✔ Mental alertness without strong euphoria
✔ Longer duration of action than methylphenidate  (~6-8 hours)
✔ Less rebound effects than amphetamines

Usage scenarios

  • ADHD-related studies (preclinical)

2. Experimental Applications

  • Productivity support (in controlled settings)

  • Study on fluorinated stimulants

Advantages

✅ Precise dosing  due to pellet form
✅ Longer duration of action  than regular methylphenidate
✅ Less recreational abuse potential  due to lack of strong euphoria
