• "Morphine is an alkaloid present in opium, and is probably the most effective drug for the relief of extreme pain...Because of the adverse habit-forming characteristic of morphine, certain synthetic substitutes have been sought." 1
• "Morphine ans its relatives, widely used as painkillers in developed countries, can be fairly expensive and are often taken for extended periods of time." 2
• "Analgesic...Morphine relieves pain, but it also constipates and suppresses the urge to cough...Morphine was widely used during the American Civil War both for relieving pain of battle wounds and for controlling diarrhea...The more potent opioid analgesics - morphine, codeine, and heroin - moderate the brain's perception of pain by binding to receptor sites on neurons in the central nervous system." 3
• "Analgesic (narcotic), preanesthetic, antitussive, antiperistaltic." 4
