    摘要: Compositions and methods for vaginal, buccal or nasal transmucosal delivery of drugs and for cryoprotecting of cells and embryos. For cryoprotection, the composition consisting essentially consist of a non-ionizable glycol derivative. For transmucosal delivery, the compositions essentially consist of a non-ionizable glycol derivative in a combination with a pharmaceutically active agent. For transmucosal delivery, the non-ionizable glycol derivative may be further combined with a mucoadhesive agent and/or a penetration enhancer and/or lipophilic or hydrophilic carrier for adhesion to and transport through a mucosa. The compositions are particularly suitable for administration of drugs through a nasal, buccal and vaginal mucosa or for long-term preservation of cell or embryos.

    摘要: Devices, methods, and compositions for vaginal delivery of bisphosphonates. A targeted site delivery of bisphosphonates to the vagina using a medicated intravaginal device comprising a bisphosphonate composition formulated for transvaginal delivery. A method for treatment of osteoporosis and related bone and skeleton diseases, for prevention of bone breakdown and loss of bone mass and strength by intravaginal administration of bisphosphonates to the vagina and transvaginal delivery of bisphosphonates to the general circulation.

    摘要: pH modulated films and methods of their preparation. The film compositions include at least one component having a non-neutral pH when combined with water; and a pH modulated polymer system selected to reduce or prevent synerisis when combined with the non-neutral component in combination with aqueous media. The films demonstrate a non-self-aggregating uniform heterogeneity. Desirably, the films disintegrate in water and may be formed by a controlled drying process, extrusion process, or other process that maintains the required uniformity of the film.
