3OBJECTIVES
- Overcome the barriers to treating pain well
- Think of chronic pain as a disease
- Realize that pain is undertreated in the USA
- Know safe and effective Rx for pain
- Learn how to prescribe methadone or levorphanol
for nerve or complex pain
4Definitions
- Chronic pain persistent (weeks, months, yrs)
- present at least 12 hr daily
- intensity at least 5 on a 0-10 scale
- Nociceptive Pain somatic or skeleto-muscular
visceral pain - Neuropathic Pain pain from CNS or peripheral
nerve injury, difficult to relieve - Complex Chronic Pain a mix of pain types, common
in cancer, in postop. conditions, and in trauma -
5Barriers to Treating Chronic Pain
- Education
- Experience
- Fear of Regulators
- Fear of Addicting Patients
- Fear of Opioid use in the Dying
6Education, Experience, and Regulators
- Doctors and nurses in the past were given little
education and training about pain, and
consequently are uncomfortable in prescribing
opioids for treating pain, especially chronic
pain. - Changing attitudes and accepting advances in pain
Rx may be difficult for many doctors and nurses. - Fear of DEA, regulatory boards is excessive
7Fear of Addiction
- The risk of addiction is over-stated.
- The vast majority of patients with chronic pain
are not addicts. - The risk of becoming addicted is estimated at
1-3 in the general pain population when there is
no history of prior substance-abuse. - 80 of addicts have inherited a genetic brain
disorder, which is a life-long problem. - Normal pain patients follow the rules.
- Addicts bend and break the rules.
8Addiction
- The problem in addiction and with substance
abusers is not with the opioid, alcohol,etc .It
lies within the abusers Brain. - The reward center in the brain of addicts is not
supplied with enough dopamine to enable addicts
to feel pleasure as normal persons do.
9Addiction
- The addict seeks an activity or substance which
boosts dopamine action at the reward center in
the brain, which makes him feel good ( normal
or better than normal). - After the boost subsides, the addicts craves that
dopamine high compulsively, even though the
activity or substance may be damaging to him.
10Opioids and Respiratory Depression
- Patients receiving opioids for chronic pain and
dyspnea tolerate large opioid doses without
serious respiratory depression, when titrated
appropriately. - In contrast, opioid-naïve patients should be
closely observed when they receive opioids, as
their respiratory center has not yet developed
tolerance to opioids.
11Overcome the Fear of Using Opioids in the Dying
- Serious resp. depression is rare in patients
being treated for chronic pain. If oversedation
does occurs, sleepiness occurs first. Observe
closely, and if stable, hold opioid until awake,
then resume at a lower dose and/or dosing
interval, or change the opioid. - Evidence-based studies indicate that judicious
opioid use in the dying does NOT hasten death,
but allows them to live in comfort until they
die. - The benefits of opioids greatly out-weigh risks.
12Morphine Approved for Chronic Refractory Dyspnea
- The American Thoracic Society and the American
College of Physicians approve the use of morphine
and other opioids for managing chronic refractory
dyspnea. - The Longitudinal Pattern of Response When
Morphine is Used to Treat Chronic Refractory

13How to Manage Pain in Seriously Ill Patients
Who Might Die
- Difference between Acute and Chronic Pain
- Assessing Chronic Pain
- Treatment of Chronic Complex Pain
- Specific Opioids
- Workshop on Equianalgesic Opioid conversion
14Acute Pain
- Pathway for transmission of acute pain in spinal
cord and CNS is conventional. - Duration of acute pain is short.
- Endorphins and enkephalins are released by CNS to
block pain perception by activating mu and kappa
receptors in the dorsal horn of the spinal
cord.All of the opioids are effective to relieve
acute pain in this way.
