Vílocsaín

Viloxazine is a selective norepinephrine reuptake inhibitor (NRI) that also modulates serotonergic activity as a 5-HT2B antagonist and 5-HT2C agonist. Originally used as an antidepressant in Europe (1974-2002), it was repurposed and FDA-approved in 2021 for ADHD treatment in the US under the brand name Qelbree. It is generally well-tolerated but may cause insomnia, irritability, somnolence, or gastrointestinal upset. Higher rates of suicidal thoughts and behaviors have been reported in pediatric patients, requiring close monitoring especially during initial treatment. Caution is advised in patients with liver or severe renal impairment, bipolar disorder, or those taking CYP1A2 substrates.
