摘要:
The invention relates to a pharmaceutical immediate release tablet comprising a core comprising 70-85 weight percent of sevelamer carbonate, calculated as an anhydrous compound, 10-25 weight percent of lactose monohydrate and, optionally, a water soluble film coat surrounding the to a process of making such tablets, to their use in medicine, and to the use of polyvinyl alcohol-polyethylene glycol graft copolymer for making such coated tablets.
摘要:
A pharmaceutical composition comprising raloxifene or a pharmaceutically acceptable salt thereof, a mixed cellulose excipient, and a disintegrant can be conveniently made.
摘要:
Controlled release tolterodine beads are formed of a sugar core, an innermost sealcoat layer comprising HPMC, a tolterodine drug layer, and an outer control release layer. The thickness of the hydrophilic HPMC sealcoat layer can be used help modulate the release of the tolterodine drug.
摘要:
The invention relates to an (S)-enriched citalopram tartrate compound, wherein at least 70% of the citalopram moieties are the (S)-enantiomer of citalopram.
摘要:
The invention relates to an S-zopiclone-L-tartrate compound, to a process, which comprises reacting a mixture of R- and S-zopiclone and/or a salt thereof with L-tartaric acid in a solvent to form a solution containing zopiclone ions and L-tartaric acid ions, to a process for increasing the enantiomeric purity of S-zopiclone, which comprises: (a) selectively precipitating from a solution, which contains zopiclone and tartaric acid as solutes and acetonitrile as a solvent, an S-zopiclone-L-tartrate acetonitrile solvate; and (b) treating said S-zopiclone-L-tartrate acetonitrile solvate with a base to form enriched S-zopiclone and to the use of L-tartaric acid in the making of enriched S-zopiclone and/or its L-tartrate compound.
摘要:
Crystalline aripiprazole Type II can be formed without solid state heat treatment. Instead a liquid is used such as in crystallizing from a solvent, especially 2-propanol, dimethyl sulfoxide, tetrahydrofuran or a combination thereof, or in a solvent mediated solid-solid transformation, typically in ethyl acetate.
