Abstract: An enzyme in a mixture containing the enzyme and a contaminant enzyme is purified by selectively aggregating and precipitating the contaminant enzyme with a surfactant. A deacetylase contaminant is separated from Cephalosporin C acylase using a cationic surfactant in an amount of 0.1 to 0.6%. Surfactants include benzylated or methylated cationic surfactants such as alkyl(palm)dimethylbenzyl ammonium chloride, alkyl(palm)trimethyl ammonium chloride and dodecyltrimethyl ammonium chloride. An immobilized enzyme is regenerated using a protease to remove the enzyme from a carrier. The carrier may be a synthetic adsorbent or an ion exchange resin having pores of 100 nm or less in diameter, and the immobilized enzyme is optionally crosslinked. Immobilized cephalosporin C acylase is regenerated using an alkaline or acidic protease.

Abstract: This invention provides &bgr;-lactam antibiotic-containing tablets capable of being orally taken either as such owing to their being small-sized, hence still easily swallowable, or, in the case of administration to the aged encountering some difficulty in swallowing, in the form of dispersions resulting from easy self-disintegration upon being dropped into water in a glass as well as a method of producing the same. The tablets of this invention comprise, on the per-tablet basis, 60-85% by weight of a &bgr;-lactam antibiotic, 1-10% by weight of low-substituted hydroxypropylcellulose and/or crosslinked polyvinylpyrrolidone as a disintegrator, and 0.5-2% by weight of a binder. Granules to be compressed for tableting are prepared using water or an aqueous solution of ethanol or the like.

Abstract: To provide a pharmaceutical composition comprising a macrolide compound, such as tricyclic compound (I) or its pharmaceutically acceptable salt, a dissolution/absorption promoter, a pharmaceutical base, and optionally a compatibilizing agent and/or a thickener. It is satisfactory in stability and absorption kinetics and/or a low irritation potential.

Abstract: 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.

Abstract: Sustained release formulation containing tacrolimus or its hydrate is provided. The time (T63.2%) required for 63.2% of the maximum amount of tacrolimus or its hydrate to be dissolved is 0.7 to 15 hours. The time is measured in accordance to the Japanese Pharmacopoeia, the 13-th edition, Dissolution Test, No. 2 (Puddle method, 50 rpm) using an aqueous 0.005% hydroxypropyl cellulose solution. This aqueous test solution is adjusted to pH 4.5, accordingly. The formulation further comprise a solid base which is a water-soluble polymer and/or wax. The formulation is in the form of a powder, fine powder, granule, tablet or capsule. Furthermore, the formulation is administered to a patient once a day for preventing organ or tissue rejection by transplantation or autoimmune diseases.
