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