Product Functions and Mechanism of Action
Fluocinolone Acetonide provides potent anti-inflammatory, antiallergic, and antipruritic effects. Its pharmacological actions include vasoconstriction and inhibition of epidermal proliferation. It stabilizes lysosomal membranes, reduces capillary permeability, decreases inflammatory exudation, and inhibits the release of histamine and other allergic and inflammatory mediators, thereby delivering strong anti-inflammatory and antipruritic effects.
Application Fields
1. Pharmaceutical API and Topical Dermatological Formulation Ingredient: Used as a raw material in creams, ointments, gels, medicated patches, and topical liniments. Suitable for formulations targeting non-infectious, thickened and pruritic skin conditions, including allergic dermatitis, chronic eczema, neurodermatitis, psoriasis, and prurigo nodularis.
2. Combination Formulations: Can be combined with antibiotics, borneol, vitamin B6, and other ingredients to develop compound ointment formulations.
