Danocrine

Danocrine is the brand name for the medication danazol. It's a synthetic steroid derived from ethisterone, and it has a variety of biological effects. It's primarily used to treat certain medical conditions, particularly those affected by hormonal imbalances.

What is Danocrine (Danazol)?

Danocrine, or danazol, is a synthetic androgen, meaning it has weak male hormone-like properties. It works by suppressing the production of hormones from the pituitary gland, specifically follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This suppression leads to a decrease in the body's production of estrogen and progesterone, creating a state of hypoestrogenism (low estrogen).

Danazol is used to treat:

• Endometriosis: A condition where tissue similar to the lining of the uterus grows outside the uterus, causing pain and other symptoms. Danazol helps to shrink and inactivate these endometrial tissues.

• Fibrocystic Breast Disease: A benign condition characterized by painful, lumpy breasts. Danazol helps to reduce breast pain and nodularity.

• Hereditary Angioedema (HAE): A rare genetic disorder that causes episodes of severe swelling in various parts of the body. Danazol helps to increase the levels of a protein (C1-esterase inhibitor) that is deficient in people with HAE, thus preventing attacks.

Side Effects and Benefits

Benefits:

• Pain Relief: Effective in reducing pain associated with endometriosis and fibrocystic breast disease.

• Symptom Management: Can help to resolve physical symptoms like breast lumps and swelling attacks in HAE.

• Amenorrhea: In women with endometriosis, it often induces amenorrhea (the absence of menstrual periods), which can provide significant relief from painful periods.

Side Effects:

Because danazol has androgenic effects, it can cause masculinizing side effects, particularly in women.

• Common Side Effects:

  • Weight gain

  • Acne and oily skin/hair

  • Flushing and sweating

  • Deepening of the voice

  • Unusual hair growth (hirsutism)

  • Irregular menstrual periods or absence of periods (amenorrhea)

  • Decreased breast size

  • Vaginal dryness or irritation

  • Mood changes, nervousness

• Serious Side Effects:

  • Liver problems: Long-term use can lead to serious liver issues, including peliosis hepatitis and benign hepatic adenoma.

  • Blood clots: Increased risk of blood clots, which can lead to stroke or other life-threatening events.

  • Increased intracranial pressure: Can cause severe headaches and vision problems.

  • High cholesterol: Can cause an increase in cholesterol levels.

Pros and Cons

Pros:

• Effective in treating its approved conditions.

• Can provide significant symptom relief and improve quality of life for people with endometriosis, fibrocystic breast disease, and HAE.

• Generic versions are available, which may make it more affordable.

Cons:

• Significant side effects: The androgenic side effects can be difficult to tolerate, especially for women.

• Not a cure: It manages symptoms but does not cure the underlying condition.

• Contraindications: It cannot be used during pregnancy, and women of childbearing age must use a non-hormonal form of birth control while on the medication. It can cause birth defects.

• Requires close medical monitoring, especially for liver function and cholesterol levels.

Dosage and Frequency

The dosage of danazol varies depending on the condition being treated and the patient's response. It is typically taken in two divided doses per day.

• For Endometriosis:

  • Mild cases: 200 to 400 mg per day.

  • Moderate to severe cases: 800 mg per day.

  • Treatment usually lasts for 3 to 9 months.

• For Fibrocystic Breast Disease:

  • 100 to 400 mg per day.

  • Treatment usually lasts for 2 to 6 months.

• For Hereditary Angioedema:

  • Initial dose is usually 200 mg, two or three times a day.

  • The dose is then gradually decreased to the lowest effective dose to prevent attacks.

Half-Life and Detection Time

• Half-life: The elimination half-life of danazol is approximately 24 hours. The half-life can vary with acute (3–10 hours) and chronic (24–26 hours) use.

• Detection time: Danazol and its metabolites can be detected in drug tests for an extended period after use, but the exact detection window can vary based on individual metabolism, dosage, and testing method. It can be detectable for weeks to months, especially in hair analysis.

Sterogenic, Progestronic, Prolactin Effects

• Sterogenic: Danazol is a synthetic steroid derived from ethisterone.

• Progestronic: Danazol does not have significant progestational activity. However, it can bind to progesterone receptors, acting as an agonist.

• Prolactin: Danazol can cause a decrease in serum and pituitary prolactin levels. This effect may contribute to its efficacy in treating conditions like fibrocystic breast disease.

Anabolic-Androgenic Ratio

The anabolic-androgenic ratio is a way to compare the anabolic (muscle-building) effects of a substance to its androgenic (masculinizing) effects. This ratio is typically expressed as a number relative to testosterone, which has a ratio of 100:100.

Danazol does not have a commonly cited anabolic-androgenic ratio. While it has some anabolic properties, its androgenic effects are weak compared to pure anabolic steroids. The primary use of danazol is for its hormonal suppression, not its anabolic effects, and it's not typically used for performance enhancement. Due to its significant side effects and the fact that its androgenic properties are considered a negative side effect rather than a desired one, it's not categorized in the same way as common anabolic-androgenic steroids.
