FAT EMULSIONS FOR INHALATIONAL ADMINISTRATION

摘要

Preparations for inhalational administration adequate for the inhalational administration of drugs, in particular, hardly water soluble drugs. The above preparations are provided as optionally freeze-dried fat emulsions which are o/w type fat emulsions wherein fat emulsion particles containing an oily component, an emulsifier and a drug as the essential ingredients are dispersed in water, characterized in that the fat emulsion particles have an average particle diameter of from 5 to 100 nm. By using an appropriate inhalator, aerosol particles capable of arriving at pulmonary alveoluses can be easily formed from the inhalants and the particle diameter of the aerosol particles can be easily controlled.
