Overview

Basic Info

SummaryDiphenhydramine (DPH) is an antihistamine and sedative mainly used to treat allergies, insomnia, and symptoms of the common cold. It is taken by mouth, injected into a vein, injected into a muscle, or applied to the skin. Maximal effect is typically around two hours after a dose, and effects can last for up to seven hours. It is a first generation H1-antihistamine and ethanolamine and works by blocking certain effects of histamine, which produces its antihistamine and sedative effects. Diphenhydramine is also a potent anticholinergic. Common side effects include sleepiness, poor coordination and an upset stomach.

The Effect of Dimenhydrinate on Postoperative Nausea and Vomiting After Abdominal Hysterectomy: Randomized-controlled Trial

The aim of this clinical trial is to learn if Dimenhydrinate works to prevent postoperative nausea-vomiting in adult women who undergoing abdominal hysterectomy. The primary question is: Does Dimenhydrinate lower the proportion of postoperative nauseavomiting during the day 1 after surgery. Researcher will compare Dimenhydrinate to a placebo (a-look-alike substance that contains no drug) which will give intravenously when the patient come back to the ward, to see if Dimenhydrinate work to prevent nauseavomiting during the postoperative day1. All participants will receive standard treatment during pre-operative, intra-operative and the immediate post-operative periods. Participants will receive Dimenhydrinate or placebo only one dose after discharge from the recovery room. During the day 1 postoperative, participants will report their symptoms and keep a diary of the number of tmes they use additional anti-emetic drugs.

Nausea and vomiting are considered common series side effects induced by chemotherapy treatment in cancer patients. This annoying side effect can impair the patient's compliance to cancer treatment and affect their quality of life. Dimenhydrinate and cinnarizine in combined pharmaceutical dosage form is used to control chemotherapy induced nausea and vomiting in cancer patients. For safety, selective spectrophotometric methods based on novel dual resolution strategies were introduced to estimate dimenhydrinate and cinnarizine in presence of their harmful impurities namely benzophenone and 1- (diphenylmethyl)piperazine, respectively. These methods namely, dual ratio difference (DRD), dual ratio extraction (DRE) and dual absorbance extraction coupled with dual ratio extraction (DAE-DRE) were successfully performed to simultaneously analyze the drug of interests dimenhydrinate and cinnarizine in their pure form, synthetic mixtures and in market dosage form. Linearity ranges were 6.0-60.0 μg/mL and 3.0-30.0 μg/mL for dimenhydrinate and cinnarizine, respectively with good recovery% of Mean ± SD for all the proposed methods 99.82 ± 0.48, 99.79 ± 0.40, 100.14 ± 0.82, 100.03 ± 0.69, respectively. ICH guidelines were adhered in accordance with confirming validation of the proposed methods where fulfilling results were accomplished. Various unified greenness and whiteness assessment tools, such as the chlorTox scale, greenness index via spider chart, AGREE (The Analytical Greenness Metric), green certificate, and the RGB12 algorithm were employed in this research to assess the greenness and sustainability of the introduced UV-spectrophotometric methods in comparison to the reported HPLC method. As a result, these methods hold significant potential for utilization in the quality control department of pharmaceutical companies, contributing to enhanced pharmaceutical product analysis and overall sustainability practices.

Chronic high-dose dimenhydrinate use contributing to early multifactorial cognitive impairment

Article

Author: Smith, Andrew L ; Dholakia, Saumil ; Walker, Lisa A S ; Fabiano, Nicholas

Dimenhydrinate is an over-the-counter antihistaminergic medication with anticholinergic properties used to treat nausea or motion sickness worldwide. There is a well-established correlation between the use of anticholinergic medications and dementia, however, it is unclear if a causal role exists. We report a case of minor neurocognitive disorder in a woman in her 40s with several years of high-dose daily dimenhydrinate abuse who subsequently developed significant delusional beliefs. Her clinical presentation was confounded by numerous other factors that could have impacted her cognition, such as a longstanding presumed learning disability, ankylosing spondylitis with adalimumab treatment, extensive cannabis use or potential development of a primary psychotic disorder. Her workup was within normal limits, and she has not responded to first-line antipsychotic medications to date. This case report adds to the growing evidence supporting concerns about potentially irreversible cognitive deficits in chronic misuse of anticholinergic agents, an association previously observed only in the elderly population.

