PURPOSE: The aim of this study was to evaluate the potential of hair analysis to monitor medication adherence in headache patients undergoing chronic therapy. For this purpose, the following parameters were analyzed: the detection rate of 23 therapeutic drugs in headache patients' hair, the degree of agreement between the self-reported drug and the drug found in hair, and whether the levels found in hair reflected the drug intake reported by the patients. METHODS: The study included 93 patients suffering from primary headaches declaring their daily intake of at least one of the following drugs during the 3 months before the hair sampling: alprazolam, amitriptyline, citalopram, clomipramine, clonazepam, delorazepam, diazepam, duloxetine, fluoxetine, flurazepam, levomepromazine, levosulpiride, lorazepam, lormetazepam, mirtazapine, paroxetine, quetiapine, sertraline, topiramate, trazodone, triazolam, venlafaxine, and zolpidem...

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most disabling and demoralizing problems that arise for cancer survivors. When investigating symptoms of numbness, tingling, or pain in the extremities, it is critical to determine whether the problem is neuropathic, somatic, or mixed. If the diagnosis is CIPN, it is important to weigh the potential benefits and harms of possible treatment options, and to devise an evidence-based multimodality treatment program. Such programs may include mixtures of opioid and nonopioid adjunctive medications, based on evidence from CIPN trials, and also extrapolation from trials in patients with other neuropathic pain syndromes-although such extrapolating must be done with caution, since other syndromes sometimes respond to agents that CIPN does not respond to...

BACKGROUND: Various drugs are administered for the management of chemotherapy-induced peripheral neuropathy (CIPN) in Japan. However, there have been no surveys undertaken to identify these drugs or their frequency of prescription. Therefore, we administered a questionnaire survey to the diplomates of the Subspecialty Board of Japanese Society of Medical Oncology (JSMO) to investigate the frequency of administration of different drugs for the management of CIPN in Japan. METHODS: We investigated the use of vitamin B12, antiepileptic agents such as pregabalin, duloxetine, antidepressants other than duloxetine, non-steroidal anti-inflammatory drugs (NSAIDs), opioids and the Kampo compound goshajinkigan in a questionnaire employing a three-step scale wherein A implies routine or prophylactic administration, B implies occasional administration and C implies infrequent administration...

Idiosyncratic hepatotoxicity is one of the most common reasons for an approved drug being restricted. This article focuses on hepatotoxicity of selected and recently introduced agents, such as, tyrosine kinase inhibitors, monoclonal antibodies, novel oral anticoagulants, newer antiplatelets, antibiotics, anti-diabetics, anti-epileptics, anti-depressants, anti-psychotics and anti-retrovirals. Overall, the incidence of clinically relevant hepatotoxicity from newer agents seems to be lower than that of the older agents...

BACKGROUND: In major depressive disorder (MDD), treatment persistence is critical to optimize symptom remission, functional recovery, and health care costs. Desvenlafaxine tends to have fewer drug interactions and better tolerability than other MDD drugs; however, its use has not been assessed in the real world. OBJECTIVE: The aim of the present study is to compare medication persistence and concomitant MDD drug use with branded desvenlafaxine (Pristiq(®)) compared with antidepressant drug groups classified as 1) branded selective serotonin reuptake inhibitors (SSRIs; ie, escitalopram [Lexapro™]) and selective serotonin-norepinephrine reuptake inhibitors (SNRIs; ie, venlafaxine [Effexor(®)], duloxetine [Cymbalta(®)]) and 2) generic SSRIs/SNRIs (ie, escitalopram, citalopram, venlafaxine, fluvoxamine, fluoxetine, sertraline, paroxetine, and duloxetine)...

Deficits in recognition of facial expressions of emotion (RFEE) play a central role in the manifestation of anxiety disorders (AD). We systematically reviewed the literature to determine effects of drugs used in AD treatment on RFEE, based on outcomes of accuracy rate, reaction time, and intensity. Electronic databases, including Pubmed, PsycINFO, and Scielo, were used without time constraints. Twenty-six clinical/experimental studies on healthy subjects, focusing on 11 drugs, published in English, Portuguese, and Spanish, were selected...

