摘要:
The present invention is to provide emulsion preparations for nasal administration containing calcitonins, which are safely and effectively administered, compared with the conventional calcitonin preparations. The emulsions are prepared by using a calcitonin as the active ingredient, an azacycloalkane derivative as the absorption promotor such as 1-[2-(decylthio)ethyl] azacyclopentan-2-one, and glycyrrhizic acid or its salt.
