CONFLICT OF INTEREST STATEMENT:
Steven Smith, NP has in years past been on the speaker bureau for Pfizer Inc though not currently. This CE activity was compiled without the aid of any pharmaceutical company. The medications and products mentioned in this activity will be presented in a fair and balanced way.No ink pens or coffee cups were received in exchange for endorsement of any pharmaceutical product mentioned in this presentation.

Is it a mental condition or is it all in their heads?
Is it an inflammatory, rheumatologic problem?
Is it an illness of the central nervous system?
FMS is thought to be an illness of the
CENTRAL NERVOUS SYSTEM
And even more, an illness of the
NEURO-ENDOCRINE SYSTEM
FMS is thought to be one of the many
CENTRAL SENSITIZING SYNDROMES
What is CENTRAL SENSITIZING SYNDROME?
Afferent (conducting inward) sensory input into
THE DORSAL HORN GANGLION
of the spinal column overwhelm the
GATED PROTECTIVE MECHANISMS
so that you get a
WIND-UP PHENOMENON.
What is a WIND-UP PHENOMENON?
It is NEURON HYPEREXCITABILITY with a LOW DISCHARGE THRESHOLD that worsens with each sensory input (pain, touch, movement, any sensory input). This creates an EXAGERATED DISCOMFORT in people with CENTRAL SENSITIZATION SYNDROME.
FMS is thought to be one of several CENTRAL SENSITIZING SYNDROMES.
Others include:
IRRITABLE BOWEL SYNDROMEIRRITABLE BLADDER SYNDROME CHRONIC PELVIC PAINCHRONIC FATIGUE SYNDROMECHRONIC T M JCHRONIC HEADACHERESTLESS LEG SYNDROME
THERE IS OFTEN OVERLAP AMONG THESE CONDITIONS
Also overlapping with FMS are a higher prevalence of coexisting psychopathology:
DepressionGAD/Panic Disorder (responds best to FMS Tx)PTSD (responds worse to FMS Tx)Bipolar Disorder (responds worse to FMS Tx)InsomniaOCD
Pain pathways are a two-way street.
There are AFFERENT, conducting inward, ascending pain pathways,
(Pain towards the brain) or (Pain on a train trying to gain toward the brain)
ANDAmeliorating, inhibitory, descending pain pathways.
(Drain the pain from the brain) or(Train the pain to wane)
Some of the neurotransmitters involved in the ASCENDING pain pathways are:
Substance PGlutamate and other excitatory amino acidsNeurotrophinsNerve Growth FactorBrain Derived Neurotrophic Factor
These are found in higher levels in the CEREBRAL SPINAL FLUID of patients with Fibromyalgia
Some of the neurotransmitters involved in the DESCENDING pain pathways that inhibit pain are:
NorepinephrineSerotonin
The metabolites of these were found to have LOWER levels in the Cerebral Spinal Fluid of patients with Fibromyalgia.
! WAIT !I THOUGHT PAIN WAS A BRAIN THING
In one FMS study, they apply painful stimuli to both FMS patients and a normal control group while performing an MRI observing the increased activity in the areas of the brain related to pain.
It took only half of the painful stimuli to light up these brain areas in the FMS patients than the control group.
The FMS patients have an increase in the gain or sensitivity on their CB radios OR have an increased volume control on their MP3 players of pain.
So, what does this have to do with PHARMACOLOGY?To treat FMS appropriately, you must understand:The Neurotransmitters you want to increase and decrease.The Receptors you want to block.The Neurons that you want to control hyperexcitability.The ascending, descending, and brain pathophysiology of the CNS of the FMS patient.If you understand this you will also understand what pain ameliorating therapies NOT to use.
TWO GREAT TRUTHS
You will not adequately treat what you cannot diagnose.Richard Sobel, MD, mentor
If you do not know how to diagnose Fibromyalgia then this pharmacology lecture is useless.Steven Smith, NP, mentee
FIBROMYALGIA is a diagnosis of EXCLUSION.
That is why FMS is a Syndrome and not a Disease. There is no specific test for FMS.
