Abstract
Abstract According to the invention there is provided various methods of treating mammalian interstitial cystitis and/or urethral syndrome through the use of Nifedipine, a calcium channel antagonist which has been primarily used for the treatment of coronary artery spasms and hypertension. Specifically, the invention is directed to the adminstration of an therapeutically effective amount of Nifedipine to mammals suffering from interstitial cystitis and/or urethral syndrome. The Nifedipine may be administered in admixture with a pharmaceutically acceptable carrier in a unit dosage form. The route of administration is that deemed preferred by the attending physician, with oral administration being preferred.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
79 words
A method for treating interstitial cystitis comprising the steps of administering to a living subject exhibiting the pathological conditions asociated with interstitial cystitis produced by autonomic nerve-mediated ischemia of the bladder a sufficient amount of Nifedipine to interrupt the abnormal autonomic reflex loop affecting the subject's bladder vasculature, thereby reversing the ischemia, wherein the administered amount of Nifedipine is from about 10 to about 80 mg which is administered daily for a period of time greater than four weeks.
Claim 2
Independent Claim
79 words
A method for treating interstitial cystitis comprising the steps of administering to a living subject exhibiting the pathological conditions asociated with interstitial cystitis produced by autonomic nerve-mediated ischemia of the bladder a sufficient amount of Nifedipine to interrupt the abnormal autonomic reflex loop affecting the subject's bladder vasculature, thereby reversing the ischemia, wherein the administered amount of Nifedipine is from about 10 to about 80 mg which is administered daily for a period of time greater than four weeks.
Claim 3
Independent Claim
79 words
A method for treating urethral syndrome comprising the steps of administering to a living subject exhibiting the pathological conditions asociated with urethral syndrome produced by autonomic nerve-mediated ischemia of the urethra a sufficient amount of Nifedipine to interrupt the abnormal autonomic reflex loop affecting the subject's urethra vasculature, thereby reversing the ischemia, wherein the administered amount of Nifedipine is from about 10 to about 80 mg which is administered daily for a period of time greater than four weeks.
Claim 4
Independent Claim
79 words
A method for treating urethral syndrome comprising the steps of administering to a living subject exhibiting the pathological conditions asociated with urethral syndrome produced by autonomic nerve-mediated ischemia of the urethra a sufficient amount of Nifedipine to interrupt the abnormal autonomic reflex loop affecting the subject's urethra vasculature, thereby reversing the ischemia, wherein the administered amount of Nifedipine is from about 10 to about 80 mg which is administered daily for a period of time greater than four weeks.
