Delving into the Latest Updates on Loratadine with Synapse

Overview

Basic Info

SummaryClaritin (loratadine) is a medication commonly used to treat allergies such as hay fever and hives. It belongs to the second-generation antihistamine family of medications and is taken orally. While common side effects include dry mouth, sleepiness, and headache, serious side effects such as allergic reactions, seizures, and liver problems are rare. Loratadine is generally considered safe during pregnancy, but its effects have not been well studied in this population. Children under two years of age should not take this medication. Loratadine was patented in 1980 and first became available in 1988. It is listed as an essential medication by the World Health Organization and is available as a generic. In the US, it can be purchased over the counter and was one of the most commonly prescribed medications in 2020, with over 9 million prescriptions.

Protein-Affinity Guided Nontargeted Analysis Reveals the Widespread FXR-Antagonistic Pollutants in Surface Water and Source Water Along the Yangtze River and Yellow River

Article

Metabolism-disrupting chemicals (MDCs) have attracted widespread attention due to their contributions to the prevalence of metabolic diseases worldwide. The farnesoid X receptor (FXR) is a typical lipid-sensing nuclear receptor and plays a crucial role in the development of metabolic diseases. However, few studies have examined the FXR activities of environmental samples and the corresponding MDCs. In this study, we found FXR-antagonistic activities in 93.6% of source water, surface water, and wastewater samples (n = 78) collected from the Yangtze River and Yellow River. An FXR protein-affinity guided nontargeted analysis was performed and identified 79 potential FXR-active pollutants in samples from these two rivers. Nine of these pollutants exhibited strong FXR-antagonistic activities (IC₅₀: 2.39-141.9 μM), and 6 pollutants, including triphenyl phosphate (TPHP), 4,4'-sulfonylbis[2-(2-propenyl) phenol (TGSA), tonalid (AHTN), dichlorophen, etoxazole (ETX), and loratadine, were identified to be FXR antagonists for the first time. The total concentrations of the nine FXR-antagonistic pollutants were relatively high in the middle and downstream reaches of the Yellow River and the downstream reaches of the Yangtze River, and two pollutants (TGSA and ETX) have not previously been found in aquatic environments. A risk prioritization analysis revealed that TPHP, TGSA, and AHTN are priority pollutants with the potential to affect the FXR. Appropriate management of these priority pollutants would reduce the health risks of metabolic disruptions associated with exposure to these MDCs.

Development of a method to evaluate the effects of external environments on drug stability in nails using micro‐segmental analysis

Article

Author: Kanamori, Tatsuyuki ; Okada, Yuki ; Iwata, Yuko T. ; Yamamuro, Tadashi ; Tsujikawa, Kenji ; Miyaguchi, Hajime ; Segawa, Hiroki ; Kuwayama, Kenji

Abstract:

Nails can be used as an alternative to hair for examining past drug use. However, daily hand‐and‐nail care can eliminate the internal drugs. Therefore, we developed an evaluation method to examine the effects of the external environment on drug stability in nails using micro‐segmental analysis. First, reference nails containing drugs were prepared by collecting fingernails from participants who had consumed hay‐fever medicines continuously for 4 months. Next, the entire free edge of a reference nail was cut into halves at the centerline; one side was stored as an untreated block, and the other was treated with various hand/nail care products. Both nail blocks were washed and segmented at 0.5‐mm intervals in the width direction. Each segment in the extraction solution was crushed with stainless‐steel beads, sonicated, and soaked in the solution for 24 h. The analytes in extracts were quantified by LC–MS/MS, and the drug concentrations between the treated and untreated blocks were compared. The drug concentrations decreased slightly in nails treated with manicure and gel‐nail products. The analytes in nails tended to be lower in water‐rich products such as hand soap and hand cream than in oil‐rich products such as nailcare oil and acetone‐free remover. The developed method using micro‐segmental analysis enabled the evaluation of the effects of various hand/nail care products on drug stability in a limited number of nails. This would also be useful for examining the effects of severe environments on drugs in nails collected from cases of unnatural death.

Deciphering H1 receptor antagonists and Keeping Up with Their Recent Developments

