Methyl aminolevulinate (MAL) is a prodrug that is metabolised to Protoporphyrin IX (sensitizer) used in photodynamic therapy. 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 (Aktilite) to activate the photosensitiser.

Approvals and Indications

Approved in New Zealand for treatment of basal cell carcinoma[1].

It is now approved in many countries and has been used to treat non-melanoma skin cancer (including basal cell carcinoma)[2].
