Objective: To study the formulation of Naoxuekang dispersible tablets.
Methods: The formulation was determined by pre-processing leech extractum prior to a series of experiments used to screen excipients like bulking agents and disintegrants and so on, and by adding disintegrants within and without.
Results: Microcrystalline cellulose was determined as the bulking agent, and carboxymethyl cellulose and low-substituted hydroxypropyl cellulose were determined as the disintegrants of Naoxuekang dispersible tablet formula.
