The present invention relates to the delivery of anti-migraine compounds through an inhalation route. Specifically, it relates to aerosols containing sumatriptan, frovatriptan, or naratriptan that are used in inhalation therapy. In a method aspect of the present invention, one of sumatriptan, frovatriptan, or naratriptan is administered to a patient through an inhalation route. The method comprises: a) heating a composition, comprising sumatriptan, frovatriptan, or naratriptan, to form a vapor; and, b) allowing the vapor to cool, thereby forming a condensation aerosol with less than 5% of the drug degradation products. In a kit aspect of the present invention, a kit for delivering sumatriptan, frovatriptan, or naratriptan through an inhalation route is provided which comprises: a) a thin coating of a sumatriptan, frovatriptan, or naratriptan composition; and, b) a device for dispending said thin coating as a condensation aerosol. |
