The invention discloses water soluble medicament sustained-release tablets, which comprise the following components in part by weight: water soluble medicament 1-30, octadecanol 5-70, Eudragite L 100-55 2-50, talcpowder 2-30 and lactose 2-30. The water soluble medicament may be galanthamine hydrobromide, captopril, metoprolol tartaric acid or pseudoephedrine hydrochloride. In the invention, the octadecanol serving as a hydrophobic auxiliary material and the Eudragite L 100-55 sreving as a water soluble polymer auxiliary are adopted, so the release speed of the medicament can be controlled properly. The Eudragite L 100-55 is insoluble in gastric juice, but dissolves in duodenal juice to make high-viscosity sticky liquid, and thus the release and diffusion speed of the medicament can be reduced. The talcpowder which is a hydrophilic matter insoluble in water plays a porogen role in the sustained-release tablets. In the invention, the release speed of the medicament is regulated by regulating the mixing ratio of the medicament to the auxiliary material. Thus, the release speed of an active medicament is controlled.
