Methods for treatment of pelvic pain and/or comorbid conditions
Methods, systems, devices, and medicaments are provided for locally administering to a pelvic-area organ or tissue structure in a patient at least one drug continuously or continually over a treatment period of 24 hours or more in an amount effective to achieve a therapeutic effect in another organ or tissue structure by means of shared or convergent pelvic afferent pathways. The methods systems, devices, and medicaments can be used in the treatment of IC/BPS, chronic pelvic pain, vulvodynia, orchialgia, urethral syndrome, dysparenia, chronic prostatitis, chronic pelvic pain, levator ani syndrome, irritative bowel syndrome, or a combination thereof. The drug may include anesthetic agents, analgesic agents, antispasmodic agents, antimuscarinic agents, and combinations thereof. The drug may be released from a drug delivery device or a sustained release composition deployed inside the bladder.
1. A method of treating a patient, the method comprising:
locally administering lidocaine to a pelvic-area organ or tissue structure in the patient continuously or continually over a treatment period of from 2 to 28 days in an amount effective to achieve a therapeutic effect in another organ or tissue structure by means of shared or convergent pelvic afferent pathways,
wherein the lidocaine is administered at a mean average amount of from about 5 mg to about 30 mg lidocaine (FBE) per day, and
wherein the patient is diagnosed to have chronic pelvic pain, vulvodynia, orchialgia, urethral syndrome, dysparenia, chronic prostatitis, levator ani syndrome, irritative bowel syndrome, or a combination thereof.
2. The method of claim 1 , wherein the pelvic-area organ or tissue structure comprises the bladder.
3. The method of claim 1 , wherein the drug is released from a drug delivery device or a sustained release composition deployed inside the bladder.
4. A method of treating a patient, the method comprising:
diagnosing in a patient at least one of IC/BPS, chronic pelvic pain, vulvodynia, orchialgia, urethral syndrome, dysparenia, chronic prostatitis, levator ani syndrome, irritative bowel syndrome, and a combination thereof; and
administering locally to a pelvic-area organ or tissue structure in the patient at least one drug selected from the group consisting of anesthetic agents, analgesic agents, antispasmodic agents, antimuscarinic agents, and combinations thereof,
wherein the at least one drug is administered continuously over a treatment period of 24 hours or more in an amount effective to achieve a therapeutic effect which is sustained beyond the end of the treatment period; and
wherein the at least one drug comprises lidocaine and the lidocaine is administered continuously into the patient's bladder at a mean average amount of from about 5 mg to about 30 mg lidocaine (FBE) per day.
5. The method of claim 4 , wherein the pelvic-area organ or tissue structure comprises the bladder.
6. The method of claim 5 , wherein the drug is released from a drug delivery device or a sustained release composition deployed inside the bladder.
7. The method of claim 6 , wherein the drug comprises lidocaine.
8. The method of claim 4 , wherein the at least one drug provides a therapeutic effect in (i) the pelvic-area organ or tissue structure in which the at least one drug is administered, and (ii) at least one other organ or tissue of the pelvic area.
9. The method of claim 4 , wherein the at least one drug is an anesthetic agent or an analgesic agent and the anesthetic or analgesic agent does not provide a therapeutic effect in the pelvic-area organ or tissue structure in which the anesthetic or analgesic agent is administered, but does provide a therapeutic effect in at least one other organ or tissue of the pelvic area.
10. The method of claim 4 , wherein the therapeutic effect is provided by pelvic afferent neuronal crosstalk, cross-sensitization, or both.
11. The method of claim 4 , wherein the therapeutic effect comprises reducing pain.
12. A method of treating a patient diagnosed as having vulvodynia, orchialgia, urethral syndrome, dysparenia, chronic prostatitis, chronic pelvic pain, levator ani syndrome, irritative bowel syndrome, or a combination thereof, the method comprising:
administering lidocaine or another anesthetic agent into the bladder of the patient continuously or continually over a treatment period of 24 hours or more in an amount effective to achieve, by pelvic afferent neuronal crosstalk, cross-sensitization, or both, a therapeutic effect in a pelvic-area organ or tissue structure other than the bladder; and
wherein the lidocaine is administered continuously into the patient's bladder at a mean average amount of from about 5 mg to about 30 mg lidocaine (FBE) per day.
13. The method of claim 12 , wherein the lidocaine or another anesthetic agent is administered into the bladder by release from a drug delivery device or a sustained release composition deployed inside the bladder.
14. The method of claim 4 , wherein the treatment period is from 2 to 28 days.
15. The method of claim 4 , wherein the at least one drug comprises lidocaine and the cumulative amount of lidocaine (FBE) released into the bladder over the treatment period is from about 20 mg to about 400 mg.
16. The method of claim 15 , wherein the treatment period is from 2 to 28 days.
17. The method of claim 4 , wherein the drug is administered by continuous release from a device wholly deployed into the bladder of the patient during the treatment period.
18. The method of claim 12 , wherein the treatment period is from 2 to 28 days.
19. The method of claim 12 , wherein the lidocaine is administered continuously into the patient's bladder and the cumulative amount of lidocaine (FBE) released into the bladder over the treatment period is from about 20 mg to about 400 mg.
20. The method of claim 19 , wherein the treatment period is from 2 to 28 days.
21. The method of claim 12 , wherein the lidocaine or another anesthetic agent is administered by continuous release from a device wholly deployed into the bladder of the patient during the treatment period.
