The first undisputed reference to opium is found in the writings of Theophrastus in the third century B.C. Arab physicians were well versed in the uses of opium. Arab traders introduced the drug to the Orient, where it was employed mainly for the control of dysenteries. During the Middle Ages, many of the uses of opium were appreciated. In 1680, Sydenham wrote: "Among the remedies which it has pleased Almighty God to give to man to relieve his sufferings, none is so universal and so efficacious as opium." Opium contains more than 20 distinct alkaloids. In 1806, Sertrner reported the isolation of a pure substance in opium that he named morphine, after Morpheus, the Greek god of dreams. By the middle of the nineteenth century, the use of pure alkaloids in place of crude opium preparations began to spread throughout the medical world. In addition to the remarkable beneficial effects of opioids, the toxic side effects and addictive potential of these drugs also have been known for centuries. These problems stimulated a search for potent synthetic opioid analgesics free of addictive potential and other side effects.
