| Hazard Note | Flammable/Toxic |
| Toxicity | An isomer of enflurane with similar anesthetic properties. Isoflurane has less effect on myocardial function, leaving the cardiovascular system normally responsive to epinephrine or hypercarbia, and it does not cause a marked increase in seizure susceptibility. It was not widely used because of reports that it caused increases in liver neoplasms in mice, but this observation has been challenged and the compound reintroduced. |
