Mechanism of
Action |
|
Estrogens exert their primary effects on the interphase DNA-protein complex
(chromatin) by binding to a receptor (usually located in the cytoplasm of a
target cell) and initiating translocation of the hormone-receptor complex to the
nucleus |
|
|
Pharmacodynamics/Kinetics |
|
90% of injected dose leaves bloodstream within 24 hours
Passive storage in reticuloendothelial system
Increasing the dose prolongs duration of action |
