Abstract

The invention discloses a process for preparing Nicorandil tablets through charging diluent, binding agent, crumbling agent, lubricating agent, flow adjuvant and anti-oxidizing agent into 0.5-25.0 wt% of Nicorandil. The tablets can be prepared through direct powder pelleting method, dry method granulation pelleting or blank granulation method.

Description

Technical field [0001] The invention relates to a method for preparing a medicine, in particular to a method for producing nicorandil tablets by adopting a powder direct compression technique or a dry granulation technique or a blank granule method. The method can prevent the degradation of nicorandil under the influence of moisture and heat, and can improve the product quality and the safety of patients' medication. Background technique [0002] Nicorandil, also known as Yanlang Ding and Nicotinyl, is a nitrate compound. It is the only drug for the treatment of coronary heart disease and angina pectoris that has a dual mechanism of action among the cardiovascular drugs currently on the market. It not only has the effect of nitrate ester drugs to dilate coronary arteries, continuously increase coronary blood flow, inhibit coronary artery spasm, but also prevent the release of intracellular calcium ions and increase the permeability of cell membranes to pota...
