The present review is concerned with some essential formulative and therapeutic aspects of semisolid ophthalmic vehicles. The history and the most recent developments of the traditional lipophilic vehicles (ointments) are first outlined. The hydrophilic vehicles (hydrogels) based on synthetic polymers (polyacrylates, PEG, PVA, Pluronics, etc.), semisynthetic polymers (cellulose derivatives) and natural polymers (hyaluronic and polygalacturonic acid, alginates, etc.) are then examined. Some recent formulations of particular type are finally described.
