Hypothesis

Can a new HPLC method effectively quantify potential impurities in fluoxetine hydrochloride?

Conclusion

The developed HPLC method is simple, precise, and accurate for quantifying impurities in fluoxetine hydrochloride.

Supporting Evidence

  • The method was validated to fulfill ICH Q2(R2) requirements.
  • The calibration curve was linear over the concentration range from LOQ to 120%.
  • The accuracy of the method is within the acceptable limit of 80%–120%.
  • The method can be employed for the regular analysis of potential impurities in fluoxetine hydrochloride.

Takeaway

Researchers created a new way to check for bad stuff in a medicine called fluoxetine, making sure it's safe to use.

Methodology

A high-performance liquid chromatography (HPLC) method was developed and validated according to ICH guidelines.
