A validated RP-LC method for salmeterol and fluticasone in their binary mixtures and their stress degradation behavior under ICH-recommended stress conditions
(Maik Nauka Publishing / Springer SBM, 2014)
Simple, accurate, precise and fully validated analytical methods for the simultaneous determination of salmeterol xinafoate and fluticasone propionate in combined dosage forms have been developed. These drugs were exposed ...
Determination of pKa values of some antipsychotic drugs by HPLC-correlations with the kamlet and taft solvatochromic parameters and HPLC analysis in dosage forms
(2013)
In this study, ionization constant (pKa) values were determined by using the dependence of the retention factor on the pH of the mobile phase for four ionizable drugs, namely, risperidone (RI), clozapine (CL), olanzapine ...
