Abstract: A sustained-release, oral pharmaceutical formulation of tramadol comprising a compound formed in situ of tramadol or a tramadol salt and a pharmaceutically acceptable acidic substance. The compound formed in situ has a desired water solubility. Also provided are methods of treatment using the pharmaceutical formulations. Method for preparing such formulations are also provided. The preparation method comprises repeatedly mixing tramadol or its salt with the acidic substance, and moistening the mixture and formulating the mixture under an energy input, such as heat or pressure. Optionally, drying, repeated granulating, extrudation and pelleting may also be included.

Abstract: An oral administration unit containing the active substances Tramadol and Diclofenac and/or physiologically acceptable salts thereof, in which both active substances are contained in the same administration unit as two separately formulated subunits.

Abstract: A process for producing an oral, controlled release preparation of tramadol or a physiologically compatible tramadol salt having a storage stable active substance release profile by coating the active substance preparation with an aqueous ethylcellulose dispersion which contains at least one physiologically compatible, lipophilic diester of a C6-C40 aliphatic or aromatic dicarboxylic acid and a C6-C8 aliphatic alcohol as plasticizer, and, during coating, drying the coating at conventional temperatures, with the result that a storage stable active substance release profile is obtained even without subsequent heat treatment. Optionally, in order to increase the active substance release profile without impairing the storage stability of the preparation, a heat treatment may be performed at temperatures of >35° C. until a desired, increased active substance release profile is achieved.
