Triamcinolone acetonide (Azmacort) is a Corticosteroid. The mechanism of action of triamcinolone acetonide is as a Corticosteroid Hormone Receptor Agonist. It is an anti-inflammatory glucocorticoid used topically in the treatment of various skin disorders. Intralesional, intramuscular, and intra-articular injections are also administered under certain conditions.

在二次注射脂多糖的马中,Triamcinolone Acetonide减少水肿,跛行和关节液的蛋白浓度.在小鼠中,Triamcinolone Acetonide合成糖皮质激素,诱导腭发育不良导致的颚裂.在大鼠胚胎的颚中,Triamcinolone Acetonide对间质细胞增殖具有抑制,并影响MEE细胞分化成为复层鳞状上皮细胞.和单独的甲哌卡因相比,Triamcinolone Acetonide会使关节滑液中的白细胞计数和甲哌卡因浓度更高.

与空白组和IL-1组相比,Triamcinolone Acetonide降低聚糖合成,增加培养基中GAG含量。Triamcinolone Acetonide增加GAG降解。Triamcinolone Acetonide使ECV304细胞的细胞旁渗透性显著降低并使ICAM-1的表达下调,符合免疫细胞化学观察结果。在大鼠视网膜中,Triamcinolone使Müller胶质细胞渗透膨胀被逆转,这在多种实验条件下被观察到：在短暂视网膜缺血后第3天分离的视网膜,在1 mM Ba离子,10 μM 花生四烯酸,200 μM H2O2,或30 nM前列腺素E2存在的对照组视网膜,在用脂多糖诱导眼部炎症的视网膜。
