Management of severe pain requiring continuous, around-the-clock analgesia over extended periods when alternative treatments are insufficient. Commonly used for cancer pain, severe chronic back pain, or pain following major surgery.
Ms Contin contains morphine sulfate, an opioid agonist that binds to mu-opioid receptors in the central nervous system. This binding alters the perception of pain and emotional response to pain, providing analgesic effects. The controlled-release formulation allows for gradual medication release over 12 hours.
Ms Contin carries a boxed warning for addiction, abuse, and misuse risk, as well as potentially fatal respiratory depression. It should not be discontinued abruptly without medical supervision. Combining with benzodiazepines, alcohol, or other CNS depressants increases serious risks. Requires careful dose titration by healthcare providers. Due to its high potential for dependence, it is typically reserved for pain severe enough to require continuous opioid treatment.
