Abstract: Migraine is a primary headache disorder characterized by recurrent episodes of headache associated with gastrointestinal, neurologic, and autonomic symptoms. Some evidence in literature suggests that the melatonergic system possibly plays an important role in the pathogenesis of migraine. Few studies have been performed on the use of melatonin as an antimigraine agent. Other than amitriptyline, few antidepressants have been found to be efficacious for migraine prophylaxis. Among antidepressants, agomelatine has a novel neurochemical mechanism. It is an melatonin receptor 1 and melatonin receptor 2 melatonergic receptor agonist and a selective antagonist of the 5-hydroxytryptamine (serotonin) receptor 2C receptors.
Abstract: Somatoform disorder is a relatively common and severe disorder for which pharmacotherapy has been minimally studied. We report a case of 30-year-old woman with treatment-resistant somatoform disorder that was successfully treated with add-on treatment of gabapentin. Our result showed that gabapentin 1800 mg/day could be tried in case of treatment-resistant somatoform disorder as an add-on strategy. However, controlled trials are needed to investigate the effectiveness of gabapentin in the management of this condition.
Abstract: Alcohol dependence represents a severe pathological disorder associated with a significant rate of morbidity and mortality. To date, limited pharmacological agents exist to treat this disorder, and there is a growing interest for new therapies. In this context, pregabalin represents a promising strategy. Pregabalin, like gabapentin, selectively binds to the α(2)δsubunit of voltage-gated calcium channels, inhibiting release of excessive levels of excitatory neurotransmitters. The main focus of this review is the clinical use of pregabalin in alcoholic patients, but the authors also reported some data about chemistry, pharmacology, and pharmacokinetics of this drug.
Abstract: Despite a wide range of available antidepressants, the effect of the treatment is often suboptimal and there is a need for more effective and better tolerated drugs. Unlike other antidepressants, agomelatine represents a new approach to depression with an innovative mechanism of action. It is an agonist of melatoninergic receptors MT1 and MT2 and a selective antagonist of 5-HT2c receptors. In this open-label 8-week study we aimed to investigate the efficacy of agomelatine on depressive symptoms in patients with major depression. Secondary endpoints were the effect of agomelatine on anhedonia. Thirty major depressive patients received a flexible dose (25-50 mg; per os, daily) of agomelatine. Depressive (Hamilton Depression Scale) and anxious (Hamilton Anxiety Scale) symptoms, anhedonia (Snaith Hamilton Rating Scale), and sleep quality (Leeds Sleep Evaluation Questionnaire) were assessed. Twenty-four patients (80%) completed 8 weeks of treatment. Significant improvements were seen at all visits on the HAM-D (p<.05), HAM-A(p<.01), SHAPS (p<.05), LSEQ (p<.05). Nine subjects (30%) were responders and 5 (17%) remitters at week 1; 18 (60%) were remitters by the end of the trial. There was no serious adverse event. No aminotrasferase elevations were noted. In line with previous studies, in which agomelatine was associated with early clinical improvement, this study also provides evidence of an early response and the findings of improvements in depression scores. Moreover, this is the first study where agomelatine was effective in the treatment of anhedonia. Additional trials are needed to delineate the place of agomelatine in the contemporary pharmacotherapy for depressive disorders.
Abstract: The aim of this trial was to compare lorazepam with non-benzodiazepine medications such as pregabalin and tiapride in the treatment of alcohol withdrawal syndrome (AWS). These drugs were chosen for their inhibitorial effects on the hypersecretion of neurotransmitters usually observed in AWS. Craving reduction and improvement of psychiatric symptoms were the secondary end-points.
