Delving into the Latest Updates on Hydroxyzine Hydrochloride with Synapse

Overview

Basic Info

SummaryHydroxyzine is a first-generation antihistamine that is commonly used for the treatment of various allergic conditions such as hives and itching. It works by blocking the action of histamine, a chemical released in response to an allergic reaction. Histamine causes symptoms such as itching, swelling, and rash. Hydroxyzine is available in oral and injectable formulations. It is generally well tolerated by patients. However, side effects can include drowsiness, dizziness and dry mouth. It is important to note that there is ongoing research regarding the potential use of hydroxyzine to treat anxiety disorders, as it has shown some anxiolytic activity in preclinical studies.

The aim of this study is to evaluate the efficacy of hydroxyzine compared to treatment as usual (TAU) for patients with panic disorder. By conducting a pilot study, we hope to provide initial data on the feasibility and potential impact of hydroxyzine for this population. This will inform the design and power calculations of a larger, more comprehensive study in the future.
Objectives:
To assess the feasibility of conducting a randomized controlled trial (RCT) of hydroxyzine for panic disorder.
To evaluate the effectiveness of hydroxyzine compared to TAU in reducing panic symptoms in patients with panic disorder.
To explore the potential side effects and tolerability of hydroxyzine in this population.
Methods:
This will be a single-center, open-label, randomized pilot study. A total of 30 patients with a primary diagnosis of panic disorder will be recruited from a psychiatric outpatient clinic. Participants will be randomly assigned to receive either hydroxyzine or TAU for 8 weeks. The primary outcome measure will be the change in panic symptoms as assessed by the Panic Disorder Severity Scale (PDSS). Secondary outcome measures will include the Hamilton Anxiety Rating Scale (HAM-A) and the Clinical Global Impression-Severity (CGI-S) scale. Participants will be assessed at baseline, 4 weeks, and 8 weeks. Adverse events will be monitored throughout the study.
Expected Results:
This pilot study is expected to provide preliminary data on the feasibility and potential efficacy of hydroxyzine for panic disorder. The results will inform the design of a larger RCT to further evaluate the efficacy of hydroxyzine for this population.
Significance:
There is a need for effective and well-tolerated treatments for panic disorder. If found to be effective, hydroxyzine could provide a new option for patients with this condition, potentially improving their quality of life and functioning. The results of this pilot study will inform the design of future studies and contribute to the development of evidence-based treatments for panic disorder.

Using Zebrafish G Protein-Coupled Receptors to Obtain a Better Appreciation of the Impact of Pharmaceuticals in Wastewater to Fish

Article

Author: Johnson, Andrew C. ; Ihara, Mariko O. ; Zhang, Han ; Chen, Jingwen ; Cao, Mingyuan ; Jürgens, Monika D. ; Tanaka, Hiroaki ; Ihara, Masaru

Pharmaceutical discharge to the environment is of concern due to its potential adverse effects on aquatic species. It is estimated that around 40% of pharmaceuticals target G protein-coupled receptors (GPCRs). The in vitro transforming growth factor-α (TGFα) shedding assay was applied to measure the antagonistic activities of pharmaceuticals against human GPCRs. However, their ability to stimulate fish GPCRs remains unclear. Here, antagonistic activities of 30 pharmaceuticals against zebrafish dopamine (zD2a and zD2c), adrenergic family member (zβ1), and histamine (zH1 and zH3) receptors were measured by the TGFα shedding assay. The study found an interspecies difference in binding affinities between human and zebrafish: pharmaceuticals more strongly inhibited the zD2c and zH1 receptors than human D2 (hD2) and hH1 receptors, while zD2a and zβ1 receptors were less inhibited than hD2 and hβ1 receptors. The potential molecular explanations for the observed interspecies differences in binding affinity for hydroxyzine and bisoprolol were investigated using molecular docking. Pharmaceutical potency against zebrafish GPCRs and predicted effluent concentrations were used to predict equivalent quantities (EQs), and these EQs were used to prioritize pharmaceuticals of concern in wastewater in England and Japan. This study highlights the use of the TGFα shedding assay adopting zebrafish GPCRs to better understand the ecological effects of pharmaceuticals on fish.

