Abstract

See full text

The present invention relates to the delivery of rizatriptan or zolmitriptan through an inhalation route. Specifically, it relates to aerosols containing rizatriptan or zolmitriptan that are used in inhalation therapy. In a composition aspect of the present invention, the aerosol comprises particles comprising at least 5 percent by weight of rizatriptan or zolmitriptan. In a method aspect of the present invention, either rizatriptan or zolmitriptan is delivered to a mammal through an inhalation route. The method comprises: a) heating a composition, wherein the composition comprises at least 5 percent by weight of rizatriptan or zolmitriptan, to form a vapor; and, b) allowing the vapor to cool, thereby forming a condensation aerosol comprising particles, which is inhaled by the mammal. In a kit aspect of the present invention, a kit for delivering rizatriptan or zolmitriptan through an inhalation route to a mammal is provided which comprises: a) a composition comprising at least 5 percent by weight of rizatriptan or zolmitriptan; and, b) a device that forms a rizatriptan or zolmitriptan containing aerosol from the composition, for inhalation by the mammal.
