About this ingredient

Danazol is a synthetic steroid derived from ethisterone, primarily used in the management of endometriosis and fibrocystic breast disease. It functions by suppressing the pituitary-ovarian axis, leading to decreased estrogen production and a subsequent reduction in the growth of endometrial tissue. This mechanism makes it effective in alleviating the symptoms associated with these conditions.

In addition to its gynecological applications, Danazol is also utilized in the treatment of hereditary angioedema, a condition characterized by recurrent episodes of severe swelling. By increasing the levels of C1 inhibitor and other proteins in the blood, Danazol helps prevent these episodes, providing significant relief to patients.

Danazol's pharmacokinetics reveal that it is well-absorbed orally, with peak plasma concentrations typically reached within 2 to 8 hours post-administration. It is extensively metabolized in the liver, and its metabolites are excreted primarily via the urine. Due to its hepatic metabolism, caution is advised in patients with liver impairment.

Common side effects of Danazol include weight gain, acne, and changes in menstrual flow, which are attributed to its androgenic properties. It is contraindicated in pregnancy due to potential teratogenic effects, and women of childbearing age should use effective contraception during treatment. Regular monitoring of liver function and lipid profiles is recommended during prolonged therapy.

Danazol's role in compounded formulations allows for tailored dosing regimens, optimizing therapeutic outcomes while minimizing adverse effects. This customization is particularly beneficial for patients with unique clinical needs or those who experience side effects with standard dosages. As a versatile API, Danazol continues to be a valuable option in the therapeutic arsenal for managing specific hormonal and immunological disorders.
