Abstract
A composition and method for nasal administration of pharmaceuticals utilizes glycyrrhetinic acid as an absorption enhancer. The composition comprises an effective amount of the pharmaceutically active substance, glycyrrhetinic acid, in an amount effective for enhancing permeation of the active substance across the nasal membrane, and a basic salt of an amino acid as an adjuvant. The composition may be administered to the nasal cavity in the form of a spray by using an atomizer, nebulizer, spayer, dropper or other device which ensures contact of the composition with the nasal mucus membrane.
