Fibromyalgia (FM) is a musculoskeletal chronic pain syndrome with various concomitant symptoms like sleep disorders. FM patients are mainly women and menopause might play an important role in the altered processing of somatosensory information. Adverse effects and moderated efficacy of drugs promote treatment discontinuation by patients. Animal models of FM report pain and depression-like behaviors, but none of them have explored sleep disturbance as possible marker in the preclinic diagnostic. The aim of this study was to investigate alterations of the sleep architecture in the reserpine (RES)-induced FM model in ovarectomized (OVX) rats...

The use of pharmacogenomics has become more prevalent over the past several years in treating many disease states. Several cytochrome P450 enzymes play a role in the metabolism of many pain medications including opioids and antidepressants. Noncytochrome P450 enzymes such as methylenetetrahydrofolate reductase (MTHFR) and catechol-O-methyl transferase (COMT) also play a role in the explanation of opioid dosage requirements as well as in response to certain antidepressants. We present the case of a patient with reduced COMT and MTHFR expression treated with leucovorin 10 mg daily for the management of chronic pain...

BACKGROUND: Severe pain reduce quality of life in patients with various diseases, often because chronic morphine therapy results in reduced analgesic effectiveness, or tolerance, leading to escalating doses and distressing adverse effects. Nitric oxide (NO) play a role in morphine tolerance and dependence. OBJECTIVE: Venlafaxine, an antidepressant, is known to modulate nitric oxide (NO) pathway in nervous tissues. In the present study the effect of systemic venlafaxine (VLF) on the development of morphine tolerance and dependence, acute morphine-induced antinociception, and the probable involvement of the L-arginine/NO/cGMP pathway in these effects were investigated in mice...

Millions of patients take antidepressant medications in the United States for the treatment of depression or anxiety disorders. Some antidepressants are prescribed off-label to treat problems such as chronic pain, low energy, and menstrual symptoms. Antidepressants are a broad and expansive group of medications, but the more common drug classes include tricyclic antidepressants, selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, and monoamine oxidase inhibitors. A miscellaneous or "atypical" category covers other agents...

Neuropathic pain, comprising a range of heterogeneous conditions, is often severe and difficult to manage, and this may result in a chronic condition that negatively affects the overall functioning and quality of life in patients. The pharmacotherapy of neuropathic pain is challenging and for many patients effective treatment is lacking; therefore, evidence-based recommendations are essential. Currently, there is general agreement on which drugs are appropriate for the first-line treatment of neuropathic pain, whereas debate continues regarding second- and third-line treatments...

Hideaki Obata
Tricyclic antidepressants and serotonin noradrenaline reuptake inhibitors are used to treat chronic pain, such as neuropathic pain. Why antidepressants are effective for treatment of neuropathic pain and the precise mechanisms underlying their effects, however, remain unclear. The inhibitory effects of these antidepressants for neuropathic pain manifest more quickly than their antidepressive effects, suggesting different modes of action. Recent studies of animal models of neuropathic pain revealed that noradrenaline is extremely important for the inhibition of neuropathic pain...

Chronic pain is a complex and debilitating condition associated with a large personal and socioeconomic burden. Current pharmacological approaches to treating chronic pain such as opioids, antidepressants and anticonvulsants exhibit limited efficacy in many patients and are associated with dose-limiting side effects that hinder their clinical use. Therefore, improved strategies for the pharmacological treatment of pathological pain are urgently needed. G-protein coupled receptors (GPCRs) are ubiquitously expressed on the surface of cells and act to transduce extracellular signals and regulate physiological processes...

Tension-type headache (TTH) is the most common type of chronic recurring head pain. It can occur twice as often in women as in men. It is the most common type of headache. Its lifetime prevalence is 30% to 78% in the general population. TTH treatment should be multilevel. It often consists of taking pain medication, muscle relaxants, antidepressants, using biofeedback therapy, acupuncture, and attending behavioral therapy. Several clinical trials also suggest that botulinum toxin (BTX) may be an effective treatment option for such patients...

Voltage-gated sodium (Na(+)) channels are expressed in virtually all electrically excitable tissues and are essential for muscle contraction and the conduction of impulses within the peripheral and central nervous systems. Genetic disorders that disrupt the function of these channels produce an array of Na(+) channelopathies resulting in neuronal impairment, chronic pain, neuromuscular pathologies, and cardiac arrhythmias. Because of their importance to the conduction of electrical signals, Na(+) channels are the target of a wide variety of local anesthetic, antiarrhythmic, anticonvulsant, and antidepressant drugs...

Setting: There are no studies that exist within the primary care setting that address optimal opioid therapy in osteoarthritis patients. In light of the recently released US Centers for Disease Control and Prevention guidelines on opioid use in chronic noncancer pain, there is a pressing need to better characterize the effectiveness of long- and short-acting opioids. Objective: To examine the effectiveness of short-acting opioids (SAO) vs long-acting opioids (LAO) and combination therapies (SAO and LAO) for treating chronic osteoarthritis pain in a retrospective trial...

Primary burning mouth syndrome (BMS) is an oral mucosal disorder that is characterized by a chronic and often debilitating intraoral burning sensation for which no localized or systemic cause can be found. BMS most commonly affects postmenopausal women. The pathophysiology of primary BMS is not well understood. Diagnosing BMS can prove to be challenging. BMS patients can also pose a therapeutic challenge to clinicians who are consulted to evaluate these patients. Most commonly used therapies include tricyclic antidepressants, α-lipoic acid, clonazepam, and cognitive-behavioral therapy...
