NEW Patent CD for Use of O desmethyl N mono desmethyl tramadol

Following is a sample of the information contained on this CD: BACKGROUND OF THE INVENTION This invention relates to the use of O-desmethyl-N-mono-desmethyl-tramadol for the production of pharmaceutical compositions for the treatment of pain and various related indications as well as pharmaceuticals comprising O-desmethyl-N-mono-desmethyl-tramadol. The treatment of pain conditions is of great importance in medicine. There is currently a world-wide need for additional pain therapy. The pressing requirement for a target-oriented treatment of pain conditions which is right for the patient which is to be understood as the successful and satisfactory treatment of pain for the patients is documented in the large number of scientific works which have recently and over the years appeared in the field of applied analgesics or on basic research on nociception. SUMMARY OF THE INVENTION The underlying object of the present invention was to provide a substance useful in the treatment of pain and also related indications, as well as pharmaceutical compositions for such treatment. It has now been found that O-desmethyl-N-mono-desmethyl-tramadol is useful in the treatment of pain and also related indications. One main aspect of the invention is therefore the use of O-desmethyl-N-mono-desmethyl-tramadol as a racemate, a mixture of its enantiomers or a single enantiomer in the form of its base or salts of physiologically acceptable acids for the production of a pharmaceutical composition for the treatment of pain. O-desmethyl-N-mono-desmethyl-tramadol (sometimes referred to as MS in the literature and in the following text) is known as one of the in vivo metabolites of Tramadol (1RS,2RS)-2[(dimethylamino)methyl]-1-(3-methoxyphenyl)cyclohexanol; Lintz et al. Arzneim.-Forsch./Drug Res. 31(11), 1932-1943, 1981). Tramadol assumes a special position amongst centrally acting analgesics. Since this active ingredient acts as a strong inhibitor of pain without the
