DPC Dissolution Profiles Comparison

DPC Dissolution Profiles Comparison is a software designed for evaluation of the similarity between dissolution profiles.

The application allows:

  • selection of an appropriate profile comparison method for a given case,
  • standardization of the performed statistical analyzes and interpretation of the results,
  • automatic report generation in tabular and/or graphical form for submission of registration documentation.

All you need is to enter the data and press a button to get a full report in the form of a Microsoft Word or PDF document. The report includes results of the statistical analyses and comments to facilitate the interpretation of the obtained results.
Optionally, the data can be stored in a dedicated database.

The methods used in the module comply to the recommendations of the EU EMA and the US FDA.

The software has been validated according to cGxP requirements.
