Delving into the Latest Updates on Amitriptyline Hydrochloride with Synapse

Overview

Basic Info

SummaryAmitriptyline Hydrochloride, a small molecule drug, is a reuptake inhibitor targets the monoamine transporters. Developed by Merck and first approved on April 7th, 1961, the drug is used to treat a range of conditions such as neuralgia, depressive disorder, and nocturnal enuresis. The drug works by preventing the reuptake of neurotransmitters, particularly serotonin and norepinephrine, which can lead to an increase in their concentration in the brain and subsequently enhance mood. Amitriptyline Hydrochloride is available in the form of oral tablets, which should only be used under the strict guidance of a healthcare provider. Patients must be aware of potential side effects such as dry mouth, constipation, and drowsiness, which can manifest in some individuals. The drug's administration should be closely monitored and individualized to ensure its safe and effective use. In conclusion, while Amitriptyline Hydrochloride presents an effective medication for managing certain neurological and mood disorders, patients must exercise caution and adhere to the recommended usage guidelines.

Review

Author: Zheng, Hui ; Hua, Can ; Li, Xin-Yu ; Pantila, Kulachai ; Chen, Bo-Zhu ; Xie, Chao-Rong ; Lin, Li ; Tao, Qing-Feng ; Wang, Zhen-Zhi ; Mou, Jian-Jiao

BACKGROUND:

Tension-type headache (TTH) is the most common neurological disorder. The comparative effect of pharmacological interventions for TTH prophylaxis remains unclear. We aimed to assess the comparative effects of pharmacological interventions in the prophylactic treatment of TTH.

METHODS:

Ovid Medline, Embase, and Cochrane were searched from inception to 12 December, 2025. Randomized controlled trials (RCTs) of medications compared to placebo or another medication for preventing TTH were included. The primary outcome was headache days per month. A Bayesian random-effect model was employed as the primary analysis of chronic TTH.

RESULTS:

Thirty-five RCTs were included, 33 (88.6%) RCTs involved chronic TTH patients, and 24 RCTs provided available data for meta-analysis. Amitriptyline 100 mg presented more reduction of monthly headache days than placebo at 4 and 8 weeks (4 weeks: MD -6.59, 95% CrI -11.22 to -0.64; 8 weeks: MD -6.14, 95% CrI -10.27 to -0.87). BTX-A 100 U can reduce monthly headache days (MD -3.79, 95% CrI -7.16 to -0.33). Amitriptyline 100 mg was the highest-ranked treatment for monthly headache days at 4 (SUCRA 0.85), 8 (SUCRA 0.85), and 24 (SUCRA 0.87) weeks; 12 weeks was lidocaine 25 ml (SUCRA 0.75). Amitriptyline 100 mg and BTX-A 500 U showed a higher adverse event rate than placebo.

CONCLUSION:

Amitriptyline 100 mg and BTX-A 100 U may be options to reduce monthly headache days in patients with chronic TTH. Given the low to very low certainty of evidence, high risk of bias, and high heterogeneity, more studies are needed.

Efficacy and Safety of Melatonin in Migraine Prophylaxis: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Review

Author: Khatatbeh, Abdallah Ahmad ; Abbas, Abdallah ; Aldemerdash, Ahmed ; Abouelmagd, Moaz Elsayed ; Monteith, Teshamae S ; Allam, Salma ; Osman, Ahmed S A ; AlEdani, Esraa M ; Aldemerdash, Mohamed A

Abstract:

Background:

Migraine is a chronic, disabling brain disorder. Melatonin, a circadian regulator with anti-inflammatory and antinociceptive actions, has been proposed for migraine prevention. We evaluated the efficacy and safety of melatonin for prophylaxis.

Methods:

We systematically searched PubMed, Cochrane, Scopus, Embase, and Web of Science (September 29, 2024) for randomised controlled trials (RCTs) comparing melatonin with placebo or other active drugs. Outcomes were analysed as change from baseline to last follow-up using mean differences (MD) or risk ratios (RR) with 95% confidence intervals (CI).

