Accuracy/recovery studies
The recovery studies were carried out at 80%, 100% and
120% of the test concentration as per ICH guidelines. The
percentage recovery of ATL and ATV at all the three levels
was found to be satisfactory (Table 2). For ATL, the %
recovery was found between 98.15% and 99.66% and for
ATV between 99.96% and 101.04%, respectively.
