Biochem/physiol Actions

Nepafenac is a NSAID (nonsteroidal anti inflammatory drug) that is routinely used in opthamology to control pain following cataract surgery.
Nepafenac, a prodrug of amfenac, is used in the treatment of diabetic retinopathy. It is metabolized to its active form through intraocular enzymatic hydrolysis. Nepafenac has a molecular weight of 254.28 kDa and effectively penetrates through the cornea. Its molecule structure enables nepafenac to possess better permeability. Nepafenac has a low inhibitory effect on cyclooxygenase.

Nepafenac is a nonsteroidal anti-inflammatory drug (NSAID), currently only available as 0.1% ophthalmic suspension (Nevanac®). This study utilized hydroxypropyl-β-cyclodextrin (HPBCD) to increase the water solubility and trans-corneal permeation of nepafenac. The nepafenac-HPBCD complexation in the liquid and solid states were