Results:

Nine RCTs ( n = 788) were included. Versus placebo, melatonin reduced attack duration (MD -4.98 h; 95% CI -9.30 to -0.67; p = 0.02), headache days (MD -1.54 days; 95% CI -2.50 to -0.58; p < 0.01), headache severity (MD -2.08; 95% CI -2.91 to -1.26; p < 0.01), and analgesic use (MD -1.38; 95% CI -2.41 to -0.36; p < 0.01). Melatonin also increased the response rate (≥ 50% reduction in monthly headache frequency) (RR 1.38; 95% CI 1.11–1.70; p < 0.01) and improved sleep quality (PSQI: MD -1.64; 95% CI -2.85 to -0.42; p = 0.008) and disability (MIDAS: SMD − 4.07; 95% CI -5.45 to -2.69; p < 0.001). Compared with amitriptyline, melatonin was generally less effective for attack duration and severity, with no consistent advantage on analgesic use or response; however, melatonin showed a more favourable tolerability profile, including lower risk of sleepiness (RR 0.49; 95% CI 0.28–0.87; p = 0.01).

Conclusions:

Melatonin demonstrates benefits over placebo for reducing migraine burden and improving patient-reported outcomes, with a favourable safety profile. While amitriptyline remains more potent for several efficacy endpoints, melatonin represents a reasonable preventive option, particularly as an adjunct during titration of first-line agents. Further head-to-head trials with standardised dosing and longer follow-up are warranted.

Development of a standardized routine workflow for entomological and toxicological analysis using larvae of two forensically relevant fly species (Diptera, Calliphoridae)

Article

Author: Wissenbach, Dirk K ; Siemon, Laura ; Niederegger, Senta

For more than four decades, no standardized study design or workflow has been established for systematic entomotoxicological research in forensic casework. This study aimed to develop a universal rearing protocol for fly larvae grown on drug-spiked tissue surrogate and a standardized workflow for the qualitative analysis of pharmacologically active compounds (PACs) in insects of different developmental stages. Larvae of Protophormia terraenovae and Lucilia sericata were reared on minced meat serving as tissue surrogate. First-instar larvae were transferred to minced meat spiked with diazepam, amitriptyline, pipamperone, or lamotrigine, each triturated with placebo tablets. Actively feeding and post-feeding third-instar larvae were soaked for 24 h in ethanol (30 mL, 70:30, v:v), and both the larvae and the soaking solution were analysed using LC-MS/MS. The larval extraction method was optimized by replacing pure acetonitrile with an acetonitrile-methanol mixture and introducing centrifugation at -10°C. PAC detection was achieved in both larvae and soaking solution, confirming the sensitivity and applicability of the method. The workflow was further validated using authentic postmortem case samples. These findings demonstrate that ethanol-soaked larvae can be used effectively for both toxicological and entomological analyses. Overall, this study provides a universal and standardized workflow that simplifies and strengthens the application of entomotoxicology in forensic casework.

Wisp Launches Comprehensive Migraine Care Vertical, Innovating Category with First-Ever, Asynchronous Care