Comparing Epley Maneuver, Betahistine, and Dimenhydrinate in the Treatment of Benign Paroxysmal Positional Vertigo: A Prospective Study

Article

Author: Noroozbeygi, Amin ; Masoomi, Mahya ; Dehkordi, Mahboubeh Adami ; Salarifar, Elnaz

Although the Epley maneuver is considered the primary treatment in BPPV, anti-vertigo medications are effective in residual symptoms. This study was designed to compare betahistine and dimenhydrinate plus the Epley maneuver and the Epley maneuver alone. This prospective cohort study was performed in Mashhad, Iran, from 2013 to 2015. 90 adult patients diagnosed with BPPV in hospitals and ENT clinics were selected through convenience sampling. Patients received betahistine 8 mg TDS or dimenhydrinate 50 mg once daily plus Epley or the Epley alone for four weeks. SF-36 and the DHI were used before and after the treatment. 49 were females (54.4%). The mean (SD) age was 47.9 (8.7) years. There was no significant difference between the groups in age (P = 0.753) and gender (P = 0.050).There were significant differences in all areas of SF-36 except for social activities in the dimenhydrinate group. There was a marginally significant difference between the betahistine and dimenhydrinate groups in role limitation due to physical health problems (P = 0.046). There were significant differences between the females and males in emotional well-being before and after treatment in the dimenhydrinate group (P = 0.014) and in terms of role limitation due to physical health problems in the Epley maneuver group (P = 0.022). Older patients in the betahistine group had better social activities after treatment (P = 0.048). In severe forms of BPPV, betahistine or dimenhydrinate might effectively reduce the symptoms.

Dramamine® Celebrates its 75th Anniversary by Reviving an Unexpected Partner: The Barf Bag

The nausea-fighting brand is highlighting the cultural impact of barf bags and ushering them into a new era with a documentary, a limited-edition collection of upcycled bags and a custom wearable art piece made from vintage bags TARRYTOWN, N.Y., April 3, 2024 /PRNewswire/ -- 1949 was a big year for barf, welcoming the invention of the barf bag and Dramamine®. Seventy-five years later, Dramamine, a Prestige Consumer Healthcare brand, thrives as the number one brand for motion sickness relief, but as Dramamine has risen in popularity, the use of barf bags has sadly diminished. To commemorate the joint anniversary, Dramamine® is breathing new life – not barf – into the paper product with a mission to save its fellow partner in puke. Continue Reading ‘The Last Barf Bag’ Campaign The Last Barf Bag: A Tribute to a Cultural Icon "The Last Barf Bag" campaign announced today by Dramamine®, alongside agency partners FCB Chicago, 360PR+ and The Shipyard, explores the cultural impact of a humble yet crucial American invention made all but defunct due to Dramamine's effectiveness in preventing unexpected upchucks. Through a new documentary, a collection of upcycled, repurposed bags and a pop-up museum exhibition, Dramamine is paying tribute to a once iconic part of our culture and history, nodding to the manufacturers, collectors, and nausea sufferers as they fill barf bags with new purpose and save their industry from irrelevance. "We're not saying that Dramamine has caused the demise of the barf bag, but we are saying that Dramamine is effective in minimizing their use, and we feel bad about that," said Erica Nesbitt, Senior Brand Manager of Dramamine at Prestige Consumer Health. "The 75th anniversary of both inventions felt like the right time to commemorate barf bags' contributions to culture and even rewrite what the future holds for them after Dramamine's impact has made their intended purpose all but obsolete." 'The Last Barf Bag' Documentary The documentary short film, The Last Barf Bag: A Tribute to a Cultural Icon, explores the cultural impact of a humble but crucially useful American invention. In it, the barf bag collectors and manufacturers whose passion can be credited to saving it from extinction, meet their unlikely ally: the makers of the anti-nausea medication that threatens its existence. Directed by the filmmaking collective Sunny Sixteen (Niles Jeran, Joshua Martin, Taylor Pendleton, and Caleb Babcock), The Last Barf Bag film introduces us to doctors, pilots, historians, collectors, brand managers, suppliers, flight attendants, and even regular people discussing their barf-worthy experiences. 'This is Not A Barf Bag' Limited Edition Collection Dramamine and barf bags have been fighting the good fight against nausea together, but the barf bag can make way for a purpose that goes way beyond catching upchucks. Consumers can get in on the crusade to save culture's cherished paper puke sacks by purchasing upcycled barf bags that can be used as puppets, chef's hats, popcorn bags, coloring canvases, vases and more. Each bag in its repurposed form will be available for purchase for $5, and bundles including a barf bag and Dramamine product will be $10 while supplies last. View the full collection here. Dramamine commissioned artist and creative director known for her appearance on NBC's Making It, Jessie Bearden, to display her craft on a new type of novel canvas…vintage barf bags. Bearden created a custom-made puffer coat using the colorful, patterned barf bags from around the world as material for a unique, only-of-its-kind item and exhibition piece. The puffer can be previewed at TheLastBarfBag.com today through April 17 at 12pm EST, when it will open up for one lucky consumer to secure the ultra-limited edition drop for just $7.50, a nod to the 75th anniversary milestone. "The unique look of vintage barf bags and their various colors and designs actually make a great template for a totally one-of-a-kind textile, and that's what inspired me to create a jacket," said Bearden. "I use a lot of unorthodox materials in my work, but a barf bag is a first! It makes me so happy knowing the piece will give a new life to these barf bags and I hope it serves as a conversation starter for the one lucky person who gets to wear it and spread the news of Dramamine's The Last Barf Bag project." Barf Bag Collection Exhibition Today in New York City for one day only, consumers and passersby can see The Last Barf Bag Exhibition in-person and watch an exclusive screening of the documentary on the day of its world premiere. The extensive collections of four of America's preeminent barf bag collectors will be on full display, including collections consisting of hundreds of bags collected over 5+ decades from around the world and even space. The exhibit will be open to the general public on April 3 from 12pm – 7pm at 437 N. Broadway. Following the exhibition, its collections and contents will be available to be viewed online.

