AI Technical Summary
Technical Problem
Existing robecoxib drugs require frequent administration in veterinary medicine to achieve a long-lasting analgesic effect, and have a short half-life in the body, affecting the convenience of use.
Method used
Robecoxib liposomes were prepared by encapsulating robecoxib in a phospholipid bilayer using liposome technology. By optimizing the ratio of phospholipids, cholesterol, and PEGylated phospholipids, and combining it with high-pressure homogenization technology, the encapsulation efficiency and drug loading of the drug were improved.
Benefits of technology
This improved the solubility and duration of action of robecoxib in vivo, reduced the frequency of administration, and enabled long-acting sustained-release drug delivery.
