Abstract
Drugs in the form of very fine highly porous aerogel particles are delivered to a patient via inhalation. The aerogel particles are either an aerogelized form of a pharmaceutical or deposited upon aerogel particles produced from a non-inorganic oxide carrier matrix material, e.g. a sugar or carbohydrate. The aerogel particles are readily dissolvable by the pulmonary surfactant present in the lungs of a mammal.
