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.
