    摘要: Liposome compositions in which a drug is retained in stable condition are prepared by dispersing liposomes obtained by removal of a solvent from a drug-containing w/o emulsion in an aqueous solution having an osmotic pressure higher by at least 20 percent than the osmotic pressure of a solution used for entrapping the drug in said liposomes. This composition is conducive to a sustained therapeutic efficacy or a better delivery of the drug to a target organ.

    摘要: A liposome composition is obtained by using as constituent components of the liposome membrane a polyoxyethylene derivative represented by the general formula:X--O--(CH.sub.2 CH.sub.2 O).sub.n --Y (I)wherein X represents an alkanoyl group or an alkyl group, Y represents a residue of a compound having a negative charge, and n is an integer of 2 to 50, and a phospholipid. The liposome composition has good dispersibility, high drug-encapsulation property and high stability.

    摘要: A drug held or supported by an interface comprising a porous matrix is dissolved with a drug dissolution liquid containing a humectant, and the drug is transdermally delivered by iontophoresis. The humectant includes e.g. glycerin and other polyhydric alcohols, sugar alcohols, proline and other amino acids and acidic mucopolysaccharides. The concentration of the humectant may be about 1 to 50% by weight, and the concentration of proline or other amino acid or its salt may be about 1 to 30% by weight. The drug includes (1) a physiologically active peptide or protein with a molecular weight of 100 to 30,000 or (2) a nonpeptide physiologically active compound with a molecular weight of 100 to 1,000.

    摘要: A parenteral pharmaceutical preparation comprises a matrix containing a physiologically active peptide or protein and a polyglycerol diester of a saturated fatty acid, and the matrix is in a solid form at room temperature. The molecular weight of the physiologically active peptide or protein is 2,000 dalton or more. The saturated fatty acid includes fatty acids having about 16 to 30 carbon atoms such as palmitic acid, stearic acid, etc. The matrix may be in a pillar or granular form. The parenteral pharmaceutical preparation can be used as an injectable solid administered subcutaneously or intramuscularly (for example, a pellet or tablet for implantation), a suppository or the like, and can release the physiologically active peptide or protein sustainedly for a prolonged period of one week or more.
