Abstract

The invention discloses ketoprofen lansoprazole sustained-release pellets. The pellets comprise the following components in parts by weight: 30-50 parts of ketoprofen, 3-5 parts of lansoprazole, 60-100 parts of filler, 3-5 parts of retardant, and 0-2 parts of lubricant, wherein the filler is one or more of starch, saccharose, lactose and microcrystalline cellulose, the retardant is ethyl cellulose, and the lubricant is one or more of magnesium stearate, talcum powder and polyethylene glycol 6000. Compound sustained-release pellets prepared from ketoprofen and lansoprazole have the advantages of high bioavailability, small local irritation, uniform medicine absorption speed and the like; the sustained-release pellets are coated, so that the medicament stability can be improved, the bitter taste of the pellets can be effectively covered, and the compliance of patient administration can be strengthened; sustained-release pellet tablets or sustained-release pellet capsules which are further prepared from the sustained-release pellets or coated pellets are convenient to carry and take; ketoprofen lansoprazole sustained-release pellets prepared by adopting an extrusion spheronization method or centrifugal granulation method are simple in operation, easy to control quality, narrow in size distribution range, good in roundness and smooth in surface, and are suitable for further coating, subpackaging or preparing.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and relates to a sustained-release pellet, a preparation method of the sustained-release pellet, and coated pellets, sustained-release pellets and sustained-release pellets further prepared by using the sustained-release pellet. Micropill capsules. Background technique [0002] Pellets are spherical entities with a diameter of less than 2.5mm composed of drugs and excipients. They can be made into immediate-release, sustained-release or controlled-release pellets according to different needs. They are usually packed in bags, filled in hard capsules or made into tablets. take. In recent years, the development of micropills has attracted widespread attention, and more and more varieties are on the market. Its main features are: (1) The distribution area of ​​the drug on the surface of the gastrointestinal tract increases, and the therapeutic concentration can be quickly reached...
