The detection limit was
found to be 0.26 lg mL1 (Saha et al., 2002). Ultraviolet spectrophotometric
method for the determination of celecoxib in
bulk and its pharmaceutical formulation (dispersible tablets
and capsules) has been developed. The absorbance maxima of
celecoxib in a mixture of methanol and 0.01 N sodium hydroxide
(1:1 v/v) were determined at 253.1 nm. Beer’s law is obeyed
over concentration range of 8–22 lg mL1 with correlation
coefficient r > 0.999 (Sahu et al., 2009).
