Title: Method for treating chronic rhinitis by permeating gauze with antibiotics/antibacterial liquid preparation and squeezing it, followed by inserting it into nasal cavity.
Inventor: IMAI MASAKAZU
IPC: A61P11/02
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a reliable method for treating chronic rhinitis. SOLUTION: The method for securing treatment of infectious diseases in the nasal cavity comprises a step for permeating a gauze with antibiotics/antibacterial liquid preparation and squeezing it and a step for inserting it into the middle and inferior nasal meatuses with chronic rhinitis and leaving it therein for a period of time ranging from a few minutes to approximately two hours. The gauze permeated with the antibiotics/antibacterial preparation directly contacts with the target affected region of sore, lesion, abscesses or the like in the mucous membrane. The action of these drugs persists for a period of time ranging from a few minutes to approximately two hours by maintaining a drug concentration in the optimal state.  In addition, the gauze has the function of absorbing stains such as nasal mucus, pus, and blood on the affected region and also has the function of protecting the affected region. Since the treatment is confined within the target area, the onset of allergy is at low level and the allergy is capable of being treated over a long period. When this treatment is properly practiced, the therapy for infectious disease in the nasal cavity can effectively be carried out.
