Relaxing effect of ramelteon on the uterus of non-pregnant and pregnant rats: Importance of melatonin receptors and BKCa

Article

Author: Ducza, Eszter ; Szűcs, Kálmán F ; Barna, Tamara ; Bagyánszki, Mária ; Alasaad, Kármen Mirella ; Schaffer, Annamária ; Bódi, Nikolett ; Gáspár, Róbert

AIMS:

Our objective was to measure the effect and mechanism of action of the melatonin agonist ramelteon in rat uteri from non-pregnant and pregnant rats in vitro.

MAIN METHODS:

KCl-induced contractions of non-pregnant and pregnant uterine rings samples (whole or endometrium-denuded) were investigated in an organ bath in the presence of ramelteon alone or with melatonin (MT) receptor antagonist luzindole or with the high-conductance calcium-dependent potassium channel (BK_Ca) blocker paxilline. The changes in melatonin receptor expressions were followed by RT-PCR, Western blot, and fluorescent immunohistochemistry.

KEY FINDINGS:

Ramelteon inhibited uterine contractions, with the degree of inhibition being greater towards the end of pregnancy. Both MT₁ and MT₂ receptors were identified in all uteri (except gestational day 5); they do not participate in the relaxing effect of ramelteon in non-pregnant and 5-day pregnant samples. The activation of BK_Ca appears to be a constitutive component of the uterorelaxant action of ramelteon throughout the gestational period. Endometrial melatonin receptors have a significant impact in mediating relaxation in mid- and late pregnancy.

SIGNIFICANCE:

Ramelteon has a relaxing effect on mid- and late-pregnant uteri through at least a dual mechanism of action. The alteration of melatonin receptors during the gestational period raises the possibility that melatonin receptors might be potential drug targets for the treatment of premature labour.

Ramelteon coordinates theta and gamma oscillations in the hippocampus for novel object recognition memory in mice

Article

Author: Suzuki, Haruka ; Izumo, Kano ; Matsumoto, Nobuyoshi ; Ikegaya, Yuji ; Iijima, Sena ; Takeda, Kinjiro ; Nagahiro, Takeshi ; Watanabe, Kisa

Object recognition memory is an animal's ability to discriminate between novel and familiar items and is supported by neural activities in not only the perirhinal cortex but also the hippocampus and prefrontal cortex. Since we previously demonstrated that ramelteon enhanced object recognition memory in mice, we sought neural correlates of the memory improvement. We recorded neural activity in the hippocampus and prefrontal cortex of mice while they performed a novel object recognition task. We found that theta oscillations in the hippocampus were enhanced when ramelteon-treated mice explored both novel and familiar objects. Moreover, we showed high coherence in phases at low gamma frequencies between the hippocampus and prefrontal cortex. We assume that theta enhancement is indicative of increased cholinergic activity by melatonin receptor activation. High coherence of low gamma oscillations between the hippocampal and prefrontal network in ramelteon-treated mice sampling novel objects suggests better cognitive operations for discrimination between novelty and familiarity. The current study sheds light upon physiological consequences of melatonin receptor activation, further contributing improved cognitive functions.

Protective efficacy of ramelteon on methotrexate-induced DNA damage

Article

Author: Aslan Koşar, Pınar ; Yavuz Türel, Gülçin

Ramelteon (RMLT) is a melatonin receptor agonist that it has antioxidative and anti-inflammatory effects associated with DNA damage through different mechanisms of action. In this regard, we investigated the potential usefulness of RMLT as a protective agent against methotrexate (MTX)-induced DNA damage. Four groups were constituted from 32 Wistar albino rats: Negative control, RMLT, MTX, and MTX + RMLT. Twenty mg/kg MTX (i.p., single dose) and RMLT 10 mg/kg (oral, 7 days) was administered. Comet assay was used and the parameter %TailDNA was used to detect DNA damage. %TailDNA was 4.90 ± 0.19 in the control group, 7.85 ± 0.33 in the MTX group, 5.49 ± 0.24 in the RMLT group, and 5.86 ± 0.23 in the MTX + RMLT group. While there was a significant increase in DNA damage in the MTX-treated group compared to the control group, there was a significant reduction in DNA damage in the MTX + RMLT group, compared to the MTX group (p < 0.001). In conclusion, it was observed that combined treatment with RMLT significantly reduced MTX-induced DNA damage.

Supernus Announces Label Update for Non-Stimulant ADHD Treatment, Qelbree®, Including New Pharmacodynamic Data and Information for Breastfeeding Women

