Triamcinolone acetonide is an adrenocortical steroid that inhibits accumulation of inflammatory cells at inflammation sites, phagocytosis, lysosomal enzyme release and synthesis, and release of mediators of inflammation.¹

Uses

Triamcinolone acetonide is a synthetic corticosteroid medication used topically to treat various skin conditions,to relieve the discomfort of mouth sores, and by injection into joints to treat various joint conditions.

Pharmacological mechanism

Triamcinolone acetone is a synthetic adrenocortical hormone that exerts powerful anti-inflammatory effects by inhibiting the function of inflammatory cells and reducing the release of inflammatory mediators. In addition, it can suppress the immune response and reduce the occurrence of allergic reactions.²
