GEL PREPARATION CONTAINING POLYSTYRENE-SULFONATES

摘要

A gel preparation containing polystyrene-sulfonate for treating hyperpotassemia, wherein the grain size of the polystyrene-sulfonate is regulated within a range of at least 5 to 100 mu m and the viscosity thereof before gelling is controlled by adding thereto a thickener so that the polystyrene-sulfonate grains are homogeneously dispersed. Preferably, the preparation contains agents substitutable for water and thus the moisture content therein is lowered. Since the gel preparation imparts neither any disagreeable feel nor roughness due to the active ingredients at the administration in the oral cavity, it can be taken without resort to water. Moreover it has a small moisture content, which makes it easy to control water intake even in the case of patients under strict moisture intake regulation such as ones with renal insufficiency. Thus, the quality of lift of the patients can be considerably improved.
