Problems solved by technology

[0014] The present inventor has carried out research to sevelamer carbonate, finds that in the prepared tablet, sevelamer carbonate is in storage process, and the amount of carbonate radical is reducing, affects the stability of sevelamer carbonate, simultaneously the carbonic acid sevelamer The short residence time of sevelamer in the gastrointestinal tract limits its ability to exert greater phosphorus-binding effects

Abstract

The invention relates to a preparation for quickly disintegrating fatty amine polymer salt, and particularly relates to a sevelamer carbonate tablet. The formula of the preparation comprises the following components: 400-800g of sevelamer carbonate, 40-80g of microcrystalline cellulose, 40-80g of sodium hydrogen carbonate, 10-20g of arginine, 10-20g of polylactic acid and 1-2g of magnesium stearate. The preparation method comprises the following steps: preparing the active component (sevelamer carbonate) and the auxiliary components for later use; uniformly mixing the sevelamer carbonate, the microcrystalline cellulose, the sodium hydrogen carbonate, the arginine and the polylactic acid; adding water, and uniformly mixing; granulating through a dry method; then adding the magnesium stearate, and uniformly mixing; and tabletting.

Description

technical field [0001] The invention relates to a pharmaceutical preparation, in particular to a fast disintegrating preparation of fatty amine polymer salt and a preparation method thereof. Background technique [0002] Fatty amine polymer salts, such as: sevelamer carbonate, sevelamer hydrochloride, colesevelam hydrochloride, colestipol hydrochloride, cholestyramine hydrochloride, because the structure contains fatty amine polymers, resulting in difficulty in absorption , formulations are particularly difficult to manufacture, so rapidly disintegrating formulations are an important option. [0003] However, while preparing the fast-disintegrating preparation, other problems followed one after another, such as stability, gastrointestinal tract effect, phosphate binding rate and other problems encountered when preparing the fast-disintegrating preparation of sevelamer carbonate. [0004] Sevelamer carbonate, a fatty amine polymer, English name: Sevelamer carbonate, structur...
