Abstract

The invention discloses a preparation method of ferrous sulfate enteric-coated dropping pills, which comprises the following steps: (1) preparation of pill cores (2) preparation of enteric film coating liquid; (3) coating to obtain sulfuric acid Ferrous enteric-coated drop pills. The ferrous sulfate enteric-coated dropping pills produced by the present invention have small weight difference, high roundness, long dissolution time limit and good appearance quality, and all meet the requirements of the 2010 edition of the Chinese Pharmacopoeia.

Description

technical field [0001] The invention belongs to the field of medicine preparation, and in particular relates to a preparation method of ferrous sulfate enteric-coated dripping pills. Background technique [0002] At present, iron is an essential trace element for the human body. The body is highly dependent on iron, and iron deficiency is a nutritional problem I often encounter. Iron deficiency is the most inevitable problem in both developed and developing countries. The amount of iron in the human body is not much, accounting for about 4 / 100,000 of the body weight, and the iron content in the adult body is about 3-5 grams. According to the chemical properties and the role of iron in the body, it is divided into functional iron and reserve iron. Although their storage methods and proportions are different, their functions in the body are generally the same. Among the trace elements, the body's demand for iron is Other elements are irreplaceable and also an indispensable ma...
