In vitro release of 5-FU was observed at 37°C in simulated gastric fluid (SGF, pH 1.2) and simulated intestinal fluid (SIF, pH 7.4). At specific time intervals, 3 ml of sample solution containing released drug was taken. The absorbance of released drug was determined by UV-vis spectrometer at 266 nm. Drug release experiments were observed in triplicate, average of drug release was calculated as in Eq 10.
