标题 (EN) SALTS OF N,N-DIMETHYLBIGUANIDE AND PREPARATION METHODS THEREOF
(FR) SELS DE N, N-DIMÉTHYLBIGUANIDE ET PROCÉDÉS DE PRÉPARATION ASSOCIÉS
摘要:
(EN) The present invention provides novel metformin salts, method of preparing, and pharmaceutical compositions containing the same. The metformin sesquihydrochloride and metformin dihydrochloride according to the present invention has improved pharmacological effects as compared with metformin monohydrochloride and is capable of achieving a therapeutic purpose by administering a reduced amount of metformin. The metformin sesquihydrochloride and dihydrochloride has excellent physicochemical properties, such as solubility, stability, non-hygroscopic and good flow characteristics.
(FR) La présente invention concerne de nouveaux sels de metformine, leur procédé de préparation et des compositions pharmaceutiques les contenant. Le sesquichlorhydrate de metformine et le dichlorhydrate de metformine selon la présente invention ont des effets pharmacologiques améliorés par rapport au monochlorhydrate de metformine et sont capables d'obtenir un effet thérapeutique par administration d'une quantité réduite de metformine. Le sesquichlorhydrate de metformine et le dichlorhydrate présentent d'excellentes propriétés physicochimiques, telles que la solubilité, la stabilité, une non-hygroscopicité et de bonnes caractéristiques d'écoulement.
