Opioids are commonly prescribed because of their effective
analgesic or pain relieving properties. Many studies have shown that properly
managed medical use of opioid analgesic drugs is safe and rarely causes
clinical addiction, which is defined as compulsive, often uncontrollable use.
Taken exactly as prescribed, opioids can be used to manage pain
effectively.
Among the drugs that fall within this class - sometimes referred to
as narcotics - are morphine, codeine, and related drugs. Morphine is often used
before or after surgery to alleviate severe pain. Codeine is used for milder
pain. Other examples of opioids that can be prescribed to alleviate pain
include oxycodone (OxyContin-an oral, controlled release form of the drug);
propoxyphene (Darvon); hydrocodone (Vicodin); hydromorphone (Dilaudid); and
meperidine (Demerol), which is used less often because of its side effects. In
addition to their effective pain relieving properties, some of these drugs can
be used to relieve severe diarrhea (Lomotil, for example, which is
diphenoxylate) or severe coughs (codeine).
Opioids act by attaching to specific proteins called opioid
receptors, which are found in the brain, spinal cord, and gastrointestinal
tract. When these drugs attach to certain opioid receptors in the brain and
spinal cord they can effectively block the transmission of pain messages to the
brain.
In
addition to relieving pain, opioid drugs can affect regions of the brain that
mediate what we perceive as pleasure, resulting in the initial euphoria that
many opioids produce. They can also produce drowsiness, cause constipation,
and, depending upon the amount of drug taken, depress breathing. Taking a large
single dose could cause severe respiratory depression or be
fatal.
Opioids may interact with other drugs and are only safe to use
with other drugs under a physician's supervision. Typically, they should not be
used with substances such as alcohol, antihistamines, barbiturates, or
benzodiazepines. These drugs slow down breathing, and their combined effects
could risk life-threatening respiratory depression.
Chronic use of opioids can result in tolerance to the drugs so that
higher doses must be taken to obtain the same initial effects. Long-term use
also can lead to physical dependence - the body adapts to the presence of the
drug and withdrawal symptoms occur if use is reduced abruptly.
Symptoms of withdrawal can include restlessness, muscle and bone
pain, insomnia, diarrhea, vomiting, cold flashes with goose bumps ("cold
turkey"), and involuntary leg movements.
Options for effectively treating addiction to prescription opioids
are drawn from experience and research on treating heroin addiction. Some
examples follow.
Methadone, a synthetic opioid that blocks the effects of
heroin and other opioids, eliminates withdrawal symptoms, and relieves drug
craving. It has been used for over 30 years to successfully treat people
addicted to opioids.
Other medications include LAAM (levo-alpha-acetyl-methadol), an
alternative to methadone that blocks the effects of opioids for up to 72 hours.
Naltrexone is a long acting opioid blocker often used with highly motivated
individuals in treatment programs promoting complete abstinence, and also to
prevent relapse.
Buprenorphine, another synthetic opioid, will soon be
available. Also, naloxone counteracts the effects of opioids and is used
to treat overdoses.
