ABSTRACT
Two simple and sensitive spectrophotometric methods have been developed for the estimation of Nebivolol hydrochloride in pure and pharmaceutical dosage forms. Method 1 is based on Ion-association complex formation of the drug with (SBT λmax 515 nm). Method 2 is based on Ion-association complex formation of the drug reacts with (BTB λmax 410nm). These methods have been statistically evaluated and found to be precise and accurate.
ABSTRACT
Two simple and sensitive spectrophotometric methods have been developed for the estimation of fenofibrate in pure and pharmaceutical dosage forms. Method A and B are based on ion association complex formation of the drug with Methylene Blue and Saffranine respectively. Beers law is obeyed in the concentration range of 5-15 μg/ml (Method A) and 10-30μg/ml (Method B) with good correlation coefficients. These methods have been statistically evaluated and found to be precise and accurate.
