Abstract:
OBJECTIVE: To improve the dissolubility and dissolution rate of carvedilol.METHODS: Carvedilol solid dispersions were prepared using solvent- melting and coevaporation methods with PEG- 6000 and PVP as carriers and in vitro dissolubility was studied in simulated gastric juice.RESULTS: The results of in vitro dissolubility test showed that the higher the carrier- car ratio,the faster the drug dissolution.The in vitro dissolubility of solid dispersions with PVP as carrier was faster than that of solid dispersions with PEG- 6000 as carrier.CONCLUSION: Accelerating the rate of in vitro release and improving bioavailability,carvedilol solid dispersion was a promising preparation.
