14 drugs in the Blood family lose patent protection between 2026 and 2031. The family comes from the WHO ATC classification of each drug's ingredient; it is a filter, not a claim about any drug's approved indication.
This is the earliest date a generic could enter; it is not a guarantee one will. We calculate it as the later of the last patent the company listed with the FDA and the last regulatory exclusivity. Companies often reach settlement agreements with generic makers for a different date, and those agreements are not public in this data.
