Antihistamine drugs are extensively used to treat allergic rhinitis and other allergies. They provide relief from nasal congestion, sneezing, or hives caused by pollen and dust mites with few side effects. Various drugs with different brands and variations in prices are available in the Indian market. This study was done to fiend out the percentage variation of cost among different brands of antihistamine drugs available in the Indian market. The cost of various second-generation antihistamine drugs available in the Indian market were referred from CIMS (current index of medical specialties) (March 2022) and Indian Drug Today (Oct. 2021 to Jan. 2022). The highest and lowest price for ten (10) tablets/capsules of each second-generation antihistamine was analyzed. The percentage cost variation and cost ratio were calculated for each drug. A total of eleven oral Second Generation Antihistamines available in the Indian market and 566 oral tablets or capsules manufactured by different companies were identified for all the Second Generation Antihistamines. Huge variation was found in the cost of different branded preparations for the same drug (40.14% for cetirizine; INR 2.06 to INR 84.76). The most expensive cetirizine was 11.39 times costlier than the least expensive cetirizine. The least-cost variation and cost ratio saw with Bepotastine (10%) and (1.1) resp. This study shows tremendous variation in the prices of antihistamine drugs, especially among second-generation antihistamine drugs available in India.

Changes in Sewage Sludge Chemical Signatures During a COVID-19 Community Lockdown, Part 1: Traffic, Drugs, Mental Health, and Disinfectants was written by Nason, Sara L.;Lin, Elizabeth;Eitzer, Brian;Koelmel, Jeremy;Peccia, Jordan. And the article was included in Environmental Toxicology and Chemistry in 2022.Product Details of 83799-24-0 The following contents are mentioned in the article:

The early months of the COVID-19 pandemic and the associated shutdowns disrupted many aspects of daily life and thus caused changes in the use and disposal of many types of chems. While records of sales, prescriptions, drug overdoses, and so forth provide data about specific chem. uses during this time, wastewater and sewage sludge anal. can provide a more comprehensive overview of chem. changes within a region. We analyzed primary sludge from a wastewater-treatment plant in Connecticut, USA, collected March 19 to June 30, 2020. This time period encompassed the 1st wave of the pandemic, the initial statewide stay at home order, and the 1st phase of reopening. We used liquid chromatog.-high-resolution mass spectrometry and targeted and suspect screening strategies to identify 78 chems. of interest, which included pharmaceuticals, illicit drugs, disinfectants, UV filters, and others. We analyzed trends over time for the identified chems. using linear trend analyses and multivariate comparisons. We found trends related directly to the pandemic (e.g., hydroxychloroquine, a drug publicized for its potential to treat COVID-19, had elevated concentrations in the week following the implementation of the US Emergency Use Authorization), as well as evidence for seasonal changes in chem. use (e.g., increases for 3 UV-filter compounds). Though wastewater surveillance during the pandemic has largely focused on measuring severe acute respiratory syndrome-coronavirus-2 RNA concentrations, chem. anal. can also show trends that are important for revealing the public and environmental health effects of the pandemic. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0Product Details of 83799-24-0).

Mast cell-related symptoms might be influenced by mental health status in mastocytosis. In this study, we aimed to investigate the influence of mental health problems developed during the COVID-19 pandemic on the course of mastocytosis. Mental health status in 60 adult patients with mastocytosis was prospectively evaluated with the total Depression-Anxiety-Stress Scale (tDASS-21) and Fear of COVID-19 Scale (FCV-19S) in the lockdown period (LP) and the return to normal period (RTNP) during the pandemic. The disease course was assessed from emergency and outpatient medical reports, including Scoring Mastocytosis (SCORMA) index and serum baseline tryptase levels, by telephone interviews and clin. visits. The mean FCV-19S and median tDASS-21 scores were significantly higher in LP than RTNP (p < 0.001) and there was a pos. correlation between FCV-19S and tDASS-21 in LP (r = 0.820, p < 0.001) and in RTNP (r = 0.572 p= <0.001). Disease-related symptoms including skin lesions, flushing and anaphylaxis attacks increased in 22 patients in LP, and in this group, mean FCV-19S and median tDASS-21 were higher than those without symptom exacerbation (p < 0.001). During the study period, four (6.7%) patients who experienced COVID-19 recovered without any requirement for hospitalization and had not experienced symptom exacerbation. Fear of COVID-19 can be a reason for mental health changes, including depression, anxiety and stress which may further increase mast cell-related symptoms. Therefore, psychol. support is important to control the severity of mast cell-related symptoms in mastocytosis during a pandemic. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0HPLC of Formula: 83799-24-0).

