摘要:
A pharmacological agent-lipid solution preparation comprising a lipophilic pharmacological agent, a desalted charged lipid and an aqueous-miscible lipid solvent such that upon introduction into an aqueous medium a suspension of lipid aggregates associated with the pharmacological agent are formed, and methods of manufacture and use.
摘要:
Preparations of drugs in admixture with certain ligands are described which, when administered to animals or humans, are less toxic than conventional drug preparations. Although the toxicity of the drug-ligand preparations described is greatly reduced, the drug retains pharmacological activity.

摘要:
A new and substantially improved type of lipid vesicle, called stable plurilamellar vesicles (SPLVs), are described, as well as the process for making the same and X-ray diffraction methods for identifying the same. SPLVs are characterized by lipid bilayers enclosing aqueous compartments containing one or more entrapped solutes, the concentration of such solutes in each aqueous compartment being substantially equal to the concentration of solutes used to prepare the SPLVs. The bilayers of SPLVs are substantially non-compressed. SPLVs are stable during storage and can be used in vivo for the sustained release of compounds and in the treatment of disease.

SPLVs are characterized by lipid bilayers enclosing aqueous compartments containing one or more entrapped solutes, the concentration of such solutes in each aqueous compartment being substantially equal to the emunization of solutes used to prepare the SPLVs. The bilayers of SPLVs are substantially non-compressed. SPLVs are stable during storage and can be used in vivo for the sustained release of compounds and in the treatment of disease.

摘要:
Methods and compositions are described for the preparation of bioactive agents entrapped in lipid vesicles the bilayers of which comprise a salt form of an organic acid derivative of a sterol, such as the tris-salt form of a sterol hemisuccinate, and to compositions comprising a mixture of tris(hydroxymethyl)aminomethane salt of cholesteryl hemisuccinate with either an antifungal compound or a peptide. These compositions have various applications in vivo.

摘要:
Methods and compositions are described for the preparation of lipid vesicles, the bilayers of which comprise a salt form of an organic acid derivative of a sterol such as the tris-salt form of a sterol hemisuccinate. The method is rapid, efficient, and does not require the use of organic solvents. The sterol hemisuccinate vesicles may be used to entrap compounds which are insoluble in aqueous solutions. Such preparations are especially useful for entrapping bioactive agents of limited solubility thus enabling administration in vivo.