Vanda Pharmaceuticals Reports Results from a Phase III study of Tradipitant in Motion Sickness

WASHINGTON, May 25, 2023 /PRNewswire/ -- Vanda Pharmaceuticals Inc. (Vanda) (Nasdaq: VNDA) today announced the results from its Phase III study of tradipitant in motion sickness, confirming the previously reported results demonstrating that tradipitant is effective in the prevention of vomiting associated with motion sickness. The Phase III study was conducted in real-world conditions on boats in the coastal waters of the United States (U.S.). The Motion Syros study was a multicenter, randomized, double-blind, placebo-controlled study where 365 participants embarked on boat trips under varied sea conditions and received tradipitant 170 mg, tradipitant 85 mg, or placebo. Study participants had a prior history of motion sickness and were distributed across thirty-four boat trips that took place between November 2021 and April 2023. Sea conditions and participant evaluation of the symptoms of motion sickness were recorded for each trip. The primary endpoint of the study was the effect of tradipitant on vomiting induced by motion sickness. Both 170 mg and 85 mg tradipitant doses were shown to be superior to placebo in preventing vomiting with only 18.3% and 19.5% of participants experiencing vomiting on tradipitant 170 mg and 85 mg respectively, as compared to 44.3% of participants on placebo (p < 0.0001 for both). Motion sickness remains an unmet need as various pharmacological and non-pharmacological interventions suffer from low efficacy, substantial side effects, or both. The U.S. Food and Drug Administration (FDA) has not approved a new medication for motion sickness in over forty years, since the approval of scopolamine, a transdermal patch placed behind the ear, in 1979. Vanda plans to continue the motion sickness clinical program and pursue FDA approval upon completion of additional efficacy and safety studies. Table 1: Results of Motion Syros study for the Overall population across all sea conditions Motion sickness Motion sickness is a disorder characterized by a constellation of symptoms, with nausea and vomiting being the primary ones1. Motion sickness has plagued travelers for thousands of years, as evidenced by the ancient Greek physician Hippocrates who wrote "sailing on the sea proves motion disorders the body"1. Historians theorize that motion sickness may have changed the fate of civilization on several occasions, notably the defeat of the Spanish Armada by the English in 1588 and the negative effects on Napoleon's camel corps during the Egyptian campaign in 17982. It is believed that a discrepancy between actual body position and perceived body position triggers the maladaptive response of motion sickness3. Approximately 30% of the general population is reported to suffer from motion sickness under ordinary travel conditions that include sea, air and land travel4. According to IQVIA data, approximately two to three million doses of Dramamine, a common motion sickness remedy, are purchased monthly in the U.S. Dramamine treated patients represent only a fraction of the people treated monthly for motion sickness. Motion sickness is one of the most prevalent episodic disorders in the world, whose prevalence has dramatically increased with world population mobility over the last 100 years. The U.S. Department of Transportation reports 10 billion trips per year in mass transit (buses and trains), with an additional 965 million passenger trips in domestic and international air travel5.
