摘要:
Submicron size particles of pharmaceutical or other water-insoluble or poorly water-insoluble substances are prepared using a combination of one or more surface modifiers/surfactants such as polaxomers, poloxamines, polyoxyethylene sorbitan fatty acid esters and the like together with natural or synthetic phospholipids. Particles so produced have a volume weighted mean particle size at least one-half smaller than obtainable using a phospolipid alone. Compositions so prepared are resistant to particle size growth on storage.
摘要:
Particles of water insoluble biologically active compounds, particularly water-insoluble drugs, with an average size of 100 nm to about 300 nm, are prepared by dissolving the compound in a solution then spraying the solution into compressed gaz, liquid or supercritical fluid in the presence of appropriate surface modifiers.
摘要:
An oil-in-water emulsion composed of an aqueous phase and an oil phase which comprises a synthetic triglyceride in which is dissolved cyclosporin and phospholipid, and optionally free fatty acid or a salt thereof, provides a stable pharmaceutical composition.
摘要:
A method for treating diabetes mellitus by administering composition providing a gastrin/CCK receptor ligand, e.g. a gastrin, and an EGF receptor ligand, e.g. TGFα, in an amount sufficient to effect differentiation of pancreatic islet precursor cells to mature insulin-secreting cells. The composition can be administered systemically or expressed in situ by cells transgenically supplemented with one or both of a gastrin/CCK receptor ligand gene, e.g. a preprogastrin peptide precursor gene and an EGF receptor ligand gene, e.g. a TGFα gene.
摘要:
This invention relates to a method for administering systemically active agents including therapeutic agents through the skin or mucosal membranes of humans and animals in a transdermal device or formulation comprising topically administering with said systemic agent an effective amount of a membrane penetration enhancer having the structural formula wherein X may represent sulfur, oxygen or nitrogen; a and b may be 0 or 1, c may be 0, 1 or 2, except that when X is oxygen, a, b and c are 0, when X is nitrogen c is 0 and only one of a or b is 1, and when X is sulfur a and b are0; A is a branched or a straight chain, divalent aliphatic radical having from 0 to 2 double bonds; Rʹ is selected from the group consisting of H, a lower alkyl group having from 1 to 4 carbon atoms, phenyl, lower alkyl or halogen substituted phenyl, acetamido, halogen, piperidinyl, lower alkyl or halogen substituted piperidinyl, carbalkoxy, carboxamide, and alkanoyl; and R is hydrogen or a lower alkyl group having from 1 to 4 carbon atoms, wherein Rʺ is H or halogen, and salts, e.g. acid or quaternary derivatives, thereof. These compositions are useful in topical or transdermal applications of the physiologically-active agent.
摘要:
Methods of treating inflammation of the gastrointestinal tract and/or systemic or local inflammation by administering a steroid anti-inflammatory or a non-steroid anti-inflammatory drug in conjunction with polyunsaturated fatty acids or their derivatives and optionally also a pharmacologically active antioxidant and compositions for practicing these methods are described.
摘要:
An adjuvant for administration to a host animal to enhance immune response, comprising a polysaccharide-phospholipid conjugate, whose polysaccharide moiety may for example comprise a modified glucan, chitosan, or alginate polysaccharide, conjugated to a phospholipid. The adjuvant may be suitably formulated with an antigen to provide a therapeutic vaccine for a variety of disease states and/or physiological conditions.
摘要:
Formulations ofphospholipid-coated microdroplets of propofol devoid of fats and triglycerides provide chronic sedation over extended periods of time without fat overload. Being free of nutrients that support bacterial growth, these microdroplet formulations are bacteriosatic and bactericidal (e.g. self-sterilizing) and thus have extended shelf life.
