FORANE (isoflurane, USP) may be used for induction and maintenance of general anesthesia.

 Data Sheet
ISOFLURANE is a halogenated volatile anaesthetic which induces and maintains general anaesthesia by depression of the central nervous system and resultant loss of consciousness.
The pharmacokinetics of ISOFLURANE are those of inhaled gaseous or volatile anaesthetics for which blood concentrations are related to alveolar concentrations through the established partition coefficients, and the distribution to tissues is also determined by solubility coefficients which are relatively constant under a wide variety of circumstances.
ISOFLURANE shows very low solubility in blood and body tissues, much lower than for enflurane and halothane, thus its partial pressure (concentration) in alveolar gas or arterial blood rises to 50% of the inspired partial pressure (concentration) within 4-8 minutes of the start of its inhalation, and to 60% within 15 minutes.

The effect of isoflurane on trifluoroethene (TFE) defluorination and cytochrome P450 inactivation was examined in rats to determine the influence of this anesthetic on in vivo fluoroethene metabolism.
Exposure of rats to TFE (0.5%, v/v) or a mixture of TFE and isoflurane (0.5% each) in oxygen for 60 min resulted in plasma fluoride increased over that in nonexposed or isoflurane (0.5%)-exposed animals.
These data demonstrate that the defluorination of TFE in vivo by the phenobarbital-inducible cytochrome P450 isozymes is increased by isoflurane, and that isoflurane enhances the ability of TFE to inactivate cytochromes P450 in an isozyme-selective manner.
