Quantification of S-amlodipine [PK / PD]
Hi Helmut and all members who contributed.
No problem my friend!
There is still time!!!
Thank you so much! Now I understood that calibrators prepared and quality control samples concentration will not be accurate. Because weighing of standard is a racemate! So, concentration of unknown samples will be inaccurate.
S-Amlodipine, let's go!
❝ I incorrectly assumed that you have a chiral method. Sorry.
No problem my friend!
❝ Validate the method with the racemate but state in the protocol that you will correct all concentrations once you have the l-enantiomer. Analyze the study samples with the racemate standards / QCs. This is a last resort - better than to wait for the enantiomer standard and risk that the samples degrade in the meantime. Avoid it in the future.