BACKGROUND: Neuropathic pain is a common side-effect of chemotherapy. Although precise mechanisms are unclear, oxidative stress and mitochondrial damage are involved. We investigated whether the mitochondria targeted antioxidant, MitoVitE, provided better protection against paclitaxel-induced mitochondrial damage in rat dorsal root ganglion (DRG) cells, than a non-targeted form of vitamin E, Trolox. We also determined whether MitoVitE, compared with duloxetine, could limit paclitaxel-induced mechanical hypersensitivity in rats...

Placebo response in the clinical trial setting is poorly understood and alleged to be driven by statistical confounds, and its biological underpinnings are questioned. Here we identified and validated that clinical placebo response is predictable from resting-state functional magnetic-resonance-imaging (fMRI) brain connectivity. This also led to discovering a brain region predicting active drug response and demonstrating the adverse effect of active drug interfering with placebo analgesia. Chronic knee osteoarthritis (OA) pain patients (n = 56) underwent pretreatment brain scans in two clinical trials...

Duloxetine (DXT), a serotonin/norepinephrine reuptake inhibitor, is widely used for the treatment of major depressive disorders. In the present study, we investigated the neuroprotective effect of pre-treated DXT in the hippocampal CA1 region following transient global cerebral ischemia. Pre-treatment with 40mg/kg DXT protected pyramidal neurons in the CA1 region from ischemia-reperfusion injury. In addition, pre-treatment with DXT reduced ischemia-induced activations of microglia and astrocytes in the ischemic CA1 region...

BACKGROUND/AIMS: To investigate the potential inhibitory effects of 18 clinically available antidepressants on acetylcholine (ACh)-induced contractions in guinea pig urinary bladder smooth muscle (UBSM) in order to predict whether they may induce voiding impairment. METHODS: Concentration-response curves for ACh-induced contractions in guinea pig UBSM strips were obtained in the absence or presence of selected antidepressants. When inhibitory effects indicated competitive antagonism, pA2 values against ACh were calculated and compared to plausible antidepressant blood concentrations...

P2X4 receptors (P2X4R) are a family of ATP-gated non-selective cation channels. We previously demonstrated that activation of P2X4R in spinal microglia is crucial for neuropathic pain, a highly debilitating chronic pain condition, suggesting that P2X4R is a potential therapeutic target for treating neuropathic pain. Thus, the identification of a compound that has a potent inhibitory effect on P2X4R is an important clinical challenge. In the present study, we screened a chemical library of clinically approved drugs and show for the first time that duloxetine, a serotonin and noradrenaline reuptake inhibitor, has an inhibitory effect on rodent and human P2X4R...

Early stress is a significant risk factor for the onset of mood disorders such as depression during adulthood. Impairments in cognitive flexibility mediated by prefrontal cortex (PFC) dysfunction are increasingly recognized as important etiological and pathological factors in the development of depression. Our previous study demonstrated that social defeat stress during early adolescence produced delayed deficits in cognitive flexibility in adult mice. The potential molecular mechanisms underlying these long-term consequences remain unclear...

Major depressive disorder (MDD) and irritable bowel syndrome (IBS) frequently co-occur, yet treating their comorbid presentation is challenging. Low-dose tricyclic antidepressants are efficacious for IBS, but higher doses to treat depressive symptoms present tolerability problems, whereas selective serotonin reuptake inhibitors are more tolerable but show inconsistent efficacy for IBS. If efficacious, serotonin-norepinephrine reuptake inhibitors like duloxetine would provide a useful alternative. We explored efficacy, tolerability, and time to onset of action of duloxetine in comorbid IBS-MDD in an open-label, 12-week trial...

In the present study, we investigated whether restoring descending noradrenergic inhibitory tone can attenuate pain in a PD rat model, which was established by stereotaxic infusion of 6-hydroxydopamine (6-OHDA) into the bilateral striatum (CPu). PD rats developed thermal and mechanical hypersensitivity at the 4th week after surgery. HPLC analysis showed that NE content, but not dopamine or 5-HT, significantly decreased in lumbar spinal cord in PD rats. Additional noradrenergic depletion by injection of N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4) aggravated pain hypersensitivity in PD rats...
