  • Publication number: 20240115536
    Abstract: Solid oral dosage forms, especially tablets, of a pharmaceutical composition comprising a supramolecular complex can be formed from a direct compression process or a compaction process such as roller compaction. Such solid oral dosage forms feature an immediate release profile that allows for fast release of the therapeutic agent. A particularly useful supramolecular complex is trisodium [3-((1S,3R)-1-biphenyl-4-ylmethyl-3-ethoxycarbonyl-1-butylcarbamoyl) propionate-(S)-3?-methyl-2?-(pentanoyl{2?-(tetrazol-5-ylate)biphenyl-4?-ylmethyl}amino)butyrate]hemipentahydrate.

  • Publication number: 20060127479
    Abstract: A taste masked pharmaceutical composition comprising: (a) a core comprising a bitter tasting drug, such as cetirizine dihydrochloride; and (b) a coating comprising a pharmaceutically acceptable cationic co-polymer based on mono- or dialkylaminoalkyl methacrylate and neutral acrylic or methacrylic esters, wherein the alkyl group independently has 1 to 6 carbon atoms, wherein said coating is applied to the surface of said core. The taste masked pharmaceutical compositions of the invention may be prepared without using an organic solvent or a cyclodextrin.
