PHARMACEUTICAL FORMULATIONS COMPRISING THIOCOLCHICOSIDE
The present invention is related to pharmaceutical formulations comprising thiocolchicoside that shall be used in the treatment of trauma or neurologically-based cases with striated muscle tissue-related pains and spasticity and in degenerative spinal diseases such as torticollis, lombalgia, dorsalgia.
The molecule thiocolchicoside shown in formula I was first disclosed in the application numbered US2820029.
Formula I Thiocolchicoside is in forms of 4 mg/2 ml ampoule, combined gel, 4 mg and 8 mg capsule, 0.25% cream and pomade, 4 mg and 4 mg tablet.
It is seen that it takes long to dissolve for effervescent formulations comprising thiocolchicoside when put into water and some part of the formulation comprising the active agent remain undissolved in the glass. In this case, the sufficient active agent amount required for an effective treatment cannot be taken in the body. Since sufficient amount of the active agent thiocolchicoside is not taken in the body, absorption and thus bioavailability of thiocolchicoside decrease. In conclusion, low absorption and bioavailability of thiocolchicoside which are considered to be consequences of failure to take the sufficient amount of thiocolchicoside required for an effective treatment in the body cause decrease in efficiency and effectiveness of the treatment.
According to this, in line with the problems existing in the prior art, there is need for new approaches to develop effervescent formulations comprising thiocolchicoside which can easily be dissolved during use, can disperse in a short time, have high absorption and bioavailability and high therapeutic effect. The inventors have surprisingly seen that the effervescent formulations comprising thiocolchicoside and/or its pharmaceutically acceptable derivatives dissolve easily when put
into water during use, present faster dispersion in water and thus thiocolchicoside can provide an effective treatment in the case that said formulations comprise the effervescent acid at least at 30% in proportion to total tablet weight and the effervescent base at most at 50% in proportion to total tablet weight. Description of the Invention
The present invention relates to pharmaceutical formulations comprising thiocolchicoside, As a result of the studies they conducted in line with this need, the inventors have seen that the effervescent formulations comprising thiocolchicoside and/or its pharmaceutically acceptable derivatives dissolve easily, present faster dispersion in water and an effective treatment is enabled since thiocolchicoside presents high absorption and bioavailability in the case that said formulations comprise the effervescent acid at least at 30% in proportion to total tablet weight and the effervescent base at most at 50% in proportion to total tablet weight.
According to this, the first element of the present invention is the effervescent formulations comprising an effervescent acid at least at 30% in proportion to total tablet weight and an effervescent base at most at 50% in proportion to total tablet weight and thiocolchicoside as the active agent.
Thiocolchicoside used as the active agent in the formulations of the present invention is in the form of its solvates, hydrates, esters, enantiomers, racemates, organic salts, inorganic salts, polymorphs, crystalline and amorphous forms or free form and/or a combination thereof.
