Gliolan – 5-aminolevulinic acid hydrochloride uses, dose and side effects

}

30 mg / ml powder for oral solution
5-aminolevulinic acid hydrochloride

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.

Talk to your doctor or pharmacist before taking Gliolan.

  • For 24 hours after receiving this medicine , protect your eyes and skin from strong light (for example, direct sunlight or strong, focused indoor light).
  • If you have a heart condition or have had a heart condition in the past, tell your doctor. In this case, this medicine should be used with caution, as your blood pressure may drop.

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, especially medicines that can cause skin problems if the skin is exposed to strong light (for example certain types of medicines called antibiotics ), but also over-the-counter medicines (for such as hypericin or St. John’s wort extract ).

A case of severe sunburn lasting 5 days has been reported in a patient after taking this medicine and a hypericin extract. You should not take any such products for up to 2 weeks after taking Gliolan.

Within 24 hours of taking Gliolan, avoid any other medicines that may harm your liver.

3. How to take Gliolan

This medicine is a powder, which must first be mixed with drinking water before use. This is always done by a pharmacy staff or a nurse and not by yourself. The usual dose is 20 mg 5 ‑ ALA HCl per kilogram body weight. The pharmacy staff or nurse will calculate the exact dose you need and the amount of solution (in milliliters) you need to drink. You must drink the reconstituted solution 2-4 hours before anesthesia.

If the operation is postponed by more than 12 hours, the operation must be rebooked until the next day or later. An additional dose of this medicine can be taken 2-4 hours before anesthesia.

If you take more Gliolan than you should

If you take more Gliolan than you should, your doctor will decide on the necessary measures to avoid any problems, including adequate protection against strong light (for example, direct sunlight).

If you forget to take Gliolan

This medicine is given only once on the day of surgery, 2 – 4 hours before the start of anesthesia. If you forget to take this medicine during this time, you should not take it just before anesthesia starts. In that case, anesthesia and surgery must, if possible, be postponed for at least 2 hours.

If you have any further questions on the use of this product, ask your doctor or pharmacist.
