Delving into the Latest Updates on Mirtazapine with Synapse

Overview

Basic Info

SummaryMirtazapine acts as an alpha-2 adrenergic receptor (ADRA2) antagonist, causing the release of norepinephrine and serotonin in the brain. These neurotransmitters are essential in regulating mood and emotions. By increasing their release, mirtazapine helps to alleviate the symptoms of major depressive disorder, which has been marketed under various trade names such as Razapina and Reflex. Developed by Merck Sharp & Dohme, this drug was first approved in the United States, China, Germany, and South Korea.This drug is available in tablet form and should be taken orally. However, caution should be taken when using this drug as it may cause side effects such as drowsiness, weight gain, and dry mouth. Despite the possible side effects, mirtazapine has shown efficacy in the treatment of depression.

MALDI-TOF MS-based SNP assay used to determine the appropriate antidepression for Chinese patients

Article

Author: Huang, Shanqing ; Gan, Tongying ; Shang, Dewei ; Guo, Zhihao ; Zhang, Zi

Medicine remains the preferred primary treatment for depression, although some patients show remarkable individual variations in achieving satisfactory clinical outcomes during medication. Genetic polymorphisms cause approximately 40 % of individual differences in treatment response. Therefore, this study aimed to develop a technique to identify single nucleotide polymorphisms (SNPs) associated with the metabolism, effectiveness, and side effects of antidepressant medications in Chinese patients. Bibliometrics was used to search literature related to "depression" and "SNP" in Web of Science. The obtained SNP information was screened using the PharmGKB database. By designing and optimizing primers and conducting a compound amplification system, a method was established based on MALDI-TOF MS to detect polymorphisms associated with the antidepressant drugs, including sertraline, fluoxetine, citalopram, escitalopram, venlafaxine, fluvoxamine, paroxetine, and mirtazapine. The accuracy and sensitivity of the established method were verified by Sanger sequencing. A total of 10,043 articles were screened from the database, and 46 SNPs with a mutation frequency of >1 % in Asian populations and annotated with relevant clinical drugs were extracted from the PharmGKB database. This method was compared with the results of Sanger sequencing, and the accuracy of the detection results was 100 %. The MALDI-TOF MS-based SNP assay developed in this study can be a fast, convenient and effective way for patients to find the right medication for themselves. Moreover, we found that this SNP assay holds the promise of being a potential reference tool for assessing individualised differences in drug efficacy, not only for screening the causes of poor antidepressant efficacy in patients after taking medication, but also for advising physicians to understand individualised differences in drug efficacy.

Pharmacotherapy for behavioural manifestations in frontotemporal dementia: An expert consensus from the European Reference Network for Rare Neurological Diseases (ERN‐RND)

Article

Author: Vandenberghe, Rik ; Saracino, Dario ; Djamshidian, Atbin ; Capellari, Sabina ; Boban, Marina ; De Winter, François‐Laurent ; Rohrer, Jonathan ; Wittebrood, Casper ; Rodriguez, Eloy Rodriguez ; Cagnin, Annchiara ; González, Manuel Menéndez ; Levin, Johannes ; Reetz, Kathrin ; Graessner, Holm ; Rusina, Robert ; Krajcovicova, Lenka ; Reinhard, Carola ; Seelar, Harro ; Krüger, Johanna ; Van Langenhove, Tim ; Houot, Marion ; Hjermind, Lena E.

Abstract:

Background and Purpose:

Frontotemporal dementia (FTD) is a neurodegenerative disorder characterized by pervasive personality and behavioural disturbances with severe impact on patients and caregivers. In current clinical practice, treatment is based on nonpharmacological and pharmacological approaches. Unfortunately, trial‐based evidence supporting symptomatic pharmacological treatment for the behavioural disturbances in FTD is scarce despite the significant burden this poses on the patients and caregivers.

Method:

The study examined drug management decisions for several behavioural disturbances in patients with FTD by 21 experts across European expert centres affiliated with the European Reference Network for Rare Neurological Diseases (ERN‐RND).