The H1 receptor, also known as the histamine H1 receptor, plays a crucial role in the human body. It is primarily found in smooth muscle cells, endothelial cells, and nerve cells. Activation of the H1 receptor by histamine leads to various physiological responses, including vasodilation, increased vascular permeability, bronchoconstriction, and stimulation of sensory nerve endings. These responses are involved in allergic reactions, inflammation, and immune responses. Antagonists of the H1 receptor, commonly known as antihistamines, are widely used to treat allergies, hay fever, and other conditions associated with excessive histamine release. Understanding the role of the H1 receptor is essential for developing effective treatments for allergic and inflammatory disorders. The analysis of the target H1 receptor reveals a competitive landscape with multiple companies actively developing drugs. GSK Plc, Sanofi, Pfizer Inc., Bayer AG, and Novartis AG are among the companies with the highest number of approved drugs or drugs in advanced stages of development. The indications with the most approved drugs include Common Cold, Rhinitis, Allergic, Urticaria, Pruritus, and Hypersensitivity. Small molecule drugs are the most rapidly progressing drug type, indicating intense competition in this area. China, the United States, and Japan are the countries with the highest number of approved drugs, with China showing significant progress in the development of drugs targeting the H1 receptor. Overall, the target H1 receptor presents opportunities for further research and development, particularly in indications with high unmet medical needs. How do they work?H1 receptor antagonists, also known as H1 blockers or antihistamines, are a class of drugs that block the action of histamine at the H1 receptor. Histamine is a chemical released by the body during an allergic reaction, causing symptoms such as itching, sneezing, runny nose, and watery eyes. H1 receptor antagonists work by binding to the H1 receptors on cells, preventing histamine from binding and exerting its effects. From a biomedical perspective, H1 receptor antagonists are commonly used to treat allergic conditions, such as hay fever (allergic rhinitis), hives (urticaria), and allergic conjunctivitis. They help alleviate symptoms by reducing the effects of histamine, thereby relieving itching, sneezing, and other allergic reactions. There are different generations of H1 receptor antagonists, each with varying degrees of sedative effects. First-generation antihistamines, such as diphenhydramine and chlorpheniramine, can cause drowsiness and are often used for their sedative properties in addition to their antihistamine effects. Second-generation antihistamines, such as cetirizine, loratadine, and fexofenadine, are less likely to cause sedation and are preferred for daytime use. In summary, H1 receptor antagonists are drugs that block the action of histamine at the H1 receptor, providing relief from allergic symptoms. They are commonly used in the treatment of various allergic conditions and come in different generations with varying sedative effects. List of H1 receptor Antagonists The currently marketed H1 receptor antagonists include: Olopatadine Hydrochloride/Mometasone Furoate Monohydrate Chlorpheniramine Maleate/Codeine Phosphate Diphenhydramine Hydrochloride/Naproxen Sodium Recombinant interferon alfa-2b/Loratadine Rupatadine Fumarate Azelastine/mometasone Ebastine/Pseudoephedrine Hydrochloride Azelastine Hydrochloride/Fluticasone Propionate Chlorpheniramine Maleate/Hydrocodone Bitartrate/Pseudoephedrine Hydrochloride Alcaftadine The content above comes from the network. if any infringement, please contact us to modify.

Bayer taps new North America marketing chief for consumer health division

“I’m excited to leverage my passion for building consumer-led, purpose-driven brands across the Consumer Health portfolio, which includes many brands that I know and love, like Claritin, Aspirin, and Midol,” Samantha Avivi said in this week's announcement. In yet another C-suite shift for Bayer’s consumer health business, the division’s North America segment has appointed a new chief marketing officer. Samantha Avivi is slated to take over the role from Jeff Jarrett, Bayer announced Tuesday. Jarrett had served as marketing chief for Bayer Consumer Health’s North America region since mid-2020—a year after he joined the pharma—and is planning to retire from the company at the end of May. In a LinkedIn post Tuesday, Jarrett called his departure “truly bittersweet,” as he cited the “incredible journey” of working at Bayer while noting that “after five years at Bayer, and nearly 55 years of life, I’m ready for the next chapter… whatever it may hold!” Jarrett also congratulated Avivi on taking the reins, writing, “I’m confident her breadth of experience across so many world-class agencies and companies will bring tremendous value to our brand-building strategy and capabilities moving forward.” Avivi joins Bayer fresh off a yearlong stint as chief marketing officer of Advance Auto Parts, which followed about three years spent as marketing chief of another auto parts company, Tenneco. Rounding out her nearly 30-year career in marketing are leadership roles at consumer goods giants Kimberly-Clark and Procter & Gamble, and at agencies including BBDO, Young & Rubicam (now part of VMLY&R) and DMB&B, prior to its acquisition by Publicis. In her new position, Avivi will spearhead North American marketing efforts for Bayer’s range of consumer brands. She’ll report to Dave Tomasi, president of Consumer Health, North America for Bayer. “I’m excited to leverage my passion for building consumer-led, purpose-driven brands across the Consumer Health portfolio, which includes many brands that I know and love, like Claritin, Aspirin, and Midol,” she said in the announcement. Avivi’s appointment is the latest in a spate of recent executive moves for Bayer’s consumer health department. Her new boss, Tomasi—also a Procter & Gamble alum—took on the president role just last summer, following three years as chief commercial officer for the North American consumer health segment. And earlier this year, Bayer announced a new head of the global consumer health business: Julio Triana, currently head of international commercial operations in Bayer’s pharma division, who’s set to take over the president title from Heiko Schipper on May 1. Those high-level switch-ups have taken place as Bayer continues to stave off calls for a separation of the consumer health business. During an investor day last month, CEO Bill Anderson said the company had considered selling off the division but has so far decided against it because of the sizable tax losses such a separation would bring and because the consumer health brands are still generating sold cash flow, among other reasons. This year, Bayer is expecting consumer health sales to grow between 3% and 6% while forecasting that pharma will stay flat or drop up to 4%.