Diagnosing FMS take the good old fashioned hard work of a good HISTORY AND PHYSICAL EXAM(i.e.. SOAP)

A. TREATING FIBROMYALGIA PAINDo you treat all pain the same?Chest wall pain-NSAIDsRib fracture-NarcoticsGout-Steroids, NSAIDsMigraine-TriptansPost-op pain-NarcoticsDPN/PHN-Antiepil., SNRIs,TCAsOr, you can shoot a fly with a shotgun and give them Lortab. NPs are more sophisticated that that.(5 min. to prescribe narcotics, 30 min. to explain and treat without narcotics.)
3 TYPES OF PAIN1. Peripheral Pain (Nociceptive):Rib Fx, OA/RA, Gout, Trauma, Post-op2. Neuropathic (Damaged/entrapped nerves):DPN, PHN3. Central Pain (Non-Nociceptive):FMS, IBS, Ch. Pelvic Pain, other CSSs
Can someone with RA, DPN, and drop a brick on their foot AND have Fibromyalgia at the same time?
A. TREATING FIBROMYALGIA PAINBecause we now know more about the pathophysiology of Fibromyalgia pain, we will target our approach:
1. Target ASCENDING pain pathways
2. Target inhibitory, DESCENDING pathways
Pain pathways are a two-way street.
There are AFFERENT, conducting inward, ascending pain pathways,
(Pain towards the brain) or (Pain on a train trying to gain toward the brain)
ANDAmeliorating, inhibitory, descending pain pathways.
(Drain the pain from the brain) or(Train the pain to wane)
A. TREATING FIBROMYALGIA PAIN1. Target ASCENDING pain pathways. HOW?
Decrease spinal neuron hyperexcitability with anticonvulsantsa. -2- (alpha-2-delta) ligand anticonvulsants1. Pregabalin (Lyrica) FDA approved for Fibromyalgia2. Gabapentin (Neurontin)b. Other anticonvulsant/antiepileptic drugs
How does pregabalin (Lyrica) and gabapentin work?They bind to the -2- protein on the neuron that has voltage gated channels. A calcium ion has to go back through the gate before certain neurotransmitters can be released from the neuron.
How does Pregabalin (Lyrica) and gabapentin work?(continued)If you decrease the influx of the calcium ions, you decrease the release of certain neurotransmitters into the synaptic gap, therefore decreasing the hyperexcitability of the neuron (seizure control) and, in this case, reduce the level of Substance P and Glutamate that play a role in pain processing and decrease the wind-up phenomenum in the pain sensing neurons.
A. TREATING FIBROMYALGIA PAIN2. Target inhibitory, DESCENDING pain pathways. HOW?a. Raise Serotonin-Norepinephrine levels
1. Serotonin-Norepinephrine Reuptake Inhibitorsa. Venlafaxine (Effexor), Desvenlafaxine (Pristiq)b. Duloxatine (Cymbalta) FDA approved for FMSc. Milnacipran (Savella) FDA approved for FMS, inhibits Norepinephrine reuptake with a 3 fold higher potency that serotonin.
A. TREATING FIBROMYALGIA PAIN2. Target inhibitory, DESCENDING pain pathways. HOW?a. Raise Serotonin-Norepinephrine levels
2. Tricyclic Antidepressants (TCAs)a. Amitriptylline (Elavil)b. Nortriptylline (Pamelor)c. Imipramined. Others
A. TREATING FIBROMYALGIA PAIN2. Target inhibitory, DESCENDING pain pathways. HOW?a. Raise Serotonin-Norepinephrine levels
3. Muscle Relaxersa. Cyclobenzeprine (Flexeril)
A. TREATING FIBROMYALGIA PAIN2. Target inhibitory, DESCENDING pain pathways. HOW?a. Raise Serotonin-Norepinephrine levels
4. Tramadol (Ultram, Ultram ER, Ultracet) Has SNRI properties as well as weak (mu) opioid-receptor agonist properties
5. Exercise Endorphins are pain inhibitors
A. TREATING FIBROMYALGIA PAIN2. Target inhibitory, DESCENDING pain pathways. HOW?a. Raise Serotonin-Norepinephrine levels
HOW DO SNRIs WORK?Mechanism of action is unknown
DESCENDING PAIN CIRCUITSHypothalamus Periaquaductal Gray Rostral DorsolateralVentral PontineMedulla Tegmentum(serotonergic pathway) (noradrenergic pathway) Dorsolateral Funiculus(SNRIs put the Fun in the Funiculus)
A. TREATING FIBROMYALGIA PAIN2. Target inhibitory, DESCENDING pain pathways. HOW?a. Raise Serotonin-Norepinephrine levelsHOW?
