Encapsulation of Nicardipine Hydrochloride and Release from Biodegradable Poly(D,L-lactic-co-glycolic acid) Microparticles by Double Emulsion Process: Effect of Emulsion Stability and Different Parameters on Drug Entrapment

Figure 12

Effects of homogenizer speed for the 1st emulsion on the particle size (blue solid circle) and the entrapment efficiency (orange vacant circle) of the PLGA MPs (a is significantly different at the level when comparing among the homogenizer speeds in each group).
