To evaluate the toxicity of short-term high doses of meloxicam in American kestrels ( Falco sparverius ), 32 male captive-born, 1- to 4-year-old American kestrels were randomly assigned to 4 groups: 3 groups treated with meloxicam (n = 9 per group) and a control group (n = 5). Meloxicam was administered orally via feeding tube in the proventriculus at 2, 10, and 20 mg/kg every 12 hours for 7 days for the treatment groups, while the control group received saline solution. The birds were evaluated for the presence of clinical signs, abnormalities in the complete blood cell count and in the plasma biochemical panel for the 20-mg/kg group, and gross and histopathologic lesions...

BACKGROUND: This study evaluated the antinociceptive action of α-(phenylalanyl) acetophenone (PSAP) in mice. METHODS: Evaluated whether the serotonergic, adrenergic and dopaminergic systems are involved in PSAP antinociceptive activity. PSAP was administered intragastrically (ig) 30min prior to formalin or glutamate test and compared with a standard drug, meloxicam (10mg/kg, ig). RESULTS: The treatment with PSAP (10-50mg/kg) caused inhibition in the neurogenic phase and reduced the paw oedema caused by intraplantar (ipl) injection of formalin...

BACKGROUND: 2, 4-Thiazolidinedione (TZD), pyrazole and thiazole heterocyclic rings exhibit wide range of pharmacological activities. Medicinal chemists use these heterocyclic moieties as scaffolds in drug designing and discovery. The existing medicaments, celecoxib and meloxicam, used for treating inflammation and pain are having, pyrazole and thiazole, respectively as a key scaffolds. Pyrazoles coupled with 2, 4-thiazolidinediones may display enhanced anti inflammatory activity. With this hope the title work was carried...

REVIEW
Ian S Wedmore, Frank K Butler
At the start of the Afghanistan conflict, battlefield analgesia for US military casualties was achieved primarily through the use of intramuscular (IM) morphine. This is a suboptimal choice, since IM morphine is slow-acting, leading to delays in effective pain relief and the risk of overdose and death when dosing is repeated in order to hasten the onset of analgesia. Advances in battlefield analgesia, pioneered initially by Tactical Combat Casualty Care (TCCC), and the Army's 75th Ranger Regiment, have now been incorporated into the Triple-Option Analgesia approach...

A 7-year-old female golden retriever dog was presented with a 2-week history of coughing and inappetence. Examination, radiographs, and blood analysis showed classic evidence of blastomycosis, confirmed with the MVista EIA urine antigen test. A 2-month course of itraconazole and a course of mirtazapine, meloxicam, furosemide, and tetracycline resulted in a successful outcome.

The ethyl acetate extract (SsAcOEt) from Serjania schiedeana, select fractions (F-6, F-12, F-13, F-14), and one isolated compound, were evaluated in 12-O-tetradecanoylphorbol 13-acetate (TPA) ear edema and kaolin/carrageenan (KC)-induced monoarthritis assays. SsEtOAc induced edema inhibition of 90% (2.0 mg/ear), fractions showed activity within a range of 67-89%. Due to the fact F-14 showed the highest effect, it was separated, yielding a proanthocyanidin-type called epicatechin-(4β → 8)-epicatechin-(4β → 8, 2β → O → 7) epicatechin (ETP)...

Human organic anion transporters (OATPs) are vital for the uptake and efflux of drugs and endogenous compounds. Current identification of inhibitors of these transporters is based on experimental screening. Virtual screening remains a challenge due to a lack of experimental three-dimensional protein structures. Here, we describe a workflow to identify inhibitors of the OATP2B1 transporter in the DrugBank library of over 5,000 drugs and druglike molecules. OATP member 2B1 transporter is highly expressed in the intestine, where it participates in oral absorption of drugs...

Meloxicam (MEL) shows a slow onset of action in severe pain patients due to delayed gastric motility. This study aimed to develop an amorphous solid dispersion (ASD) of MEL to achieve rapid oral absorption in severe pain patients. ASD formulations of MEL with hydroxypropylmethylcellulose (ASD-MEL/HPMC) and polyacrylates and polymethacrylates (ASD-MEL/EUD) were prepared and physicochemically characterized. Oral absorption behavior of MEL samples was also clarified in both normal and propantheline (PPT)-pretreated rats with impaired gastric motility...

Caustic paste disbudding is becoming more commonplace in North America. A large body of work has examined pain control for cautery disbudding and surgical dehorning, but fewer studies have evaluated pain control for caustic paste disbudding, and results conflict regarding benefits of local anesthesia. In humans, the pain associated with a caustic, chemical burn can differ in nature, duration, and intensity compared with a thermal burn. The objective of this clinical trial was to evaluate the effects of either a lidocaine cornual nerve block or a topical anesthetic incorporated into caustic paste on the acute pain of caustic paste disbudding...

The effects of the non-steroidal anti-inflammatory drugs (NSAIDs) on bone quantity and quality were investigated for years. However, there is lack of information on the impact of NSAIDs on the quality of tooth-supporting alveolar bone in absence of periodontal inflammation. Thus, the aim of this study was to evaluate histometrically the influence of a selective COX-2 NSAID (Meloxicam) on the inter-radicular bone mineral density in rats. Forty-nine adult male Wistar rats were randomly divided into four experimental groups: Subcutaneous injection of 0...

To enhance the therapeutic effects of meloxicam (MLX), we developed an oral MLX-loaded poly(ethylene glycol)-b-poly(ε-caprolactone) nanoparticles@hydrogel (MLX-NPs@hydrogel) preparation. The MLX-NPs were fabricated via a solvent evaporation method, and their morphologies were observed by a JEM-1011 transmission electron microscope (TEM). The poly(mPEGMA-co-MAA) hydrogels were synthesized, and studies on their pH sensibilities were carried out in pH1.2, 6.8, and 7.4 buffers. The final MLX-NPs@hydrogel preparation was obtained by immersing the hydrogels in the MLX-NPs suspensions (pH7...

BACKGROUND: Chemoprevention is a strategy which uses therapeutic agents which are essentially not anti-cancer drugs but, however, impedes the carcinogenesis. Meloxicam (MLX) is one such agent which has the potential to be employed in the chemopreventive therapy of colorectal cancer. However, MLX poses shortcomings with respect to its dose required for cytotoxicity. To improve the formulation, we used Quality by design (QbD) for optimization. QbD is a method that employs quality-improving scientific methods that build quality into the formulation by isolating the factors which affect the critical quality attributes the formulation...

Facial expressions are increasingly being used to assess pain in non-human species, including rodents, horses, and lambs. The development of these species-specific grimace scales has allowed for more rapid pain detection, which can lead to better animal welfare if intervention promptly occurs. For grimace scales to ever be used as a stand-alone measure of pain, it is important they correlate with established pain assessment tools, such as behavioral analysis. This preliminary study aimed to determine whether piglets exhibit pain grimacing and if these facial expressions correlate with their behavior...
