  • Publication number: 20140205663
    Abstract: Dipeptidylpeptidase IV inhibitor (herein referred to as DPP-IV) that may be 98.5-100% pure is a high-dose drug capable of direct compressed with specific excipients into sold form dosage forms, such as tablets and capsules having desired, hardness, disintegrating ability and acceptable dissolution characteristics. DPP-IV is not inherently compressible and thus present formulation problems. Excipients used in the formulation enhance the flow and compaction properties of the drug and tableting mix. Optimal flow contributes to uniform die fill and weight control. The binder used ensures sufficient cohesive properties that allow DPP-IV to be compressed using the direct compression method. The tablets produced provide an acceptable in vitro dissolution profile.

  • Publication number: 20080280999
    Abstract: A process for making a solid oral dosage form that has a therapeutic compound (e.g., a poorly soluble and/or poorly compactible therapeutic compound) and a polymer. The process is accomplished by the use of an extruder. A transient plasticizer, e.g., a liquefied gas such as supercritical carbon dioxide, is added to facilitate processing of the materials. The transient plasticizer can serve to lower the viscosity of the mixture being processes and/or enhance the solubility of the therapeutic compound.

  • Publication number: 20080193529
    Abstract: Dipeptidylpeptidase IV inhibitor (herein referred to as DPP-IV) that may be 98.5-100% pure is a high-dose drug capable of being directly compressed with a glitazone and specific excipients into sold form dosage forms, such as tablets and capsules having desired, hardness, disintegrating ability and acceptable dissolution characteristics. DPP-IV is not inherently compressible and thus presents formulation problems. Excipients used in the formulation enhance the flow and compaction properties of the drug and tableting mix.
