The present invention relates to a process for the preparation of
inclusion compounds of piroxicam with .beta.-cyclodextrin. More
particularly, according to the process of the invention, the aqueous
solution of two components is subjected, before drying, to a freezing
process at very high rate. The resulting products have physico-chemical
characteristics as well as technological and biopharmaceutical properties
which are advantageous compared with those obtained according to the
prior art processes. The resulting products are suitable for preparing
pharmaceutical compositions for the oral administration.
