Abstract
-
▴ The methylphenidate transdermal system (MTS) patch is approved by the US FDA for use in children aged 6–12 years with attention-deficit hyperactivity disorder (ADHD). This delivery system permits sustained absorption of the drug through the skin and into the bloodstream. Methylphenidate (MPH) is a CNS agent thought to act on dopamine and noradrenaline (norepinephrine) pathways and thereby blocks the reuptake of these neurotransmitters into the presynaptic neuron.
-
▴ In children with ADHD, MTS patches releasing MPH doses of 10–30mg over a 9-hour period (12.5–37.5cm2 patch size) is steadily absorbed, with mean peak plasma concentrations of d-MPH (20–46.5 ng/mL) reached in ≊8 hours.
-
▴ In well controlled trials in children with ADHD, patients administered MTS patches releasing MPH 10–30mg over ≊9 hours showed significantly greater improvements in their ADHD symptoms than placebo recipients.
-
▴ MTS patches are generally well tolerated in paediatric patients with ADHD, with treatment-emergent events being similar in nature to those reported with oral MPH. The majority of adverse events were mild to moderate in intensity.
