Abstract: Methods and materials useful for applying pharmacologic agents to the ear are described. The methods involve delivering a composition that contains at least one viscogenic agent and at least one pharmacologic agent to the epidermal surface of the tympanic membrane via the ear canal. The composition is delivered to the tympanic membrane in a flowable form and, after delivery to the tympanic membrane, becomes sufficiently viscous such that the pharmacologic agent is localized against the tympanic membrane. Such compositions can be used to prophylactically and/or therapeutically treat middle and inner ear conditions, including otitis media.

Abstract: A treatment for dry eye and other eye problems using a plug system or a delivery system. The plug system comprises solid, porous or hollow microcapsules composed of a biodegradable biocompatible polymer. The capsules are stored in the form of a powder that can be suspended in an aqueous carrier solution or dispersed in a gel or an ointment. Alternatively a biodegradable biocompatible capsule having a treating agent encapsulated within a polymer shell or a polymer sphere, again stored in the form of a powder that can be suspended in an aqueous carrier solution or dispersed in a gel or an ointment. The plug system prevents excretion of the capsules and their size is larger then the punctum and to prevent entrance to the lachrymal excretory system. The treatment is slowly released into the eye through the polymer shell or sphere and/or gets secreted as the polymer degrades.
