  • Patent number: 7429390
    Abstract: The present invention is generally related to alcohol free, liquid ranitidine formulations for oral administration. In particular, the present invention is related to stable, syrup formulations having ranitidine as an active ingredient for oral administration, processes for making the same, and methods of their use. The ranitidine of the present invention is stable in non-polar media or media having a relatively low polarity such that the dielectric constant is less than about 60, and is achieved by using certain saccharides, certain relatively high molecular weight starches, and/or certain celluloses instead of alcohol.
