Compositions and methods for combating lower urinary tract dysfunctions with delta opioid receptor agonists
View Patent ↗Compositions and methods for treatment of a urinary tract dysfunction by administering to a subject in need of such treatment a pharmaceutical composition including a delta opioid receptor agonist in an amount effective to reduce the effects of the urinary tract dysfunction. The compositions may further include an additional active agent that is used to treat urinary tract dysfunctions, e.g., alpha-adrenergic agonists, anticholinergics, alpha-adrenergic antagonists and tricyclic antidepressants.
1. A method for combating a urinary tract dysfunction in a subject in need thereof comprising administering to the subject an effective amount of a delta opioid receptor agonist to combat the urinary tract dysfunction, wherein the delta opioid receptor agonist has the formula:
or a pharmaceutically acceptable salt or ester thereof, wherein the urinary tract dysfunction is urinary incontinence.
2. The method according to claim 1 , wherein the delta opioid receptor agonist is administered in a pharmaceutical composition comprising the delta opioid receptor agonist, or a pharmaceutically acceptable salt or ester thereof, and a pharmaceutically acceptable carrier.
3. The method according to claim 2 wherein the composition is administered by an administration modality selected from the group consisting of oral, rectal, vaginal, topical, sub-lingual, mucosal, nasal, ophthalmic, subcutaneous, intramuscular, intravenous, transdermal, spinal, intrathecal, intra-articular, intra-arterial, sub-arachnoid, bronchial, lymphatic, and intra-uterine administration.
4. The method according to claim 3 , wherein the composition is administered in a unitary dose form.
5. The method according to claim 1 , wherein the pharmaceutical composition for combating the urinary tract dysfunction, further comprises at least one additional active agent that combats the urinary tract dysfunction selected from the group consisting of phenylpropanolamine, pseudoephedrein, oxybutynin, propantheline, dicyclomine, tolterodine, prazosin, terazosin and doxazosin.
6. A method for reducing the effects of urinary tract dysfunctions in a subject in need thereof comprising: administering to the subject an effective amount of at least one delta opioid receptor agonist selected from the group consisting of:
and pharmaceutically acceptable salts and esters thereof, wherein the urinary tract dysfunction is urinary incontinence.
7. The method according to claim 6 , wherein the delta opioid receptor agonist is combined with a pharmaceutically acceptable carrier.
8. The method according to claim 6 , wherein the delta opioid receptor agonist is combined with an active agent used to treat urinary tract dysfunctions and is selected from the group consisting of: phenylpropanolamine, pseudoephedrein, oxybutynin, propantheline, dicyclomine, tolterodine, prazosin, terazosin and doxazosin.
