4.2 Drug Indication

For the treatment of pain and inflammation associated with cataract surgery.


FDA Label


Nevanac is indicated for:

- prevention and treatment of postoperative pain and inflammation associated with cataract surgery;

- reduction in the risk of postoperative macular oedema associated with cataract surgery in diabetic patients.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Low but quantifiable plasma concentrations of nepafenac and amfenac were observed in the majority of subjects 2 and 3 hours postdose, respectively, following bilateral topical ocular TID dosing of nepafenac ophthalmic suspension, 0.1%. The mean steady-state Cmax for nepafenac and for amfenac were 0.310 0.104 ng/ml and 0.422 0.121 ng/ml, respectively, following ocular administration.


5.2 MeSH Pharmacological Classification

Anti-Inflammatory Agents, Non-Steroidal

Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects. (See all compounds classified as Anti-Inflammatory Agents, Non-Steroidal.)

5.5 Absorption, Distribution and Excretion

Absorption

Nepafenac rapidly cross the cornea (6 times faster than diclofenac in vitro).


Route of Elimination

After oral administration of 14C-nepafenac to healthy volunteers, urinary excretion was found to be the major route of radioactivity elimination, accounting for approximately 85% of the dose, while fecal excretion represented approximately 6% of the dose. Nepafenac (prodrug) and amfenac (active compound) were not quantifiable in the urine.


5.6 Metabolism/Metabolites

Nepafenac (prodrug) is deaminated to amfenac (active compound) in the ciliary body epithelium, retina, and choroid by intraocular hydrolases. Subsequently, amfenac undergoes extensive metabolism to more polar metabolites involving hydroxylation of the aromatic ring leading to glucuronide conjugate formation.


5.7 Mechanism of Action

Nepafenac is a prodrug. After penetrating the cornea, nepafenac undergoes rapid bioactivation to amfenac, which is a potent NSAID that uniformly inhibits the COX1 and COX2 activity.