Results:

The study revealed the highest consensus on drug treatments for physical and verbal aggression, impulsivity and obsessive delusions. Antipsychotics (primarily quetiapine) were recommended for behaviours posing safety risks to both patients and caregivers (aggression, self‐injury and self‐harm) and nightly unrest. Selective serotonin reuptake inhibitors were recommended for perseverative somatic complaints, rigidity of thought, hyperphagia, loss of empathy and for impulsivity. Trazodone was specifically recommended for motor unrest, mirtazapine for nightly unrest, and bupropion and methylphenidate for apathy. Additionally, bupropion was strongly advised against in 10 out of the 14 behavioural symptoms, emphasizing a clear recommendation against its use in the majority of cases.

Conclusions:

The survey data can provide expert guidance that is helpful for healthcare professionals involved in the treatment of behavioural symptoms. Additionally, they offer insights that may inform prioritization and design of therapeutic studies, particularly for existing drugs targeting behavioural disturbances in FTD.

Novartis and Viatris sued by estate of Henrietta Lacks, whose cells were extracted for research in 1951

A statue of Henrietta Lacks is the first public sculpture of a Black woman made by a Black woman in the U.K. Lacks' cancer cells changed the course of modern medicine after they were taken from her without her consent or knowledge in 1951. Lacks' estate has sued four biopharma companies, including Novartis and Viatris on Monday, for allegedly profiting off discoveries made with Lacks' cells The family of a Baltimore woman whose cells were extracted for medical research without her consent more than 70 years ago has filed another lawsuit against drugmakers that allegedly profited from the discoveries they made using her genetic material.The family of Henrietta Lacks has sued Novartis and Viatris, seeking a jury trial and the “full amount” of profits obtained through their use of the “stolen” cells, according to the lawsuit, which was filed Monday in federal court in Baltimore.“Medical research has a long, troubled history of exploiting Black individuals, and Henrietta Lacks’s story is a stark reminder of this legacy,” Ben Crump, a civil rights attorney representing the family, said in a release. “It is time for these corporations to be held accountable for their unjust enrichment and to provide the Lacks family with the recognition and compensation they deserve.”The lawsuit is the third filed by the family against a pharma company. Last year, Thermo Fisher came to a settlement for an undisclosed sum. Days later, the Lacks’ estate filed a similar suit against Ultragenyx over its production of viral vectors.Novartis said that it doesn’t comment on litigation. Viatris did not respond to a request for comment.The lawsuits harken to an era when racism was rampant in the healthcare system. They also open difficult questions for courts to consider as Lacks’ case traces to 1951 when doctors didn’t need patients' permission to harvest their cells. Lacks was a young mother of three in Baltimore when she developed cervical cancer. Tissue taken from a biopsy—before she died that same year at age 31—was saved and became the first human cells to grow and reproduce in lab dishes. Dubbed HeLa cells, they became the first “immortal human cell line” and important building blocks for scientific studies around the world, leading to the discovery of the polio and COVID vaccines, breakthroughs in genetic mapping and scores of other medical innovations.While Johns Hopkins never profited from HeLa cells, companies and other research organizations have developed thousands of patents using HeLa cells. Novartis holds “hundreds” of those patents, according to the lawsuit.“Novartis has utilized Mrs. Lacks’s genetic material extensively as a fundamental component in their research and development processes,” the lawsuit reads. “By using these cells, Novartis can efficiently test and refine their pharmaceutical compounds, accelerating the development of new drugs.”Novartis and Viatris have always been aware of the origin of Lacks’ cells, according to the lawsuit. In a 2021 website posting, the company cited Lacks’ story in announcing an initiative to address health disparities through “holistic community-based collective action.”Among the products Novartis has developed using HeLa cells, according to the lawsuit, are herpes drug Famvir, CAR-T therapy Kymriah and gene therapy Zolgensma. Viatris treatments cited in the suit include the depression drug mirtazapine and herpes drug Denavir.

