Abstract
Active and excipient ingredients were granulated in planetary and high intensity mixers. Compression properties of single and multi-drug formulations were evaluated with an insturmented single punch tablet press interfaced with a digitial computer. Dissolution rates were measured using the USP Apparatus #I. Binding efficiency was found directly proportional to granule coarseness for equally well-lubricated granulations. Some differences were observed between the starches, in the manner of their incorporation (dry or as slurry) and between the single and multi-drug formulations. The fromulations containing the pregelatinized starches allowed faster release of a poorly water soluble drug than did those containing starch, N.F.
