Excipient information presented when available (limited, particularly for generics); consult specific product labeling.
Solution, Intraocular [preservative free]:
Macugen: 0.3 mg (0.09 mL)
Brand Names: U.S.
- Ophthalmic Agent
- Vascular Endothelial Growth Factor (VEGF) Inhibitor
Pegaptanib is an apatamer, an oligonucleotide covalently bound to polyethylene glycol, which can adopt a three-dimensional shape and bind to vascular endothelial growth factor (VEGF). Pegaptanib binds to extracellular VEGF, selectively inhibiting VEGF from binding to its receptors and thereby suppressing neovascularization and slowing vision loss.
Slow systemic absorption following intravitreous injection
Metabolized by endo- and exonucleases

For ophthalmic intravitreal injection only. Attach a 30 gauge 1/2 inch needle to the medication syringe. Slowly depress plunger to expel excess air and medication (refer to product labeling for detailed instructions). Adequate anesthesia and a topical broad spectrum antibiotic should be administered prior to the procedure.

Concerns related to adverse effects:
• Endophthalmitis/retinal detachment: Intravitreous injections are associated with endophthalmitis. Proper aseptic injection techniques should be used and patients should be instructed to report any signs of infection (eg, eye pain or redness, photophobia, blurred vision) immediately. Retinal detachment and iatrogenic traumatic cataract have been reported.
• Hypersensitivity reactions: Rare hypersensitivity reactions (including anaphylaxis/anaphylactoid reactions and angioedema) have been associated with use, occurring within several hours of use; monitor closely. Equipment and appropriate personnel should be available for monitoring and treatment of anaphylaxis.
• Increased intraocular pressure: Intraocular pressure may increase within 30 minutes following intravitreal injection. Monitor intraocular pressure and optic nerve perfusion.
Thromboembolic events: Thromboembolic events (eg, nonfatal stroke/MI, vascular death) have been reported following intravitreal administration of other VEGF inhibitors.
• Concurrent administration in both eyes: Safety and efficacy for administration into both eyes concurrently have not been studied.
Intraocular pressure (within 30 minutes and during the week after injection); signs of infection/inflammation (for first week following injection); retinal perfusion, endophthalmitis, visual acuity
Pregnancy Risk Factor
Adverse events have not been observed in animal reproduction studies.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience floaters, dizziness, diarrhea, or nausea. Have patient report immediately to prescriber severe headache, vision changes, eye pain, severe eye irritation, difficult urination, dysuria, eyelid edema, eye redness, eye discharge, bleeding in eye, or sensitivity to light (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
