Is rifampin and rifampicin the same

Yes, rifampin and rifampicin are the same drug - just different names used in different regions.
  • Rifampicin is the International Nonproprietary Name (INN) used in most of the world, including the UK, Europe, India, and Australia.
  • Rifampin is the name used in the United States and Canada (the USAN - United States Adopted Name).
Both refer to the same antibiotic: a rifamycin-class bactericidal drug that inhibits bacterial RNA polymerase. It is a first-line drug for tuberculosis, leprosy, and is used to eliminate meningococcal carriage, among other indications.
The chemical compound, mechanism of action, dosing, and clinical use are identical regardless of which name is used.