Updated label includes new data in Section 12.2, detailing serotonin 5-HT2C partial agonist activity and norepinephrine transporter inhibition, highlighting Qelbree’s multimodal pharmacodynamicsQelbree is the first ADHD treatment to meet its post marketing requirement and receive labeling approval following the 2019 FDA guidance on Clinical Lactation Studies1 ROCKVILLE, Md., Jan. 27, 2025 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (Nasdaq: SUPN), a biopharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, announced that the U.S. Food and Drug Administration (FDA) has approved an update for the label for Qelbree (viloxazine extended-release capsules) to include new pharmacodynamic data in Section 12.2. The updated label describes viloxazine’s partial agonist activity at the serotonin 5-HT2C receptor and inhibition of the norepinephrine transporter, reinforcing its multimodal pharmacodynamic profile. The mechanism of action of Qelbree, though unclear, is thought to be through inhibiting the reuptake of norepinephrine. Additionally, the updated label now includes new lactation data for breastfeeding women with attention-deficit/hyperactivity disorder (ADHD), showing that the transfer of Qelbree into breastmilk is low. Qelbree is approved for use in patients ages 6 years and older with ADHD. “This label update and new data deepens our understanding of Qelbree, providing valuable insights to help support treatment decision-making for people living with ADHD,” says Dr. Stephen M. Stahl, M.D., PhD, DSc (Hon.) Distinguished Health Sciences Clinical Professor of Psychiatry and Neuroscience, University of California Riverside and Adjunct Professor of Psychiatry, University of California San Diego. “The updated pharmacodynamic data, which highlights viloxazine’s effects on the serotonin 5-HT2C receptor and inhibition of the norepinephrine transporter, adds depth to our understanding of Qelbree’s multimodal pharmacodynamics.” The update to include lactation data in the label (Section 8.2) follows the 2019 FDA guidance suggesting lactation studies be conducted to inform breastfeeding with drug use recommendations and is based on a study involving 15 healthy lactating women.¹ The study evaluated the secretion of viloxazine and its metabolite (5-HVLX-gluc) into breast milk following a multi-dose (600 mg daily for three days) regimen of viloxazine. Results showed that the estimated daily infant dose (using a nominal infant body weight of 6 kg) of viloxazine and 5-HVLX-gluc was 0.085 mg/kg and 0.00595 mg/kg, respectively, and the relative infant dose was approximately 1% and 0.07%, respectively, of the weight-normalized maternal daily dose (8.58 mg/kg) of viloxazine. These data support that the transfer of viloxazine into breastmilk is low. The study did not specifically evaluate the effects of viloxazine on breastfed infants or milk production, nor is there additional data regarding these effects. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Qelbree and any potential adverse effects on the breastfed child from Qelbree or from the underlying maternal condition. “By expanding Qelbree’s label to include new data on the pharmacodynamics and use in breastfeeding mothers, Supernus continues to empower healthcare providers and patients to make informed treatment decisions,” says Jack A. Khattar, President and Chief Executive Officer of Supernus Pharmaceuticals. “We are committed to building the body of evidence surrounding Qelbree’s use within the ADHD space and providing an effective treatment option for those living with ADHD.” INDICATION Qelbree® (viloxazine extended-release capsules) is a prescription medicine used to treat ADHD in adults and children 6 years and older. IMPORTANT SAFETY INFORMATION Qelbree may increase suicidal thoughts and actions, in children and adults with ADHD, especially within the first few months of treatment or when the dose is changed.

Busy Philipps Encourages Women to Take Charge of Their ADHD This Fall in Ongoing Collaboration with Supernus Pharmaceuticals and Qelbree

Ahead of ADHD Awareness Month, Busy is sharing her ADHD diagnosis and Qelbree® (viloxazine extended-release capsules) treatment story to empower women living with ADHD to advocate for their care.ADHD often presents differently in women than in men, which can make it more challenging to recognize in women and ultimately leaving them undiagnosed and untreated.1 ROCKVILLE, Md., Sept. 24, 2024 (GLOBE NEWSWIRE) -- In a continued collaboration with Supernus Pharmaceuticals, actress, author, podcaster, late-night host, and mom, Busy Philipps, is speaking up this fall about her ongoing journey with attention-deficit/hyperactivity disorder (ADHD), bringing awareness to the often-overlooked symptoms of the condition in women and Qelbree, a non-stimulant ADHD treatment that has benefitted her. With summer over and the school year now in full swing, the fall season brings for many adults a return to normal routines or schedules, as well as an opportunity for a fresh start. Busy knows first-hand just how difficult getting ‘back to schedule’ can be for the approximately 10 million adults living with ADHD, who may be experiencing symptoms of inattention, hyperactivity/impulsivity, or both.2 She’s sharing her story to help empower people, and especially women, living with ADHD to take action for a fresh start this fall and talk to their doctors about treatment options to help manage their condition. “For many years living with unmanaged ADHD, I’d often start a task and never remember to finish, frequently feeling restless and unable to stay still. I would ramble on, get easily distracted and have trouble multitasking, and with my busy lifestyle, it was a challenge,” says Busy. “Now that I’m taking Qelbree, I’m relieved that my ADHD symptoms are more manageable. I only wish I’d taken charge of my ADHD sooner. That’s why I’m sharing my story to raise awareness about ADHD and help others who may be struggling with their diagnosis find a treatment option that works for them like Qelbree has worked for me.” Qelbree is a novel, once-a-day, non-stimulant approach for patients 6 years and older with ADHD, and the first non-stimulant approved for adults with ADHD in 20 years. As a non-stimulant, Qelbree has no evidence of abuse or misuse and can be conveniently refilled without needing a new prescription each month. “As a leader in treating ADHD, Supernus is committed to providing treatment options and education to help people living with ADHD like Busy Philipps manage their ADHD symptoms,” says Jack A. Khattar, President and Chief Executive Officer of Supernus Pharmaceuticals. “We appreciate Busy’s continued support and willingness to share her ADHD story and experience with Qelbree, especially leading into ADHD Awareness Month.” For more information about Qelbree, visit Qelbree.com.
