Triamcinolone acetonide binds to and activates the glucocorticoid receptor, leading to activation of anti-inflammatory transcription factors such as lipocortins and inhibition of inflammatory transduction pathways by blocking the release of arachidonic acid and preventing the synthesis of prostaglandins and leukotrienes.

Zilretta is not intended for repeat administration. It is available as a single-dose kit containing a vial of microsphere powder (32mg triamcinolone acetonide), diluent, and a vial adapter.