9-Fluorenylmethoxycarbonyl (Fmoc) amino acid chlorides are useful reagents in the solid-phase synthesis of hexapeptides containing up to four sequential secondary amino acids. The oxytocin antagonist cyclo(D-Phe-Ile-D-Pip-Pip-D-MePhe-Pro) (I; Pip = pipecolic acid) was prepared in 70% overall yield starting from Boc-L-Pro-O-(PAM)-resin (Boc = tert-butoxycarbonyl). In the synthesis of I, the high reactivity of Fmoc-L-pipecolic acid chloride used in the di- to tripeptide step averted diketopiperazine formation seen with active ester couplings. The use of Fmoc-amino acid chlorides in the subsequent couplings provided a rapid method for assembly of the linear hexapeptide. The two potent cyclic hexapeptide oxytocin antagonists L-366,682 and L-366,948 were prepared in 45-48% overall yield on a 20 mmol scale using the methodol. developed for the synthesis of I. A particularly difficult coupling was encountered that involved acylation of a sterically hindered N^δ-Cbz-piperazic acid (Cbz = benzyloxycarbonyl) N-terminus with Fmoc-L-isoleucine. Excess Fmoc-L-isoleucine acid chloride in the presence of tertiary amine base gave only 30% conversion. The efficiency was improved to 76% by utilizing the acid chloride with AgCN in toluene. Further investigation revealed that this combination of reagents produces an activated form of the isoleucine 2-alkoxy-5(4H)-oxazolone derivative This study involved multiple reactions and reactants, such as (S)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)piperidine-2-carboxylic acid (cas: 86069-86-5Synthetic Route of C21H21NO4).

And the article was included in Frontiers in Pharmacology in 2022.Quality Control of 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid The following contents are mentioned in the article:

Depression is one of the main diseases that lead to disability and loss of ability to work. As a traditional Chinese medicine, Zhi-zi-chi decoction is utilized to regulate and improve depression. However, the research on the antidepressant mechanism and efficacy material basis of Zhi-zi-chi decoction has not been reported yet. Our previous research has found that Zhi-Zi-chi decoction can reduce glutamate-induced oxidative stress damage to PC 12 cells, which can exert a neuroprotective effect, and the antidepressant effect of Zhi-Zi-chi decoction was verified in CUMS rat models. In this study, the animal model of depression was established by chronic unpredictable mild stimulation combined with feeding alone. The brain metabolic profile of depressed rats was analyzed by the method of metabolomics based on ultra-performance liquid chromatog.-quadrupole/time-of-flight mass. 26 differential metabolites and six metabolic pathways related to the antidepressant of Zhi-zi-chi decoction were screened and analyzed. The targeted metabolism of the glutathione metabolic pathway was analyzed. At the same time, the levels of reactive oxygen species, superoxide dismutase, glutathione reductase, glutathione peroxidase in the brain of depressed rats were measured. Combined with our previous study, the antioxidant effect of the glutathione pathway in the antidepressant effect of Zhi-zi-chi decoction was verified from the cellular and animal levels resp. These results indicated that Zhi-zi-chi decoction exerted a potential antidepressive effect associated with reversing the imbalance of glutathione and oxidative stress in the brain of depressed rats.