15Changing from Acute Painto Chronic Pain
- Acute pain causes release of the neurotransmitter
glutamate in the dorsal horn of the spinal cord. - Glutamate binds to AMPA receptors in cells of the
dorsal horn, which triggers pain signals to the
CNS - When AMPA receptors are saturated by excess
glutamate, normally inactive N-methyl-D-aspartate
(NMDA) receptors in the spinal cord become
activated by the excess glutamate. - This begins the change from acute to chronic pain
16Acute and Chronic PainBrookoff,D1) Chronic
Pain A New Disease? Hosp Pract 35(6)
Minneapolis,MN 45-59
17Consequences of N-Methyl-D-Aspartate Receptor
Activation
- Windup
- Neural Remodeling
- Activation of Neurokinin-1 Receptors
- Afferent becomes Efferent
- Neurogenic Inflammation
18Windup
- Less glutamate is required to transmit pain
- More anti-nociceptive input required to stop it
- Endorphins cannot keep up with demand
- Pain relievers lose their effectiveness
- Result More intense pain, harder to relieve
19Neural Remodeling
- Activation of NMDA receptors cause neural cells
to sprout new connective endings - adds new dimensions to old sensations
- emotional component of pain can increase
- new connections channel signals to the reticular
activating system of the brain - RESULT Diffuse, hard to localize pain
20Activation of NK-1 Receptors
- NMDA receptor activation causes nociceptors to
release the peptide neurotransmitter Substance P - Substance P binds to Neurokinin-1 receptors
- This amplifies the pain signal
- Stimulates nerve growth and regeneration
21Substance P
- Induces production of the c-fos oncogene
- the biochemical footprint for chronic pain
- marker for central hyper-sensitization
- C-fos
- levels go higher up the spinal cord with
persistence of pain - reaches the thalamuspain is untreatable
- Pain is no longer confined to the original site
in some patients - Detected in fibromyalgia in lab studies
22Afferent becomes Efferent
- NMDA receptor activation causes some afferent
neurons to carry signals backwards to
nociceptors, which can establish a dorsal root
pathological reflex - Substance P is released at the periphery causing
inflammation and promotes the cyclic nature of
chronic pain
23Neurogenic Inflammation
- A tissue reaction caused by Substance P and nerve
growth factor, affecting synovia and other
connective tissue. - Doesnt depend on granulocytes or lymphocytes
- Substance P causes de-granulation of mast cells,
releases bradykinin, nitric acid.
24Neuropathic Pain
- Damage to sensory nerves
- can cause neuropathic pain syndromes
- insensitive to anti-nociceptive suppression by
conventional opioids. - After tissue injury
- A Fibers- large myelinated nerves that carry
touch sprout new terminal branches - These synapse with pain-sensing cells in the
OUTER dorsal horn which lack opioid receptors,
thus endogenous and exogenous opioids are
ineffective - examples of pain poorly responsive to opioids are
phantom limb and diabetic neuropathy
25Assessing Chronic Pain
-
- Detailed description of pain ( from patient,
caregiver, staff ) is it somatic, visceral,
neuropathic, or mixed? Location? Intensity? - What makes it better or worse
- Effect on emotional, social status
- How much impairment of function?
- Review diagnostic and lab data
- Reassess often to adjust treatment
26Pain near the End-of-Life
- Chronic pain more complex and difficult to
treat than acute pain - Somatic and Visceral pain (Nociceptive ) usually
opioids and adjuvants are effective - Neuropathic pain NMDA-receptor blocking opioids
( levorphanol, methadone) or ketamine work best.
Adjuvants are helpful, often over-rated.
27Treating Pain with Opioids
- Use the World Health Organization
- 3-step analgesic ladder
- Step 1 Mild analgesics APAP, NSAIDs
- Step 2 Moderate analgesics Codeine,
Tramadol Hydrocodone/APAP, Oxycodone/APAP - Step 3 Strong Opioids
28WHO 3-stepLadder

Morphine Hydromorphone Methadone Levorphanol Fenta
nyl Oxycodone Adjuvants
2 moderate
A/Codeine A/Hydrocodone A/Oxycodone A/Dihydrocodei
ne Tramadol Adjuvants
1 mild
ASA Acetaminophen NSAIDs Adjuvants
29Morphine
- Usual 1st. choice for moderate, severe pain.
Begin low, 15mg q 3-4 hr. Titrate, reassess
often. - No ceiling amount as long as tolerated.
- Resp. depression rare in chronic pain patients.
- High doses metabolites cause nausea,
- dysphoria, muscle jerks, seizures.
30Dilaudid- hydromorphone
- Beginning dose 2-4 mg q 3-4 hr. Very effective,
similar to MS. - Less nausea. No ceiling. Often used orally for
breakthrough pain and i.v. - No sustained-release form.
- 2 mg 8 mg MS
- Toxicity similar to morphine
31Oxycodone
- Starting oral dose 5-10 mg q 3-4 hr. Very
effective. - Less nausea, less troublesome metabolites. With
ASA and APAP (Percodan, Percocet), ceiling is
limited. - Expensive sustained-release form (Oxycontin), no
ceiling. Watch for illegal diversion. Oxycontin
10,20,40,80 mg. - Liquid concentrate 20mg/ml is useful
sublingually or buccally in the dying, similar to
MS oral concentrate (Roxanol).