The Most Common Depression Medications, Explained

FRIDAY, May 26, 2023 -- You've been diagnosed with depression. What's next? The cornerstone of treatment remains antidepressants, so it's likely your doctor will prescribe one for you, but which one might be best? You will join millions around the world who struggle with how to treat the mental health disorder. An estimated 3.8% of the global population experiences depression, according to the World Health Organization . The numbers are staggering, but when depression is left untreated, it can impair daily functioning, raise the risk of suicide and lower quality of life. Fortunately, there are many different types of antidepressants available, each with unique mechanisms of action, benefits and potential side effects. Here, experts will explore the most commonly prescribed depression medications, how they work and their common side effects. Depression medications Dr. Abid Nazeer, founder, chief medical officer and medical director of Advanced Psych Solutions in Naperville, Ill., stated, “If you don’t treat depression, there’s a risk that you may get through the day, but it will feel like a struggle. If it’s been adequately treated, you can have a much better day.” Meanwhile, Pardis Khosravi , a psychologist and clinical director at Children’s Health Council in California, said, “Depression is not something you can 'power through' or think your way out of with positive thoughts. It is a medical illness that left untreated can have a profound impact on your health, quality of life and daily functioning. Untreated depression increases the likelihood of risky behaviors such as substance use, self-harm and suicidal ideation and/or behaviors.” Although alternative therapies can be successful in treating depression, medication might become necessary in certain situations when other treatments have failed, depression symptoms interfere considerably with daily life, there is a history of mental health issues, or when a person feels too exhausted to pursue non-medication treatments. Here are some of the most common depression medications: Selective serotonin reuptake inhibitors (SSRIs) SSRIs are a class of medications used to treat depression by elevating serotonin levels in the brain, a crucial neurotransmitter that facilitates communication between nerve cells. The Mayo Clinic indicates that SSRIs prevent serotonin reabsorption into neurons, ensuring that more of the chemical messenger remains available to enhance signaling between brain cells. Additionally, SSRIs are known as selective agents because they primarily impact serotonin rather than other neurotransmitters. These SSRIs have received approval from the U.S. Food and Drug Administration for the treatment of depression: Citalopram (Celexa) Escitalopram (Lexapro) Fluoxetine (Prozac) Paroxetine (Paxil, Pexeva) Sertraline (Zoloft) While SSRIs effectively treat depression, they may also cause various side effects. Per an article published in the Primary Care Companion to the Journal of Clinic Psychology , SSRIs' most common side effects include gastrointestinal problems, sexual dysfunction, weight gain and sleep disturbances. Gastrointestinal side effects include nausea, diarrhea and abdominal pain, while sexual dysfunction includes decreased libido, erectile dysfunction and difficulty achieving orgasm. In rare cases, SSRIs may increase the risk of suicidal ideation, particularly in young people, some research has shown. Antidepressant medications SSRIs are not the only medications for depression: Tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs) work by affecting other neurotransmitters. SSRIs generally have fewer side effects than these older antidepressants and are typically the first-line treatment for depression. However, the choice of medication depends on individual needs, and health care providers may recommend different types of antidepressants based on the patient's specific symptoms and medical history. Monoamine oxidase inhibitors (MAOIs) MAOIs are another type of antidepressant medication that blocks the enzyme monoamine oxidase, which breaks down neurotransmitters such as serotonin, norepinephrine and dopamine. By increasing the levels of these neurotransmitters, MAOIs can alleviate symptoms of depression. Some of the most common MAOIs include: Phenelzine (Nardil) Tranylcypromine (Parnate) Isocarboxazid (Marplan) Selegiline (Emsam) — available as a transdermal patch These medications can be effective in treating depression. However, the Mayo Clinic states that they are generally not considered first-line therapy due to their potential for serious side effects and interactions with certain foods and medications. Atypical antidepressants According to Mental Health America , atypical antidepressants are a diverse class of medications used to treat depression that do not fit neatly into other categories of antidepressants. They work by targeting multiple neurotransmitters in the brain, including serotonin, norepinephrine and dopamine, to improve mood and ease symptoms of depression. Some of the most commonly used atypical antidepressants include: Bupropion (Wellbutrin) Mirtazapine (Remeron) Trazodone (Desyrel) Vilazodone (Viibryd) Vortioxetine (Trintellix) Bupropion is known for its unique mechanism of action, which involves increasing the levels of norepinephrine and dopamine in the brain. Mirtazapine works by increasing the release of both serotonin and norepinephrine, while trazodone primarily affects serotonin levels. Vilazodone and vortioxetine are newer medications that target multiple neurotransmitters and effectively treat depression. These medications may be useful for individuals who have not responded to other types of antidepressants or who experience side effects from other medications.
