Abstract
The pharmacokinetic considerations that are unique to the intrauterine (IU) route of macromolecule administration are discussed, and specific examples of macromolecules with high (insulin) and low (dextran 70 000 and polyethylene glycol 4000) absorption rates, following IU administration in rats are addressed. The pharmacodynamic aspects of IU administration are also discussed with specific focus on the differences between the continuous mode of peptide administration in contrast to the pulsatile mode and on counter-regulation by feedback mechanisms in the body. These issues are demonstrated by specific examples of the kinetics of action of calcitonin, erythropoietin and insulin following IU administration in rats.
