Treatment of gastrointestinal dysfunction and related stress with an enantiomerically-pure (S) 2,3-benzodiazepine
The present invention relates to methods of treatment for symptoms of gastrointestinal dysfunction and related stress that are frequently associated with, for example, irritable bowel syndrome. The symptoms include altered bowel motility, gastrointestinal inflammation, visceral hypersensitivity, or gastric ulcers.
1 . A method of treating or preventing irritable bowel syndrome, comprising administering to the individual an effective amount of enantiomerically-pure (S)-tofisopam; or a pharmaceutically-acceptable salt thereof.
2 . The method of claim 1 , wherein said (S)-tofisopam is administered with a second drug.
3 . The method of claim 1 for treating or preventing altered bowel motility associated with irritable bowel syndrome.
4 . The method of claim 3 , wherein said (S)-tofisopam is administered with a second drug.
5 . The method of claim 1 , for treating or preventing visceral hypersensitivity, pain, and bloating associated with irritable bowel syndrome.
6 . The method of claim 5 , wherein said (S)-tofisopam is administered with a second drug.
7 . The method of claim 3 , for treating or preventing gastrointestinal dysfunction related stress associated with irritable bowel syndrome.
8 . The method of claim 7 , wherein said (S)-tofisopam is administered with a second drug.
9 . The method of claim 7 , wherein said stress results in a gastric ulcer.
10 . The method of claim 9 , wherein said (S)-tofisopam is administered with a second drug.
11 . The method of claim 1 , wherein said (S)-tofisopam comprises 85% by weight or greater of the (S) enantiomer of tofisopam and 15% by weight or less of the (R) enantiomer of tofisopam.
12 . The method of claim 1 , wherein said (S)-tofisopam comprises 90% by weight or greater of the (S) enantiomer of tofisopam and 10% by weight or less of the (R) enantiomer of tofisopam.
13 . The method of claim 1 , wherein said (S)-tofisopam comprises 95% by weight or greater of the (S) enantiomer of tofisopam and 5% by weight or less of the (R) enantiomer of tofisopam.
14 . The method of claim 1 , wherein said (S)-tofisopam comprises 99% by weight or greater of the (S) enantiomer of tofisopam and 1% by weight or less of the (R) enantiomer of tofisopam.
