✦ Synopsis

In this paper, we found that the change of sodium montmorillonite's (MT) concentration in the magnesium-aluminum-ferrum hydrotalcite-like compounds (Mg-Al-Fe-HTlc)/MT suspensions would greatly influence the thixotropic type of the suspensions. Specifically, the increase in the MT's concentration increases the viscosities (η) of the HTlc/MT suspensions with the same R value (the mass ratio of HTlc to MT was signed as R, e.g., R＝ m HTlc /m MT ), meaning that the structure strength of the HTlc/MT suspensions increases. With the variation of MT's concentration, the thixotropic type of the HTlc/MT suspensions changed accordingly, and the mechanism has been discussed in this paper.

A new approach of improving drug dissolution properties is described. This method exploits the property of a carrier owing to the hydrotalcite-type anionic clays (HTlc). HTlc is an inorganic layered solid that lodges anionic compounds among its layers. As HTlc dissolves at acidic pH values (pH < 4),
