개요

Shortly after the introduction of dexamethasone, betamethasone, which differs from dexamethasone only in configuration of the 16-methyl group, was made available for the treatment of rheumatic diseases and dermatologic disorders. This analogue, which contains a 16β-methyl group, has received sufficient clinical trial examination to indicate that it is as effective as dexamethasone or, perhaps, even slightly more active. Although this drug has been reported to be less toxic than other steroids, some clinical investigators suggest that it is best used for short-term therapy.

화학적 성질

White to Off-White Solid

용도

Betamethasone is a glucocorticoid used as an anti-inflammatory agent.

일반 설명

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).

부작용

Toxic side effects, such as increased appetite, weight gain, and facial mooning, occur with prolonged use.

Safety Profile

Low toxicity by ingestion. Anexperimental teratogen. Other experimental reproductiveeffects. When heated to decomposition it emits toxicfumes of F-.

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.