32Duragesic (Fentanyl)
- Duragesic patch use care in opioid- naïve
patient, only after pain controlled by
short-acting opioid. One patch used for 72 hr. - Fever increases absorption. Avoid placing patch
on areas without subcut. fat. - 10-12 hr delay in onset and offset due to skin
fat reservoir absorption. - Early tolerance may limit use in severe pain
33 Methadone
- Methadone, a synthetic opioid developed in 1940
has been used worldwide for pain relief. The
development of sustained-action morphine,
oxycodone, and fentanyl in the 80s, relegated
methadone to use mainly in substance-abuse until
recently. Used for neuropathic and complex pain,
it is now easy and safe to convert from morphine
and other opioids to methadone.
34Levorphanol
- The forgotten opioid, an excellent drug,
Levorphanol, like Methadone, was no longer
marketed after 1990. It is available now in 2mg
tablet ( Rorer). Evidence-based study in 2003
effective in relief of neuropathic pain. - Personal experience and published case studies
confirm its value (JPM, 2007, 2009)
35 Levorphanol
- NMDA-receptor blocker and mu-opioid agonist.
Long half-life dose 6,8,or 12 hr - 2 mg tablet equal to 8-15 mg morphine p.o
- Excellent alternative to methadone no stigma no
effect on QTc no effect on cytochrome P450
pharmacokinetics. - Easiest drug to convert to and from methadone.
36Short-acting Opioids to Begin Rx or for
Breakthrough Pain q 3-4hr
- Hydrocodone/ APAP oral tabs and liquid 5-10 mg

41Prescribing Opioids for Chronic Pain- General
Principles
- Use WHO pain ladder to select analgesic
- Around-the-clock, q. 3-4 hr. ( not 4-6 hr)
- Assess frequently, adjust dose to relieve pain
- When pain controlled,add up total opioid taken q.
24hr. Select long-acting opioid q. 12 hr. - Use short-acting opioid for breakthrough pain
prn. - Use one short- and one long-acting
- Reassess to titrate dose q 1-2 days until stable.
42How to Convert From One Opioid to a Different
Opioid
- Add up all the opioids currently prescribed in
the previous 24 hrs. - Use the equi-analgesic tables to convert all
opioids to their oral morphine equivalent in the
previous 24 hrs. - Choose a new opioid, and use the tables to
calculate the 24hr dose of that opioid - Use a long-acting, and a short-acting version
(if available), dosed appropriately for that
opioid
43Equianalgesic Doses if Morphine 10 mg p.o.
- Hydromorphone 2 mg- 2.5 mg ( I use 2.5 mg)
- Oxycodone 5-10 mg ( I use 10 mg)

471 Hydrocodone converted to Morphine
- 15 mg hydrocodone 10 mg oral morphine
- Patient taking 15 mg hydrocodone q 4 hr atc
equals 90 mg/24hr. - 90 mg hydrocodone 60mg morphine/24hr, or 10 mg
morphine orally q 4hr ATC, and titrate up if
needed.
482a Convert Vicodin and Percocet to Fentanyl Patch
- 60 yr male with chronic back pain not helped by
Vicodin 10mg every 4 hr. and by Percocet 10mg 6
times daily - Convert first to morphine equivalent/24hr
- From chart60mg hydrocodone 40mg MS
Oxycocone 60mg 60mg MS - MS equivalent 100 mg/ 24hr.
- Convert to Fentanyl next slide
492b) Convert Morphine (oral) to Fentanyl patch
- Patient is receiving 100 mg oral morphine
equivalent poor relief from pain - Use the conversion chart for morphine to
fentanyl - 100 mg oral morphine 50 mcg/h patch applied
every 72 hr. Onset and offset of effect of
fentanyl is about 10-12 hours.
503a Convert Oral morphine to i.v.Dilaudid
- Oral morphine dose is 360 mg in 24 hr.
- Convert first to oral dilaudid 1 mg dilaudid 4
mg oral morphine divide 360 by 4 90 mg oral
dilaudid. - 1 mg i.v. dilaudid 5 mg oral dilaudid
- Divide 90 mg oral dilaudid by 5 16 mg i.v.
dilaudid in 24 hr. - Quick way Divide Morphine by 20 16 mg
513b Convert iv Dilaudid back to Morphine oral
equivalent
- Dilaudid iv dose in 24 hr 16 mg
- Convert from iv dilaudid to oral dilaudid 1
mg iv 5 mg oral dilaudid 16x5 90 mg - Convert oral dilaudid to oral morphine 1mg oral
dilaudid 4 mg oral morphine - 90 mg oral dilaudid 90 x 4 360 mg oral
morphine/24 hr.
