Hence, a generic or universal HPLC method interfaced with a UV detector for BHT can be used on any drug as long as the acceptance criteria on accuracy, precision, robustness, and other necessary requirements have been met. Similar to appearance, drug release, assay, and impurities, preservative testing is also required if a certain degree of preservative has to be included in the drug product to ensure an adequate shelf life. 

Generic products tested by the FDA and determined to be therapeutic equivalents are listed by the FDA in their publication Approved Drug Products with Therapeutic Equivalence Evaluations. These products contain the same active ingredients as their brand-name counterparts and also meet bioequivalence standards. The FDA recommends substitution only among products listed as therapeutically equivalent.
