USPTO Abstract

A method for administering a therapeutically effective amount of a biologically active substance to the circulatory system of a mammal including administering a pharmaceutical composition having a total volume of 1-1000 mu 1 to a nasal mucosal membrane of the mammal, the pharmaceutical composition including the therapeutically effective amount of the biologically active substance dissolved or suspended in a volume of 1-1000 mu 1 of a n-glycofurol-containing vehicle including at least one n-glycofurol represented by the formula: <IMAGE> wherein n is from 1 to 8, so that upon administration of the pharmaceutical composition to the nasal mucosal membrane, absorption of the biologically active substance through the mucosal membrane and into the blood stream of the mammal rapidly takes place and thereby allows the biologically active substance to exert its therapeutic effect.
