Title: | Pharmaceutical composition for treating dysmenorrhea and premature labor |
Abstract: | The present invention teaches a composition comprising a .beta.-adrenergic agonist in a bioadhesive carrier. Preferably, the composition comprises terbutaline in polycarbophil. The present invention additionally teaches the local administration of a .beta.-adrenergic agonist for the purpose of treating or preventing dysmenorrhea or premature labor. Using this composition and the method of treatment provides sufficient local levels of the drug to provide therapeutic efficacy, but avoids many untoward adverse events. |

Filing Date: | Sep 01, 1998 |
Application Number: | 09/145,172 |
Claims: | 1. A pharmaceutical composition comprising a therapeutically effective amount of a .beta.-adrenergic agonist together with a pharmaceutically acceptable bioadhesive carrier, wherein the bioadhesive carrier is a cross-linked water-insoluble but water-swellable polycarboxylic acid polymer. 2. The composition of claim 1 wherein the .beta.-adrenergic agonist is terbutaline. 3. A pharmaceutical composition comprising a therapeutically effective amount of a .beta.-adrenergic agonist together with a pharmaceutically acceptable bioadhesive carrier, wherein the .beta.-adrenergic agonist is terbutaline and the bioadhesive carrier is a cross-linked water insoluble but water swellable polycarboxylic acid polymer. 4. The composition of claim 3, wherein the concentration of terbutaline is from 0.1 to 0.4% weight/weight. 5. The composition of claim 4, wherein the polymer is polycarbophil. 6. The composition of claim 5, wherein the .beta.-adrenergic agonist is terbutaline and the composition is prepared so that a dosage of about 1 to 1.5 g of composition will deliver from 1 to 4 mg of terbutaline. 7. A method of preventing or treating dysmenorrhea comprising administering vaginally to a host in need thereof the pharmaceutical composition of claim 1. 8. The method of claim 7, wherein the .beta.-adrenergic agonist is terbutaline and the dosage of composition administered contains from 1 to 4 mg of terbutaline. 9. The method of claim 7, wherein the composition is administered every 12 to 48 hours during dysmenorrhea. 10. The method of claim 7, wherein the composition is administered every 12 to 48 hours beginning one day prior to the anticipated onset of dysmenorrhea and continuing during dysmenorrhea. 11. The method of claim 7, wherein the composition is administered every 24 hours during dysmenorrhea. 12. The method of claim 7, wherein the composition is administered every 24 hours beginning one day prior to the anticipated onset of dysmenorrhea and continuing during dysmenorrhea. 13. A pharmaceutical composition for vaginal administration of a treating agent to other than progesterone, achieve local efficacy without detrimental blood levels of the treating agent, comprising a therapeutically effective amount of said treating agent together with polycarbophil. 14. A method of delivering a treating agent, other than progesterone or an anti-sexually transmitted diseases agent, normally associated with potential undesired side effects at detrimental blood levels to a female subject comprising inserting a bioadhesive, cross-linked water-swellable but water-insoluble polycarboxylic acid polymer formulation with a therapeutically effective amount of said treating agent wherein the formulation releases the treating agent at a rate sufficient to achieve local efficacy without producing detrimental blood levels of the treating agent. 15. A pharmaceutical composition for vaginal administration of a treating agent during menses, comprising polycarbophil and a therapeutically effective amount of a treating agent. |
