Duloxetine for the management of fibromyalgia syndrome
Fibromyalgia syndrome (FMS) is a widespread pain condition associated with a wide range of additional symptoms including fatigue, insomnia, depression, anxiety and stiffness. Duloxetine is one of three medications currently FDA approved for use in FMS management. Duloxetine is a mixed serotonin and norepinephrine reuptake inhibitor (SNRI) that functions by increasing central nervous system levels of serotonin and norepinephrine. This review is a primer on use of duloxetine in FMS management and includes information on pharmacology and pharmacokinetics, a review of the three duloxetine FMS treatment trials currently in publication, a discussion of the safety and tolerability of duloxetine, and patient-focused perspectives on duloxetine use in FMS management. Duloxetine has proven efficacy in managing pain and mood symptoms in adult FMS patients with and without major depressive disorder. However, due to side effects, duloxetine must be used with caution in patients with fatigue, insomnia, gastrointestinal complaints, headache, cardiovascular disease, bleeding-risk, and in those 24 years of age and younger due to risk of suicidality. Duloxetine use should be avoided in patients with liver disease or alcoholics. As with all medications, duloxetine is best used as part of an individualized regimen that includes nonpharmacologic modalities of exercise, education and behavioral therapies
Milnacipran for the management of fibromyalgia syndrome
Fibromyalgia syndrome (FMS) is a widespread pain condition associated with fatigue, cognitive dysfunction, sleep disturbance, depression, anxiety, and stiffness. Milnacipran is one of three medications currently approved by the Food and Drug Administration in the United States for the management of adult FMS patients. This review is the second in a three-part series reviewing each of the approved FMS drugs and serves as a primer on the use of milnacipran in FMS treatment including information on pharmacology, pharmacokinetics, safety and tolerability. Milnacipran is a mixed serotonin and norepinephrine reuptake inhibitor thought to improve FMS symptoms by increasing neurotransmitter levels in descending central nervous system inhibitory pathways. Milnacipran has proven efficacy in managing global FMS symptoms and pain as well as improving symptoms of fatigue and cognitive dysfunction without affecting sleep. Due to its antidepressant activity, milnacipran can also be beneficial to FMS patients with coexisting depression. However, side effects can limit milnacipran tolerability in FMS patients due to its association with headache, nausea, tachycardia, hyper- and hypotension, and increased risk for bleeding and suicidality in at-risk patients. Tolerability can be maximized by starting at low dose and slowly up-titrating if needed. As with all medications used in FMS management, milnacipran works best when used as part of an individualized treatment regimen that includes resistance and aerobic exercise, patient education and behavioral therapies
