Abstract

The invention discloses a tenoxicam tablet and a production process and application thereof. The tenoxicam tablet is prepared from tenoxicam, lactose, pregelatinized starch, hydroxypropylmethyl cellulose, carboxymethyl starch sodium, polysorbate-80, 15% starching pregelatinized starch, micro-powdered silica gel, magnesium stearate and a stomach dissolved type film coating premix. The production process comprises the steps of preparing a tablet core, coating and the like. According to the tenoxicam tablet, shown by treating 30 cases of rheumatoid arthritis, the anti-inflammatory and analgesic treatment effect is good, however, the influence on erythrocyte sedimentation rate is not great, and the total effective rate is 83%; the tenoxicam tablet has the characteristics that the number of medicine taking is small, the plasma concentration is stable, the duration is long and the like.
