Abstract: Objective To design and evaluate a multifunctional and multiple unit oral DDS, which depends on the preparations of pulsatile release mini-tablets. Methods Based on the combinations of pulsatile release tablets, zero-order DDS could be obtained. Velocity-time curve, instead of the cumulative percentage drug release profile, was plotted. The nonlinear least square model fit program was applied to process the velocity data of dissolution. The test curves coincided with the theoretical curves from simple summation of v-t equations of individual pulsatile release tablets. Results Zero-order DDS were designed with two kinds of combinations. The amount of the two pulsatile should be 1:1. The combination of pulsatile release tablet could achieved the formulation from which Acetaminophen and Pseudoephedrine could be released in the same proportion. Conclusion The combination of delayed-onset sustained-release Tablet was better fit in with zero-order equation and Acetaminophen and Pseudoephedrine could be released in the same proportion.
