urine within 24 hours, mainly inactive metabolites.
How Dexamethasone uses for?
It acts as the main therapeutic drug in the treatment of different diseases. In some diseases, it also acts as an auxiliary treatment. For example, it is the main therapeutic drug in allergic and autoimmune diseases. Some chemotherapy processes are also the main chemotherapy drugs. For example, the malignant lymphoma program contains hormonal drugs such as dexamethasone or prednisone as the main chemotherapy drugs. Secondly, in the treatment of nausea and vomiting caused by chemotherapy, dexamethasone is an adjuvant chemotherapy drug, which can stop vomiting. Its pharmacological effects are very powerful, and its usage and dosage are also very wide. When treating some basic allergic and autoimmune diseases, the method of administration can be oral or intravenous drip. For oral administration, the recommended starting dose for adults starts with a low dose, 0.75 to 3 mg, which is 1 to 4 tablets, two to four times a day. Maintain a certain dose, such as once a day, one piece at a time for maintenance, and the response of individual patients is different.
What's Dexamethasone side effect?
Clinically, the side effects of dexamethasone will first affect water and sodium. Because hormones can cause water and sodium storage, patients will experience increased blood pressure and promote potassium excretion, which will lead to hypokalemia and high sodium in patients. Blood pressure can cause high blood pressure, especially hormones in patients with severe hypertension should be used with caution. At the same time, it can affect the metabolism of sugar and fat, leading to fat redistribution. Therefore, if the hormone is used for too long, it will cause the patient to have a full moon face and buffalo back, similar to the clinical symptoms of Cushing syndrome. In addition, dexamethasone can also cause wounds to not heal because it affects tissue repair. For some severely infected patients, it can also cause infections that are not easy to control, especially for tuberculosis patients, which may cause some tuberculosis in the incubation period to be reactivated Status, aggravating infection. Dexamethasone can also promote the dissipation of calcium, and long-term clinical use of hormones is known to cause femoral head necrosis, which is caused by the loss of calcium by hormones. It can also lead to peptic ulcers, etc. These are common side effects of hormone application.
Dexamethasone and calcium chloride, sulfadiazine sodium, tetracycline hydrochloride, oxytetracycline hydrochloride, diphenhydramine, chlorpromazine, promethazine, sulfacetamide, procaine hydrochloride, scopolamine hydrobromide, etc. Compatibility is prone to turbidity or precipitation, making the drug ineffective; combined with furosemide and sodium salicylate can increase its toxicity.
