  • Publication number: 20250041425
    Abstract: Excipient granulations containing a viscosifying agent, a disintegrant, and one or more additional excipients are disclosed. An excipient granulation can be combined with a pharmaceutical granulation to provide a pharmaceutical composition. The excipient granulations can be used to increase the viscosity of an aqueous composition such as an oral pharmaceutical composition. When added to an aqueous solution, the excipient granulation can dissolve to provide a suspension of the pharmaceutical granules in a viscous solution. The excipient granulation can be used to improve the palatability of oral pharmaceutical compositions containing a pharmaceutical granulation.
