| abstract |
The present invention provides a suspension comprising aluminum hydroxide and magnesium hydroxide and a preparation method therefor. An aqueous suspension composition according to the present invention ensures an excellent settling rate by using mixed suspending agents with a particular composition, so that insoluble aluminum hydroxide and magnesium hydroxide do not settle easily, form no cakes, and are easily re-dispersed. The aqueous suspension composition having an excellent settling rate not only has physical stability but forms a uniform dispersion system, thereby ensuring reproducibility or validity of bioavailability. Furthermore, the aqueous suspension composition according to the present invention provides an excellent texture, thereby increasing the drug compliance of a patient. |
