preparation example Construction

[0039] The ferrous fumarate folic acid dispersible tablet of preferred embodiment, its preparation method comprises the following steps:

[0040] a, pulverization: respectively pulverize ferrous fumarate and folic acid into fine powder with a fineness of more than 120 mesh, and pulverize the pharmaceutically acceptable carrier into fine powder with a fineness of more than 100 mesh;

[0041] b. Granulation: Mix ferrous fumarate, folic acid, filler and internal disintegrating agent after step a is pulverized (surfactant can also be added), then add binder to make soft material, 18~ Granulate with 24 mesh sieve, dry at 45℃~55℃, pass through 20~24 mesh sieve for granulation;

[0042] c, tabletting: add lubricant and additional disintegrating agent (can also add flavoring agent) to the dry granule after step b granulation, mix evenly, tabletting, obtains ferrous fumarate folic acid dispersible tablet.

[0043] Because the dispersible tablet of the present invention has higher drug...

Abstract

The invention discloses a ferrous fumarate folic acid dispersible tablet and a preparation method thereof; the dispersible tablet is composed of 35-45 percent of composite of ferrous fumarate and folic acid and an acceptable carrier in pharmacy by mass percent; the mass ratio of ferric ions and folic acid in the composite of ferrous fumarate and folic acid is 150:1: the acceptable carrier in pharmacy comprises 30-60 percent of fillers, 2-10 percent of binding agents, 3-15 percent of disintegrants and 0.5-5 percent of lubricants by mass percent; the dispersible tablet is prepared by a wet granulation tabletting method and is rapidly disintegrated and evenly dispersed when meeting water, the effect is rapid, the bioavailability is high, and adverse reaction caused by overhigh local drug concentration of gastrointestinal tract can be alleviated or avoided, and the carrying and medicine taking are convenient; the preparation process is simple, the cost is low, the preparation is stable, safe and effective, thereby being suitable for industrial production.

Description

technical field [0001] The invention relates to a pharmaceutical preparation, in particular to a ferrous fumarate folic acid dispersible tablet and a preparation method of the ferrous fumarate folic acid dispersible tablet. Background technique [0002] Pregnant women are a special population with a high incidence of anemia. Studies have shown that women with anemia during pregnancy have a 5-fold increased risk of dying during pregnancy and childbirth, and are also more likely to have fetal malformations, premature birth and low birth weight. There are two main types of anemia that are most common during pregnancy: iron deficiency anemia and megaloblastic anemia. Iron deficiency anemia is hypochromic microcytic anemia in which hemoglobin synthesis is reduced due to iron deficiency in the body, and is the most common anemia during pregnancy. Pregnant women lose blood due to menstruation before pregnancy, resulting in insufficient iron storage in the body after pregnancy. Th...
