Abstract

The coprecitation of phenobarbital-PVP was prepared by solvent method. The ratios of phenobarbital and PVP are 1:3 and 1:10. The statistical analysis of dissolution rates showed extremely significant difference (P<0.01) between pure drug and mechanical impurity, coprecitation; significant difference (0.01<P<0.05)between mechanical impurity and coprecitate and no difference between coprecindion of different rations (P>0.05)
