It has also been used - mostly off-label - for other indications, namely in the management of menorrhagia, fibrocystic breast disease, immune thrombocytopenic purpura, premenstrual syndrome, breast pain, and hereditary angioedema
Danazol is used to treat endometriosis
If danazol was initiated during exacerbation of angioedema resulting from trauma, stress, or other cause, periodically attempt to reduce dosage or withdraw therapy
Danazol suppresses oestrogen and progesterone receptors in the endometrium, leading to endometrial atrophy (thinning of the lining of the uterus) and reduced menstrual loss and to amenorrhoea in some women
DANAZOL (DA na zole) is used in women to treat endometriosis and the symptoms of fibrocystic breast disease
Danazol is a 17-ethinyl testosterone derivative that effectively suppresses endometriosis-related pain symptoms within 2 months of use
These findings suggest possible new mechanisms of action for danazol in the treatment of endometriosis and infertility associated with immune abnormalities
The amenorrheic state induced by danazol was characterized by normal basal levels of gonadotropins, prolactin, and estrogen
1980 May;33(5):550-6
Suppresses pituitary output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), resulting in regression and atrophy of normal and Danazol suppresses the pituitary-ovarian axis
The medication is usually used for 3 to 6 months
The only other demonstrable hormonal effect is weak androgenic activity
This suppression is probably a combination of depressed hypothalamic-pituitary response to lowered estrogen production, the alteration of sex steroid metabolism, and interaction of danazol with sex hormone receptors
Chemically, danazol is 17α-Pregna-2,4-dien-20-yno [2,3-d] isoxazol-17-ol
Danazol suppresses the ovulatory luteinising surge, interferes with gonadal steroidogenesis (directly and indirectly) and dampens the gonadotrophin response to luteinising hormone
Danol also depresses the preovulatory surge in output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), thereby reducing ovarian estrogen production
, 1990) and, coherently with this mechanism, danazol administration to women with endometriosis results in a decrease in serum IL-6 and IL-1α levels (Koumantakis et al
Danazol
This suppression is probably a combination of depressed hypothalamic-pituitary response to lowered estrogen production, the alteration of sex steroid metabolism, and interaction of danazol with sex hormone receptors
Danogen also depresses the preovulatory surge in output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), thereby reducing ovarian estrogen production
The only other demonstrable hormonal effect is weak androgenic activity
Danazol is a synthetic attenuated androgen that can interfere with normal interactions between the pituitary-hypothalamic axis and the gonads
LH와 FSH의 상승을 저해하지만, 정상여성에서 LH와 FSH의 기저 농도를 Danazol is a synthetic steroid, derivative of 17 alpha-ethinyl testosterone
The only other demonstrable hormonal effect is weak androgenic activity
Danazol is approved for use
The response rate is limited to approximately 45%, and results may require 6-10 months of therapy
Several randomized controlled trials (RCTs) demonstrated the efficacy of danazol in treating endometriosis-related pain
Lupron was approved by the Food and Drug As a gonadotropin inhibitor, danazol suppresses the pituitary-ovarian axis possibly by inhibiting the output of pituitary gonadotropins
As a gonadotropin inhibitor, danazol suppresses the pituitary-ovarian axis possibly by inhibiting the output of pituitary gonadotropins
unusual tiredness or weakness
Danazol Indications
A derivative of 17 alpha-etynyl testosterone, danazol suppresses pituitary gonadotropin secretion with subsequent inhibition of ovarian steroids
Cyclomen also depresses the preovulatory surge in output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), thereby reducing ovarian estrogen production
Danazol acts as an anterior pituitary suppressant by inhibiting the pituitary output of gonadotropins
Danazol suppresses the pituitary-ovarian axis
This suppression is probably a combination of depressed hypothalamic-pituitary response to lowered estrogen
Danazol suppresses the pituitary-ovarian axis
These studies demonstrate that: (1) danazol prevents the midcycle surge of luteinizing hormone (LH) and follicle-stimulating hormone (FSH); (2) danazol does not
Mechanism of action Use of danazol therapy in IMHA is based upon the following reported actions of the drug

It has a weak dose-related androgenic activity
Danol may also directly inhibits
The only other demonstrable hormonal effect is weak androgenic activity
Danazol also depresses the preovulatory surge in output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), thereby reducing ovarian estrogen production
As a gonadotropin inhibitor, danazol suppresses the pituitary-ovarian axis possibly by inhibiting the output of pituitary gonadotropins
Clinically, the action of danazol has been demonstrated by human pharmacological studies and clinical trials
Benzol may also directly inhibits Danazol at a concentration of 10(-6) M significantly suppressed IL-1 beta and TNF production in the presence of E2 and/or P at concentrations giving peak responses of IL-1 beta production
This could lead to life-threatening bleeding in the belly area
ANARGIL also depresses the preovulatory surge in output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), thereby reducing ovarian estrogen production
- does not significiantly lower or suppress basal LH or FSH levels in normal women
Danazol also depresses the preovulatory surge in output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), thereby reducing ovarian estrogen production
