Verteporfin, sold under the trade name Visudyne among others, is a medication used to treat the wet form of age-related macular degeneration and choroidal neovascularisation due to severe short-sightedness.[1] It is given by injection into a vein followed by the use of a laser to activate it.[1][3] Both eyes may be treated following a single dose.[1]

Common side effects include pain at the site of injection and vision changes.[2] Other side effects may include shortness of breath, headache, tiredness, and fever.[3] It should not be used in those with acute porphyria.[3] It is a benzoporphyrin derivative.[2] Once activated it creates oxygen molecules in the area which block off excessive blood vessels.[1]

Verteporfin was approved for medical use in the Europe and the United States in 2000.[2][1] In the United Kingdom a vial of 15 mg costs the NHS about £850 as of 2021.[3] In the United States this amount costs about 1,800 USD.[4]

Medical use

Administration

a) The baseline photograph shows deep corneal neovascularization with lipid exudation involving the visual axis. b) 6 months after photodynamic therapy with verteporfin with reduction in the area of neovascularization and blood vessel size

Verteporfin is given intravenously, 15 minutes before laser treatment.[5]

It is given at a dose of 6 mg/m2.[3]

Contraindications

Porphyria.[5]

Side effects

Most common side effects are blurred vision, headache, and local effects at the injection site. Also, photosensitivity; it is strictly advised to avoid exposure to sunlight and unscreened lighting until 48 hours after verteporfin administration.[5]

Interactions

Verteporfin is known to interact with the herbal remedy feverfew (Tanacetum parthenium), the latter of which seems to act as an antagonist to verteporfin for unknown reasons. Taking the two substances simultaneously is inadvisable.[6]

Verteporfin does not appear to be metabolized by Cytochrome P450 enzymes, therefore not affecting Cytochrome P450 metabolism of other drugs.[7]

Research

Verteporfin is an inhibitor of fibrosis in patients with persistent cholestasis.[8] Verteporfin prevents fibrosis in several human organs.[8] In 2018 information revealed verteporfin stopped fibrosis in the lung.[8] Verteporfin is a marketed drug with a good safety profile. Verteporfin has also been used off-label.[9]

In 2021, scientists tested verteporfin to reveal if the drug would prevent scar tissue in skin.[10] Testing of verteporfin on humans cleft lips will occur in 2021.[11]
