The primary(More)
OBJECTIVE The comparison of the efficacy of Medikinet(®) retard and Concerta(®) trial was a multisite, randomized, double-blind, crossover trial that aimed at comparing the effects of two different modified release methylphenidate preparations (Medikinet retard: 50% immediate release (IR); Concerta: 22% IR) in a natural setting across the day in 113(More)
OBJECTIVE To assess bioequivalence between Equasym Retard and Medikinet retard containing 20 mg methylphenidate (MPH) hydrochloride in a fed state. MATERIALS Equasym Retard 20 mg capsules (UCB, Monheim, Germany) and Medikinet retard 20 mg capsules (Medice, Iserlohn, Germany). METHODS This was an open, single-center, randomized, 2-period, 2-sequence,(More)
OBJECTIVE To assess bioequivalence between an intact capsule and the content of a capsule sprinkled on applesauce. MATERIALS Medikinet retard 20 mg capsules were obtained from Medice (Iserlohn, Germany). METHODS This was a single-center, completely randomized, open, 2-period, 2-sequence, balanced crossover study with a washout period of 1 week between(More)

After 4 weeks, each patient was clinically and endoscopically assessed. Failure to heal required a(More)

Examiners, blinded to the children's group status, coded the children's activities during the 6.5-minute play(More)
