Learning Objectives
After completing this activity, you should be able to:
• Recognize opioid-induced constipation (OIC) as one
of the most common side effects of opioid therapy
• Identify and implement steps to remove barriers to
effectively communicating with patients about OIC
and treatment options
• Determine appropriate prophylactic and prevention
measures for individual patients
• Employ an evidence-based OIC treatment protocol
which maintains patient dignity, quality of life and
pain control
The Problem is Pain
Aging population = increased need for pain
relief
Appropriate use of opioid therapy for pain
management increased in recent years
90% of chronic pain patients receive
opioids

Constipation
Chronic Constipation:
Defecation < 3 times per week
• Primary: lifestyle issues
• Secondary: physiologic or metabolic cause
• Iatrogenic: pharmacologic agents or medical
interventions
OIC: Patient Perception is Key

What Happens in OIC?
Opioids bind to μ-opioid receptors
in GI tract
GI motility, secretion, fluid
absorption & blood flow affected
Colonic transit delayed
Sphincter tone increases
Defecation inhibited

Impact on Quality of Life
Risk of bowel obstruction, rupture,
death
Persistent constipation = poor ECOG
score
Patients would rather return to the pain
than continue with the constipation

What Do Patients Do?
They skip doses,
reduce dosages or stop
taking their medication
altogether because of
opioid-induced side effects
Bell TJ et al. Pain Med. 2009. 10:35-42
The Return of Pain
Patient suffers
pain
Patient reduces
opioid use due to
side effects
Opioid-induced
constipation
Patient takes
opioids for relief
Relief occurs
The Return of Pain
92%
experienced
increased pain
as a result
Bell TJ et al. Pain Med. 2009. 10:35-42
86%
said the pain

quality of life
86%
said the pain
affected their
activities of

The Patient Speaks
“The [constipation] is terrible. I tell you, at
first I guess they didn’t tell me about it. And
I must have taken [a mild opioid with
acetaminophen] for some ungodly reason. I
don’t know why. But I took it. And I took it
for 24 hours or something like that. Anyway,
I had such terrible constipation. I mean, it
was just absolutely horrendous. Nobody
told me anything…I tell you, I was pretty
upset. I gave up on the pain medicine.”
--Patient with lung cancer
Schumacher KL, Cancer Nurs. 2002; 25:125-133.
Prescribing Opioids
Preventing Constipation
Set Realistic Expectations
Get baseline bowel history
Identify other medications that may cause or
exacerbate constipation (antihypertensives, antidepressives)
Provide pain/bowel movement log
Discuss lifestyle interventions
Plan follow-up communication

Titrate Dosage
Does not prevent
constipation but. . .
• Provides opportunity
to identify when
constipation becomes
a problem
• Allows more
aggressive treatment
earlier
Explain to patient why
you started with lower
dose:
• Minimize side effects
(sedation, nausea,
confusion)
• Allow earlier
intervention when
side effects become a
problem

Communicate
•Do you feel more constipated than normal?
•When was your last bowel movement?
•Can you describe the consistency?
•Has there been a change in the frequency
or type of BM you have?
•How does it feel during a BM?
(pain? straining?)
•How do you feel after defecation?
(completely empty?)
•When did the change occur?
•What are you doing about it?

Evidence-Based Practice
Recommendation
OIC should be defined by both quantitative and
qualitative criteria, with the patient’s perception of
its impact on quality of life considered.
Patient/physician communication regarding the
likelihood of OIC, its prevention, treatment options
and treatment efficacy should be incorporated into
the overall treatment plan.

Evidence-based Practice
Recommendation
Patient education on lifestyle approaches that may
prevent OIC or reduce its severity should be
provided when opioids are prescribed.
Clinicians should also consider prophylactic laxatives
(bowel routine) based on individual patient needs.

Opioid Antagonists:
Naloxone, Nalmefene, Naltrexone
– Systemic yet with low bioavailability
– May reverse OIC but . . .
• Cross blood/brain barrier
• May lead to opioid withdrawal and pain

Opioid Antagonist:
Methylnaltrexone
• Derivative of naltrexone
• Decreases lipid solubility so does not cross
Blood-Brain Barrier
• No effect on CNS
• High μ-affinity; low κ-affinity; no δ affinity
Yuan CS, Israel RJ. Expert Opin Investig Drugs. 2006;15:541-552.
Methylnaltrexone
in OIC
• Indicated for treatment of OIC in patients with
advanced illness who are receiving palliative care,
when response to laxative therapy has not been
sufficient
• No trials of use beyond 4 months
• Significantly reduces transit time and time to bowel
movement compared with placebo
• Subcutaneous injection only
• Most common adverse effects: orthostatic
hypotension (dose-limiting), abdominal cramps,
flatulence, abdominal pain, nausea.
U.S. Food & Drug Administration Center for Drug Evaluation & Research Approval History NDA 021964
Opioid Antagonists:
Alvimopan
• Does not cross BBB
• Higher-binding affinity for μ-opioid receptors and
higher potency than methylnaltrexone
• Active metabolite that is absorbed systematically
• Little-to-no effect on CNS-mediated effects
• Adverse effects include: low blood calcium levels,
anemia and gastrointestinal problems, including
constipation, dyspepsia and flatulence

Evidence-based Practice
Recommendation
• Begin with stool softener + stimulant laxative
(senna preferred); increase dose and/or add
osmotic laxative if necessary
• Avoid bulking agents in those unable to consume
large amounts of fluid
• Consider opioid switching
• Consider adding methylnaltrexone in treatmentresistant OIC

Types/levels of evidence: Likely to be effective; clinical experience, randomized clinical trials
Summary
Patient/physician communication is key to
prevention and recognition of OIC
Consider prophylactic laxatives based on individual
patient needs
There is limited evidence of CAM therapies being
effective
Each patient is unique, as should be their care plan
Questions?
“Overzealous zookeeper Friedrich Riesfeldt of
Paderborn, Germany fed his constipated
elephant Stefan 22 doses of laxative and
more than a bushel of berries, figs and
prunes before the plugged-up pachyderm
finally let it fly, and suffocated the keeper under
200 pounds of poop! Investigators say ill-fated
Friedrich, 46, was attempting to give the ailing
elephant an olive oil enema when the relieved
beast unloaded on him.”
Again, each patient
is unique…treat
them that way
