Methylphenidate is a cerebral stimulant that can interfere with sleep, it should therefore not be administered within 6 hours of bedtime. It may also cause nausea, anorexia (eating disorder), and dry mouth, which interfere with appetite and adequate food intake; therefore it should be administered after the child has taken breakfast. It should be taken exactly as prescribed by the nurse or specialists and not as a needed basis.
Answer:A submitter of a premarket notification submission (510(k)) must demonstrate to the Food and Drug Administration (FDA) that the “new device” is “substantially equivalent” (SE) to a legally marketed predicate device. This guidance is intended to help 510(k) submitters demonstrate substantial equivalence. This guidance does not add new regulatory requirements for submitters, it does not change the 510(k) premarket review standard nor does it create extra or new burdens on what has traditionally been submitted in 510(k)s. FDA developed this guidance to improve the predictability, consistency, and transparency of the 510(k) premarket review process. Furthermore, this document is intended to serve as an aid for evaluating the benefit-risk profile of a new device in comparison to the predicate device.
