Abstrakt		The polymorphism of piroxicam has been discussed by many authors, but it is still uncertain in how many polymorphic and pseudopolymorphic modifications it can exist. The results of DSC and IR analyses confirm that simple crystalization from different solvents yields modifications designated as I and II monohydrate. Depending on the cooling rate of the piroxicam melt, amorphous or matastable polymorphic forms referred to as III and IV were obtained.
