Novartis
  Purpose

Currently two different brands of modified-release formulations are providing 50% immediate release beads/pellets and 50% extended release beads/pellets, resulting in a rapid onset and dual peak concentrations of plasma methylphenidate. One is manufactured by Novartis, the other one by Medice (Germany).

The objective of the study is to test the hypothesis that the Novartis product is superior to placebo and is clinically not inferior to the formulation manufactured by Medice.


Condition Intervention Phase
ADHD Drug: Methylphenidate hydrochloride Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment

Criteria

Inclusion Criteria:

Patients who meet all of the following inclusion criteria will be eligible for enrollment in the study:
