Acetaminophen, a poor soluble drug was used as a model drug to evaluate its release characteristics from different formulations. The USP paddle method was selected to perform the dissolution profiles carried out by USP apparatus 2 (paddle) at 50 rpm in 900 ml phosphate buffer pH 5.8. Successive dissolution time, time required for 25%, 50% and 80% of the drug release (T25%, T50%, T80%) was used to compare the dissolution results. A One way
