Betamethasone Chemical Properties,Uses,Production

hormone drugs

Betamethasone, belongs to adrenal corticosteroids, it is a isomer of dexamethasone , and the role of betamethasone is similiar to prednisolone and dexamethasone , it has anti-inflammatory, anti-rheumatic, anti-allergic and suppression of the immune and other pharmacological effects, its anti-inflammatory effect is stronger than dexamethasone, triamcinolone, hydrocortisone etc. , it can reduce and prevent tissue response to inflammation and eliminate heat, redness and swelling caused by local non-infectious inflammation, thereby reducing the performance of inflammation, anti-inflammatory effect of this product 0.3mg is equal to dexamethasone 0.75mg, prednisone 5mg or 25mg cortisone .
Betamethasone sodium retention effect is a hundred times more than hydrocortisone, in primary adrenal hypofunction, it can be used together with glucocorticoid for replacement therapy ,and it is used for preventing or inhibiting cell-mediated immune response, delaying allergic reactions and reducing the primary immune response expansion ,it is used for low renin and low aldosterone syndrome and autonomic neuropathy induced orthostatic hypotension.
Currently betamethasone is also used for the treatment of active rheumatoid arthritis, rheumatoid arthritis, lupus, severe bronchial asthma, severe dermatitis, acute leukemia, atopic dermatitis, eczema, neurodermatitis, seborrheic dermatitis, and pruritus and comprehensive treatment of certain infections.
The product is contraindicated in severe psychiatric history, active duodenal ulcer, recent gastrointestinal anastomosis, heavier osteoporosis, overt diabetes, severe hypertension, virus , bacterial, fungal infections which are failed to control by the use of antimicrobial agents , thrombophlebitis, skin infections, such as impetigo, tinea, jock itch and so on.

Chemical Properties

White crystalline powder. Mp 231-234 deg.] C (decomposition). Odorless. Acetate Betamethasone ([987-24-6]) is also white crystalline powder, melting point 205-208 ℃, slightly soluble in alcohol, ethanol, and very slightly soluble in chloroform or ether, insoluble in water, odorless.


Hormone drugs.It is mainly used for anti-inflammatory and anti-allergic. It is suitable for rheumatoid arthritis and various skin diseases. Betamethasone role is similiar to dexamethasone, its anti-inflammatory effect is stronger than dexamethasone, triamcinolone, hydrocortisone and it has few side effects.

production method

According to U.S. Patent No. 3,164,618, betamethasone acetate is dealt with hydrochloric acid in methanol-chloroform-water mixture , it can be converted to betamethasone.

General Description

Betamethasone, 9-fluoro-11β,17,21-trihydroxy-16β-methylpregna-1,4-diene-3,20-dione,is available as a variety of ester derivatives.
Betamethasone valerate, USP (17-valerate)
Betamethasone acetate, USP (21-acetate)
Betamethasone sodium phosphate, USP (21-sodiumphosphate)
Betamethasone dipropionate, USP (17-propionate,21-propionate).

Purification Methods

Betamethasone crystallises from ethyl acetate, and has max at 238nm (log 4.18) in MeOH. The 21-acetate [287-24-6] crystallises from Me2CO/Et2O (charcoal) m 196-201o (205-208o) and has [] D 20 +140o (CHCl3). [Taub et al. J Am Chem Soc 82 4012 1960, Olivetto et al. J Am Chem Soc 80 6688 1958, Beilstein 8 IV 3501.]
