Abstract

 A study was made on the disintegration time and in vivo absorption rate of sulphadimidine tablets prepared by direct compression technique using Celutab (50% w/w) as an excipient. Tablets of greatly different disintegration times were selected for this investigation. Using urinary excretion method, it was shown that there is a relationship between disintegration time and in vivo absorption of sulphadimidine tablets, in that the tablet with faster disintegration time gives a higher absorption as indicated by the excretion rate calculated from the cummulative amount of sulphadimidine excreted.
