Angiogenesis inhibition

Angiogenesis is inhibited by the local administration of a pharmaceutical preparation formed from the reaction of hyaluronic acid, carboxymethylcellulose and a carbodiimide. The preparation, which can be in the form of a film or a gel, is advantageously applied directly to the site of a tumor, such as a cancerous tumor, used in conjunction with other chemotherapeutic techniques, or used to treat a chronic inflammatory condition, such as rheumatoid arthritis, endometriosis, arteriosclerosis, intimal hyperplasia, proliferative retinopathy, and the like.
