Beschreibung

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.

Chemische Eigenschaften

Allgemeine Beschreibung

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).

Nebenwirkungen

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

Sicherheitsprofil
