It is the purpose of this paper to discuss selected aspects of placental drug transfer. Accessment in this area is important from several points of view. A discussion of the passage of pharmacologic agents between the pregnant female and her fetus brings forth the great inadequacy of our present knowledge in this area, particularly with regard to quantitative kinetic data which would permit calculation of transfer rates.
