The present invention relates to monolithic intravaginal rings comprising progesterone, methods of making, and uses thereof. The intravaginal rings comprise progesterone, a polysiloxane elastomer, and a pharmaceutically acceptable hydrocarbon or glycerol esters of a fatty acid.
摘要:
Methods and compositions are disclosed for the intravaginal or rectal delivery of selected serotonin reuptake inhibitors (SSRIs) to the systemic circulation. Such methods and compositions are useful in the treatment of depression, migraine headaches, chronic pain, psychoactive substance abuse disorders, pre-menstrual dysphoric disorder (PMDD) and obsessive compulsive disorders. The compositions may be formulated for the immediate release or controlled release of SSRIs over an extended period of time. A preferred SSRI is fluoxetine.
摘要:
The present invention is related to pharmaceutical compositions comprising prostanoid-receptor agonists, intravaginal dosage forms comprising the same, and methods of making and using the same. The present invention is also related to a controlled release pharmaceutical gel for vaginal administration, the pharmaceutical gel comprising: (a) misoprostol; (b) a cellulose derivative; and (c) a polyol; wherein the gel is a substantially nonaqueous gel, and wherein the gel forms a hydrogel when placed in a vaginal tract.
摘要:
The present invention relates to compositions containing unconjugated estrogens and methods of their use in the treatment of conditions associated with hypoestrogenism or reduced estrogen levels in females.
摘要:
The present invention is directed to a method of treating a condition associated with an overactive bladder, comprising administering to a female an intravaginal device, comprising: (a) an annular first matrix comprising a pocket and a pocket wall, wherein the pocket wall has a uniform thickness, and wherein the pocket wall encompasses the pocket; and (b) a second matrix comprising an anticholinergic agent located in the pocket.
摘要:
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.
摘要:
A novel and useful apparatus for delivering an anesthetic locally to the cervical region of a female is provided, wherein the apparatus comprises a ring having a surface and at least one depression on the surface. An anesthetic composition comprising an anesthetic agent and an excipient are placed within the at least one depression. The ring is comprised of a pharmaceutically acceptable inert material that is biocompatible. Furthermore, the ring is of sufficient size such that it can be inserted into the vaginal canal of a female. In the vaginal canal, the anesthetic agent is immediately released from the anesthetic composition and directly anesthetizes the cervical region.
