The authors inadvertently switched the words “qualitative” and “quantitative” in paragraph two under the header “Formulation Design of Generic Topical Drug Products.” The correct sentence reads as follows:

If feasible, the major formulation goal for a generic topical drug product is qualitative sameness (Q1, same components as the RLD) and quantitative sameness (Q2, same components in same concentration as the RLD, i.e., within ±5%) to the RLD [5, 6].
