The discovery of morphine, which occurred in 1803, transformed the medical treatment of pain and chronic diseases (Levinthal, 2005). Morphine, a narcotic or opioid, is widely used in the medical field today and is specifically used therapeutically to treat moderate to severe pain in individuals. The most common routes of administration for morphine are oral and intravenous administration (Angel, Gould, Carey, 1998). Morphine acts by binding to opioid receptors in the brain and thus reduces the perception of pain and emotional responses to pain (Weil and Winifred, 2004). The paper will focus on the therapeutic uses of morphine for individuals. Morphine is used in the treatment of pain with individuals suffering from cancer and acute myocardial infarction. Morphine is also administered to patients after surgery to decrease pain and is even thought to decrease the chances of developing posttraumatic stress disorder (Busse, 2006; Herlitz, Hjalmarson, and Waagstein, 1989; Levin, 2010).

Morphine Administration to Cancer Patients

According to World Health Organization, cancer pain can be controlled effectively with oral morphine in up to 90% of individuals with cancer (Ahmed, et al. 2010). Cancer patients benefit significantly from the effects of morphine on severe or chronic pain (Weil and Winifred 2004). A common treatment plan for cancer patients is to follow the “analgesic ladder” approach. The first step in this approach is to administer a non-opioid analgesic, such as aspirin, paracetamol, or a non-steroidal anti-inflammatory drug (Hanks, et al., 1996). Secondly, a week opioid is administered to the individual. Once the weak opioid is proven inadequate the third step is followed and a strong opioid is administered. ...

...tic efferent discharge. (Zelis, et al., 1974). The capacity of the peripheral vascular bed is increased and has reduced systemic venous return (Vasko, 1966). “Medical Phlebotomy” is a term that is commonly used to describe the effects of morphine of pulmonary edema (Vismara, Leaman, and Zelis, 1976).

Unfortunately, morphine can have side effects that may result in suppression of the central nervous system and ventilator failure. In addition, morphine may aggravate bradycaradia, hypotension, and in small cases respiratory depression. Naloxone is given to patients in order to aid in reversing these negative effects of morphine. With large doses of morphine, nausea and vomiting are potential side effects and may be treated with a phenothiazine. For theses reasons, morphine continues to be researched for the treatment of pulmonary edema (Cotter, et al., 2001).
