Description
Technical field
The present invention relates to the new salt form of drug and preparation method more particularly to the new salt form of Vortioxetine-dihydroxy-benzoic acid and
Preparation method.
Background technology
According to statistics, the defects of drug candidate of about 70-80% is due to final physicochemical property, cause research and development failure and
It cannot finally list, so the physicochemical property for improving drug has a very important significance new drug development.Drug salt form exists
It is with the obvious advantage to improve drug solubility, dissolution rate, permeability, hygroscopicity, stability and bioavilability aspect.The new salt of drug
Type is that new eutectic substance (CCF) is introduced by proton translocation, under the active force of hydrogen bond with pharmaceutical activity active ingredient
(API) it is self-assembly of the supramolecular complex with fixed stoichiometric ratio.The development phase before clinical drug, new drug development are public
Pharmaceutical activity active ingredient (API) would generally be improved the solution degree, dissolution rate, infiltration of drug by department by way of into salt
Property, hygroscopicity, stability and bioavilability and some other physicochemical properties.When eutectic substance (CCF) is selected,
Drug is selected to be self-assembly of the effect of new salt form not only saves two kinds of drugs respectively as binding partner, and can significantly be changed
Solubility, dissolution rate and bioavilability of kind drug etc..Compared to nanocrystalline, solid dispersion and novel pharmaceutical formulation technology,
Drug salt form advantage in terms of improvement drug solubility, dissolution rate, permeability, hygroscopicity, stability and bioavilability is bright
It is aobvious, and the new salt form of drug succeeds in developing the patent barrier that can break new drug.
Vortioxetine is grown up by the treatment of Lundbeck drugmaker of Denmark and the joint research and development exploitation of Japanese Takeda Pharmaceutical Company Limited
The new drug of major depressive disorder, chemical name be 1- [2- (2,4- dimethyl benzene sulfenyl) phenyl] piperazine, molecular formula C18H22N2S。
