Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for a human product; Pregnant women must take care of the potential risks.
Category D: There is adequate data with sufficient evidence of human fetal risk from various platforms. However, despite potential dangers may be used only in emergencies for potential benefits.
Category X: Drugs listed in this category outweigh the risks over benefits. The drug is not for pregnant women.
Category N: No data is available for the drug under this category.

Pharmacology

Pharmacology:

dienogest is a synthetic progestin, which means it has similar effects to the natural hormone progesterone. As a progestin, dienogest has a variety of pharmacological effects on the body:

Progestational activity: dienogest binds to and activates progesterone receptors in the body, leading to changes in the endometrium and inhibition of ovulation.
Anti-androgenic activity: dienogest has anti-androgenic effects, meaning it reduces the activity of androgens (male hormones) in the body. This makes it useful for treating androgen-related conditions, such as acne and hirsutism.
Anti-inflammatory activity: dienogest has anti-inflammatory effects, which may be useful in the treatment of conditions such as endometriosis, where inflammation is thought to play a role.
Inhibition of GnRH secretion: dienogest reduces the secretion of GnRH from the hypothalamus, leading to decreased levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) and suppression of ovulation.
Thinning of endometrial lining: dienogest may cause thinning of the endometrial lining, making it less receptive to implantation by a fertilized egg.

Pharmacodynamics:

Some of the pharmacodynamics of dienogest are:

Inhibition of ovulation: dienogest inhibits ovulation by suppressing the secretion of LH and FSH, which are responsible for triggering ovulation. This effect is transferred by the negative feedback on the hypothalamic-pituitary-ovarian (HPO) axis.
Changes in the endometrium: dienogest causes changes in the endometrium that make it less receptive to implantation by a fertilized egg. It reduces the proliferation of the endometrium and causes it to become thinner and less vascularized, which reduces the chances of implantation.
Anti-androgenic activity: dienogest has anti-androgenic effects that make it useful in the treatment of androgen-related conditions, such as acne and hirsutism. It competes with androgens for binding to the androgen receptor and reduces the activity of androgens in the body.
Anti-inflammatory activity: dienogest has been shown to have anti-inflammatory effects that may be useful in the treatment of conditions such as endometriosis, where inflammation is thought to play a role. It reduces the expression of pro-inflammatory cytokines and chemokines and decreases the infiltration of immune cells into the affected tissues.
Modulation of cervical mucus: dienogest thickens the cervical mucus, blocking the entry of sperm into uterus.
Feedback on the hypothalamic-pituitary-adrenal (HPA) axis: dienogest has been shown to modulate the activity of the HPA axis by reducing the secretion of corticotropin-releasing hormone (CRH), which is responsible for the activation of the stress response.

Pharmacokinetics:

Absorption

dienogest is rapidly absorbed after oral administration, with peak plasma concentrations reached within 1-2 hours. The absolute bioavailability of dienogest is approximately 90%, and it is not affected by food intake.

Distribution

dienogest is highly bound to plasma proteins (over 95%), mainly to sex hormone-binding globulin (SHBG) and albumin. The volume of distribution of dienogest is approximately 4 L/kg.

Metabolism

dienogest is extensively metabolized in the liver by cytochrome P450 enzymes, primarily CYP3A4. The main metabolite is 3-ketodesogestrel, which has a similar pharmacological activity to dienogest. Other metabolites include hydroxylated and conjugated metabolites.

Elimination and Excretion

The elimination half-life of dienogest is approximately 9-11 hours. It is primarily eliminated in the feces (42%) and urine (27%) as metabolites, with less than 1% excreted unchanged.

Adminstartion

Administration:

dienogest is primarily administered orally in the form of tablets. It is available as a standalone medication or in combination with estrogen in oral contraceptive pills.

The dosage of dienogest may vary depending on the condition being treated. It is taken as an oral tablet daily. The effect decreases with St John’s Wort and increases with grapefruit juice.

Why do we use dienogest?

dienogest is used for a variety of indications, mainly related to its ability to modulate the hormonal environment of the body. Some of the uses of dienogest are:

Contraception: dienogest is used as a component of combined hormonal contraceptives (CHCs), which also contain an estrogen component. These contraceptives work by suppressing ovulation, thickening cervical mucus, and altering the endometrium, making it less receptive to implantation. dienogest is a highly effective contraceptive, with a failure rate of less than 1% when used correctly.
Endometriosis: dienogest is used in the treatment of endometriosis, a condition where the endometrial tissue grows outside the uterus and causes pain and inflammation. dienogest works by suppressing the growth and proliferation of endometrial tissue, reducing pain and other symptoms associated with endometriosis.
Dysmenorrhea: dienogest is also used in the treatment of dysmenorrhea, which is severe menstrual pain. It reduces pain by suppressing the growth and proliferation of endometrial tissue, which is responsible for the pain associated with dysmenorrhea.
Acne: dienogest has anti-androgenic properties, which make it useful in the treatment of acne, a condition that is often related to excess androgen activity. By reducing androgen activity, dienogest can help to reduce sebum production and inflammation, which are major factors in the development of acne.
Hirsutism: dienogest is also used in the treatment of hirsutism, a condition characterized by excessive hair growth in women, often associated with excess androgen activity. By reducing androgen activity, dienogest can help to reduce the growth of unwanted hair.
