Questions People Are Actually Asking

What exactly is Simtriyo (centanafadine) and how does it differ from other ADHD medications?▾

Sintriyo (centanafadine) is a newly FDA-approved non-stimulant medication for Attention-Deficit Hyperactivity Disorder (ADHD). Its primary difference lies in its mechanism of action: it's a norepinephrine and dopamine reuptake inhibitor (NDRI). This means it increases the levels of both norepinephrine and dopamine in the brain, which are neurotransmitters crucial for attention, focus, and impulse control. Unlike traditional stimulant medications such as methylphenidate or amphetamines, Simtriyo does not directly stimulate the central nervous system, which can be beneficial for patients who experience adverse side effects from stimulants or have co-occurring conditions like anxiety or certain cardiovascular issues. It also differs from other non-stimulants like atomoxetine, which primarily targets norepinephrine, by also influencing dopamine levels.

Who is Simtriyo intended for, and can both adults and children use it?▾

Yes, Simtriyo is approved for a broad patient population, specifically for the treatment of ADHD in both adult and pediatric patients. This broad approval is significant because it means that a wide range of individuals, from children navigating school to adults managing careers and families, could potentially benefit from this new therapy.
