Abstract:
Methods, devices, and compositions for treatment of dysmenorrhea comprise an intravaginal drug delivery system containing an appropriate pharmaceutical agent incorporated into a pharmaceutically acceptable carrier whereby the pharmaceutical agent is released into the vagina and absorbed through the vaginal mucosa to provide relief of dysmenorrhea. The drug delivery system can be a tampon device, vaginal ring, pessary, tablet, suppository, vaginal medicated tampon, vaginal sponge, bioadhesive tablet, bioadhesive microparticle, cream, lotion, foam, ointment, paste, solution or gel. The system delivers a higher concentration to the muscle of the uterus, the primary site for the dyskinetic muscle contraction, which is the pathophysiologic cause of dysmenorrhea.
