Coating prescription was optimized by uniform design and the cumulative rates of drug release of different formulated preparations were measured,pharmaceutical features of domiphen bromide osmotic tablet and mechanism of drug release were studied.RESULTS:
The dosage of PEG-400 and the coating membrane thickness all had an effect on drug release.The optimal coating technique was analyzed as 12%of PEG-400 and 10mg of coating.Spray speed,temperature and rotation speed did not affect releasing profiles.CONCLUSION:
Improvement in formulation of coat of domiphen bromide osmotic tablet can result in drug release for 12h,whose mechanism includes diffusion and osmotic pump principle.
