Abstract
Meloxicam, a non-steroidal anti-inflammatory drug, is used for the treatment of rheumatoid arthritis and osteoarthritis. Cytochrome P450 (CYP) 2C9 and CYP3A4 are major and minor enzymes involved in the metabolism of meloxicam. Impaired enzyme activity of CYP2C9 variants increases the plasma exposures of meloxicam and the risk of adverse events. The objective of our study is to develop and validate the physiologically based pharmacokinetic (PBPK) model of meloxicam related to CYP2C9 genetic polymorphism using the PK-Sim® software. In vitro kcat of CYP2C9 was optimized in different CYP2C9 genotypes. The demographic and pharmacokinetic dataset for the development of the PBPK model was extracted from two previous clinical pharmacokinetic studies. Thirty-one clinical datasets, representing different dose regimens and demographic characteristics, were utilized to validate the PBPK model. The shapes of simulated plasma concentration-time profiles in each CYP2C9 genotype were visually similar to observed profiles. The predicted exposures (AUCinf) of meloxicam in CYP2C9*1/*3, CYP2C9*1/*13, and CYP2C9*3/*3 genotypes were increased by 1.77-, 2.91-, and 8.35-fold compared to CYP2C9*1/*1 genotype, respectively. In all datasets for the development and validations, fold errors between predicted and observed pharmacokinetic parameters were within the two-fold error criteria. As a result, the PBPK model was appropriately established and properly described the pharmacokinetics of meloxicam in different CYP2C9 genotypes. This study is expected to contribute to reducing the risk of adverse events of meloxicam through optimization of meloxicam dosing in different CYP2C9 genotypes.

Abstract
Meloxicam is an enolate nonsteroidal anti-inflammatory agent. This trial investigated the pharmacokinetics, safety, and bioequivalence of single oral doses of Aomei meloxicam (15 mg) and Mobic meloxicam (15 mg) in healthy volunteers under fasting and fed conditions. A single-site, single-dose, randomized, open, 2-period, 2-sequence, crossover bioequivalence study was performed: 24 healthy volunteers were enrolled in each of the fasting and fed arms. Each HV was randomly assigned to receive the Aomei drug (test) in one period and the Mobic drug (reference) in the other period. The concentration of meloxicam in plasma was detected using liquid chromatography-tandem mass spectrometry. The primary pharmacokinetic parameters were calculated using a noncompartmental model. In the fasting arm, the 90% confidence interval of the geometric mean ratios of maximum plasma concentration, area under the concentration-time curve from time 0 to the last measurable plasma concentration, and area under the concentration-time curve from time 0 to infinity between the test and reference products were 99.5% to 111.7%, 101.2% to 106.8%, and 101.8% to 108.3%, respectively. In the fed arm, the 3 parameters were 94.1% to 102.4%, 97.6% to 103.0%, and 97.5% to 103.7%, respectively. These parameters were in the range of 80% to 125%, and the 2 products were considered bioequivalent in both the fasting and fed states and were well tolerated. The severity of all adverse events was mild. Aomei meloxicam tablets and Mobic meloxicam tablets were bioequivalent in healthy Chinese volunteers.

Abstract
OBJECTIVE The present study involved enhancement of Meloxicam (MX) oral absorption for rapid onset of therapeutic action. A challenging approach using hot-melt-extrusion technique (HME) for production of stable novel preparation of MX pellets was successfully proposed. METHODS Manipulating HME processing parameters (barrel-temperatures and screw-speed) and proper polymer(s) selection (Soluplus, a combination of Soluplus/Poloxamar and Polyethylene Glycol 6000) were the main strategies involved for productive extrusion of MX. Evaluation of MX solid-state (TGA, DSC and PLM), absolute percent crystallinity, in-vitro dissolution (in acidic/aqueous pHs), and stability testing in accelerated conditions up to 6-months as well as a long-term shelf for 36-months were performed. A comparative bioavailability study of selected MX-Pellets was carried-out against the innovator product (Mobic®) in 6 healthy volunteers under fed-conditions. RESULTS TGA, DSC and PLM analyses proved the dispersion of MX in amorphous-state within polymeric matrix by HME. MX/Soluplus pellets exhibited the lowest crystallinity % and best dissolution performance among other polymers in both pHs. In addition, presence of Soluplus safeguards final pellets stability under different storage conditions. MX rate of absorption (Tmax) from Soluplus-based pellets attained a value of 45 min, which was 6-times faster than Mobic® (4.5 hr). CONCLUSION A promising oral MX formula prepared by HME was successfully developed with a rapid onset of analgesic action (Tmax of 45 mins; almost 2-times faster than reported intramuscular injection), hence appropriate in the early relief of pain associated with rheumatoid arthritis and osteoarthritis. Moreover, the proposed formula was physico-chemically stable up to 36 months of shelf-life storage.

