Respecrin — A New Approach to Constructing Drugs with Targeted Action
The directed or targeted transport of drugs to sites of disease was first suggested by Ehrlich more than 100 years ago (Himmelweit, 1960). There is no doubt that drugs are most effective, and have fewest side effects, when their activity becomes manifest only upon contact with affected organs or cells. This is especially important in tumour therapy, where cytotoxic and highly antigenic protein factors are administered.
