Abstract: An aqueous liposome system comprises at least one phospholipid, a non-phospholipidic substance which is a bile acid or derivative thereof, and, optionally, a non-toxic organic solvent. The mass ratio of phospholipid to the non-phospholidic substance is in the range between 1:0.001 and 1:0.1. The diameter of the liposomes formed in this liposome system is in the range between 35 and 90 nm. The liposome system is stable over large periods of time, e.g., several months or years, and is highly transparent. The liposomes may be loaded with a pharmaceutically active ingredient.

Abstract: A cyclooxygenase-2-inhibitor containing as an active ingredient a compound having cyclooxygenase-2-inhibitory activity and exhibiting low toxicity that causes only minor side effects. The active compound is represented by the following formula (1) or (1′): wherein R1 represents a hydrogen atom or a C1-C3 alkyl group; R2 represents a hydrogen atom, a hydroxyl group, an organic group capable of being bound through its thiol group within the molecule, or R1 and R2 may join to each other to form a single bond; R3 represents a hydrogen atom, a halogen atom, a C1-C3 alkyl group, a C1-C3 alkoxyl group, a trifluoromethyl group, or a nitro group; each of R4 and R5, which may be identical to or different from each other, represents a hydrogen atom, a halogen atom, a C1-C4 alkoxyl group, a trifluoromethyl group, or R4 and R5 may join to each other to form a methylenedioxy group.

Abstract: Liquid, active substance formulations containing an active substance insoluble or poorly soluble in water, or a mixture, a phospholipid, a special co-emulsifier (glycerinester in which the 1 or 2 OH groups have been esterized with hydrocarbon atoms of 8-16, preferably 8-10, C atoms by means of fatty acids and the 3 or remaining OH group of the glycerin body has been etherized with polyethyleneglycol, specifically, with 6-30, preferably 6-15 ethyleneoxide units) and a liquid carrier, the molar ratio of phospholipid to co-emulsifier being from 1:1 to 1:4, and the formulations being such that when added to water they form a transparent liquid system in the form of a microemulsion, with a degree of fineness of 10-200 nm in the lipid phase.

Abstract: A novel pharmaceutical composition is provided which is suitable for the prevention of inflammation and which comprises a non-steroidal inflammation-preventing compound (e.g. pyrazolones, salicyclic acid derivatives, indoles, indanes, and phenylacetic acid and anthranilic acid derivatives) and at least one phospholipid.

Abstract: The present invention is related to a process for filling pharmaceutical products which are highly viscous at room temperature, into hard capsules by admixing to such products a solvent or mixture of solvents in particular amounts, said solvent or solvent mixture having particular evaporation properties, and ejecting the resulting product from a usual filler nozzle under particular conditions, and closing the filled capsule with its cap.
