A lot number (also called batch number) links a product to its specific manufacturing batch, allowing traceability of the complete manufacturing history, including production date, site/line, quality control records, and distribution. This identifier is essential for recalls, investigations, and quality assurance.
Therapeutic equivalence ratings (A) come from Orange Book codes (e.g., AB), scheduling (B) is set under the CSA, and drug interactions (C) are clinical information-not tied to a product's lot.
