The aim of our study was to evaluate the applicability of yam (Dioscorea sp.) starch and arrowroot (Maranta arundinacea) starch as suspending agents in suspension. Paracetamol was used as a model drug because of its low solubility. It was found that the optimal concentration as suspending agent in paracetamol suspension was in the range of 7-8% for yam starch and 5-6% for arrowroot starch. All formulations were stable within the period of study with pH of 5.4-6.9. These results were comparable to those obtained from the sodium carboxymethyl cellulose (sodium CMC) which is a common suspending agent. It could be concluded that yam starch and arrowroot starch showed suspending activity in paracetamol suspension and could be applied as commercial suspending agent.
