Introduction
Difluprednate is a potent topical corticosteroid primarily used in ophthalmic formulations to treat inflammation and intraocular conditions. Its therapeutic efficacy and safety profile have positioned it as a critical component in ophthalmology. As demand grows, identifying reliable suppliers for difluprednate becomes essential for pharmaceutical companies, healthcare providers, and distributors seeking quality and consistent supply.
Overview of Difluprednate
Difluprednate is a synthetic fluorinated corticosteroid with a high affinity for glucocorticoid receptors, providing anti-inflammatory effects. It is marketed under various brand names such as Durezol, primarily by Alcon Laboratories.
