Abstract
Provided herein is a novel and useful device and method for locally delivering and controllably releasing oxybutynin in the cervical region of a female. A device of the invention comprises a ring comprising trifluoropropylmethyl/dimethyl siloxane elastomer. A pharmaceutical composition comprising oxybutynin and an excipient is placed within a bore located in the ring, wherein the bore runs from the surface of the ring into the ring. The ring has a sufficient size such that it can be inserted into the vaginal canal of a female. A cap comprising is placed over the bore at the surface of the ring in order to contain the pharmaceutical composition within the bore. When the ring is inserted into the vaginal canal, the trifluoropropylmethyl/dimethyl siloxane elastomer controllably releases and locally delivers a therapeutically effective amount of oxybutynin to the detrusor muscle to treat the female's urinary incontinence.
