VIII. Drug Passage into Breast Milk
•Diffusion from maternal plasma into milk
•Higher maternal plasma levels mean higher breast milk concentrations
•Equilibrium will be established with most drugs between milk and plasma
IX. Drug Transfer
•Across Placenta
–Molecular weight
–Lipid solubility
–Ionization
–Protein binding
–Chemical Structure
•Into Breast Milk
–Molecular weight
–Lipid solubility
–Ionization
–Protein binding
–Drug concentration
–Drug equilibrium
X.Other Factors
•Across Placenta
–Size < 400 daltons
–High blood concentration
–Similar configuration
•Into Breast Milk
–Size < 200 daltons
–Drug pKa
–Equilibration speed
–High blood concentration
XI. Fetal Drug Disposition
• 60 – 80% passes through liver, the rest travels through ductus venosus to heart and brain
