A process for the preparation of a stable dispersion of solid particles, in an aqueous medium comprising combining (a) a first solution comprising a substantially water-insoluble substance which is a thiazole compound of Formula I, a water-miscible organic solvent and an inhibitor with (b) an aqueous phase comprising water and optionally a stabiliser, thereby precipitating solid particles comprising the inhibitor and the substantially water-insoluble substance; and optionally removing the water-miscible organic solvent; wherein the inhibitor is a non-polymeric hydrophobic organic compound as defined in the description. Also claimed are stable dispersions obtainable by the process, solid particles obtainable by the process and use of such particles. The process provides a dispersion of solid particles in an aqueous medium, which particles exhibit reduced or substantially no particle growth mediated by Ostwald ripening. The process is particlularly suitable for the preparation of small (sub-micron) aqueous dispersions of a substantially water-insoluble pharmacologically active substance.
The present invention relates to compounds of formula (I):
in which R
1
and R
2
independently represent phenyl, thienyl or pyridyl and R
3
represents a group —X—Y—NR
4
R
5
in which X is CO or SO
2
; Y is absent or represents NH and the other substituente are as defined in the description and their use in the treatment of obesity, psychiatric and neurological disorders and to pharmaceutical compositions containing them.
