Insufflations are meant for being blown into various body tracts or cavities. They are medicated dusting powders meant for introduction into the body cavities such as nose, throat, ears, and vagina with the help of an apparatus known as ‘insufflator’. It sprays the powder into a stream of finely divided particles all over the site of application. Insufflations are intended for local action alone. But the intranasal insufflations are designed to administer drugs into the systemic circulation through the nasal mucosa. These are used for administration of potent drugs. This method controls the dose level through metered valves. It also protects the product from external environment.
