摘要:
The invention relates to a Time-Controlled Explosion System in which drug release is caused by explosion of a membrane after a definite time period, said System comprising a preparation in the form of a bead or granule, said preparation comprising a core, a drug, swelling agent and an outer membrane of water-insoluble coating material.
摘要:
The invention concerns the preparation of a slow-release drug characterized by the coating of a core comprising a therapeutically active principle by means of a substance which retards its release and by means of an additional layer consisting of an enteric substance.
摘要:
The present invention is to provide a method for improving the dissolution of a poorly dispersible medicament and that is achieved by preparing a granulated product where a floating agent is added to the poorly dispersible medicament.

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.
摘要:
The present invention relates to fine particles of a poorly water-soluble drug wherein a predetermined enteric material is adsorbed as the dispersant on the surface of a poorly water-soluble drug, as well as a method for producing the same fine particles. It is possible to efficiently and safely produce in a short amount of time fine particles with which absorption of a poorly water-soluble drug that is poorly absorbed in humans, and the like can be improved, and a pharmaceutical preparation with excellent dispersion stability can be provided, by using the fine particles of the present invention having an improved dissolution profile.
摘要:
A stopper for a vial has a top portion and legs extending therefrom. The free or distal end of the legs have cut outs on each of the circumferential sides. The cut outs can be either straight or curved and are of such a size that the stopper can be securely held when partially fitted in a vial. The cut outs prevent the stoppers from becoming entangled during pre-treatment.
