Counterfeit Medications

Introduction & definitions — the WHO SSFFC → "Substandard & Falsified (SF)" framework

• Concept — counterfeit (falsified) medicines are a category of compromised medical product that — with substandard and adulterated drugs — undermines drug safety even after marketing approval; in Goodman & Gilman's postmarketing-safety framework, "drug quality" is the node under which counterfeit, substandard and adulterated products sit.
• Evolving terminology — the historical WHO umbrella term was SSFFC (Substandard, Spurious, Falsely-labelled, Falsified & Counterfeit). At the 70th World Health Assembly (WHA70, May 2017) Member States replaced it with the simpler "Substandard & Falsified (SF)" and three working definitions [WHO].
• Why "counterfeit" was dropped — the word became entangled with intellectual-property / trademark law (a commercial concern); WHO prefers "falsified" to keep focus on patient harm, not brand protection [WHO].
• WHO category 1 — Substandard — ("out of specification") authorised products that fail their quality standards/specifications — genuine, registered products that are sub-/super-potent, contaminated or degraded from poor manufacturing or quality control (a GMP / quality-systems failure) [WHO].
• WHO category 2 — Unregistered / unlicensed — products not evaluated/approved by the national or regional regulatory authority for the market where they are sold — they bypass the regulatory gate (diversion, unapproved imports) [WHO].
• WHO category 3 — Falsified — the public-health successor to "counterfeit" — products that deliberately/fraudulently misrepresent identity, composition or source: false name/strength/expiry; wrong/absent API or toxic substitute (e.g. diethylene glycol); false manufacturer/origin [WHO].
• The key exam distinction — substandard = genuine but out-of-spec (a quality/GMP failure) vs falsified = fraudulent, a criminal act defined by intent to deceive. A falsified product is usually also substandard, but the response differs — recall/GMP action vs criminal prosecution [WHO].
