Inorganic fluoride inhibits adenylate cyclase activity required for antidiuretic hormone effect on the distal convoluted tubule of the kidney. Fluoride also stimulates intrarenal vasodilation , leading to increased medullary blood flow, which interferes with the counter current mechanism in the kidney required for concentration of urine.

Together with enflurane and halothane , it replaced the flammable Diethyl ether ethers used in the pioneer days of surgery . Its name comes from being a structural isomer of enflurane, hence they have the same empirical formula. It is a racemic mixture of R and S optical isomers. Its use in human medicine is now starting to decline, being replaced with sevoflurane , desflurane and the intravenous anaesthetic propofol .

File General anesthetics simplicity and variety of structures.png thumb right Structures of general anaesthetics widely used in medicine. A general anaesthetic or anesthetic is a drug that brings about a reversible loss of consciousness . These drugs are generally administered by an anaesthetist anaesthesiologist in order to induce or maintain general anaesthesia to facilitate surgery . General anaesthetics have been widely used in surgery since 1842 when Crawford Long for the first time administered diethyl ether to a patient and performed a painless operation. It has always been believed that general anaesthetics exert their effects analgesia, amnesia, immobility by modulating the activity of membrane proteins in the neuronal membrane. However, the exact location and mechanism of this action are still largely unknown although much research has been done in this area. There are a number of outdated and modern theories that attempt to explain anaesthetic action. The concept of specific interactions between receptors and drugs first introduced by Paul Ehrlich ref name Cameron2006 cite journal author Cameron JW title The molecular mechanisms of general anaesthesia dissecting the GABAA receptor journal Continuing Education in Anaesthesia, Critical Care & Pain volume 6 issue 2 pages 49 53 year 2006 month January pmc doi 10.1093 bjaceaccp mki068 url http ceaccp.oxfordjournals.org cgi content abstract mki068v1 ref states that drugs act only when they are bound to their targets receptors . However, this concept is not working well in case of general anaesthetics because Molecular structures of general anaesthetics widely used in medicine are very simple and diverse so that there is no obvious structure activity relationship ref name Cameron2006 see structures of general anaesthetics widely used in medicine 1 ethanol, 2 chloroform, 3 diethylether, 4 fluroxene, 5 halothane, 6 metheoxyflurane, 7 enflurane, 8 isoflurane, 9 desflurane, 10 sevoflurane Most general anaesthetics h ... more details