Abstract
PURPOSE The primary aim of the present study was to assess the pharmacokinetic bioequivalence between a generic formulation of meloxicam 15 mg tablets (Meloxicam Hexal) and its respective brand product (Mobic), in order to verify whether the generic product conforms to the regulatory standards of bioequivalence in the postmarketing setting. As a secondary exploratory aim, the pharmacodynamic effects of the two formulations were also evaluated by means of rating scales following hyperalgesia induced by cutaneous freeze injury. SUBJECTS AND METHODS A single 15 mg dose of generic or branded meloxicam tablets was administered to 24 healthy male volunteers in a crossover fashion. Plasma samples, collected for 24 hours after dosing, were assayed for meloxicam concentration by a validated highperformance liquid chromatography method. RESULTS THE ANALYSIS OF PHARMACOKINETIC PARAMETERS DID NOT SHOW ANY SIGNIFICANT DIFFERENCE BETWEEN THE TWO MELOXICAM FORMULATIONS: the 90% confidence intervals fell within the acceptance range of 80%-125% (0.84-1.16 for area under the curve [0-24], and 0.89-1.23 for peak concentration). No difference in the pharmacodynamic end point was observed between the two groups. CONCLUSION The pharmacokinetic profiles of the two meloxicam formulations confirm the regulatory criteria for bioequivalence; pharmacodynamic data indicate a similar antihyperalgesic effect. The two formulations can be used interchangeably in the clinical setting.

Abstract
The aim of this study is to develop milk-based formulations for ionized and unionized lipophilic drugs. Solubility studies of the following non-steroidal anti-inflammatory drugs (NSAIDs): mefenamic acid, tolfenamic acid, ketoprofen, meloxicam, tenoxicam and nimesulide in phosphate- and glycine-NaOH buffers at nominal pH 8-12, were performed. The solubilities of cyclosporine and danazol in water-ethanol solutions were studied. NSAIDs-, cyclosporine-, danazol-, aspirin-milk oral liquid formulations were prepared by adding the appropriate volume of (i) NSAIDs-alkaline buffer solutions, (ii) water-ethanol solutions of cyclosporine and danazol and (iii) aspirin aqueous solution to 150-200ml of milk. All the non-steroidal anti-inflammatory drugs exhibited increased solubility in the alkaline buffers. The actual pH values (range 6.7-7.7) of the final NSAIDs-milk formulations were very close to milk pH. The higher ethanol content in ethanol-water mixtures increased the solubility of danazol and cyclosporine. A 15mg meloxicam-, a 100mg cyclosporine- and a 500mg aspirin-milk formulation was administered orally to healthy volunteers. All these formulations showed a satisfactory in vivo performance. The strong buffering capacity of milk that was observed and the high solubility of unionized drugs in ethanol allow the preparation of drug-milk formulations with enhanced pharmacokinetic properties.

Abstract
A simple and selective CE using surfactant with UV detection is described for the simultaneous determination of selective cyclooxygenase-2 inhibitors, celecoxib, meloxicam, and rofecoxib. The simultaneous analysis of celecoxib, meloxicam, and rofecoxib was performed in Tris buffer (10 mM; pH 11) with 60 mM sodium octane-sulfonate and 20% ACN as an anionic surfactant and organic modifier, respectively. Under this condition, good separation with high efficiency and the required short analysis time is achieved. The linear ranges of the method for the determination of celecoxib, meloxicam, and rofecoxib were over 5-100 microg/mL; the detection limits at 200 nm (S/N = 3; injection 3.45 kPa, 5 s) were 2, 1, and 1 microg/mL, respectively. The small amount of sample required and the expeditiousness of the procedure allow content uniformity to be determined in individual pharmaceutical products.

Abstract
OBJECTIVE To compare the efficacy of meloxicam administered perioperatively with transdermal administration of fentanyl via a patch placed preoperatively in dogs undergoing orthopedic surgery. DESIGN Prospective study. ANIMALS 16 dogs. PROCEDURE Unilateral or bilateral osteotomy of the tibia and fibula was surgically performed, and a uniplanar external distraction device was placed in each limb. Postoperative pain and lameness were assessed 24, 48, and 72 hours after administration of the first of 3 doses of meloxicam (0.2 mg/kg [0.09 mg/lb], IV, given preoperatively, followed by 0.1 mg/kg [0.045 mg/lb], IV, after 24 hours, and 0.1 mg/kg, PO, after 48 hours) or preoperative placement of a transdermal fentanyl patch (50 microg/h) left in place for 72 hours. RESULTS No significant differences in total pain scores were detected between groups. Mean +/- SD lameness scores assessed at 24 and 72 hours were lower in dogs in the meloxicam group than dogs in the fentanyl group. Lameness scores decreased with time in a similar manner in both treatment groups. CONCLUSIONS AND CLINICAL RELEVANCE Perioperative administration of meloxicam or preoperative placement of a transdermal fentanyl patch provided effective and similar postoperative analgesia in dogs undergoing orthopedic surgery. However, because of its anti-inflammatory effects, treatment with meloxicam reduced the degree of lameness and resulted in rapid functional recovery of the limb.
