About Gleolan^® (aminolevulinic acid HCl)

Gleolan is an FDA-approved optical imaging agent indicated in patients with glioma [suspected World Health Organization (WHO) Grades III or IV on preoperative imaging] as an adjunct for the visualization of malignant tissue during surgery. Gleolan helps neurosurgeons see malignant tissue in real time during surgery and is provided orally (20mg/kg), 2-4 hours prior to glioma surgery. During the operation, the surgeon utilizes a surgical microscope with a specific blue light filter for the visualization of red-violet fluorescence.
