Abstract

The invention discloses oxcarbazepine tablets and a preparation method thereof. The oxcarbazepine tablets comprise tablet cores and coating, wherein the tablet cores are obtained by directly pressing, and comprise the following components in percentage by weight in the oxcarbazepine tablets: 45 to 60 percent of oxcarbazepine, 5 to 10 percent of partially pregelatinized starch, 25 to 35 percent of starch and lactose compound, 3 to 7 percent of S-630 copovidone, 2 to 6 percent of cross-linked sodium carboxymethyl cellulose and 0.5 to 2.5 percent of sodium stearyl fumarate. By combining the characteristics that the oxcarbazepine is unstable in light and water, and is easy to deteriorate, the processes of adding water and drying are omitted in the preparation process of the oxcarbazepine, so that the production time is shortened, the production energy consumption is reduced, and manpower rand material resources are saved. The oxcarbazepine tablets disclosed by the invention have reasonable compositions, few impurities in a finished product, and obvious advantages of high dissolution rate and high tablet uniformity.

Description

technical field [0001] The invention relates to a tablet preparation of neurological drugs, in particular to an oxcarbazepine tablet and a preparation method thereof. Background technique [0002] Tablet refers to a disc-shaped or special-shaped tablet-shaped solid preparation that is uniformly mixed with a suitable excipient and compressed. Due to its advantages of accurate measurement, uniform content, good chemical stability, convenient use, and high degree of production mechanization, it has become one of the most widely used dosage forms at present. The preparation method of tablet comprises granulation tabletting method (specific process steps, see figure 1 ) and direct compression method (specific process steps, see figure 2 ), the granulation and tableting method is divided into wet granulation and tableting method and dry granulation and tableting method, and the direct compression method is divided into powder direct compression method and semi-dry granule table...
