12. Composition according to claim 9, characterized in that it is in the form of a gastroresistant tablet.

13. Process for the preparation of a tablet according to claim 1, which comprises the steps of: a) mixing SAMe, or salts thereof, with pharmaceutically acceptable excipients;b) pre-compression, followed by granulation, of the mixture obtained in step a);c) coating the granulated product obtained in step b) with hydrogenated fatty acids;d) mixing, pre-compression and granulation of the inositol and/or derivatives thereof with pharmaceutically acceptable excipients;e) coating of the granulated products obtained in step d) with hydrogenated fatty acids;f) mixing the granulated products obtained in steps c) and e) with pharmaceutically acceptable excipients;g) compressing the mixture obtained in step f) with the optional addition of sweeteners and aromas;h) optionally coating the tablets obtained in step g) with hydrogenated fatty acids;i) optionally film-coating in the aqueous phase the tablets obtained in step h).

14. Process according to claim 13, in which SAMe is S-adenosylmethionine para-toluenesulphonate.

15. Process according to claim 13, in which said inositol and/or derivatives thereof is inositol on its own, inositol 6-phosphate or a mixture thereof.

16. Process according to claim 13, in which the relative humidity is below about 25% and the temperature is maintained between about 20° C. and 30° C., in particular at about 25° C.

17. Process according to claim 13, in which in step d) it is possible to add, to the mixture, at least one other active component, preferably selected from St. John's Wort dry extract and lemon balm dry extract and/or mixtures thereof.

18. Process according to claim 13, in which the coating carried out in step h) is effected with hydrogenated fatty acids in an amount of between 0.5 and 2.5% by weight, relative to the weight of the composition.

19. Process according to claim 13, in which the film-coating in the aqueous phase carried out in step i) is effected with a varnish, preferably selected from rubber varnish and/or salts thereof (Shellac™), methacrylic acid, cellulose acetophthalates, titanium dioxide, talcum, triethyl citrate, PVP K30, riboflavin 6-phosphate, hydroxypropylcellulose, hydroxypropylmethyl-cellulose and/or mixtures thereof.

20. Process according to claim 19, in which the varnish is contained in an amount ranging from about 2.0 to about 8.0% by weight, relative to the composition.

21. Process according to claim 13, in which in step i) it is possible to optionally add lemon balm and/or St. John's Wort oil in an amount which varies from about 0.01 to about 0.2% by weight, relative to the total composition.

22. Dietary and/or nutraceutic pharmaceutical compositions obtainable by means of the process according to claim 1.

23. Use of SAMe, or salts thereof, in combination with inositol and/or derivatives thereof for the preparation of a composition for the treatment of depressive states and panic syndromes.

24. Use according to claim 23, in which said SAMe is S-adenosylmethionine para-toluenesulphonate.

25. Use according to claim 23, in which said inositol and/or derivatives thereof is inositol on its own, inositol 6-phosphate or a mixture thereof.

26. Method of stabilising a solid dietary and/or nutraceutic pharmaceutical composition based on SAMe or salts thereof, which comprises using inositol and/or derivatives thereof.

27. Method according to claim 26, in which the SAMe or salts thereof is contained in an amount of between about 10 and about 90% by weight, calculated relative to the weight of the composition.

28. Method according to claim 27, in which the SAMe or salts thereof is contained in an amount of between about 10 and about 50% by weight, calculated relative to the weight of the composition.

29. Method according to claim 26, in which the inositol and/or derivatives thereof is contained in an amount which varies from about 50 to about 90% by weight, relative to the weight of the composition.

30. Method according to claim 29, in which the inositol and/or derivatives thereof is contained in an amount which varies from about 50 to about 85% by weight, relative to the weight of the composition.
