Dysesthesias may be treated as any other dysesthetic pain. Tricyclic antidepressants, such as amitriptyline at 10-25 mg PO qhs, may be tried. If this approach is unsuccessful, anticonvulsants (eg, gabapentin, carbamazepine) often are effective.
A complex group of drugs that have central and peripheral anticholinergic effects, as well as sedative effects. They have central effects on pain transmission, and they block the active re-uptake of norepinephrine and serotonin.
Analgesic for certain chronic and neuropathic pain. Low doses, 10-25 mg qhs, may provide pain relief from burning and tingling occurring at rest but function only as an adjunct to definitive treatment.
Use of certain antiepileptic drugs (AEDs), such as the GABA analogue Neurontin (gabapentin), has proven helpful in some cases of neuropathic pain. Thus, although unstudied, a trial of such an agent might conceivably provide analgesia for symptomatic neuropathy. Used for dysesthesias not controlled with definitive treatment plus tricyclic antidepressants (or in patients unable to take tricyclic antidepressants).
Neuromembrane stabilizer useful in pain reduction with dysesthetic pain. Has antineuralgic effects; however, exact mechanism of action is unknown. Structurally related to GABA, but does not interact with GABA receptors.
Structural derivative of GABA. Mechanism of action unknown. Binds with high affinity to alpha2-delta site (a calcium channel subunit). In vitro, reduces calcium-dependent release of several neurotransmitters, possibly by modulating calcium channel function. FDA approved for neuropathic pain associated with diabetic peripheral neuropathy or postherpetic neuralgia and as adjunctive therapy in partial-onset seizures.
Serotonin-Norepinephrine Reuptake Inhibitors
These agents inhibit neuronal serotonin and norepinephrine reuptake.
Description Indicated for diabetic peripheral neuropathic pain. Potent inhibitor of neuronal serotonin and norepinephrine reuptake.
