Abstract
A method for oral treatment of patients using different types of drugs that are not usually transported to circulation, if administered orally, is disclosed. Because the TC II-Cbl complex is stable to acid and proteolytic enzymes both outside and inside the intestinal absorptive cells, the method consists of oral administration of a drug bound to TC II-Cbl complex. In addition, the method can also be used for delivering Cbl to a large number of patients who do not absorb Cbl due to a variety of causes such as surgery of their stomach (ulcers) or of their terminal ileum (Crohn's disease).
