What Are Halogenated Hydrocarbons within ATC Class N01AB?
Definition and Usage
Halogenated hydrocarbons are organic compounds wherein hydrogen atoms are replaced with halogens (fluorine, chlorine, bromine, or iodine). These compounds serve primarily as:
- Inhalational anesthetics: e.g., halothane, isoflurane, enflurane, sevoflurane
- Antiseptics and disinfectants: e.g., chlorinated hydrocarbons used in sterilization

| Substance | Chemical Formula | Primary Use | Status |
|---|---|---|---|
| Halothane | C₂HBrClF₃ | General anesthetic | Declining, phased out in many markets |
| Isoflurane | C₃H₂ClF₅ | Inhalational anesthetic | Widely used, stable patent landscape |
| Sevoflurane | C₆H₧F₃O | Inhalational anesthetic | Market leader, diverse patent activity |
| Enflurane | C₃H₂ClF₅ | Anesthetic (less common) | Reduced use due to safety concerns |
