ABSTRACT:
A method and apparatus for storing, mixing and applying ALA as a treatment for lesions. The apparatus comprises a deformable container enclosing a hermetically sealed compartment of essentially anhydrous ALA which is shielded from exposure to air and moisture, and a liquid diluent. The liquid diluent may be in a second compartment. The deformable container is squeezed to crush the compartments and mix the essentially anhydrous ALA with the liquid diluent. The ALA may be delivered from the deformable container through a point applicator for controlling and precisely directing the application during treatment.
