Amiloride Hydrochloride as an Effective Treatment for ADHD

Stopped early · Early Phase 1 · Has a placebo group

Conditions studied: ADHD

In brief

The investigators are proposing to test a medication derived from our prior studies of the gene SLC9A9. This one gene makes NHE proteins that control how we learn and remember items, which is impaired in ADHD and may cause an inability to plan, prioritize, self-monitor,inhibit, initiate, self-correct, or control one's behavior. The investigators now propose to investigate the therapeutic utility of an NHE inhibitor, amiloride hydrochloride, for the treatment of attention deficit hyperactivity disorder (ADHD) in medication-naïve adults with ADHD.

• ability to swallow pills;
• ability to report reliably, understand the nature of the study and sign an informed consent document as determined by the study psychiatrist
