    摘要: Described are modified release softgel capsules including a pH dependent shell composition that encapsulated a controlled release fill composition, methods of preparation thereof, and methods of use thereof. The pH dependent shell composition may be characterized in that the delayed release nature of the capsules may be achieved without a separate pH dependent coating or added conventional pH dependent polymers. The softgels provide a dual controlled release platform which facilitates delivery of the active agent to a target location in the gastrointestinal tract and a controlled release profile of the active agent at said target location in the gastrointestinal tract.

    摘要: The object of the present invention is to provide an absorption enhancer capable of introducing high-molecular weight compounds into cells.
    The object can be solved by a composition of the present invention comprising a polymer compound having a group represented by the following general formula (1) or the following general formula (2) at a side chain, and a compound to be administered with a molecular weight of 1,000 to 1,200,000.




    wherein X1 is a residue of neutral amino acid or ω-aminoalkanoic acid in which an end amino group and an end carboxyl group are removed, X2 is a residue of cell-penetrating peptide in which an end amino group and an end carboxyl group are removed, X3 is a hydroxyl group, an amino group, an alkoxyl group having 1 to 4 carbon atoms or a benzyloxy group, a is an integer of 0 to 50, and * denotes a bonding site.




    wherein X4 is a residue of neutral amino acid or ω-aminoalkanoic acid in which an end amino group and an end carboxyl group are removed, X5 is a residue of cell-penetrating peptide in which an end amino group and an end carboxyl group are removed, X6 is a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a benzyl group, an acyl group having 1 to 6 carbon atoms, an arylsulfonyl group or an oxycarbonyl group, b is an integer of 0 to 50, and * denotes a bonding site.
