Morphine is a drug which relieves pain and induces sleep. It is based on “Morpheus” the Greek god of dreams. It is obtained from opium and it was discovered by Friedrich Serturner, a German pharmacist. This is often only prescribed when the pain could not be treated by less potent medication since morphine is addictive. It is frequently used to help manage the pain during labor and heart attacks. The side-effects include vomiting, constipation, drowsiness, hormone imbalance, and addiction. Some of its brand names include MS Contin, Roxanol, Kadian, Morphabond, and Oramorph SR. Its street names include M, Monkey, Miss Emma, and White Stuff.
