Ampiroxicam
Based on 2 publication(s) in Google Scholar
Ampiroxicam is an orally active prodrug of non-steroidal anti-inflammatory drug (NSAID). Ampiroxicam inhibits paw swelling in adjuvant-induced arthritis and acute inflammation models, and suppresses phenylbenzoquinone-induced stretching responses in mice. Ampiroxicam is rapidly and completely converted to Piroxicam (HY-B0253) via non-specific esterases and first-pass metabolism. Ampiroxicam induces contact hypersensitivity and photosensitivity reactions through photoproducts generated by UVA. Ampiroxicam can be used in research related to photosensitivity, adjuvant-induced arthritis, rheumatism, osteoarthritis and other inflammatory diseases.
