Debittered ranitidine preparation |
| abstract |
Ranitidine (i.e. N-(2(((-5-((dimethylamino)methyl)-2-furanyl)methyl)thio)ethyl)-N'-meth yl-2-nitro-1,1-ethenediamine) prepn. comprises a salt of ranitidine with a polycarboxylic acid. The ranitidine prepn. is pref. in an aq. soln. The prepn. contains an equiv. amt. of polycarboxylic acid carboxylate gps./mol. ranitidine. The polycarboxylic acid has a mol. wt. of ≥ 1000 Dalton, pref. a carboxyl equiv. wt. of 72-800 Dalton, and is esp. an alkali-soluble acrylic acid and/or methacrylic acid polymerisate or copolymerisate. The polymerisate or copolymerisate comprises 10-100 wt.% acrylic acid and/or methacrylic acid units and 90- wt.% lower alkyl acrylate and/or lower alkyl methacrylate units. |
