Use of the crushing strength parameter for quality control of phenobarbital-microcrystalline cellulose tablets.
Three variables of the tablet manufacturing process (duration of mixing with lubricant, maximum compression force and compression rate) were studied for their effects on various properties of direct compression phenobarbital-microcrystalline cellulose tablets. Mixing time and maximum compression force were found to have a marked influence on friability and dissolution rate; crushing strength was found to be a useful parameter for quality control.
