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
Plasma: 10 ± 4 days
Use: Labeled Indications
Macular degeneration (neovascular age-related): Treatment of neovascular (wet) age-related macular degeneration (AMD)
Known hypersensitivity to pegaptanib or any component of the formulation; ocular or periocular infections
Macular degeneration (neovascular age-related): Intravitreous injection: 0.3 mg into affected eye once every 6 weeks
Refer to adult dosing.
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). Injection should be performed under aseptic conditions. Adequate anesthesia and a topical broad spectrum antibiotic should be administered prior to the procedure.
Store at 2°C to 8°C (36°F to 46°F); do not freeze. Do not shake vigorously.
Pegloticase: May diminish the therapeutic effect of PEGylated Drug Products. Monitor therapy
Pegvaliase: PEGylated Drug Products may enhance the adverse/toxic effect of Pegvaliase. Specifically, the risk of anaphylaxis or hypersensitivity reactions may be increased. Monitor therapy

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: 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.
Optic nerve head perfusion (immediately after injection), intraocular pressure (within 30 minutes and during the week after injection); signs of infection/inflammation (for first week following injection) or hypersensitivity; retinal perfusion, endophthalmitis, visual acuity
Pregnancy Risk Factor
Pegaptanib is a vascular endothelial growth factor (VEGF) inhibitor; VEGF is required to achieve and maintain normal pregnancies. Reports of intravitreal VEGF inhibitor use in pregnancy are limited and information specific to use of pegaptanib has not been located (Peracha 2016). Based on studies in nonpregnant adults, VEGF inhibitors can alter systemic concentrations of VEGF and placental growth factor following intravitreal administration (Peracha 2016; Zehtner 2015). Until additional information is available, intravitreal use during the first trimester should be avoided and use later in pregnancy should be based on patient specific risks versus benefits (Peracha 2016; Polizzi 2015).
Evaluate pregnancy status prior to use in females of reproductive potential. Based on information from other VEGF inhibitors, women of reproductive potential should use effective contraception prior to initial dose, during treatment, and for at least 3 months after the last intravitreal injection (Peracha 2016).
• 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.
