Ultane (sevoflurane) Volatile Liquid For Inhalation is an anesthetic drug used to induce and maintain general anesthesia in adult and pediatric patients during surgery. Ultane is available in generic form. Like other halogenated inhalational anesthetics, sevoflurane's precise mechanism to induce and maintain general anesthesia is unknown. There have been multiple attempts to identify a unitary hypothesis. However, no single proposed mechanism of action has fully explained their clinical effects. A current working hypothesis is that inhaled anesthetics enhance inhibitory postsynaptic channel activity (gamma-aminobutyric acid (GABA) and glycine) and inhibit excitatory synaptic channel activity (N-methyl-D-aspartate (NMDA), nicotinic acetylcholine, serotonin, and glutamate) in the central nervous system.<br /><br /> By: MSc Hoda Sabah Jabr
