Abstract :
The arithmetic mean roughness, Ra, values were determined by scanning electron
microscopic technique of different core models (furazolidone, nitrofurantoin and acetyl salicylic
acid), coated by HPMC film forming solution containing 10 wt% of various molecular weight
PEGs. The results showed that both plasticizer molecular weight and core surface free energy
could have a significant influence on Ra
