Abstract

To solve the problem of an obvious side effect existing in the traditional Tripterygium Hypoglaucum Hutch root tablet, the invention provides a bi-layer extended release tablet which can reduce medicine peak plasma concentration. A Tripterygium Hypoglaucum Hutch root extract is any one extract of the whole Tripterygium Hypoglaucum Hutch root, Tripterygium Hypoglaucum Hutch root bark, or Tripterygium Hypoglaucum Hutch root core with the bark removed. The Tripterygium Hypoglaucum Hutch extract bi-layer extended release tablet has the characteristics of little untoward effect, and is convenient and safe to use. At the same time, a medicine-time curve is stable, the plasma concentration has small fluctuations, and the half life is prolonged. The Tripterygium Hypoglaucum Hutch root extract extended release bi-layer tablet using the root core with the bark removed has good therapeutic effects on asthma, lupus erythematosus, nephritis, and rheumatoid arthritis.
