Associated Conditions
Pharmacodynamics
Duxol Ophthalmic Emulsion 0.05% is a corticosteroid used as an anti-inflammatory steroidal drug used primarily in ocular surgery.
Mechanism of Action
Corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins (lipocortins). It is postulated that these proteins control the biosynthesis of potent mediators of infammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2.
Absorption
Duxol Ophthalmic Emulsion 0.05% penetrates the corneal epithelium rapidly and effectively. Low systemic absorption.
Route of Elimination
78.5% of radioactivity was excreted aftert 24 hours, and 99.5% by 7 days after a single dose of labeled difluprednate instilled in the right eyes of pigmented rabbits.
Toxicity
Preclinical pharmacokinetic and toxicity studies have established that difluprednate ophthalmic emulsion 0.05% given 4 times a day is not toxic to the eye.
