Answer Posted / dhanalakshmi
Purity: is the percentage of a drug without its degradation
products or impurities or isomeric forms. The isomeric forms
may be pharamlogically active, but in case of determination,
isomeric forms will not be considered.
Potency: is the measurement of a drug how potent it is. In
this case the amount of drug may consider the
pharmacologically active forms and impurities.
