Answer / pooja
Potency is a measure of drug activity expressed in terms of
the amount required to produce an effect of given intensity.
Purity is a measure of the amount of API present in a sample
compared to those of related substances, impurities,
residual solvents, etc.

Answer / ravindra
Purity means other than impurity or absence of impurity &
we are calculating by area normalisation.
while Potency is content of that substances in the sample
and calculating it on dried basis ie. LOD, water content ,
residual solvent.

Answer / dixit kachhia
Potency = purity-(LOD/Water content+residual solvents+total
impurities+ ROI)
PURITY IS CARRIED OUT BY HPLC CHROMATOGRAAPHIC PURITY AND IS
%AREA OF MAIN PEAK where all peak integrated including all
known and unknown peaks due to product
i am not in favored of potency calculated on basis of assay
rather than purity because assay calculated against another
std and there will be a possibility of no. of errors in
define correct assay.
