3. The device of claim 2 wherein said coating is incorporated with said mucoadhesive composition or said composition is attached to said coating.
4. The device of claim 3 wherein said vaginal device is completely or partially coated with said fluid impermeable material.
5. The device of claim 4 wherein said vaginal device is coated with said fluid impermeable material partially at the proximal end.
6. The device of claim 4 wherein said coating comprising said composition is attached to said device and configured to make physical contact with the vaginal mucosa and cervix of the uterus.
7. The device of claim 6 wherein said coating is attached to said device permanently or removably as a cap, cup or strip.
8. The device of claim 7 wherein said cap, cup or strip is attached to said device permanently and wherein said mucoadhesive composition is formulated as a foam, film, suppository, tablet, capsule or capsule containing microparticle or nanoparticle and is attached or inserted into said cap, cup or strip.
9. The device of claim 7 wherein said cap, cup or strip is attached to said device permanently and wherein said mucoadhesive composition is formulated as a solution, powder, cream, lotion, microparticle, nanoparticle, emulsion, liposomal suspension fluid, a bioadhesive system or microemulsion and incorporated into said cap, cup or strip.
10. The device according to claim 3 wherein said mucoadhesive composition comprises from about 0.001 to about 15 mg/kg of body weight the anti-migraine or anti-nausea drug, from about 40 to about 95% of a lipophilic or hydrophilic carrier, from about 1.5 to about 15%, by weight, of the mucoadhesive agent, from about 2 to about 30%, by weight, of sorption promoter and additionally from about 5 to about 30% of a permeation enhancer.
