REVIEW
Pratap R Chokka, Jeffrey R Hankey
Sexual dysfunction (SD) is pervasive and underreported, and its effects on quality of life are underestimated. Due in part to its bidirectional relationship with depression, SD can be difficult to diagnose; it is also a common side effect of many antidepressants, leading to treatment noncompliance. While physicians often count on patients to spontaneously report SD, treatment is optimized when the clinician instead performs a thorough assessment of sexual functioning before and during drug therapy using a standardized questionnaire such as the Arizona Sexual Experiences Scale (ASEX)...

Approximately 21% of patients with bipolar disorder (BD) also have an additional diagnosis of obsessive-compulsive disorder (OCD). This condition is associated with a more severe prognosis and complicates the treatment of BD. In our case report we provide documentary evidence of our experience with trazodone prolonged release in the treatment of depressive phase in a patient with BD II-OCD comorbidity. Rationality in the choise of treatment was based on the need to manage depressive and obsessive symptoms without facilitating hypomania switches...

Trazodone is a serotonin receptor antagonist and reuptake inhibitor used extensively as an anxiolytic in human and small animal veterinary medicine. The aims of this study were to determine the pharmacokinetics of oral trazodone in experimental horses and to evaluate the effect of oral trazodone in clinical horses. Six experimental horses were administered trazodone at 7.5 or 10 mg/kg. Plasma concentrations of trazodone and its metabolite (m-CPP) were determined via UPLC-MS/MS. Noncompartmental pharmacokinetic analysis, sedation and ataxia scores were determined...

This study aims to prove that ionic liquids (ILs) can be used as extraction solvents in a liquid-liquid microextraction, coupled to LC-MS/MS, for the quantification of a large group of antidepressants in whole blood samples. The sample preparation procedure consisted of adding 1.0mL aqueous buffer pH 3.0 and 60µL of IL (1-butyl-3-methylimidazolium hexafluorophosphate) to 1.0mL whole blood. Subsequently, a 5-min rotary mixing step was performed followed by centrifugation. The lower IL phase was collected, diluted 1:10 in methanol and 10µL was injected into the LC-MS/MS...

Luca Settimo, David Taylor
Trazodone is a drug that was introduced in the clinic almost 40 years ago. It is licensed to treat depression, but it is also commonly used off-label to treat insomnia. A recent study shows that it could be promising in preventing neurodegeneration in mice, and clinical trials to assess its possible beneficial effects on dementia and Alzheimer's disease are expected to start soon in humans. In this study, we describe the dose-dependent pharmacology of trazodone by carrying out pharmacokinetic simulations aiming to predict the brain concentrations of trazodone for different drug-dosing regimens and calculating occupancy for 28 different targets for which published trazodone-binding data are available...

In order to develop a novel strategy to alleviate the inherent hepatotoxicity of antidepressant trazodone (TZ), Cucurbit[7]uril (CB[7]) was adopted as pharmaceutical excipients and was studied for its capability to reduce the hepatotoxicity of TZ via supramolecular encapsulation. CB[7] was found to form strong 1:1 host-guest complexes with TZ and its metabolite m-chlorophenyl piperazine (mCPP), with binding constants of 1.50 (±0.13) × 106 M-1 and 6.90 (±0.49) × 105 M-1, respectively. The supramolecular complexations were examined by 1H NMR and UV-visible spectroscopic titrations, ESI-MS and ITC...

Trazodone is a clinically available anti-depressant that exhibits affinity for serotonin 1A and 2A receptors, as well as for alpha-adrenoceptors, suggesting that it may be useful to treat L-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesia and psychosis that are encountered in advanced Parkinson's disease (PD). Here, we investigated the anti-dyskinetic and anti-psychotic effects of trazodone in the parkinsonian non-human primate. 6 common marmosets were rendered parkinsonian by administration of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)...

AIM: We examined the first- and second-line pharmacological treatment for delirium to determine which drugs were chosen, how and when second-line drugs were started, and the effectiveness and tolerability of those treatments. METHODS: A retrospective medical chart review was performed for delirium inpatients referred to the Department of Psychiatry, Hiroshima Citizens Hospital, from October 2011 to September 2012. Clinical diagnoses were based on ICD-10. We compared the baseline severity of delirium, duration needed for improvement, and rescue with antipsychotics between subjects given only first-line drugs and those switched to second-line drugs...

Idiopathic normal pressure hydrocephalus (INPH) is characterized by the clinical triad of gait and cognitive dysfunction and urinary incontinence. Ventriculoperitoneal (VP) shunting is often required for treatment. Review of literature shows few case reports discussing benign magnetic resonance imaging (MRI) T2 hyperintense changes in the corpus callosum of NPH patients after shunting due to mechanical compression of the middle and posterior regions of the body against falx cerebri leading to ischemic demyelination...

Although an inhibition of action potential conduction in nerve fibers possibly contributes to at least a part of antinociception produced by analgesics and the adjuvants, it has not been fully examined yet how the conduction inhibition differs in extent among their drugs. We investigated the effects of various antidepressants used as analgesic adjuvants on compound action potentials (CAPs) recorded from the frog sciatic nerve by using the air-gap method. The results were compared with those of the other adjuvants that were reported previously...

OBJECTIVES: Recent published evidence suggests that adjunctive trazodone treatment may limit serotonin reuptake inhibitor (SRI) response in depressed adolescents in the context of a controlled trial. This study examined the effects of adjunctive trazodone on depression outcome in adolescents in a naturalistic treatment environment. METHODS: We conducted a cohort study through chart review of a clinical sample. Patients in our sample were 15 to 18 years of age treated with either a selective serotonin reuptake inhibitor or serotonin and norepinephrine reuptake inhibitor...

Based on the original literature, the author for the first time describes a history of selective serotonergic antidepressants simultaneously inhibiting the serotonin reuptake and directly interacting with serotonin receptors. A history of creation and introduction of their main representatives is presented. A history of investigation of their neurochemical activity is analyzed in details. The history of the evolution of their classifications is systemized. The data presented suggest the rationale for unifying all selective serotonergic antidepressants, simultaneously inhibiting the serotonin reuptake and directly interacting with serotonin receptors (trazodone, etoperidone, nefazodone, vilazodone, vortioxetine), in one group of 'multimodal serotonergic antidepressants'...
