Abstract

The invention relates to a pharmaceutical composition for relieving pelvic pain or infertility associated with uterine dysrhythmia. The composition includes a locally-administered anti-dysrhythmic treating agent and a bioadhesive extended-release carrier. The composition may be delivered in an extended release formulation that includes a bioadhesive, water-swellable, water-insoluble, cross-linked polycarboxylic acid polymer, such as polycarbophil. The treating agent may be a local anesthetic, such as lidocaine. The invention also relates to a method of treating or preventing pelvic pain, or treating or improving infertility, by inserting a mixture of an anti-dysrhythmic treating agent and a bioadhesive carrier into the vagina of the patient to be treated.

Claims

6. The composition of claim 2, wherein the treating agent comprises lidocaine.

7. The composition of claim 5, wherein the treating agent is lidocaine at a concentration of about 2% to 10% by weight.

8. The composition of claim 5, wherein the composition is prepared so that a single dosage of about 1 to 1.5 g of the composition will release about 20 to 150 mg of lidocaine over at least about 24 hours after administration.

9. The composition of claim 8, wherein the composition is prepared so that a single dosage will release the treating agent over at least about 48 to 72 hours.

10. A pharmaceutical vaginal composition for treating or preventing pelvic pain, or for treating or improving infertility, associated with uterine dysrhythmia comprising a therapeutically effective amount of a local anesthetic treating agent and a pharmaceutically acceptable extended-release bioadhesive carrier.
