This invention relates to a vitreous form of 8-[3-[N-[(E)-3-(6-acetamidopyridin-3-yl)acryloylglycyl]-N-methylamino]-2,6-dichlorobenzyloxy]-2-methylquinoline (FR173657). This vitreous form has good solid stability and, therefor, is useful for producing and supplying FR173657 products whose quality is stable enough to be suitable for medicines.

Vitreous form of known bradykinin antagonist

The invention relates to a vitreous form of the compound, FR 173657, having the structure of formula (I). This vitreous form has good solid stability and is therefore useful for producing and supplying FR 173657 products whose quality is stable enough to be suitable for medicine.

A pharmaceutical composition comprising a tricyclic compound (I) or its pharmaceutically acceptable salt, an oil substance, a surfactant, a hydrophilic substance, water, and optionally a pH control agent, with enhanced stability, absorbability and/or a low irritation potential, is provided.

Pharmaceutical composition

Provided is a medicinal composition having a very satisfactory drug release profile and a very satisfactory drug absorption profile after oral administration characterized by its comprising an insoluble drug and two or more surfactants, at least one of the surfactants having as dissolved therein the insoluble drug and the other surfactant or surfactants.

Two surfactant-containing medicinal composition

A method for preparing stable crystals of a salt of Ceftizoxime which comprises mixing an aqueous solution of a salt of Ceftizoxime and isopropyl alcohol and collecting the precipitating crystals. Crystals obtained in this manner are more stable than the crystals obtained from prior art methods involving mixed solvents of water and ethanol.