Ondansetron use in nausea and vomiting during pregnancy: A descriptive analysis of prescription patterns and patient characteristics in UK general practice was written by Slattery, Jim;Quinten, Chantal;Candore, Gianmario;Pinheiro, Luis;Flynn, Robert;Kurz, Xavier;Nordeng, Hedvig. And the article was included in British Journal of Clinical Pharmacology in 2022.Name: 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid The following contents are mentioned in the article:

The objective of this study was to describe ondansetron drug utilization patterns during pregnancy to treat nausea and vomiting in pregnancy (NVP). Moreover, we aimed to describe the maternal factors associated with NVP and antiemetic use. The data consist of pregnancies with a live birth(s) within an IMRD-UK registered GP practice. Descriptive statistics were used to investigate patterns of ondansetron use in pregnancy and to describe maternal characteristics associated with NVP and antiemetic drug utilization. We differentiate first- from second-line use during pregnancy using antiemetic prescription pathways. The dataset included 733 633 recorded complete pregnancies from 2005 to 2019. NVP diagnosis and ondansetron prescription prevalence increased from 2.7% and 0.1% in 2005 to 4.8% and 2.5% in 2019 resp. Over the period 2015-2019, the most common oral daily dosages were 4 mg/d (8.5%), 8 mg/d (37.1%), 12 mg/d (37.5%) and between 16 and 24 mg/d (16.9%). Prescription of ondansetron was initiated during the first trimester of pregnancy in 40% of the cases and was moderately used as a first-line therapy (2.8%), but preferred choice of second-line therapy. Women with mental health disorders, asthma and/or prescribed folic acid were more likely to experience NVP and use antiemetics in pregnancy than their counterparts. This study confirms that ondansetron is increasingly used off-label to treat NVP during pregnancy, also in the first trimester and before other prescription antiemetics have been prescribed. Several maternal comorbidities and folic acid use were more common among women experiencing NVP and using antiemetics, including ondansetron.

Prediction of the removal efficiency of emerging organic contaminants based on design and operational parameters of constructed wetlands was written by Ilyas, Huma;Masih, Ilyas;van Hullebusch, Eric D.. And the article was included in Journal of Environmental Chemical Engineering in 2021.Formula: C32H39NO4 The following contents are mentioned in the article:

This study investigates the prediction of removal efficiency of pharmaceuticals (PhCs), personal care products (PCPs), and steroidal hormones (SHs) based on design and operational parameters (depth, area, hydraulic loading rate-HLR, organic loading rate-OLR, and hydraulic retention time-HRT) of constructed wetlands (CWs). A comprehensive statistical anal. was performed by applying principle component anal., correlation and multiple linear regression analyses. The data used in this anal. was compiled from peer reviewed publications. The CWs design and operational parameters are good predictors of the removal efficiency of these emerging organic contaminants. Operational parameters (HLR, OLR, and HRT) are the most significant predicators and combination with design parameters (depth and area) often improved reliability of the predictions. The best predictive models for PhCs and PCPs were composed of depth, OLR, and HRT (root mean square errors-RMSEs: training set: 7-14%; test set: 22-27%). A combination of area, HLR, and OLR formed a credible model for predicting the removal efficiency of SHs (RMSEs: training set: 6%; test set: 11%). Similarly, generic models by combining data of PhCs and PCPs, PhCs and SHs, PCPs and SHs, and PhCs, PCPs, and SHs showed acceptable performance. The best performing combined model for the prediction of PhCs, PCPs, and SHs was based on area, HLR, OLR, and HRT (RMSEs: training set: 13%; test set: 22%). The information obtained by the use of these models may guide researchers, practitioners, policy makers, and citizens in enhancing knowledge and understanding for the design and operation of CWs in the field conditions.

