Product Description

In 1958, dexamethasone was synthesized by Arth and Oliveto respectively, and dexamethasone sodium phosphate was produced by Merck & Co. in 1960. More than 12 kinds of dexamethasone derivatives have been listed.

The chemical structure of dexamethasone is the introduction of fluorine atoms in the B ring 9 alpha of prednisolone and the introduction of methyl in the D Ring 16 alpha position; 9 alpha fluorine and 16 alpha methyl all enhance its anti-inflammatory activity significantly, while 16 alpha methylate significantly reduces the sodium retention side effect of dexamethasone. The clinical bioequivalent dose ratio of dexamethasone and prednisolone was 0.75:5, and the biological half-life was 36-54 hours, which was classified as long-acting glucocorticoid.

Dexamethasone, like other glucocorticoids, is widely used in various diseases, such as autoimmune diseases, allergies, inflammation, asthma, and Department of Dermatology and Ophthalmology, with the pharmacological effects of anti-inflammatory, anti endotoxin, immunosuppressive, anti shock and stress response. Dexamethasone sodium phosphate injection is a necessary emergency medicine for rescuing the dying patients. In the past ten years, clinicians have applied dexamethasone sodium phosphate in the treatment and prevention of drug allergies caused by various Chinese and Western medicine and the treatment of fever caused by the virus, which has made the clinical use of dexamethasone increasing year by year. The largest dexamethasone market in the world.
