In this article “new cost-effective RP-HPLC method development and validation for quantitative estimation of ivacaftor in the
pharmaceutical formulation” developed. This study includes RP-HPLC Spectrophotometric method development, such as economical
and simple HPLC method was optimized during development and validated accordingly in tablets of ivacaftor. The developed method
may utilize for the analysis of ivacaftor at the laboratory level. The result shows that developed methods are cost-effective, rapid
(Short retention time), simple, accurate (the value and %RSD between 2-5), precise, and can be used for the intended purpose on the
tablet dosage form. The present proposed method is capable of better separation of analyte and qualifies on the point of analytical
validation such as linearity, specificity, accuracy, precision, robustness, LOD, and LOQ on a marketed formulation. The simplicity,
rapidity, and reproducibility of the developed method qualify the objective of the research. Results of analysis of the ivacaftor tablet
formulations are arranged in the experimental, result, and discussion section. The portion of ivacaftor found in terms of quantity was between 98-102% and also within USP 29 chapter (541) acceptance criteria.
