Hypothesis

The automated spectrophotofluorometric method is as effective as the gas chromatographic method for measuring content uniformity of conjugated oestrogens in pharmaceutical preparations.

Conclusion

The automated method is faster and equally effective for routine testing of content uniformity in oestrogen tablets.

Supporting Evidence

  • The automated method reduced testing time from 16 hours to 3 hours.
  • Both methods produced comparable results for content uniformity.
  • The coefficient of variation for the automated method was 2.57%, indicating consistency.

Takeaway

Scientists found a quicker way to check if oestrogen tablets have the right amount of medicine, which saves a lot of time.

Methodology

The study compared a gas chromatographic method with an automated spectrophotofluorometric method for measuring oestrogens in tablets.
