Evaluation of Yam (Dioscorea sp.) Starch and Arrowroot (Maranta arundinacea) Starch as Suspending Agent in Suspension

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.
