Mechanism of Action

Betricin Ophthalmic Solution 0.1% works by mimicking the effects of cortisol, a natural hormone produced by the adrenal glands. It acts by binding to glucocorticoid receptors in the cytoplasm of target cells. This interaction modulates the expression of genes involved in inflammation and immune response, thereby reducing inflammation, swelling, and allergic reactions.
