Ischemic Colitis Reporting Across the Triptan Class: A Cross-Database Analysis With FDA Label Review (ACG 2026) - " We queried the FDA Adverse Event Reporting System (FAERS) and WHO VigiBase on 5/1/2026 for IC reports associated with sumatriptan, naratriptan, rizatriptan, zolmitriptan, almotriptan, eletriptan, and frovatriptan... Sumatriptan had the highest absolute IC case volume (FAERS: 87 cases; VigiBase: 114 cases) consistent with its dominant overall reporting volume. Rizatriptan was the only agent with significantly elevated IC reporting proportions in both FAERS (1.76% vs 0.79%, p=0.0007) and VigiBase (0.55% vs 0.31%, p=0.009). Frovatriptan was elevated in FAERS only (4.48% vs 0.85%, p=0.020)."

The Remote Electrical Neuromodulation (REN) wearable reduces medication use for the treatment of chronic pain in migraine patients (PAINWeek 2026) - "Medication types included three categories that were presented to patients using commercial drug names: (1) over-the-counter (OTC; e.g. Advil, Excedrin, Tylenol), (2) first-line prescribed medications including oral triptans (e.g. Imitrex, Maxalt, Relpax) and oral medication for nausea (e.g. Zofran, Reglan, Compazine), (3) second-line prescribed medications including nasal/injectable triptans (e.g. Tosymara, Onzetra, Zembrace, Zoming) and branded new generation medications (Reyvow, Nurtec, and Ubrelvy). Data from 31,516 migraine patients who conducted 148,705 REN treatments were analyzed. Treatment-level analysis showed that 71.1% of the treatments were performed without the use of any prescribed medications (50.6% REN alone, 14.4% REN + OTC meds), while 28.9% were conducted in conjunction with first- or second-line prescribed medications. A patient-level analysis looked at a subset of 2,653 patients who performed at least 10 REN treatments each, in which they reported..."

Clinical Details of Low-Frequency Hearing Loss Observed in Autosomal Dominant MYO7A-Associated Hearing Loss Patients. (PubMed, Genes (Basel)) - "In this study, we were able to clarify the specific features of MYO7A-related low-frequency hearing loss in a significant number of patients. In particular, we clarified the details of hearing deterioration at each frequency. Our findings will be useful for providing more appropriate treatment and follow-up for MYO7A-associated low-frequency hearing loss."

Investigating organic cation transporter 1 in drug interactions: New findings from in vitro and in vivo cynomolgus monkey studies. (PubMed, Drug Metab Dispos) - "Transport assays in transfected human embryonic kidney 293 cells showed that sumatriptan, fenoterol, metformin, quinidine, and 1-methyl-4-phenylpyridinium were transported by cOCT1 at rates comparable to hOCT1 (less than 2-fold difference)...Consistent with our in vitro findings, coadministration of OCT1 inhibitors (axitinib, nintedanib, and erlotinib) significantly increased the systemic exposure of sumatriptan in monkeys. These findings offer valuable insights into the role of OCT1 in drug-drug interactions and highlight the potential of cynomolgus monkeys as a useful and potentially translational model for OCT1-mediated disposition and interactions."

Extracellular vesicle-mediated gene editing for the treatment of nonsyndromic progressive hearing loss in adult mice. (PubMed, Sci Transl Med) - "In the Myo7aWT/Sh1 mouse model of autosomal dominant progressive hearing loss, which may model MYO7A-associated DFNA11 hearing loss in humans, we demonstrated the effective delivery of RNPs by EVs into cochlear hair cells by cross-sectional and whole-mount confocal imaging. The injection of RNP-EVs via the posterior semicircular canal in 4-week-old Myo7aWT/Sh1 mice resulted in a reduction in Myo7aSh1 messenger RNA expression and evidence of hearing preservation, as measured by auditory brainstem responses, compared with untreated ears and EV only-injected mice. This study highlights the potential of μDES-produced RNP-EVs for gene editing as a treatment for progressive nonsyndromic hearing loss in patients."

Select autosomal dominant DFNA11 deafness mutations activate Myo7A targeting in epithelial cells. (PubMed, J Cell Sci) - "Our findings reveal that Myo7A targeting is regulated by specific IQ motifs within its lever arm, and that this regulation can function at least partially independent of its tail sequence. Importantly, we demonstrate that many of the DFNA11 deafness mutations reported in patients activate Myo7A targeting, providing a potential explanation for the autosomal dominant genetics of this form of deafness."

Acute Treatment of Migraine: What has Changed in Pharmacotherapies? (PubMed, Neurol India) - "Two new formulations of sumatriptan, DFN-11 (3 mg doses of subcutaneous sumatriptan) and DFN-02 (a nasal spray of sumatriptan 10 mg and a permeation-enhancing excipient), have been developed, and both of them showed a fast-onset action with efficacy for acute treatment of migraine with fewer adverse events...Only lasmiditan has progressed to phase III clinical trials and was finally approved by the Food and Drug Administration (FDA) for acute migraine treatment...Ubrogepant and rimegepant demonstrated statistically significant efficacy, and both were recently approved by the FDA. These 5-HT receptor agonists and CGRP receptor antagonists did not cause vasoconstriction, offering advantages over the current mainstay of specific acute migraine treatment. Overall, these new agents have expanded the available acute therapies for migraine treatment and will likely change the strategy with which we treat patients with migraine in the future."
