Latest Patents

Among his latest patents, Rau has developed tablets with improved friability. These tablets are prepared using friability reducing agents, which make them more resistant to breakage or crumbling while maintaining satisfactory hardness. The agents include low molecular weight polyethylene glycol and similar compounds that exhibit at least three percent hydroxide moieties and a water solubility of at least eighty percent in room temperature water. The resulting tablets can incorporate an active agent and excipient of nearly any type, with a friability reducing agent concentration of about 0.1 to 0.5% by weight. These tablets demonstrate a hardness of at least eighty percent of those prepared without the friability reducing agent.

Another significant invention by Rau is the creation of effervescent tablets and granules. This innovation provides a solid form that dissolves in cold water quickly enough to satisfy consumers while retaining visual interest during the effervescent reaction. The effervescent particles are designed to be dense enough to slow down dissolution but small enough to dissolve within 30 to
