์์ฉ ๊ธฐ์ : Betamethasone diffuses across cell membranes and binds to specific cytosolic **glucocorticoid receptors**. The receptor-ligand complex translocates to the nucleus, where it alters gene expression (transactivation and transrepression). โ **Inhibits phospholipase A2** (via lipocortin induction), blocking the release of arachidonic acid. โ **Decreases production of inflammatory mediators** (prostaglandins, leukotrienes, cytokines). โ **Suppresses immune system response** by reducing leukocyte migration and capillary permeability.

Overdose via topical ophthalmic administration is unlikely to cause acute life-threatening signs, but chronic overuse can lead to iatrogenic hyperadrenocorticism (Cushing's syndrome) and local ocular complications (glaucoma, corneal degeneration).
