Abstract: The present invention relates to a pharmaceutical composition for treating cancer. More specifically, it relates to a pharmaceutical composition for treating cancer: which comprises an ionic compound in which two compounds selected from ascorbic acid, dichloroacetic acid and lactate are combined with one metal ion; has better therapeutic effect by overlapping and complex disturbances of cancer cell metabolism because different compounds are simultaneously uptake into cancer cells and each acts through different mechanisms on cancer cells, compared to the conventional anticancer drugs focusing on one specific mutation or cancer cell growth signal; and can more effectively inhibit the proliferation, invasion and metastasis of cancer cells because it is less susceptible to drug.

The plurality of particles for release control comprise a core material containing methylphenidate and a polymer coating layer for release control formed on the core material. The plurality of particles for release control are divided into two or more groups based on the average thickness of the polymer coating layer for release control. The particle groups are identical in terms of the composition of the polymer in the polymer coating layer, but are different in terms of the average thickness of the coated layer. The pharmaceutical composition for release control according to the present invention may control the release pattern of methylphenidate contained in the core material as desired, and can be used as an oral formulation in a variety of forms such as orally disintegrating tablets, etc.

Abstract: A fast-melting pharmaceutical tablet comprises a porous, plastic substance, a water penetration enhancer and a binder. One or more drugs can be incorporated into the formulation at different stages of the process so as to afford a pharmaceutically active tablet. Methods of making the pharmaceutical tablet entail combining the porous, plastic material, the water penetration enhancing agent, and the binder so as to form highly plastic granules, which are compressed into tablets. The resulting tablets dissolve rapidly in the mouth and have good hardness with low brittleness. The tablets are particularly valuable to those who have difficulty swallowing conventional pills.
