mobic and ampiroxicam

The efficacy of the selective cyclooxygenase-2 (COX-2) inhibitor meloxicam for treatment of postoperative oral surgical pain was assessed in a randomized controlled trial. Patients undergoing unilateral mandibular 3rd molar extraction surgery were allocated to 3 groups, A, B and C. After oral premedication of meloxicam 10 mg in group A, ampiroxicam 27 mg in group B and placebo in group C, surgery was completed within 30 min under local anaesthesia using 2% lidocaine. For postoperative pain relief the patients were allowed to take oral loxoprofen (60 mg per tablet). Postoperative pain was evaluated at the clinic on the 1st, 7th and 14th postoperative day (POD) using a visual analogue scale (VAS), as was the number of loxoprofen tablets consumed, and the results were compared among the 3 groups with statistical significance of P<0.05. VAS scores on 1 POD were significantly lower in group A than in group C. Loxoprofen consumption on the day of surgery and 1 POD was significantly lower in group A than in group C (P<0.01). Total analgesic consumption was significantly lower in groups A and B than in group C (P<0.02). The COX-2 inhibitor, meloxicam 10 mg used for premedication reduced postoperative pain compared with control in oral surgery.

The aetiology for nonsteroidal anti-inflammatory drug (NSAID)-induced small intestinal injuries has not been well characterised.. To determine the risk factors of symptomatic NSAID-induced small intestinal injuries, including diaphragm disease.. Of the 1262 symptomatic patients who underwent videocapsule endoscopy and/or double-balloon enteroscopy, 156 consecutive patients were verified as having taken NSAIDs. Their CYP2C9*2, *3 and *13 single nucleotide polymorphisms (SNPs) were determined by allelic discrimination with Taqman 5'-nuclease assays.. Of the 156 NSAIDs users, 31 patients (20%) were diagnosed with NSAID-induced small intestinal injury. Multivariate analysis indicated that the presence of comorbidities and the use of oxicams (meloxicam, ampiroxicam and lornoxicam) or diclofenac were associated with an increased risk of NSAID-induced small intestinal injury (adjusted OR: 2.97, 95% CI: 1.05-8.41, P = 0.041 and adjusted OR: 7.05, 95% CI: 2.04-24.40, P = 0.002, respectively). The combination of aspirin and non-aspirin NSAID was more damaging than aspirin alone. Age, sex, concomitant use of proton pump inhibitors, indications for NSAIDs use, duration of NSAIDs use and CYP2C9*2, *3 and *13SNPs were unrelated. The use of meloxicam and CYP2C9*3SNPs were significantly associated with an increased risk for diaphragm disease (adjusted OR: 183.75, 95% CI: 21.34-1582.38; P < 0.0001 and adjusted OR: 12.94, 95% CI: 1.55-108.36, P = 0.018, respectively).. The use of specific NSAIDs and the factors interfering with NSAIDs metabolism might associate with small intestinal injury, especially with diaphragm disease.

A high-performance liquid chromatography-tandem mass spectrometry (LC/MS/MS) technique was developed for the simultaneous determination of five non-steroidal anti-inflammatory oxicam drugs (ampiroxicam, tenoxicam, piroxicam, meloxicam and lornoxicam) in human plasma. These five oxicam drugs and isoxicam (internal standard) were extracted from human plasma with an Oasis(®) MAX cartridge column and analysed on a Unison UK-C18 column (2.0 mm × 100 mm, 3 μm) with an acetonitrile:10mM formic ammonium buffer (pH 3.0) (50:50) mobile phase at 0.20 ml/min at 37°C. The analytes were detected using a tandem mass spectrometer, equipped with an electrospray ion source (ESI). The instrument was used in multiple-reaction-monitoring (MRM) mode. The extraction yields from a 200 μl human plasma sample (containing 10 ng of each drugs) with the Oasis(®) MAX cartridge column were 93.3-102.5%. The detection limits were 0.01-6.5 ng/ml (S/N=3). Our developed method is very useful for the simultaneous determination of five oxicam (non-steroidal anti-inflammatory) drugs in human plasma by LC/MS/MS.
