Piroxicam-β-Cyclodextrin: A GI Safer Piroxicam
Although NSAIDs are very effective drugs, their use is associated with a broad spectrum of adverse reactions in the liver, kidney, cardiovascular (CV) system, skin and gut. Gastrointestinal (GI) side effects are the most common and constitute a wide clinical spectrum ranging from dyspepsia, heartburn and abdominal discomfort to more serious events such as peptic ulcer with life-threatening comp...
متن کاملNew Crystalline Forms of Piroxicam
Four new crystalline forms of piroxicam have been obtained and studied by single-crystal X-ray structure analysis. These comprise an addition salt with hydrochloric acid, acetic and isobutyric acids solvates, as well as piroxicam and furosemide cocrystal acetone solvate. All these new structures contribute to the variety of already known piroxicam crystalline forms. The analysis of conformation...
متن کاملStimulation of apoptosis by sulindac and piroxicam.
1.Sulindac, cis-5-fluoro-2-methyl-1-(p-methylsulphinylbenzylidene)indene-3-ace tic acid, inhibits growth of colon polyps and cancers. This effect has been attributed to inhibition of prostaglandin synthesis but more recent observations indicate that, in vitro, cells that do not have cyclo-oxygenase nor RNA for synthesis of such enzymes are affected by sulindac. Therefore the presumptive effect ...
متن کاملThe effect of rifampicin on piroxicam kinetics.
Rifampicin is known to influence the metabolic disposition of other drugs because of its 'enzyme inducing' effects in the liver (1, 6). The microsomal enzymes catalyze glucuronide conjugations and most of the oxidation of the drugs. Reduction and hydrolysis of drugs are catalyzed by both microsomal and non-microsomal enzymes (3). Hydroxylation and glucuronide formation are involved in the metab...
متن کاملCrystal modifications and dissolution rate of piroxicam.
Piroxicam is a nonsteroidal anti-inflammatory drug with low aqueous solubility which exhibits polymorphism. The present study was carried out to develop polymorphs of piroxicam with enhanced solubility and dissolution rate by the crystal modification technique using different solvent mixtures prepared with PEG 4000 and PVP K30. Physicochemical characteristics of the modified crystal forms of pi...
