BACKGROUND: Neuropathic pain, which is caused by a lesion or disease affecting the somatosensory system, may be central or peripheral in origin. Neuropathic pain often includes symptoms such as burning or shooting sensations, abnormal sensitivity to normally painless stimuli, or an increased sensitivity to normally painful stimuli. Neuropathic pain is a common symptom in many diseases of the nervous system. Opioid drugs, including morphine, are commonly used to treat neuropathic pain...

This review presents the most recent data of worldwide research on anxiety and depressive disorders in patients with Parkinson's disease. Their characteristics and epidemiology, pathogenetic and clinical features, methods of diagnosis and treatment are presented. Depression occurs in 40-50% of patients with PD, anxiety in 17-43% of patients. Pramipexole, a dopamine agonist, is only one drug recommended for depression treatment. Nortriptyline and desipramine, belonging to the group of tricyclic antidepressants (TCAs), are considered to be possibly effective...

OBJECTIVES: To investigate smoking treatment effectiveness and retention in a population with and without mental disorders (MD). Participants received cognitive-behavioral therapy (CBT) plus nicotine patch alone or in combination with other medications (i.e., gum, bupropion, or nortriptyline) for smoking cessation treatment in a Brazilian Psychosocial Care Center unit (CAPS), taking into account sociodemographics and smoking profile covariates. METHODS: Comparison of treatment success (7-day point prevalence abstinence at the end of the treatment) and retention (presence of the individual in all of the 4 medical consultations and 6 group sessions) in two subsamples of patients with MD (n = 267) and without MD (n = 397) who were included in a 6-week treatment provided by a CAPS from 2007 to 2013...

The purpose of this study was to evaluate the skin permeation of tricyclic antidepressants (TCAs) with propamine moiety to select candidates for the development of topical analgesics to treat cutaneous pain. We sought to establish the structure-permeation relationship (SPR) of topical TCAs. The lipophilicity, melting point, and aqueous solubility were determined to develop the physicochemical characterization. The TCA permeation into pig and nude mouse skins was estimated using Franz diffusion cell. TCAs and lidocaine were comparatively examined for cutaneous analgesia by pinprick assay...

We performed a double-blinded, genotype-based stratification study to explore the pharmacokinetics and pharmacodynamics of amitriptyline according to CYP2C19 and CYP2D6 genotype in Korean subjects. Twenty-four healthy adults were grouped by genotype of CYP2C19 and CYP2D6. After a single dose of 25 mg of amitriptyline, blood samples were collected and anticholinergic effects were measured. The extent of N-demethylation of amitriptyline significantly decreased in subjects carrying two nonfunctional alleles of CYP2C19...

We demonstrated the effect of nortriptyline, a tricyclic antidepressant drug and serotonin reuptake inhibitor, on voltage-dependent K(+) (Kv) channels in freshly isolated rabbit coronary arterial smooth muscle cells using a whole-cell patch clamp technique. Nortriptyline inhibited Kv currents in a concentration-dependent manner, with an apparent IC50 value of 2.86±0.52 µM and a Hill coefficient of 0.77±0.1. Although application of nortriptyline did not change the activation curve, nortriptyline shifted the inactivation current toward a more negative potential...

Current pharmacological treatments for major depressive disorder (MDD) are ineffective in a significant proportion of patients, and the identification of new antidepressant compounds has been difficult. 'Connectivity mapping' is a method that can be used to identify drugs that elicit similar downstream effects on mRNA levels when compared to current treatments, and thus may point towards possible repositioning opportunities. We investigated genome-wide transcriptomic changes to human hippocampal progenitor cells treated with therapeutically relevant concentrations of a tricyclic antidepressant (nortriptyline) and a selective serotonin reuptake inhibitor (escitalopram)...

Dear Editor, Pityriasis rosea is a common, acute, and self-limiting dermatosis, which is associated with the endogenous systemic reactivation of human herpesvirus (HHV)-6 and/or HHV-7 (1). It predominantly affects individuals of both sexes in their second or third decade of life and is clinically characterized by the occurrence of an initial erythematosquamous plaque followed by the appearance of disseminated similar but smaller lesions one or two weeks later. Several patients develop systemic symptoms such as nausea, anorexia, malaise, headache, fever, arthralgia, and lymphadenopathy that may precede or accompany the eruption; the latter follows the cleavage lines of the trunk creating the configuration of a Christmas tree and spontaneously resolves within 4 to 8 weeks...

Over the past years, the use of antidepressants and neuroleptics has steadily increased. Although incredibly useful to treat disorders like depression, schizophrenia, epilepsy, or mental retardation, these drugs display many side effects. Toxicogenomic studies aim to limit this problem by trying to identify cellular targets and off-targets of medical compounds. The baker yeast Saccharomyces cerevisiae has been shown to be a key player in this approach, as it represents an incredible toolbox for the dissection of complex biological processes...

CYP2D6 and CYP2C19 polymorphisms affect the exposure, efficacy and safety of tricyclic antidepressants (TCAs), with some drugs being affected by CYP2D6 only (e.g., nortriptyline and desipramine) and others by both polymorphic enzymes (e.g., amitriptyline, clomipramine, doxepin, imipramine, and trimipramine). Evidence is presented for CYP2D6 and CYP2C19 genotype-directed dosing of TCAs. This document is an update to the 2012 Clinical Pharmacogenetics Implementation Consortium (CPIC) guideline for CYP2D6 and CYP2C19 Genotypes and Dosing of Tricyclic Antidepressants...

The use of a new class of hybrid materials, called restricted access molecularly imprinted polymers (RAMIPs) seems to present a good strategy for the sample preparation of complex matrices, since these materials combine good protein elimination capacity with high degree selectivity. Mass spectrometers (MS) have been successfully used for polar drug identification and quantification. In order to combine the advantages of both RAMIPs and mass spectrometry, we proposed a study that joins these properties in a single system, where we could analyse tricyclic antidepressants from human plasma, without offline extraction or chromatographic separation...

Preclinical and clinical evidence suggests that glial cell line-derived neurotrophic factor (GDNF) is important in the therapeutic effect of antidepressants. A previous study demonstrated that the tricyclic antidepressant amitriptyline induces Gαi/o activation, which leads to GDNF expression in astrocytes. However, the specific target expressed in astrocytes that mediates antidepressant-evoked Gαi/o activation has yet to be identified. Thus, the current study explored the possibility that antidepressant-induced Gαi/o activation depends on lysophosphatidic acid receptor 1 (LPAR1), a Gαi/o-coupled receptor...

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...

OBJECTIVE: The anticholinergic activity (AA) assay is a common method to determine a patient's anticholinergic load. Several limitations, however, are expected when applying the AA assay to patients or using drug scales to estimate anticholinergic burden based on AA levels. This study aims to demonstrate common pitfalls in an experimental setting and outline their clinical consequences. METHODS: The AA was analyzed for five drugs with reported interaction with muscarinic receptors...
