Abstract:
Combinations of hydrophilic and hydrophobic entities in a biodegradable sustained release implant are shown to modulate each other's rate of release. Formulations of a therapeutically active agent and modulator provide substantially constant rate of release for an extended period of time.
Abstract:
Implants comprising active agents are employed for introduction into a suprachoroidal space or an avascular region of an eye for therapeutic purposes. The administration of drugs is controlled and maintained for long periods of time, while ensuring the substantial absence of significant levels outside the site of administration.
Abstract:
Intraocular administration of drugs such as alpha -2a interferon is employed in the treatment of age-related macular degeneration. Intraocular administration obviates the side effects associated with systemic administration, concentrates the drug at the site of the disease, and, where microcapsules are employed, provides continuous, long-lasting treatment.
