DESCRIPTION
Betamethasone Valerate Foam, 0.12% contains betamethasone valerate,
USP, a
synthetic corticosteroid, for topical dermatologic use. The
corticosteroids constitute a
class of primarily synthetic steroids used topically as
anti-inflammatory agents.
Betamethasone valerate is 9-fluoro11ß,17,
21-trihydroxy-16ß-methylpregna-1, 4-diene-
3, 20-dione 17-valerate, with the empirical formula C
H
FO , a molecular weight of
476.58. The following is the chemical structure:
BETAMETHASONE VALERATE
Betamethasone valerate
Betamethasone valerate is a white to practically white, odorless
crystalline powder, and
is practically insoluble in water, freely soluble in acetone and in
chloroform, soluble in
alcohol, and slightly soluble in benzene and in ether.
Betamethasone Valerate Foam, 0.12% contains 1.2 mg betamethasone
valerate USP,
per gram in a thermolabile hydroethanolic foam vehicle consisting of
cetyl alcohol, citric
acid, ethanol (60%), polysorbate 60, potassium citrate, propylene
glycol, purified water,
and stearyl alcohol pressurized with a hydrocarbon (propane/butane)
propellant.
CLINICAL PHARMACOLOGY
Like other topical corticosteroids, betamethasone valerate foam has
anti-inflammatory,
antipruritic, and vasoconstrictive properties. The mechanism of the
anti-inflammatory
activity of the topical steroids, in general, is unclear. However,
corticosteroids are
thought to act by the induction of phospholipase A inhibitory
proteins, collectively called
lipocortins. It is postulated that these proteins control the
biosynthesis of potent
mediators of inflammation such as prostaglandins and leukotrienes by
inhibiting the

release of their common precursor arachidonic acid. Arachidonic acid
is released from
membrane phospholipids by phospholipase A .
