Abstract

It was established that the Canadian and the American product are different pharmaceutical formulations, displaying different physicochemical and biochemical properties. The investigation demonstrated, furthermore, that neither preparation can be considered as a palliative in cancer therapy on the basis of the biological rationale advanced by their manufacturers.
