Metformin and linaglibtin film coated tablet [Bioanalytics]
I have done bioanalysis of so many studies of metformin and linagliptin. I have not observed such issues.
There is no problem with stability of linagliptin in samples.
Our LLOQ is 0.1 ng/mL for 2.5 mg dose.
Time point selection is also playing role in getting adequate results.

To call the statistician after the experiment is done
may be no more than asking him to perform a postmortem examination:
he may be able to say what the experiment died of.
