Abstract: The present invention relates to methods by which to produce sheet-like, wafer-like or film-like forms of drugs, confectionary, other food, cosmetics and the like for oral application or intake. The present invention is more particularly directed to the thermal treatment of carrier materials used in the production of such sheet-like, wafer-like or film-like forms. The thermal treatment removes contaminating or undesired substances from the carrier material.

Abstract: Disclosed is a pH-sensitive block copolymer obtained by copolymerization of: (a) a polyethylene glycol compound (A); and (b) at least one poly(amino acid) compound selected from the group consisting of a poly(?-amino ester) and poly(amido amine) or a copolymer thereof (B). A method for preparing the same block copolymer, and a polymer micelle type drug composition comprising the pH-sensitive block copolymer and a physiologically active substance that can be encapsulated with the block copolymer are also disclosed. The pH-sensitive block copolymer is obtained by polymerization of a hydrophilic polyethylene glycol compound with a pH-sensitive biodegradable poly(amino acid) compound. Therefore, the pH-sensitive block copolymer can form a micelle structure due to its amphiphilicity and ionization characteristics depending on pH variations, and thus can be used as drug carrier for target-directed drug delivery depending on pH variations in the body.

Abstract: Mixed micelles containing poly(L-histidine-co-phenylalanine)-poly(ethylene glycol) block copolymer and poly(L-lactic acid)-poly(ethylene glycol) block copolymer are a pH-sensitive drug carrier that release the drug in an acidic microenvironment, but not in the blood. Since the microenvironment of solid tumors is acidic, these mixed micelles are useful for treating cancer, including those cancers exhibiting multidrug resistance. Targeting ligands, such as folate, can also be attached to the mixed micelles for enhancing drug delivery into cells. Methods of treating a warm-blooded animal with such a drug are disclosed.
