Medication Summary
Drug therapy for TOS can be divided into the following categories:
Nonsteroidal anti-inflammatory agents (NSAIDs)
Class Summary
These agents inhibit inflammatory reactions and pain by decreasing activity of cyclooxygenase, which is responsible for prostaglandin synthesis. NSAIDs may provide pain relief in the patient with TOS.
Naproxen sodium (Anaprox, Naprelan, Naprosyn)
For relief of mild to moderately severe pain; inhibits inflammatory reactions and pain by decreasing activity of cyclooxygenase, which results in decrease of prostaglandin synthesis.
Ibuprofen (Motrin, Advil)
NSAIDs used commonly for patients with mild to moderately severe pain. Inhibits inflammatory reactions and pain by decreasing prostaglandin synthesis.
Analgesics
Class Summary
Pain control is essential to quality patient care. Analgesics ensure patient comfort, promote pulmonary toilet, and have sedating properties, which are beneficial for patients who have sustained trauma or injuries.
Acetaminophen (Tylenol, Feverall, Tempra, Aspirin Free Anacin)
DOC for pain in patients with documented hypersensitivity to aspirin or NSAIDs, with upper GI disease, or who are taking oral anticoagulants.
Oxycodone (OxyContin)
Long-acting form of opioid currently used commonly for severe pain. Start with small dose and increase gradually.
Morphine sulfate (MS Contin, Duramorph, Astramorph)
Effective analgesic with good safety profile and ease of reversibility with naloxone. Various IV doses used; commonly titrated until desired effect obtained.
Oral morphine sulfate includes Avinza, Kadian, and MS Contin. These medications are available in multiple different strengths (15-120 mg).
Fentanyl transdermal patch (Duragesic)
Potent narcotic analgesic with much shorter half-life than morphine sulfate. Excellent choice for pain management and sedation with short duration (30-60 min); easy to titrate. Easily and quickly reversed by naloxone. When using transdermal dosage form, most patients' pain controlled with 72-h dosing intervals; however, some patients may require dosing intervals of 48 h.
Antidepressants
Class Summary
This complex group of drugs has central and peripheral anticholinergic effects, as well as sedative effects. They have central effects on pain transmission. They increase synaptic concentration of serotonin and/or norepinephrine in CNS by inhibiting their reuptake by the presynaptic neuronal membrane.
Other options include milnacipran (Savella), duloxetine hydrochloride (Cymbalta), venlafaxine (Effexor), and bupropion (Wellbutrin).
Nortriptyline (Pamelor)
Has demonstrated effectiveness in treatment of chronic and neuropathic pain.
Amitriptyline (Elavil)
Analgesic for certain chronic and neuropathic pain.
Selective serotonin reuptake inhibitors
Class Summary
These agents may be considered as alternative to TCAs.
Fluoxetine (Prozac)
Antidepressant with potent specific 5-HT uptake inhibition with fewer anticholinergic and cardiovascular adverse effects than TCAs.
Sertraline (Zoloft)
Antidepressant with potent specific 5-HT uptake inhibition with fewer anticholinergic and cardiovascular adverse effects than TCAs.
Paroxetine (Paxil)
Antidepressant with potent specific 5-HT uptake inhibition with fewer anticholinergic and cardiovascular adverse effects than TCAs.
Benzodiazepines
Class Summary
By binding to specific receptor sites, these agents appear to potentiate the effects of GABA and facilitate inhibitory GABA neurotransmission and other inhibitory transmitters. They may act in the spinal cord to induce muscle relaxation.
Clonazepam (Klonopin)
Suppresses muscle contractions by facilitating inhibitory GABA neurotransmission and other inhibitory transmitters.
Anticonvulsants
Class Summary
Use of certain antiepileptic drugs, such as the GABA analogue gabapentin (Neurontin), has proven helpful in some patients with neuropathic pain. Other anticonvulsants (eg, clonazepam, topiramate, lamotrigine, zonisamide, tiagabine) also have been tried in chronic pain.
Pregabalin (Lyrica) can be effective, tolerable, and easy to titrate compared to gabapentin.
Gabapentin (Neurontin)
Has anticonvulsant properties and antineuralgic effects; however, exact mechanism of action unknown. Structurally related to GABA but does not interact with GABA receptors.