52 4aChronic Neuropathic Pain
- Attorney, age 46 ulnar neuropathy due to
ischemia during long coronary bypass. Pain
lancinating and burning, score 5-7, left forearm
and hand, with interosseus atrophy. - No relief with gabapentin, hydrocodone,
oxycodone. Unable to work effectively. - Convert to Levorphanol from 48 mg MS
equivalent/24 hr
534b Convert to Levorphanol
- From conversion chart, the ratio of morphine to
levorphanol 121 in this case. - 48 mg MS divided by 12 4 mg Lev./ 24 hr
- Patient declined dose 1mg tid allowed bid.
- After day 1, lancinating pain stopped, but
burning persisted. 2 mg q 12 hr relieved his pain
thereafter.
54Prescribing Very-Low Dose Methadone
- New evidence very-low methadone 2.5 mg morning
and night blocks the NMDA receptor effectively,
suggesting that the more controversial higher
doses of methadone can be avoided by using other
strong mu agonist opioids ( morphine, etc) as
needed to control chronic pain. Haloperidol was
effective adjuvant in small dose. - J Pall Med2013,16 ( June)
55Levorphanol or Methadone?
- Levorphanol advantages No stigma, no ECG
prolongation of QTc, predictable half-life, very
few drug interactions. No bad press and drug
industry misinformation. - NMDA-receptor blocker like methadone mu and
kappa agonist like morphine, oxycodone,
hydromorphone. Forgotten!
56 5a Unrelieved back, chest, abdominal pain in
cancer patient
- Current opioids prescribed in past 24 hours
- Fentanyl patch 50 mcg/hr q 72 hr
- Dilaudid 1mg iv x 4 doses 4 mg iv.
- CONVERT to 24hr oral morphine equivalent
- Fentanyl 50mcg/hr 100mg oral MS/24h
- Dilaudid 4 mg x4 x5 80 mg oral MS/24h
- CONVERT to Oxycodone from 180mg MS
575b Converting Morphine- equivalent. to Oxycodone
- From chart,1mg oxycodone1mg morphine
- Patient 180 mg Morphine equiv./ 24hr
- Patient converts to 180mg Oxycodone/24 hr
- Dose Oxycodone ER 90 mg p.o. q 12 hr use Oxy
IR 5 mg q 4 hr prn breakthrough.
585c Convert same patient to Methadone
- Patient was receiving
- Fentanyl patch 50mcg/72 hr
- Dilaudid 1 mg iv x 4 doses 4 mg iv
- Convert to oral morphine equivalent/ 24 hr
- Fentanyl 50mcg 100 mg oral MS/ 24 hr
- Dilaudid 4 mg iv x 4 x 5 80 mg MS/ 24hr
- Convert Methadone from 180 mg MS/24hr
595d Convert Morphine oral equivalent to Methadone
- From the conversion table to and from morphine to
methadone, the ratio of MS to methadone in this
case is 81. - 180 mg oral MS/ 24 hr divided by 8 22.5 mg oral
methadone in 24 hr. - Dose Methadone 7.5 mg orally q 8 hr use oral
dilaudid 2mg q 3-4 hr prn breakthrough pain or
use 2.5 mg methadone q 4 hr prn.
606a Severe Neuropathic Pain Converted to Methadone
- Female, age73, has severe neuropathic pain due to
cancer of tongue. She receives, via PEG, 170 mg
morphine oral concentrate every 3 hr. Oral
morphine equivalent/24 was 170 mg x 8 doses
1,360 mg. Surprisingly, she was physically
active, gardening and driving. Convert Methadone

63 Summary
- The standard of care for the treatment of pain is
changing every year. - Pain, particularly chronic pain, is undertreated
by most physicians. - Non-interventional pain treatment is safe,
effective, and cost-efficient. - Most primary care MDs can treat most patients
with chronic pain, whether malignant or
non-malignant. Mentor is helpful with complex
case. - Palliative Care team can help relieve complex
chronic pain in seriously ill suffering patients.
64Case 1
- 86 yr WF, readmitted from nursing facility
dementia, debility, dehydration, UTI, sacral and
heel decubiti, 3rd hospitalization in 3 mo.
