Eye drops containing steroids and antibiotics are widely used to treat a large range of ocular diseases of the ocular surface. They require frequent instillation or a high dosage, which can affect quality of life. We developed a biomaterial from human umbilical cord that can be loaded with drugs before being placed in the inferior conjunctival fornix. In the present work, this viro-inactivated, freeze-dried, and sterile foam was loaded with dexamethasone phosphate. We studied the release kinetic of 100 mg of biomaterial loaded with 100 µg of dexamethasone phosphate. Assays have shown that the product can be loaded with 100 µg of dexamethasone and allows a progressive release over time for at least 48 h. In addition, when compared with the instillation of the same dexamethasone quantity (100 µg), instilled regularly via eye-drop solution at 0.79 mg/mL, the drug penetration through corneal tissues was better with the dexamethasone-loaded biomaterial.
