The effect of particle size of disintegrants on the disintegration of tablets
- 194 Downloads
The effect has been studied of particle size of disintegrants on the disintegration time of tablets, compressed without a lubricant and after mixing the ingredients with magnesium stearate, respectively. The results show for the tablets containing a slightly swelling disintegrant, like potato and rice starch, a decreasing negative effect of mixing with magnesium stearate on the disintegration time of the tablets with decreasing particle size of disintegrant. Only a slight effect of particle size and of mixing time with magnesium stearate on the disintegration of the tablets is found for the tablets containing a strongly swelling disintegrant, like sodium starch glycolate.
