Description

Technical Field

[0001] The utility model relates to the technical field of medicine preparation, in particular to a ketoprofen tablet pressing device. Background Art

[0002] Ketoprofen is a white crystalline powder, odorless or almost odorless, very soluble in methanol, soluble in ethanol, acetone or ether, almost insoluble in water, with a melting point of about 93-96°C. It is an aryl alkanoic acid compound with analgesic, anti-inflammatory and antipyretic effects. The anti-inflammatory effect is stronger than that of ibuprofen, with fewer side effects and low toxicity. It is easily absorbed from the gastrointestinal tract after oral administration. After a single dose, the peak plasma concentration can be reached in about 0.5-2 hours. The t 1 / 2 is 1.6-1.9 hours. It has a strong binding force with plasma proteins in the blood. The excretion rate in urine within 24 hours is 30%-90%, mainly excreted in the form of glucuronic acid conjugates. It is used for rheumatoid arthritis, rheumatic arthritis, osteoarthritis, ankylosing spondylitis and gout.

[0003] During the pharmaceutical production process, drug powder or granules are pressed into tablets for storage, sale and consumption. In the tableting process, a tablet press is one of the indispensable equipment, which can compress the original powder or granules through pressure to finally obtain drug tablets. After the tableting is completed, the existing tablet pressing device is easy to cause the tablet to be retained in the die hole, causing the tablet to stick to the inside of the die hole, affecting the quality of tableting and processing efficiency. On the other hand, the existing tablet pressing device is equipped with an ejection mechanism, but the ejection mechanism needs to be additionally equipped with a driving device for ejection, which is not only complex in structure but also not energy-efficient.
