tilørerdose

Tilørerdose is a term used in some Scandinavian-language sources to describe the dose of a medicinal substance intended for administration to the ear, with the goal of achieving a local therapeutic effect while minimizing systemic exposure. The word is a portmanteau combining til (to), øre (ear), and dose. It is not widely standardized in major medical dictionaries, and its use is mostly encountered in regional or theoretical discussions rather than in formal pharmacology.

Definition and scope: A tilørerdose can refer to the quantity of drug delivered to the middle or inner ear, via routes such as intratympanic injection, ear drops, or other local delivery methods. Dosing considerations include the drug’s potency, formulation, diffusion through the tympanic membrane, ear canal volume, patient age, and disease process. Doses are often described in terms of volume (microliters) for suspensions or solutions, or mass (micrograms or milligrams) for solid or concentrated formulations.

Clinical context: Used in otology to treat conditions like otitis externa, otitis media, Menière's disease, or inflammatory conditions of the middle ear, and in some cases to administer corticosteroids or antibiotics directly to the ear. The approach aims to maximize local concentration while reducing systemic side effects.

Safety and regulation: Intratympanic or topical ear delivery carries risks such as tympanic membrane injury, ototoxicity, and inadvertent systemic absorption. Regulatory status of tilørerdose usage is variable and generally less standardized than systemic dosing.
