What it is used for
Methylphenidate transdermal system is indicated for the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in pediatric patients 6 to 17 years of age. Limitations of Us e The use of methylphenidate transdermal system is not recommended in pediatric patients younger than 6 years of age because they had higher plasma exposure and a higher incidence of adverse reactions (e.g., weight loss) than patients 6 years and older at the same dosage.

Description
Methylphenidate transdermal system is an adhesive-based matrix transdermal system containing methylphenidate that is applied to intact skin. The chemical name for methylphenidate is α-phenyl-2-piperidineacetic acid methyl ester. It is a white to off-white powder and is soluble in alcohol, ethyl acetate, and ether. Methylphenidate is practically insoluble in water and petrol ether. Its molecular weight is 233.31. Its empirical formula is C 14 H 19 NO 2. The structural formula of methylphenidate is: Transdermal System Components Methylphenidate transdermal system contains methylphenidate in a polyisobutylene adhesive. The composition per unit area of all dosage strengths is identical, and the total dose delivered is dependent on the transdermal system size and wear time. Methylphenidate transdermal system consists of four layers, as seen in the figure below (cross-section of the transdermal system) Proceeding from the outer surface toward the surface adhering to the skin, the layers are a polyester/ethylene vinyl acetate laminate film backing and white ink which contains acrylic polymers, polyethylene wax, polytetrafluoroethylene, polyvinylpyrrolidone, sodium dioctyl sulfosuccinate and titanium dioxide, a solid matrix drug reservoir of methylphenidate, polyisobutylene adhesive, mineral oil and hydrophobic colloidal silica, a skin contact adhesive formulation of polyisobutylene adhesive, mineral oil and hydrophobic colloidal silica, and a fluoropolymer-coated polyester protective liner, which is attached to the adhesive surface and must be removed before the transdermal system can be used. The active component of the transdermal system is methylphenidate. The remaining components are pharmacologically inactive. Methylphenidate transdermal systems are packaged with an additional piece of protective film above the system within each pouch. This piece of protective film is removed and discarded at the time of use. Methylphenidate Structural Formula Four layers of patch and cross-section of the patch
