Table II.
Parameters of Injectability, Plunger-stopper Break Loose Force (PBF), Maximum Force (F max), and Dynamic Glide force (DGF), for Formulation 1 Injected by a Given Needle-syringe Systems, as Determined from the Force-displacement Plot. The Results are Expressed as the mean of Three Determinations ± Standard Deviation
