Dienogest

Dienogest

Dienogest is an approved medication used for the treatment of endometriosis and other gynecological conditions. It belongs to a group of medicines known as progestogens and works by causing changes in the uterus and other parts of the body. It is available as tablets and as an injection.

Uses For

Dienogest is most commonly used in the treatment of endometriosis, a disorder in which the tissue that normally lines the inside of the uterus grows on the outside of the uterus or on other organs in the body. It is also used to treat dysmenorrhea, irregular or heavy menstrual periods, and ovarian cysts.

Mechanism Of Action

Dienogest works by influencing the hormone levels in the body. It binds to progesterone receptors and blocks the action of progesterone. This causes changes in the uterus and other parts of the body, resulting in lowered levels of certain hormones. It also inhibits the growth of endometriotic tissue and helps reduce inflammation.

How Long Does it Take to Work?

The effects of Dienogest usually become evident within a few weeks. However, it may take up to a few months for the full effects to be seen. It is important to take the medication as prescribed and to continue with it until the end of the course.

Absorption

Dienogest is well absorbed after oral administration with an absolute bioavailability of approximately 80%. Peak concentrations of the drug are reached within 1 to 2 hours after administration.

Route Of Elimination

Dienogest is mainly eliminated through the liver. After ingestion, only a small fraction of the drug is excreted unchanged in the urine. The rest is metabolized to inactive metabolites which are then eliminated through the bile and feces.

Dosage

Tablet-taking can be started on any day of the menstrual cycle. The dosage of Dienogest is 2 mg daily without any break, taken preferably at the same time each day with some liquid as needed. Tablet must be taken continuously without regard to vaginal bleeding. When a pack is finished, the next one should be started without interruption.

In the event of missed tablet(s), the woman should take 2 mg only, as soon as she remembers, and should then continue the next day to take the tablet at her usual time. A tablet not absorbed due to vomiting or diarrhea should likewise be replaced by 2 mg.
