Abstract
Active ingredients such as medicines are mixed with excipient and then kneaded together with binder and solvent such as alcohol or water to prepare a wetted paste. A mold is filled with this paste. Top and bottom surfaces of the paste within the mold are coated with powder such as lubricant in order to avoid possible sticking of the paste to the apparatus during a subsequent compression step. Then a compressive pressure is exerted on the surface of the paste. Thereafter, the tablet is taken from the mold. The molded tablet can contain water-soluble or fat-soluble medicine.
