Abstract:
Objective To prepare Domiphen osmotic tablets of zero release above 80% in vitro. Methods Coating prescription was optimized by uniform design and the drug release characteristic was tested in vitro. Results The lemma thickness was (shown as lemma weight) 10.75 mg and the content of the porosity-making agent was 12%. The three batchs of drug tablets release pattern were in accord with zero order kinetics during 12 h. Conclusion This method is easy to produce and reaches initial devise request.
