Peripheral blood (PB) is considered to be the golden standard for measuring postmortem drug concentrations. In several cases, PB is however not available, but information regarding drug findings might still be crucial in order to determine the cause of death. Antidepressants are frequently detected in postmortem samples from forensic toxicology cases, but the literature investigating concentrations in other matrices than peripheral and heart blood is limited.We here describe a study for comparison of concentrations for a large number of different drugs in six different matrices...

BACKGROUND: Insomnia disorder is a subjective condition of unsatisfactory sleep (e.g. sleep onset, maintenance, early waking, impairment of daytime functioning). Insomnia disorder impairs quality of life and is associated with an increased risk of physical and mental health problems including anxiety, depression, drug and alcohol abuse, and increased health service use. hypnotic medications (e.g. benzodiazepines and 'Z' drugs) are licensed for sleep promotion, but can induce tolerance and dependence, although many people remain on long-term treatment...

SALDI-MS analysis of pharmaceutical drug molecules (amitriptyline, imipramine and promazine) using carbon-based substrates, namely, activated charcoal (AC), carbon nanotubes (CNTs), carbon black (CB), graphene (rGO), graphene oxide (GO) and graphite, was explored and compared with the conventional organic matrix of MALDI. CB exhibited superior performance with respect to the other substrates in terms of detection sensitivity. Despite the effectiveness of CB to detect all drug molecules, it demonstrated a number of background signals, which may be an issue for the analysis of other molecules in the future...

Amitriptyline is a commonly used tricyclic antidepressant (TCA) inhibiting serotonin and norepinephrine reuptake. The exact CNS action of TCAs remains poorly understood, necessitating new screening approaches and novel model organisms. Zebrafish (Danio rerio) are rapidly emerging as a promising tool for pharmacological research of antidepressants, including amitriptyline. Here, we examine the effects of chronic 2-week exposure to 10 and 50 μg/L amitriptyline on zebrafish behavior and monoamine neurotransmitters...

A large number of antidepressant drugs are available across the world. All have been compared against placebo, and many have been compared with some but not all other antidepressants. There is therefore little information about a hierarchy of the efficacy and acceptability of these drugs. About 9 years ago, a network meta-analysis attempted to rank the efficacy and acceptability of 12 newer antidepressant drugs in adults with major depressive disorder. Very recently, this network meta-analysis was updated to include 21 antidepressant drugs, most of which were introduced during the 1980s and afterward...

The activity of tricyclic antidepressants (TCAs) at α7 and α9α10 nicotinic acetylcholine receptors (AChRs) as well as at hippocampal α7-containing (i.e., α7*) AChRs is determined by using Ca2+ influx and electrophysiological recordings. To determine the inhibitory mechanisms, additional functional tests and molecular docking experiments are performed. The results established that TCAs (a) inhibit Ca2+ influx in GH3-α7 cells with the following potency (IC50 in µM) rank: amitriptyline (2.7 ± 0.3) > doxepin (5...

BACKGROUND: Antidepressant withdrawal manic states are intriguing and under-recognized phenomena. The associated patho-physiological pathways are ill defined and the inclusion of the phenomena in the bipolar spectrum disorders is questionable. This study aims to update a review on antidepressant discontinuation manic states published in 2008 and to look for hints alluding to bipolar disorder in the affected published cases and in the literature. It also reviews the different hypotheses proposed to explain discontinuation mania...

A comprehensive study of the removal of selected biologically active compounds (pharmaceuticals and pesticides) from different water types was conducted using bare TiO2 nanoparticles and TiO2 /polyaniline (TP-50, TP-100, and TP-150) nanocomposite powders. In order to investigate how molecular structure of the substrate influences the rate of its removal, we compared degradation efficiency of the initial substrates and degree of mineralization for the active components of pharmaceuticals (propranolol, and amitriptyline) and pesticides (sulcotrione, and clomazone) in double distilled (DDW) and environmental waters...

BACKGROUND: In 2012, the Food and Drug Administration issued Drug Safety Communications on several drugs associated with QT prolongation and fatal ventricular arrhythmias. Among these was citalopram, a selective serotonin reuptake inhibitor (SSRI) approved for depression and commonly used for posttraumatic stress disorder (PTSD). Evaluation of the risk for QT prolongation among other psychotropic drugs for individuals with PTSD remains limited. OBJECTIVE: Explore psychotropic drugs associated with QT prolongation among veterans with PTSD...

TCAs are known to be toxicants and endocrine disrupting agents. Generally, after being used, TCAs are passed through wastewater treatment plants (WWTPs) to be treated. However, still trace amounts (ng/L to μg/L) of TCAs have been founded even in the treated water. Therefore, the aim of this study is to elucidate the environmental behaviors of TCAs in the sewage water from WWTPs (Jeonju, Korea). For the experiments, seven TCAs (amitriptyline, imipramine, clomipramine, desipramine, protriptyline, nortriptyline, and doxepin) were selected...

Amitriptyline (AMIT) is a compound widely prescribed for psychiatric and non- psychiatric conditions including depression, migraine, chronic pain, and anorexia. However, AMIT has been associated with risks of cardiac arrhythmia and sudden death since it can induce prolongation of the QT interval on the surface electrocardiogram and torsade de pointes ventricular arrhythmia. These complications have been attributed to the inhibition of the rapid delayed rectifier potassium current (IKr ). The slow delayed rectifier potassium current (IKs ) is the main repolarizing cardiac current when IKr is compromised and it has an important role in cardiac repolarization at fast heart rates induced by an elevated sympathetic tone...

During sepsis, the early innate response and inflammatory cytokine cascade are associated with activation of the coagulation cascade. Acute hypercoagulability can contribute to lethal sequela of vascular thrombosis, tissue ischemia, and organ failure. We investigated if amitriptyline (AMIT), an antidepressant drug with a number of anti-inflammatory effects, could ameliorate sepsis in a murine model of sepsis - cecal ligation and puncture (CLP). We hypothesized that AMIT treatment would reduce inflammation and mitigate sepsis-induced coagulopathy...
