4.2 Drug Indication

Treatment of actinic keratosis of mild to moderate severity on the face and scalp (Olsen grade 1 to 2; see section 5. 1) and of field cancer ization in adults.

Treatment of superficial and/or nodular basal cell carcinoma unsuitable for surgical treatment due to possible treatment-related morbidity and/or poor cosmetic outcome in adults.


Gliolan is indicated in adult patients for visualisation of malignant tissue during surgery for malignant glioma (World Health Organization grade III and IV).


5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Photosensitizing Agents

Drugs that are pharmacologically inactive but when exposed to ultraviolet radiation or sunlight are converted to their active metabolite to produce a beneficial reaction affecting the diseased tissue. These compounds can be administered topically or systemically and have been used therapeutically to treat psoriasis and various types of neoplasms. (See all compounds classified as Photosensitizing Agents.)
