Application Number:	16/796,494
Patent Claims:	1. A pharmaceutical composition for intranasal administration comprising: a citric acid salt of sumatriptan or a pharmaceutically acceptable solvate thereof, a pharmaceutically acceptable vehicle, and a mucosal permeation enhancer selected from the group consisting of 1-O-n-Dodecyl-.beta.-D-Maltopyranoside, tridecyl maltoside, sucrose monododecanoate, sucrose monotridecanoate, and sucrose monotetradecanoate, wherein upon said intranasal administration said pharmaceutical composition provides a T.sub.max substantially equivalent to subcutaneous administration of said sumatriptan. 2. The pharmaceutical composition of claim 1, wherein said mucosal permeation enhancer is present in a concentration of from about 0.05% to about 3.0%. 3. The pharmaceutical composition of claim 1, wherein said T.sub.max ranges from about 4 to about 15 minutes. 4. A method of treating cephalic pain or migraine in a subject in need thereof, said method comprising intranasally administering to said subject the pharmaceutical composition of claim 1. 5. The method of claim 4, wherein said T.sub.max ranges from about 4 to about 15 minutes. 6. A pharmaceutical composition comprising: an aqueous buffered solution comprising a citric acid salt of sumatriptan or a physiologically acceptable solvate thereof; and means for enhancing penetration of a drug via mucosal membrane and effecting a T.sub.max upon intranasal administration that is substantially equivalent to subcutaneous administration of the sumatriptan, wherein said means for enhancing penetration of a drug via mucosal membrane comprises alkyl glycoside or saccharide alkyl ester. 7. The pharmaceutical composition of claim 6, wherein said alkyl glycoside or saccharide alkyl ester is selected from 1-O-n-Dodecyl-.beta.-D-Maltopyranoside, tridecyl maltoside, sucrose monododecanoate, sucrose monotridecanoate, and sucrose monotetradecanoate. 8. The pharmaceutical composition of claim 6, wherein said alkyl glycoside or saccharide alkyl ester is present in a concentration of from about 0.05% to about 3.0%. 9. The pharmaceutical composition of claim 6, wherein said pharmaceutical composition provides T.sub.max value of less than 30 minutes upon intranasal administration. 10. The pharmaceutical composition of claim 6, wherein said pharmaceutical composition provides a T.sub.max value of less than about 30 minutes. 11. The pharmaceutical composition of claim 6, wherein said means for enhancing penetration of a drug via mucosal membrane is not a cyclodextrin.