If you can reduce the re-uptake of these neurotransmitters back into the neuron, it leaves more neurotransmitter in the synaptic gap leading to pain inhibition, same as with the antidepressant/antianxiety effect of SNRIs.
Pain pathways run through parts of the brain that tell us where the pain is and the intensity of the pain BUT,
Some of the pain pathways run through the areas of the brain such as the amygdala that are related to the affective domain or the emotional response to pain.
This leads us to the second aspect of the treatment of FIBROMYALGIA PAIN.
P PLAN
THE TREATMENTOF FIBROMYALGIA INVOLVES:
A. Treating Fibromyalgia Pain
B. Treating Anxiety and Depression
C. Improve Sleep Architecture
B. TREAT ANXIETY AND DEPRESSION1. Raise Serotonin-Norepinephrine levelsa. SNRIs1. Venlafaxine (Effexor) Cheaper, generic2. Duloxatine (Cymbalta) FDA approved for FMS and anxiety and depression3. Milnacipran (Savella) FDA approved for FMS, inhibits Norepinephrine reuptake with a 3 fold higher potency that serotonin. You need the serotonin reuptake inhibition to treat anxiety.
B. TREAT ANXIETY AND DEPRESSION1. Raise Serotonin-Norepinephrine levels
b. Tricyclic Antidepressants (TCAs)
Remember: TCAs are too anticholenergic and sedation at high enough doses to treat anxiety and depression
B. TREAT ANXIETY AND DEPRESSION1. Raise Serotonin-Norepinephrine levels2. Anti-Epileptic Drugsa. Pregabalin (Lyrica) FDA approved for FMS, Seizure d/o,PHN, DPN, and in Europe approved for anxiety.b. Gabapentin (Neurontin)
c. Valproaic Acid (Depakote)d. Carbamazepine (Tregretol) both used for years for mood disorders
B. TREAT ANXIETY AND DEPRESSION3. What NOT to use:a. Benzodiazepines They increase depression and increase pain scores.b. Narcotics Kills a fly with a shotgun.Morpheus the Greek god of dreams
The Goal of Treating FMS: ECONOMIC 101Try to get the pain scores from 6-7/10 to 2-3/10 so they can return to work so they can pay taxes. People addicted to benzos and narcotics tend to take more taxes than they pay in as a rule.
P PLAN
THE TREATMENTOF FIBROMYALGIA INVOLVES:
A. Treating Fibromyalgia Pain
B. Treating Anxiety and Depression
C. Improve Sleep Architecture
C. IMPROVE SLEEP ARCHITECTURE
80% of FMS patients report Non-Restorative Sleep.
Why do we want to improve sleep architecture?
C. IMPROVE SLEEP ARCHITECTUREFMS polysomnographic studies show abnormalities in sleep continuity as well as sleep architecture.a. Decreased REM sleep with FMSb. Increased awakenings with FMSc. Abnormal alpha wave intrusions in non-REM which is found to worsen pain in sleep with FMSd. Stage 4 or Delta wave sleep is where many restorative hormones are activated like Growth Hormone. This leads to the fibrositis symptom complex causing non-restorative sleep.
IMPROVE SLEEP ARCHITECTURE
So, poor sleep increases pain and fibrositis symptoms.
That is why Fibromyalgia is thought to be an illness of the NEURO-ENDOCRINE SYSTEM.
C. IMPROVE SLEEP ARCHITECTURE
1. Antiepileptic Drugs Improve pain and sleepa. Pregabalin (Lyrica)1. Has a sedative effect2. Enhances slow wave delta sleepb. Gabapentin (neurontin)
C. IMPROVE SLEEP ARCHITECTURE
2. Tricyclic Antidepressants (TCAs) Improve pain, depression and sleep.a. Amitriptylline (Elavil)b. Imipramine (Tofranil)c. Many others
C. IMPROVE SLEEP ARCHITECTURE
3. Non-Benzodiazepine Sedatives Improve sleep.a. Zolpidem (Ambien)b. Zaleplon (Sonata)c. Eszopiclone (Lunesta)d. DO NOT use benzos
4. Teach sleep hygiene5. Treat depression and anxiety6. Exercising/Stretching not within 3 hours of HS
