Estetrol – a new stage of combined hormonal contraception
The paper analyzes the modern literature data on estetrol, a native fetal estrogen that has been proposed as an estrogen component in the combined oral contraceptives, where only ethynyl estradiol has been traditionally used. a number of preclinical and clinical trials have provided evidence that estetrol is an estrogen that has unique properties since it does not affect hepatic parameters and hemostasis, has an antiestrogen effect on breast tissue and in high doses demonstrates an antitumor effect in breast and prostate cancers. Due to the above properties, estetrol has become an estrogen that become potentially safe as a component of the combined oral contraceptive containing 15 mg of estetrol and 3 mg of drospirenon in one tablet to be used in the 24/4 regimen, which have been now completed and shown the high efficacy of the contraceptive agent, as well as due to the minimal side effects: a good patient compliance with its usage. All phases of clinical trials of the new combined hormonal contraceptive containing 15 mg of estetrol and 3 mg of drospirenone in one tablet to be used in the 24/4 regimen, which have now been completed and shown the high efficacy of the contraceptive agent, a high safety, as well as due to the minimal side effects: a good patient compliance with its usage. Phase III trials of the new combined hormonal contraceptive, which have now been completed and shown that the new agent esterette is already available for patients and physicians.Apolikhina I.A., Prilepskaya V.N., Gorbunova E.A., Mezhevitinova E.A., Bychkova A.E.
Conclusion: The new hormonal combined oral contraceptive with a fetal estrogen, estetrol in combination with drispirenone ensures effective contraception, predictable presentations of hemorrhage, and a favorable safety profile.
