From the FDA Drug Label

Medroxyprogesterone acetate, administered parenterally in the recommended doses to women with adequate endogenous estrogen, transforms proliferative endometrium into secretory endometrium. Because of its prolonged action and the resulting difficulty in predicting the time of withdrawal bleeding following injection, medroxyprogesterone acetate is not recommended in secondary amenorrhea or dysfunctional uterine bleeding. In these conditions oral therapy is recommended.

The treatment for Hiperplasia endometrial using progestin can be administered orally.

  • The drug label mentions that in certain conditions, such as secondary amenorrhea or dysfunctional uterine bleeding, oral therapy is recommended 1.
  • This suggests that oral administration of progestin can be used for treating endometrial hyperplasia.

From the Research

El tratamiento con progestina para la hiperplasia endometrial debe ser administrado mediante un sistema intrauterino de levonorgestrel (LNG-IUS) en lugar de la administración oral, debido a su mayor eficacia y menor cantidad de efectos secundarios. La hiperplasia endometrial es un trastorno caracterizado por el crecimiento excesivo del revestimiento uterino, y el tratamiento con progestinas es una opción común para evitar la progresión a cáncer de endometrio. Según un estudio publicado en [@\5@], el LNG-IUS mostró una mayor probabilidad de regresión completa de la hiperplasia endometrial en comparación con otros tratamientos, incluyendo la administración oral de medroxyprogesterona acetato (MPA) y noretisterona (NET). Además, el estudio encontró que la combinación de MPA con metformina puede tener un efecto aún mayor.

Algunos de los beneficios del LNG-IUS incluyen:

  • Mayor eficacia en la regresión de la hiperplasia endometrial
  • Menor cantidad de efectos secundarios en comparación con la administración oral
  • Mayor tolerabilidad y satisfacción del paciente
  • Posibilidad de preservar la fertilidad en mujeres jóvenes

Sin embargo, es importante tener en cuenta que la elección del tratamiento debe basarse en la evaluación individual de cada paciente, considerando factores como la gravedad de la hiperplasia, la edad y la salud general del paciente, así como sus preferencias y necesidades personales. Como se menciona en [@\1@], la administración oral de progestinas puede ser una opción viable para algunas pacientes, pero es importante evaluar los beneficios y riesgos potenciales de cada tratamiento y discutirlos con el paciente antes de tomar una decisión.

En resumen, el tratamiento con progestina para la hiperplasia endometrial debe ser administrado mediante un sistema intrauterino de levonorgestrel (LNG-IUS) debido a su mayor eficacia y menor cantidad de efectos secundarios, aunque la elección del tratamiento debe basarse en la evaluación individual de cada paciente.
