Abstract

A solid pharmaceutical preparation dissolved in oral cavity, comprising part containing an intraoral antiinflammatory ingredient of 45 sec to 2 min disintegration time, exhibited in a disintegration test according to the Japanese Pharmacopoeia disintegration test, and part containing an intraoral antimicrobial ingredient of > 3 min disintegration time. This solid pharmaceutical preparation enables to easily realize simultaneous accomplishment of treatment of throat pain and intraoral sustained sterilization by means of a single pharmaceutical preparation.

Description

technical field [0001] The present invention relates to a solid preparation for dissolving in the oral cavity, which can easily treat pains such as the throat and continuously sterilize the oral cavity simultaneously with a single preparation. Background technique [0002] With the OA of air-conditioning, public hazards such as air pollution, and environmental pollution of climate, water and soil, the number of patients complaining of sore throat is increasing. In general, a sore throat is treated by directly sterilizing the affected part from the outside, and by allowing the drug to enter the blood circulation to internally suppress the inflammation that causes the sore throat. For example, as a method of directly sterilizing an affected part from the outside, the mouth is gargled with a gargle containing a fungicide such as povidone iodine or cetylpyridinium chloride. Alternatively, a method such as dissolving a buccal tablet containing a bactericide in the mouth to steri...