NEW YORK--(BUSINESS WIRE)--Wisp, the largest pure play women's telehealth company in the U.S., today announced the launch of a dedicated migraine care vertical, consisting of online consults, prescription medications, and ongoing follow-up to help patients manage and prevent migraines. Wisp’s migraine specialists, certified by the National Headache Foundation, create customized treatment plans, expanding access to affordable, convenient care for patients wherever they are. Migraines affect one in five women — occurring nearly three times as often in women as in men — yet timely access to care remains a major barrier. On average, patients wait 34 days to see a neurologist, and in some cases, more than 90 days. Wisp’s new offering enables patients to receive care in 72 hours or less. “Migraine care is the natural next step for Wisp,” said Monica Cepak, CEO of Wisp. “Only one in four adults with episodic migraines receive diagnosis and treatment, and our patients continue to ask for treatment options. We’re delivering on our promise, with diagnoses made online, to democratize access to care, breaking down barriers so women can enjoy more pain-free days without the long wait times or high costs.” Wisp’s migraine care program includes: Migraine Consults ($60): Initial consults repeat every 6 weeks until the patient is on a stable dose. Quarterly Check-Ins ($30): Once stabilized, patients check in every 3 months for prescription refills. Prescriptions for Immediate Relief: Imitrex (Sumatriptan), Maxalt (Rizatriptan), Zomig ODT (Zolmitriptan). Anti-Nausea Medications: Zofran ODT (Ondansetron), Reglan (Metoclopramide). Preventive Medications: Topamax (Topiramate), Toprol XL (Metoprolol XL), Elavil (Amitriptyline), Lexapro (Escitalopram), Paxil (Paroxetine), Effexor ER (Venlafaxine ER). Patients begin with a $60 consult, complete a short intake form, and upload brief videos to help diagnose and assess eligibility. From there, a licensed provider reviews their medical history and intake to recommend a treatment plan, which may include immediate relief, anti-nausea, or preventive medications. Prescriptions are then sent the same day to the patient’s local pharmacy, with no insurance needed. “Migraines can be incredibly disruptive, but they are also very manageable with the right treatment plan,” said Dr. Jennifer Peña, Chief Medical Officer at Wisp. “Our approach provides patients with timely access to providers, tailored treatment options, and ongoing support so they feel empowered to take control of their health.” This launch follows Wisp’s recent expansion of its weight care vertical, furthering the company’s mission to provide affordable and accessible care for women across all life stages. From sexual and reproductive health to at-home diagnostics, fertility, menopause, to weight care and now migraine management, Wisp is continuing to build the most comprehensive platform designed for the unique needs of women. About Wisp: Wisp is the largest pure play women’s telehealth provider in the U.S., serving more than 1.5 million patients nationwide. Offering discreet, online care and a comprehensive range of first-to-market products, Wisp addresses women’s health needs across every stage of life—from birth control to fertility, menopause, STI testing, and more.

Some Antidepressants Linked to Weight, Heart Health Changes

THURSDAY, Oct. 23, 2025 — Antidepressants are widely used to treat depression and anxiety , but a new study finds that some of these medications can cause noticeable changes in weight, heart rate and cholesterol levels. The study, published Tuesday in The Lancet , analyzed data from more than 58,000 participants to compare 30 different antidepressants or a placebo for an average of eight weeks. Researchers found what they called “clinically significant” differences in how each medication affected the body’s metabolism and blood flow. For example, people taking maprotiline gained an average of 4 pounds, while nearly half of users of amitriptyline experienced some weight gain. In contrast, agomelatine was linked to an average weight loss of 5.5 pounds among 55% of participants. Heart rate changes also differed. Some drugs, like nortriptyline , increased heart rate by about 14 beats per minute, while fluvoxamine caused a decrease of around 8 beats per minute. Researchers emphasized that while these findings highlight important differences, antidepressants remain effective treatments for depression and anxiety . The results show the need for personalized prescriptions so that doctors can better match a drug to patient’s health needs. "We do know that these medications are life-saving and life-changing, but they can have variation from person to person depending on a person's metabolism, their age (and) what other medications they're on," psychiatrist Dr. Sue Varma told CBS News after reviewing the findings. She noted that untreated depression can also cause physical changes like weight gain or loss, so it’s important to “weigh the risks and the benefits” of starting medication. Varma added that doctors should discuss possible side effects with patients before prescribing antidepressants and regularly monitor for any changes. "Let's not cause panic, but these medications do have really important side effects," Varma told CBS News. Sources CBS News, Oct. 22, 2025
