1. What Gliolan is and what it is used for

Gliolan is used to visualize certain brain tumors (called malignant gliomas ) during a brain operation.

Gliolan contains a substance called aminolevulinic acid (5 ‑ ALA). 5 ‑ ALA accumulates mainly in tumor cells where it is converted to another similar substance. If the tumor is then illuminated with blue light, this new substance emits a red-violet light, which makes it easier to see what is normal tissue and what is tumor tissue. This makes it easier for the surgeon to remove the tumor while sparing normal, healthy tissue.

2. What you need to know before you take Gliolan

Do not take Gliolan

  • if you are allergic to 5 ‑ ALA or porphyrins
  • if you have known or suspected acute or chronic types of porphyria (ie hereditary or acquired disorders of certain enzymes in the synthesis of red blood pigments).
  • in case of known or suspected pregnancy.
