Visualisation of malignant glioma

Active Ingredient: Aminolevulinic acid

Indication for Aminolevulinic acid

Population group: only adults (18 years old or older)
Therapeutic intent: Screening

5-aminolevulinic acid is indicated in adult for visualisation of malignant tissue during surgery for malignant glioma (WHO grade III and IV).

Dosage regimens

Oral, 20 milligrams aminolevulinic acid per kilogram of body weight, one dose.

Detailed description

The recommended dose is 20 mg 5-aminolevulinic acid hydrochloride (5-ALA HCl) per kilogram body weight.

Dosage considerations

The 5-ALA solution should be administered orally three hours (range 2-4 hours) before anaesthesia. Use of 5-ALA under conditions other than the ones used in the clinical trials entail an undetermined risk.

If the surgery is postponed by more than 12 hours, surgery should be re-scheduled for the next day or later. Another dose of this medicine can be taken 2–4 hours before anaesthesia.

Active ingredient

Aminolevulinic acid

5-Aminolevulinic acid (5-ALA) is a natural biochemical precursor of heme that is metabolised in a series of enzymatic reactions to fluorescent porphyrins, particularly PPIX. 5-ALA synthesis is regulated by an intracellular pool of free heme via a negative feedback mechanism. Administration of excess exogenous 5-ALA avoids the negative feedback control, and accumulation of PPIX occurs in target tissue. In the presence of visible light, fluorescence of PPIX (photodynamic effect) in certain target tissues can be used for photodynamic diagnosis.
