Long-term treatment outcomes with lisdexamfetamine dimesylate for adults with attention-deficit/hyperactivity disorder stratified by baseline severity

Abstract

Some aspects of these analyses (e.g., open-label design without placebo control, inclusion and exclusion criteria of the demographic profile of participants, and the post hoc nature of the statistical analysis) limit interpretation. However, long-term LDX treatment demonstrated increased degree of symptom improvement with greater baseline symptom severity. Rates of clinical response and symptomatic remission tended to be greater for those with greater baseline severity. LDX demonstrated a safety profile consistent with long-acting stimulant use.
