DESCRIPTION
Triamcinolone Acetonide Dental Paste USP, 0.1%, contains the
corticosteroid triamcinolone acetonide
in an adhesive vehicle suitable for application to oral tissues.
Triamcinolone acetonide is designated
chemically as 9-fluoro-11β, 16α, 17, 21-tetrahydroxypregna-1,
4-diene-3, 20-dione cyclic 16, 17-acetal
with acetone. The structural formula of triamcinolone acetonide is as
follows:
C
H FO MW 4 34 .50
Each gram of triamcinolone acetonide dental paste contains 1 mg
triamcinolone acetonide in an emollient
dental paste containing carboxymethylcellulose sodium, gelatin, and
pectin in a plasticized hydrocarbon
gel (a polyethylene and mineral oil gel base).
CLINICAL PHARMACOLOGY
Like other topical corticosteroids, triamcinolone acetonide 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 .
PHARMACOKINETICS
The extent of absorption through the oral mucosa is determined by
multiple factors including the
vehicle, the integrity of the mucosal barrier, the duration of
therapy, and the presence of inflammation
and/or other disease processes. Once absorbed through the mucous
membranes, the disposition of
corticosteroids is similar to that of systemically administered
corticosteroids. Corticosteroids are
bound to the plasma proteins in varying degrees. Corticosteroids are
metabolized primarily in the liver
and are then excreted by the ki
