  • Process for preparing quick dissolving, high loading ribavirin compositions
    Publication number: 20030104050
    Abstract: A quick dissolving, high loading ribavirin composition which is essentially free of ribavirin polymorphic forms, said composition is prepared by a process comprising: (a) mixing ribavirin, at least one disintegrant and/or at least one filler to form an homogenous mixture; (b) granulating the mixture in the presence of water to form a granulation; (c) drying the granulation; and (d) mixing at least one disintegrant and/or at least one lubricant with the granulation to produce a ribavirin composition, wherein said ribavirin composition comprises at least 80 weight percent of ribavirin, based on the total weight of the composition. The ribavirin compositions prepared by the wet granulation process of the invention are free flowing and have adequate bulk density for processing into capsules. In addition, the ribavirin compositions contain at least 80 weight percent of ribavirin. Furthermore, the ribavirin compositions are substantially free of polymorphic forms of ribavirin, i.e.
