WebJun 12, 2009 · The dissolution data show that the dissolution of piroxicam pure drug is higher at pH 1.2 compared to that at pH 4.0. Piroxicam (Fig. 1) is an amphoteric compound, with a weakly acidic 7-OH proton (pK a = 5.07) and a weakly basic pyridyl nitrogen (pK a = 2.33) . Accordingly, the pyridyl nitrogen is protonated (about 92%) at pH 1.2, whereas the ... WebMay 1, 1996 · Meloxicam was soluble at neutral pH but became rapidly insoluble with decreasing pH. At very low pH its solubility increased, indicating a second p Ka value and the existen of a cation species. The very low solubility of meloxicam in acidic environments suggests it may cause few local gastrointestinal adverse events.