Adverse drug event risk assessment by the virtual addition of COVID-19 repurposed drugs to Medicare and commercially insured patients’ drug regimens: A drug safety simulation study was written by Smith, Matt K.;Bikmetov, Ravil;Al Rihani, Sweilem B.;Deodhar, Malavika;Hafermann, Matthew;Dow, Pamela;Turgeon, Jacques;Michaud, Veronique. And the article was included in Clinical and Translational Science in 2021.Reference of 83799-24-0 The following contents are mentioned in the article:

Drug safety is generally established from clin. trials, by pharmacovigilance programs and during observational phase IV safety studies according to drug intended or approved indications. The objective of this study was to estimate the risk of potential adverse drug events (ADEs) associated with drugs repurposed for coronavirus disease 2019 (COVID-19) treatment in a large-scale population. Drug claims were used to calculate a baseline medication risk score (MRS) indicative of ADE risk level. Fictitious claims of repurposed drugs were added, one at a time, to patients drug regimens to calculate a new MRS and compute a level of risk. Drug claims data from enrollees with Regence health insurance were used and sub-payer analyses were performed with Medicare and com. insured groups. Simulated interventions were conducted with hydroxychloroquine and chloroquine, alone or combined with azithromycin, and lopinavir/ritonavir, along with terfenadine and fexofenadine as pos. and neg. controls for drug-induced Long QT Syndrome (LQTS). There were 527,471 subjects (56.6women; mean [SD] age, 47 years [21]) were studied. The simulated addition of each repurposed drug caused an increased risk of ADEs (median MRS increased by two-to-seven points, p < 0.001). The increase in ADE risk was mainly driven by an increase in CYP450 drug interaction risk score and by drug-induced LQTS risk score. The Medicare group presented a greater risk overall compared to the com. group. All repurposed drugs were associated with an increased risk of ADEs. Our simulation strategy could be used as a blueprint to preemptively assess safety associated with future repurposed or new drugs.

Efficacy and safety of up-dosing antihistamines in chronic spontaneous urticaria: a systematic review of the literature was written by Iriarte, Sotes P.;Armisen, M.;Usero-Barcena, T.;Rodriguez, Fernandez A.;Otero, Rivas MM;Gonzalez, Mt;Meijide, Calderon A.;Veleiro, B.. And the article was included in Journal of Investigational Allergology and Clinical Immunology in 2021.Synthetic Route of C32H39NO4 The following contents are mentioned in the article:

According to current guidelines, oral antihistamines are the first-line treatment for chronic spontaneous urticaria (CSU). Up-dosing antihistamines to 4-fold the licensed dose is recommended if control is not achieved. Such indications are based mainly on expert opinion. To critically review and analyze clin. evidence on the efficacy and safety of higher-than-licensed dosage of second-generation oral antihistamines in the treatment of CSU. A systematic literature review was performed following a sensitive search strategy. All articles published in PubMed, EMBASE, and the Cochrane Library between 1961 and Oct. 2018 were examined Publications with CSU patients prescribed secondgeneration antihistamines in monotherapy compared with placebo, licensed dosages, and/or higher dosages were included. Articles were evaluated by peer reviewers. Quality was evaluated using the Jadad and Oxford scores. We identified 337 articles, of which 14 were included in the final evaluation (fexofenadine, 6; cetirizine, 2; levocetirizine and desloratadine, 1; levocetirizine, 1; rupatadine, 2; ebastine, 1; and bilastine, 1). Only 5 studies were placebo-controlled. The number of patients included ranged from 20 to 439. The observation lapse was ≤16 wk. High fexofenadine doses produced a significant dosedependent response and controlled urticaria in most patients. Cetirizine, levocetirizine, rupatadine, and bilastine were more effective in up-dosing. The most frequent adverse events were headache and drowsiness. The low quality and heterogeneity of the articles reviewed made it impossible to reach robust conclusions and reveal the need for large-scale randomized clin. trials.
