Why do some people react badly to generic medications? Even though generics are approved as equivalent, differences in inactive ingredients and absorption can cause real side effects-especially for drugs with narrow therapeutic indexes like levothyroxine and warfarin.
Cmax and AUC are the two key metrics used to prove that generic drugs work the same as brand-name versions. Cmax measures peak concentration, while AUC measures total exposure. Both must fall within 80%-125% of the original drug to ensure safety and effectiveness.
