Woburn, MA — April 6, 2026 — Azurity Pharmaceuticals, Inc. announced that ARYNTATM (lisdexamfetamine dimesylate) Oral Solution is now available in the United States for treating ADHD in adults and pediatric patients 6 years and older. Arynta, a ready-to-use lisdexamfetamine oral solution that may be stored at room temperature between 68°F to 77°F (20°C to 25°C),1 received FDA approval in June 2025. “Azurity Pharmaceuticals is proud to offer Arynta as an option for patients who need or prefer an oral liquid and are seeking flexibility in their treatment options,” said Ronald Scarboro, CEO of Azurity Pharmaceuticals. In pivotal Phase 3 clinical trials that evaluated the efficacy and safety of lisdexamfetamine across pediatric and adult patient populations, lisdexamfetamine demonstrated statistically significant efficacy for the core symptoms of hyperactive-impulsive and inattention in ADHD.1 As a prodrug of amphetamine, Arynta delivers reliable symptom control for up to 13 hours in children and up to 14 hours in adults, and its safety and tolerability profile is similar to that of other stimulant medication.1-5 Please read the full Prescribing Information, including Boxed Warning, and additional safety information at www.arynta.com. Azurity Pharmaceuticals is committed to serving overlooked patients, including those who have difficulty swallowing capsules or prefer a liquid form. It is reported that approximately 70% of children and about 30% of adolescents refuse or have difficulty swallowing tablets or capsules.6 Certain patient populations are more impacted than others. For example, about 40% of children with autism also have ADHD and many children with autism struggle with food texture hypersensitivity, which may make taking medication in capsule and sprinkle form a challenge.7-10 Arynta helps to address this need as part of Azurity’s innovative dose-form solutions.

TUESDAY, March 3, 2026 — College students using the ADHD drug Adderall as a study aid could be harming their heart health, a new Mayo Clinic study warns. A single 25-milligram dose of Adderall can cause a person’s heart rate and blood pressure to surge if they’re not used to taking the medication regularly, researchers found. "The average heart rate increase on standing was 19 beats per minute before Adderall. After taking Adderall, that response doubled to 38 beats per minute," lead researcher Dr. Kiran Somers said in a news release. He’s a resident physician in family medicine at the Mayo Clinic in Eau Claire, Wisconsin. Adderall – a combination of amphetamine and dextroamphetamine – is safe and effective when prescribed for ADHD, researchers said in background notes. However, illicit use of the drug has increased, mainly among students who’ve heard it can increase their alertness and concentration, according to American Addiction Centers . Prior studies have found that 23% to 43% of college students have turned to Adderall or other stimulant medications during times of high academic stress, researchers said. “We have seen an increase in nonmedical Adderall use, but many users are unaware that it can place acute stress on the cardiovascular system," senior researcher Dr. Anna Svatikova , a cardiologist at the Mayo Clinic in Rochester, Minnesota, said in a news release. For the new study, researchers recruited 30 healthy people who’d never had Adderall and were not suffering from ADHD. Each person randomly swallowed either a 25-mg dose of Adderall or a placebo tablet. Reading showed that their blood pressure and heart rate spiked within three hours of taking Adderall, compared to placebo. The drug also caused a surge in blood levels of the “flight-or-fight” stress hormone norepinephrine, researchers found. “We found that even in individuals with no prior exposure, a 25 mg dose triggers significant increases in blood pressure, heart rate and activation of the body’s stress-response system,” Svatikova said. These effects could be made even worse if Adderall is taken with energy drinks or other caffeinated beverages, potentially increasing young people’s odds of a potentially fatal heart rhythm problem, researchers said. However, more research is needed to understand the short- and long-term risks of illicit Adderall use among young people, researchers said. "These results demonstrate measurable, acute cardiovascular effects of Adderall used by those not regularly using Adderall prescribed for specific medical reasons,” Somers said.
