Problems solved by technology

Similar foreign products use surfactants as solubilizers to obtain a solution of meloxicam with a suitable concentration at a suitable pH, but in my country, there is no surfactant for injection, and the addition of surfactants—even if it is non-ionic Surfactants are also toxic and irritating to a certain extent, and may cause hemolysis, while cationic and anionic surfactants are more toxic, irritating and hemolytic, and are generally not used in injections and eye drops. The difficulty in the preparation of loxicam liquid preparations is how to obtain clear liquids of various doses of meloxicam that are suitable for clinical application and will not precipitate solids when stored at low or normal temperatures without the presence of surfactants.

Abstract

A liquid preparation of meloxican is prepared from the meloxicam or its medical salt and water-soluble cyclodextrin derivative HP-beta-CD used as solubilizer and stabilizer, proportionally mixing, adding cosolvent, pH regulator and water for injection, heating and membrane filtering. It has long storage time at low temp.

Description

Technical field: [0001] The invention relates to the technical field of medicine, in particular it is a meloxicam liquid preparation using HPCD as a solubilizer and a stabilizer and a preparation method thereof. Background technique: [0002] Meloxicam is a new generation of non-steroidal anti-inflammatory drugs developed by BOEDIRINGER INGELHEIM of Germany, and it is the first COX-2 inhibitor to be marketed. This product has significant and long-lasting anti-inflammatory effects and certain antipyretic and analgesic effects. Meloxicam, which is higher than the pharmacodynamic test dose, has no significant effect on the central nervous system, cardiovascular system, respiratory system, autonomic nervous system, etc. influences. Clinical trials have shown that the therapeutic effect of meloxicam on patients with osteoarthritis, rheumatoid arthritis, and sciatica is comparable to or even better than that of current NSAIDs, and the daily dose is better than that of piroxicam, ...
