Aminolevulinic Acid

Aminolevulinic Acid

Aminolevulinic acid is a drug used in conjunction with photodynamic therapy to treat a wide variety of skin problems. This drug can also be used to help when doctors operate on gliomas on the brain or spine.

Aminolevulinic acid in the form of a gel is a photosensitizing agent. This drug will enter the abnormal skin cells and make the cells more sensitive to light from photodynamic therapy. When exposed to these rays, the cells that are entered by aminolevulinic acid will die.

Skin problems that can be treated with a combination of aminolevulinic acid and photodynamic therapy include actinic keratosis , warts, basal cell carcinoma, squamous cell carcinoma, acne, condyloma acuminata , and lichen planus .

Meanwhile, aminolevulinic acid in the form of an oral solution is an optical imaging agent . This drug works by making the glioma tissue appear to glow red, making it easy to detect and operate.
