Objective: To study the formulation technique of lacidipine tablet. Method: The optimal formulation were screened by using lactose as filler, starch as disintegrating agent, polyvinylpyrrolidone K30 as binder, magnesium stearate as lubricating agent to design test, and testing with granulation, fluidity of granule, appearance of tablet, disintegrating time, hardness, friability and dissolution rate as indexes. Results: Formula 1 and 2 had low dissolution speed and low dissolution rate. Formula 3 has uniform dissolution rate. Conclusion: The appearance, weight, content, and dissolution rate of manufactured lacidipine tablet satisfied the quality requirement.
