Piroxicam has two different crystalline forms (known as needle and cubic forms), that they are different in physicochemical properties such as biological solubility. In the current research, using Taguchi experimental design approach the influences of five operating variables on formation of the piroxicam polymorph shapes in recrystallization were studied. The variables include type of solvent,...

Abstract Saliva is widely used for clinical and laboratory analysis. This study proposed to use DNA extracted from saliva genotyping pharmacokinetics of piroxicam. A fast efficient method was determine relevant allelic variants CYP2C9 (*2 *3), since genetic factors can influence in non-steroidal anti-inflammatory drugs (NSAIDs) metabolization. Extract All Reagents Kit® extraction performed usin...

Many commonly used non-steroidal anti-inflammatory drugs (NSAIDs) also cause gastrointestinal toxicity, including the development of life-threatening peptic ulcers. We report that mast cell-deficient mice have an extremely high incidence of severe peptic ulceration when exposed to the NSAID piroxicam. This enhanced ulcer susceptibility can be reversed by reconstitution with mast cells. Furtherm...

The utilization and prescribing quality of non-steroidal anti-inflammatory drugs (NSAIDs) in Zagreb were assessed by calculating the number of defined daily doses (DDDs) from the number and size of packages of each prescription NSAID dispensed at 31 and 32 pharmacies during the years 2001 and 2002. NSAIDs accounting for 95% of overall NSAID utilization (DU95% segment) were analyzed. The proport...

No presente estudo foram preparadas micropartículas de poli(hidroxibutirato) contendo piroxicam pela técnica de emulsão-evaporação do solvente. A influência de alguns parâmetros do processo sobre a eficiência de encapsulação do fármaco foi avaliada por meio de um planejamento fatorial do tipo 2. A eficiência de encapsulação do piroxicam variou de 5,5 a 89,8%. Micropartículas ocas e irregulares,...

Piroxicam is a nonsteroidal antiinflammatory drug (NSAID) of the oxicam group and has anti-inflammatory, analgesic, antipyretic, and antiplatelet properties. It is a potent prostaglandin inhibitor with a long half-life in plasma (36-58 hours), meaning that it can be administered in a single daily dose. Multiple adverse systemic effects have been reported for piroxicam, of which the most common ...

piroxicam, an anti-inflammatory drug, exhibits poor water solubility and flow properties, poor dissolution and poor wetting. consequently, the aim of this study was to improve the dissolution of piroxicam. microparticles containing piroxicam were produced by spray drying, using isopropyl alcohol and water in the ratio of 40:60 v/v as solvent system, and spray chilling technology by melting the ...

We investigated the effects of piroxicam, a cyclooxygenase inhibitor, and esculetin, a lipoxygenase inhibitor, on 7,12-dimethylbenz[a]anthracene (DMBA)-induced mammary carcinogenesis in female rats. Seven days after receiving a 5-mg dose of DMBA, rats were fed either a high-fat (20% soybean oil) or low-fat (0.5% soybean oil) diet. One third of the rats received diets containing 0.01% piroxicam ...

Adverse skin reactions to drugs are frequent, with rates of reaction to many commonly used drugs exceeding 1%. We describe a 29-year-old woman admitted with a history of itching, rash, vesicles on her hands and soles, and edema on her tongue and oropharynx after trimethoprim-sulfamethoxazole, ciprofloxacin, methenamine anhydromethylene citrate, piroxicam, azithromycin, and ceftriaxone intake. E...
