Methyl aminolevulinate (MAL) is a drug used as a sensitizer in photodynamic therapy. It is a prodrug that is metabolized to protoporphyrin IX. It is marketed as Metvix.

Metvix cream is applied topically and some time later the skin is illuminated with a proprietary red light (630 nm) source (medical lamp 'Aktilite') to activate the photosensitiser.

Metvix is developed by Photocure and Galderma has bought all rights to Metvix.[1]

Approvals and indications

Methyl aminolevulinate is approved in New Zealand for treatment of basal cell carcinoma.[2]

It is now approved in many countries and has been used to treat non-melanoma skin cancer (including basal cell carcinoma).[3]

It has some advantages over Levulan.[4]

It has been reported as controversial in some quarters, with severe pain allegedly being experienced by some patients. [5]

  • Prior to treatment
  • One week after MAL PDT
  • One month after MAL PDT
  • Interim result of phototherapy for actinic keratosis with Metvix one week after exposure. Patient has light skin and blue eyes.
