Abstract

The present invention relates to an amiodarone hydrochloride dispersing tablet and its preparation method. The described amiodarone hydrochloride dispersing tablet contains 5-30% of amiodarone hydrochloride, the rest is auxiliary material. The described auxiliary material can be excipient, disintegrating agent, surfactant, adhesive, corrective and lubricating agent. Its preparation method adopts conventional tableting process.

Description

technical field [0001] The invention relates to an amiodarone hydrochloride dispersible tablet and a preparation method thereof, belonging to the field of pharmaceutical preparations. Background technique [0002] In recent years, there has been little progress in the treatment of antiarrhythmic drugs, and the only one worth mentioning may be amiodarone, which has been clinically used for more than 20 years. After the results of the Arrhythmia Suppression Test (CAST) were published in the United States in the early 1990s, people re-recognized and re-evaluated amiodarone. At present, amiodarone has become one of the main drugs for the clinical treatment of arrhythmia. [0003] Amiodarone was first synthesized by Labze laboratory in 1961. It was originally introduced as a coronary artery dilator. In the 1970s, Singh discovered its electrophysiological mechanism of action. In 1976, Rosenbaum took the lead in applying it to the treatment of antiarrhythmia. In his report, the...
