Effects of Application to Two Different Skin Sites on the Pharmacokinetics of Transdermal Methylphenidate in Pediatric Patients with Attention-Deficit/Hyperactivity Disorder

Abstract

Objective: This study was conducted to quantify the rate and extent of methylphenidate (MPH) absorption from a transdermal system when applied to two different skin sites in pediatric subjects with attention-deficit/hyperactivity disorder (ADHD). Methods: In an open-label, single-dose, randomized, two-way crossover study, children (6–12 years) with ADHD were randomized to wear one MPH transdermal system (MTS) on the hip area or on the scapular area for 16 hours. The following week, subjects were crossed over to the opposite application site. Serial blood samples were collected after each MTS application and pharmacokinetic (PK) parameters for d,l -MPH were calculated. Worn MTS units were assayed to calculate the Apparent Dose absorbed from MTS. Results: PK analyses included 23 subjects. Hip and scapular application resulted in quantifiable levels of d,l -MPH, with approximately 31% higher bioavailability upon hip application. Logarithm transformed mean ratios for area under the curve (AUC) and C max indicated a lack of equivalence between the two sites. Conclusion: MTS applied to both hip and scapular areas resulted in quantifiable plasma levels of d,l -MPH. Bioavailability of MPH from the same transdermal delivery system appears to differ substantially when applied to two different skin surfaces in young children but with similar overall skin effects assessments.

  • Greater absorption of methylphenidate occurs when the patch is applied to the buttocks rather than to the subscapular area.

    “Greater absorption of medication occurs when the patch is applied to the buttocks rather than to the subscapular area [47].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
