Example Embodiment

[0053] The dry granulation of embodiment 1 Dexibuprofen

[0054] (1) See Table 1 for dry granulation prescription.

[0055] Table 1. Dry granulation prescription (mg / tablet)

[0056] Raw materials

[0057] colloidal silica

[0058] (2) Preparation method

[0059] Mix Dexibuprofen, microcrystalline cellulose 102 and colloidal silicon dioxide, pass through a 26-mesh sieve, and then use a high-speed rotary tablet press (GZPK3045 high-speed rotary tablet press, 45 punches, Shanghai Tianxiang Jiantai Pharmaceutical Co., Ltd. Co., Ltd.) pressed flakes, and the flakes passed through a swing granulator (26 mesh screen) to obtain dry granules. See the process flow figure 1 .

[0060] (3) Results

[0061] There is no sticking and punching phenomenon in the process of pressing the thin sheet; in the obtained dry granules, the weight percentage of Dexibuprofen is 76.9%.

Abstract

The invention discloses a dexibuprofen sustained-release tablet and a preparation process thereof. According to the preparation process, colloidal silicon dioxide is used as an antiplastering aid, and dry granulation is carried out by using a high-speed rotary tablet press; the prepared dry granules are respectively mixed with auxiliaries in specific quick-release and sustained-release layers to press a dual-layer tablet which is the dexibuprofen sustained-release tablet. The preparation process can be used for effectively reducing the sticking phenomenon caused by temperature increase when tabletting is carried out for a long time, and has simple process and relatively high efficiency; and the prepared sustained-release tablet has high bioavailability and good stability.

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to a Dexibuprofen sustained-release tablet and a preparation process thereof. Background technique [0002] Mixed ibuprofen is composed of equal amounts of ibuprofen and ibuprofen. It has been used clinically as an anti-inflammatory and analgesic for 30 years and is considered to be the safest non-steroidal anti-inflammatory drug (NSAID) ), and is an over-the-counter drug. However, mixed ibuprofen still has a variety of side effects including gastrointestinal toxicity, water and sodium retention, decreased renal perfusion, and allergic reactions, with an incidence rate of 15% to 30%. For the development of safer NSAIDs, two drugs have been proposed: cyclooxygenase-2 inhibitors and pure steric counterparts of NSAIDs, especially dexibuprofen. In 1996, Dexibuprofen began to be widely used in the treatment of rheumatoid arthritis in Austria. experience, so it is quickly accepted and...
