Pronunciation: peg-AP-ta-nib SO-dee-um
Class: Selective vascular endothelial growth factor (VEGF) antagonist
- Injection 0.3 mg
Antagonizes effects of VEGF, which are thought to contribute to the progression of neovascular form of age-related macular degeneration.
C max approximately 80 ng/mL and occurs within 1 to 4 days after 3 mg monocular dose (10 × recommended dose). AUC about 25 mcg•hr/mL.
Radioactivity was mainly distributed in vitreous fluid, retina, and aqueous fluid 24 hr after intravitreous administration of a radiolabeled dose to both eyes of rabbits.
Following a 3 mg monocular dose (10 × recommended dose) plasma t ½ is about 10 days.
Indications and Usage
Treatment of neovascular (wet) age-related macular degeneration.
Ocular or periocular infections; standard considerations.

Category B .
Safety and efficacy not established.
Increases in IOP have been seen within 30 min of injection; therefore, monitor IOP and perfusion of the optic nerve head.
- Review administration regimen and importance of returning every 6 wk for additional therapy.
- Advise patient that medication will be prepared and administered by a health care provider in a health care setting.
- Caution patient that there is a risk of developing endophthalmitis for several days following the injection and to immediately seek care from an ophthalmologist if any symptoms consistent with development of endophthalmitis occur (eg, eye becomes red, sensitive to light, or painful; vision changes).
