Gliclazide is a second-generation hypoglycaemic sulfonylurea that is useful in the treatment of Type 2 diabetes mellitus. It shows low aqueous solubility and dissolution rate and often shows low and irregular bioavailability after oral administration. This paper describes an approach to improve the Solubility of gliclazide by using solid dispersions (SDs) in polyethylene glycol 4000 (PEG 4000)....

phenomena from solid dispersions with enteric coating agents in JP XI 2nd fluid(pH 6.8). Nifedipine,griseofulvin and spironolactone were used as drugs.The rate of crystallization of all drugs was remarkably inhibited by the presence of CMEC.It was found that the inhibition was not due to solubilization of the drugs by CMEC. The crystallization kinetics from supersaturated solutions suggested th...
