Abstract. Valproic acid (VPA) is a widely prescribed medication that has traditionally been used to treat epilepsy, yet embryonic exposure to VPA increases the risk of the fetus developing neural tube defects (NTDs). While the mechanism by which VPA causes NTDs is unknown, we hypothesize that VPA causes dysmorphogenesis through the disruption ...Clomipramine is well absorbed orally but probably undergoes significant first-pass metabolism. Metabolism may be dose-related (capacity limited), which should be kept in mind when using large doses (eg, >150 mg/day). Due to enzyme inhibition, coadministration of valproic acid may produce elevated levels of clomipramine with resultant seizures.

Rationale Behind Withholding Tube Feeding The rationale behind withholding EN with drug administration is to either minimize or prevent drug-nutrient interactions. Specifically, it is the interactions that occur either in the delivery device or gastrointestinal lumen that are potentially being avoided (3).
