Abstract

The invention discloses an enteric coated tablet containing sertraline hydrochloride and a preparation method thereof. The tablet is prepared from a naked tablet and an enteric coating membrane, wherein the naked tablet is prepared by adding a filling agent, a disintegrating agent, an adhesive and a lubricant into the sertraline hydrochloride through direct tabletting. The weight gain of the enteric coating membrane is 2-4%, so that the enteric coating membrane is disabled to dissolve and release in a stomach to generate untoward effect, and can be quickly dissolved and released in duodenums,and therefore, drug therapeutic effect is guaranteed. Besides, in order to ensure the stability of the sertraline hydrochloride tablet in intestinal tract, the content of methacrylic acid copolymer inthe enteric coating membrane is increased, and the content of tween 80 is further reduced. The enteric coated tablet disclosed by the invention has the characteristics of good dissolution rate, highstability, good invivo absorption and small individual difference, and is lower in side effect. The enteric coated tablet also has the advantages of simple preparation process and suitability for industrial large-scale production.