Grimaces and cries out when turned and bathed.
Lortab elixir 5 mg q 6hr not helpful. - Rx parenteral fluids, antibiotics, iv morphine,
haloperidol, wound care, Foley - Sepsis worsens, more agitation, family notified
of decline and asks for comfort care at home with
hospice.
65Palliative Care at Home with or without
Hospicefor Case 1
- Hospice or palliative care team assessment
develop plan of care with MD - Pain Morphine oral conc. 20mg/ml 0.25 ml (5 mg)
buccally q 2-4 hr prn pain titrate up 0.25 ml
stepwise as needed - Haloperidol oral conc. 2mg/ml. 1-2 mg q 4-8 hr
buccally, for agitation or nausea. - Lorazapam oral conc. 2mg/ml 0.5-2.0 mg may or
may not be helpful for anxiety.
66Alternative Rx for Case 1
- Dont use Fentanyl patch until stable pain
control with short-acting opioid- remember
25mcg/hr is equal to 50mg oral morphine/24hr - Oxycodone oral conc. 20mg/ml SL or buccally
- Hydromorphone 2mg tabs(crushed) or oral solution,
1-2mg q 3-4 hr. - Levorphanol 2mg tab (crushed) ½ tab q 8hr subling
or oral conc. 2 mg/ml - Methadone 2.5mg (crushed) or oral conc.q 12hr
67Case 2Lung cancer with spread to Pleura and Ribs
- 61yr WM, Dx 1 mo., seen in Onc. Clinic Pain at
7, aching, sharp with activity and with cough.
Lortab10 q 4-6 hr prn not helping over past 2
wks. - Percocet 5 one or two q 4hr ATC helps after 3
days taking 8 tabs/ 24 hr.(40 mg in 24 hr) - Convert to Oxycontin 20 mg q 12 hr,and 1 Percocet
q 4 hr prn breakthrough pain.
68Case 2 Worsens
- Despite aggressive Rx, he developes mets to liver
and spine pain becomes severe, with somatic,
visceral, and neuropathic elements - Oxycontin increased stepwise, 80 mg q 8hr
- No relief, so Dilaudid by PCA pump, and finally
an intrathecal pump is helpful until he becomes
septic and pump is removed.
69Case 2 near- terminal
- Dilaudid PCA not controlling pain 2 mg/hr plus
20mg demand, for total 68mg/24hr. - Morphine equivalent68 x201,360 mg po
- Convert to Methadone conversion ratio is 20 to
1, so Methadone dose is 68 mg in 24hr - Could dose po 20mg at 6am and 2pm and at 10pm, or
half that dose q 8hr subcut. Reassess often to
adjust dose up or down,
70Case 3End-stage COPD
- 78yr WF, smoker, anxious and fearful, housebound,
oxygen-dependent, on nebs, prednisone, in and out
of hospital with pneumonia, gets frequent bouts
of dyspnea. - She and family are afraid of narcotics
(addiction, hastening death). - Lorazepam helps some with anxiety and
hyperventilation, but sx worsen.
71Case 3 Comfort
- Educating family and patient by nurse and doctor
that benefit of Morphine is great and risk is
very small takes time and diligence - They finally agree with a test dose of 5mg,
either oral conc. or MSIR tab, when in distress
and with nurse present - In 30 min, patient gets calm, more relaxed, with
much better relief of dyspnea, and thereafter she
allowed morphine prn for dyspnea or pain.
72Case 4 Breast Cancer with Spread to Bone and
Liver
- 54 yr BF admitted to Hospice from hospital with
constant mod.severe pain in upper back, rib cage
and upper abdomen. - She was on a Morphine PCA pump, and was
converted to MsContin 90mg q 12hr, with 30mg MSIR
q 4hr prn breakthrough pain. - Over next mo., pain increased despite 600mg
MsContin in 24 hr. Muscle spastic contractions
develop, signalling morphine toxicity Must
rotate to another opioid ( Dilaudid).
73Case 4 Side-effects
- Dilaudid tried orally, then by PCA pump, but
metabolites of Dilaudid cause similar
side-effects, leading to seizures. Must calculate
rotation to another opioid ( Levorphanol) and
stop Dilaudid. Dilaudid dose is equal to 480 mg
oral morphine in 24 hr. Consultant rotates her
to oral Levorphanol. Ratio of MSLev is 201 in
this case, so Lev. dose is 24 mg/ day, or 6mg q
6 hr. Pain reduced, with no adverse effects
