Introduction To Perinatal Pharma Flashcards
Factors affecting drug pharmacokinetics in pregnancy
Lipid solubility Size and pH Placental transporters Protein binding Placental and drug metabolism
Factors that affect drug absorption in infants and children
Blood flow at the site of admin
Gastrointestinal function
Increased oral absorption
Ampicilin and Pen G
The concentrations achieved in breastmilk are high enough so that signs of pyridoxine deficiency may occur in the infant if the mother is not given pyridoxine supplements
