| Description | Ampiroxicam(CP65703) is a nonselective cyclooxygenase inhibitor uesd as anti-inflammatory drug.
Target: COX
Ampiroxicam is a non-steroidal anti-inflammatory drug. It is a prodrug of piroxicam. Ampiroxicam inhibits the stretching response in mice induced by phenylbenzoquinone (PBQ) with maximum protective effect (MPE) of 2 mg/kg. Ampiroxicam inhibits swelling in a dose-responsive manner in the rat foot edema (RFE) assay with ED50 of 28 mg/kg at single oral dose and 7.8 mg/kg at 5 daily oral dose. Ampiroxicam blocks primary and secondary lesion development in rat adjuvant arthritis with ED50 of 2.2 mg/kg and 0.5 mg/kg, respectively. Ampiroxicam (3.2 mg/kg) leads to a plasma concentration of 12 μg/mL at a Tmax of 2 hours for piroxicam derived from ampiroxicam in rats [1]. Ultraviolet-A (UVA)-irradiated 1% Ampiroxicam sensitized in guinea pigs shows positive reaction in the patch testing to UVA-irradiated 1% Ampiroxicam and 1% thiosalicylate (TOS). Concentration of Ampiroxicam is easily reduced by the increase in UVA irradiation doses, as compared with that of piroxicam [2]. References: | |||||

Differential property of antigenic characterization between piroxicam and ampiroxicam in contact hypersensitivity.[Pubmed:10850378]
Res Commun Mol Pathol Pharmacol. 1999;105(1-2):147-54.
Piroxicam (PXM; a non-steroidal anti-inflammatory drug) has been reported to induce photosensitivity. In our previous report, however, ultraviolet-A (UVA)-irradiated or non-irradiated PXM did not induce any reactions in the in vivo model of contact hypersensitivity, while positive patch testing was shown by Ampiroxicam (APX; a prodrug of PXM). The purpose of the present study was to clarify the influence of protein on the antigenicity of PXM using this model. Animals sensitized by UVA-irradiated 1% APX showed positive patch testing (open application) in UVA-irradiated 1% APX, while they were negative in challenge by UVA-irradiated PXM with or without 5% human serum albumin (HSA). Although animals sensitized by 1% thiosalicylate (TOS), which is thought to be an active hapten of PXM, were cross-reacted with UVA-irradiated 1% APX, they failed to react with UVA-irradiated 1% PXM with or without HSA. On the other hand, intra-dermal testing (intra-dermal application) in UVA-irradiated 0.1% PXM with 5% HSA was positive in animals sensitized by UVA-irradiated 1% APX, while 5% HSA alone, 0.1% PXM with 5% HSA and UVA-irradiated 0.1% PXM did not induce any reactions under this condition. Furthermore, concentration of PXM in the presence of HSA was reduced by UVA-irradiation in a time dependent manner, while the degradation of PXM was not observed in the absence of HSA. Finally, PXM almost disappeared at 120 min after the initiation of UVA-irradiation. The degradation of PXM irradiated by UVA was dependent on the concentration of HSA at the range of 0 to 4%. Hence, these results suggest that the presence of protein is necessary for the induction of the antigenic activity of PXM and the antigenic characterization of PXM is different from that of APX in contact hypersensitivity.
Antigenic characterization in ampiroxicam-induced photosensitivity using an in vivo model of contact hypersensitivity.[Pubmed:10527378]
J Dermatol Sci. 1999 Nov;21(3):170-5.
Ampiroxicam (APX), a prodrug of piroxicam (PXM), has been reported to induce photosensitivity. Antigenic characterization of these photosensitivities, however, is still insufficient. The purpose of the present study was to elucidate further mechanism of photosenstivity induced by APX and PXM using an in vivo model of contact hypersensitivity in guinea pigs. Animals sensitized with ultraviolet-A (UVA)-irradiated 1% APX showed positive reaction in the patch testing to UVA-irradiated 1% APX and 1% thiosalicylate (TOS), while they were negative in challenge with UVA-irradiated 1% PXM, non-irradiated APX and PXM, whereas none of UVA-irradiated or non-irradiated APX and PXM showed positive patch test reaction in animals sensitized with UVA-irradiated 1% PXM or control vehicles. Animals sensitized with 1% TOS were successfully challenged by 1% TOS and cross-reacted with UVA-irradiated 1% APX; however, they failed to react with UVA-irradiated PXM, non-irradiated APX and PXM. Indeed, the in vitro study revealed that the concentration of APX was easily reduced by the increase of UVA irradiation dose, as compared with that of PXM. Interestingly, absorption spectrum of UVA-irradiated APX was similar to that of TOS, which is thought to be an active hapten of PXM. In the present study, we succeeded in the development of a novel animal model reflecting the clinical observations. Furthermore, these results suggested that contact hypersensitivity induced by UVA-irradiated APX is developed by photoproducts of APX itself, but not by the biotransformation of APX to PXM.
Preoperative ampiroxicam reduces postoperative pain after hand surgery.[Pubmed:11469844]
J Hand Surg Br. 2001 Aug;26(4):377-9.
We performed a double blind randomised controlled study to assess whether the preoperative administration of Ampiroxicam reduced the level of postoperative pain in 120 patients who underwent surgery to a hand under brachial plexus block. We found that preoperative (pre-emptive) administration of Ampiroxicam significantly reduced the postoperative pain levels and the need for postoperative analgesia.
