Definition

A fluorinated isopropyl ether with general anesthetic activity. Although the mechanism of action has not been fully elucidated, sevoflurane may interfere with the release and re-uptake of neurotransmitters at post-synaptic terminals, and/or alter ionic conductance following receptor activation by a neurotransmitter. This agent may also interact directly with the lipid matrix of neuronal membranes, thereby affecting gating properties of ion channels. In addition, sevoflurane may activate gamma-aminobutyric acid (GABA) receptors, hyperpolarizing cell membranes and resulting in a general anesthetic effect, a decrease in myocardial contractility and mean arterial pressure, and an increased respiratory rate.
