A nasally administrable composition having a physiologically active substance dispersed homogeneously in and adsorbed homogeneously onto a unique carrier. The nasally administrable composition contains a physiologically effective amount of the physiologically active substance having a molecular weight of not more than 40,000, dispersed homogeneously in and adsorbed homogeneously onto physiologically acceptable powdery or crystalline polyvalence metal compound carrier. The metal compound carrier is selected from aluminum compound, calcium compound, magnesium compound, silicon compound, iron compound and zinc compound. The composition is nasally administrable in powdery form. |