Psychotherapeutic and pharmacological agents for post-traumatic stress disorder with sleep disorder: network meta-analysis

Review

Author: Zhang, Chao ; Zhao, Yi-Fan ; Liu, Run-Ben ; Liu, Jia-Ling ; Huang, Cheng-Yang ; Zhang, Zhi-Xin ; Li, Xiao-Zheng ; Luo, Jie ; Yue, Li

OBJECTIVEThe current guidelines and canonical norms of diagnosis or treatment for Post-traumatic stress disorder (PTSD) with sleep disorder are still conflicting and have not yet reached a consensus. This study aimed to unravel the most effective countermeasures between two categories (psychotherapy and pharmacotherapy) put forward by the National Institute for Health and Clinical Excellence (NICE) and World Federation of Societies of Biological Psychiatry (WFSBP) respectively to treat PTSD individuals co-exist with sleep disorders.METHODSFour databases, including PubMed, EMBASE, Cochrane Library, and APA PsyNet, were searched from inception to February 02, 2023.RESULTSTwenty articles with 24 Randomized controlled trials (RCTs) and a total number of 1,647 participants were included. As demonstrated in the network meta-analysis comparison results, CBT-I (standardized mean differences (SMD) = -1.51,95% confidence interval (CI):-2.55 to -0.47), CBT-I plus IRT (SMD = -1.71, 95%CI:-3.39, -0.03), prazosin (SMD = -0.87,95%CI:-1.59 to -0.16) and hydroxyzine (SMD = -1.06, 95%CI: -1.94 to -0.19) significantly reduced PTSD symptoms compared with placebo. In contrast to placebo, CBT-I (SMD = -5.61,95%CI:-8.82 to -2.40) significantly improved sleep quality. For nightmare severity, IRT (SMD =-0.65, 95%CI:-1.00 to -0.31), prazosin (SMD = -1.20,95%CI:-1.72 to -0.67) and hydroxyzine (SMD = -0.98,95%CI:-1.58 to -0.37) significantly reduced nightmare severity in comparison with placebo.CONCLUSIONSThis study suggested that under most circumstances, psychotherapy namely CBT-I had a favorable profile, but pharmacotherapy with prazosin was effective in managing nightmare severity. The sole avail of CBT-I was recommended to improving sleep quality while CBT-I and CBT-I plus IRT showed excellent management of PTSD symptom severity. Exposure to CBT-I isrecommended for depression. The relevant clinical guidelines for the management of individuals with PTSD and sleep disorders may regard this as a reference.PROSPEROCRD42023415240.

Effects of dopamine receptor antagonists and radiation on mouse neural stem/progenitor cells

Article

Author: Bhat, Kruttika ; He, Ling ; Ioannidis, Angeliki ; Pajonk, Frank

BACKGROUNDDopamine receptor antagonists have recently been identified as potential anti-cancer agents in combination with radiation, and a first drug of this class is in clinical trials against pediatric glioma. Radiotherapy causes cognitive impairment primarily by eliminating neural stem/progenitor cells and subsequent loss of neurogenesis, along with inducing inflammation, vascular damage, and synaptic alterations. Here, we tested the combined effects of dopamine receptor antagonists and radiation on neural stem/progenitor cells.METHODSUsing transgenic mice that report the presence of neural stem/progenitor cells through Nestin promoter-driven expression of EGFP, the effects of dopamine receptor antagonists alone or in combination with radiation on neural stem/progenitor cells were assessed in sphere-formation assays, extreme limiting dilution assays, flow cytometry and real-time PCR in vitro and in vivo in both sexes.RESULTSWe report that hydroxyzine and trifluoperazine exhibited sex-dependent effects on murine newborn neural stem/progenitor cells in vitro. In contrast, amisulpride, nemonapride, and quetiapine, when combined with radiation, significantly increased the number of neural stem/progenitor cells in both sexes. In vivo, trifluoperazine showed sex-dependent effects on adult neural stem/progenitor cells, while amisulpride demonstrated significant effects in both sexes. Further, amisulpride increased sphere forming capacity and stem cell frequency in both sexes when compared to controls.CONCLUSIONWe conclude that a therapeutic window for dopamine receptor antagonists in combination with radiation potentially exists, making it a novel combination therapy against glioblastoma. Normal tissue toxicity following this treatment scheme likely differs depending on age and sex and should be taken into consideration when designing clinical trials.
