Abstract

The invention relates to the field of pharmaceutic preparations, in particular to a metoprolol tartrate tablet and a preparation method thereof. The provided metoprolol tartrate tablet is prepared from, by weight, 0.45-0.56 part of metoprolol tartrate, 0.2-0.4 part of lactose, 0.5-0.7 part of microcrystalline cellulose, 0.02-0.04 part of povidone K30, 0.06-0.12 part of sodium carboxymethyl starch,0.008-0.012 part of colloidal silicon dioxide and 0.016-0.024 part of magnesium stearate. The formula of an existing metoprolol tartrate tablet is optimized, and it is accidentally found that under the condition of not needing to add resin, surprisingly technical effects on overcoming sticky dissolution and dissolution rate are achieved.

Description

technical field [0001] The invention relates to pharmaceutical preparations, in particular to a metoprolol tartrate tablet and a preparation method thereof. Background technique [0002] Metoprolol tartrate is widely used clinically to treat hypertension, angina pectoris, myocardial infarction, hypertrophic cardiomyopathy, aortic dissection, arrhythmia, hyperthyroidism, cardiac neurosis, etc., and it is still used in the treatment of heart failure in recent years. treat. [0003] The solubility of metoprolol tartrate in water is very large, and the actual measurement can reach 1.5g / mL. However, most of the traditional wet granulation uses starch, dextrin or starch dextrin as the binder, which is dissolved in purified water and punched. Metoprolol granules are easily soluble and sticky, and the resulting granules have poor fluidity and are easily oxidized by moisture, which brings difficulties to granulation. Chinese application CN102716091A discloses a technical scheme for...
