1. A method of intranasally administering a composition directly to a selected intranasal location of a human patient other than for effecting a block of the sphenopalatine ganglion, the method comprisingproviding a composition comprising a pharmaceutically active agent which is a pharmaceutically active agent other than a local anesthetic or which is a pharmaceutically active agent in combination with a local anesthetic, wherein the composition does not have only a local anesthetic as the only pharmaceutically active agent,inserting into a nostril of the patient an intranasal delivery device comprising a preformed body having a proximal end and a distal portion having a distal end, wherein the distal portion of the delivery device is curved or angled with respect to a longitudinal axis of the body, the longitudinal axis of the body at the distal end forming an angle of about 90 degrees to about 170 degrees with respect to the longitudinal axis at the proximal end prior to insertion of the distal end into a nasal cavity,urging the delivery device through the nostril such that the distal end is directed to the selected intranasal location, anddirecting the administration of the composition directly to the selected intranasal location via the delivery device by one ofcontacting the selected intranasal location by the composition on at least a portion of the distal end of the delivery device andby delivering the composition through at least one outlet port at the distal portion of the delivery device to which the composition is delivered through a lumen extending through the body to the selected intranasal location for causing the composition to selectively enter at least one of (i) the inferior boundary of the nasopharynx, (ii) sinuses via pathways specific thereto, and (iii) cerebral tissue selected from the group consisting of cerebral spinal fluid, a cerebral neuronal structure and cerebral vasculature, via pathways specific thereto.
