The invention relates to the pharmaceutical preparation field and in particular to a
sodium dichlorophenolate micro-
pill pharmaceutical preparation and a preparation method thereof. The micro-
pill pharmaceutical preparation is prepared by micro-pills, which is characterized in that the micro-
pill is of enteric slow-release micro-pill, the micro-pill consists of a hollow pill core, an
active layer and an outer layer lagging cover, the
active layer comprises
sodium dichlorophenolate, a binding-property slow-release material and a binding-property enteric material, and the outer layer comprises a slow-release material. With the particular process and formula, a release
system thereof is made into a unique double slow-release
system, i.e. a skeleton-type scattering
system is combined with a multi-layer semi-penetration film lagging cover system, so the main
medicine can be continuously and stably released in the complicated internal environment of the
human body. In addition, by adopting unique auxiliary materials, the micro-pill is free from being dissolved in the
stomach and almost has no harm on the
gastric mucosa, the
medicine is ensured to have continuous effect of 24 hours inside the intestinal tract, the
bioavailability is improved, and the application effect of the
medicine is ensured.
