Hypothesis

This study aims to develop and validate a method for the simultaneous quantitation of Losartan potassium and Metolazone using HPLC.

Conclusion

The developed HPLC method is effective for the simultaneous quantitation of Losartan potassium and Metolazone in pharmaceutical formulations.

Supporting Evidence

  • The method showed good linearity for both drugs over specified concentration ranges.
  • Precision studies indicated RSD values were less than 2%, meeting ICH guidelines.
  • The method was validated for accuracy with recoveries between 99% and 101%.

Takeaway

Researchers created a new way to measure two heart medications together using a special machine called HPLC, which helps doctors know how much medicine is in a pill.

Methodology

The method involves HPLC separation of Losartan potassium and Metolazone using a specific column and mobile phase, followed by validation for precision, accuracy, and robustness.
