Danamet100 mg

Danamet 100 mg is indicated for the following treatment- Endometriosis Benign breast disease Menorrhagia Gynecomastia Preoperative thinning of the endometrium before hysteroscopic endometrial ablation.

Drugs affecting (inhibiting) gonadotrophin

As a gonadotropin inhibitor, Danamet 100 mg suppresses the pituitary-ovarian axis possibly by inhibiting the output of pituitary gonadotropins. Danamet 100 mg also depresses the preovulatory surge in output of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), thereby reducing ovarian estrogen production. Danamet 100 mg may also directly inhibits ovarian steroidogenesis; bind to androgen, progesterone, and glucocorticoid receptors; bind to sex-hormone-binding globulin and corticosteroid-binding globulin; and increases the metabolic clearance rate of progesterone. Another mechanism of action by which Danamet 100 mg may use to facilitate regression of endometriosis is by decreasing IgG, IgM, and IgA concentrations, as well as phospholipid and IgG isotope autoantibodies. In the treatment of endometriosis, as a consequence of suppression of ovarian function, Danamet 100 mg causes both normal and ectopic endometrial tissues to become inactive and atrophic. This leads to anovulation and associated amenorrhea. In fibrocystic breast disease, the exact mechanism of action of Danamet 100 mg is unknown, but may be related to suppressed estrogenic stimulation as a result of decreased ovarian production of estrogen. A direct effect on steroid receptor sites in breast tissue is also possible. This leads to a disappearance of nodularity, relief of pain and tenderness, and possibly changes in the menstrual pattern. In terms of hereditary angioedema, Danamet 100 mg corrects the underlying biochemical deficiency by increasing serum concentrations of the deficient C1 esterase inhibitor, resulting in increased serum concentrations of the C4 component of the complement system.

Preoperative thinning of the endometrium: Adult: 400-800 mg daily, in up to 4 divided doses for 3-6 week. Benign breast disorders: Adult: Initially, 100-400 mg daily in 2 divided doses adjusted according to response and continued for 3-6 month. Hereditary angioedema: Adult: Initially, 200 mg bid-tid reduced thereafter according to patient's response. Endometriosis: Adult: 200-800 mg daily in 2 divided doses adjusted according to response, for 3-6 month or if necessary, up to 9 month. Menorrhagia: Adult: 200 mg once daily. Review treatment 3 month later. Gynaecomastia: Adult: Male adolescents: Initially, 200 mg daily, may increase to 400 mg daily after 2 month if no response occurs; adult men: Initial: 400 mg daily in up to 4 divided doses. Usual treatment duration: 6 month. Child: Male adolescents: Initially, 200 mg daily increased to 400 mg after 2 month if no response occurs. Treatment usually up to 6 months.

Insulin: Patients taking Danamet 100 mg may show increased insulin resistance. The significance of this is not known but such patients should be carefully monitored. Estrogens and progestogens: Theoretically Danamet 100 mg may interact with exogenous estrogens and/or progestogens. It has been suggested that Danamet 100 mg acts by binding to estrogen, progesterone or androgen receptors at various levels in the hypothalamic pituitary-ovarian axis. Therefore, women of child bearing age should use effective, non hormonal methods of contraception. Anticonvulsant therapy: Danamet 100 mg may affect the plasma concentration of carbamazepin and possibly the patient's response to this agent and to phenytoin. A similar interaction is possible for phenobarbital. Antihypertensive therapy: Danamet 100 mg can oppose the action of antihypertensive agents, possibly through effects on fluid retention. Cyclosporine: Danamet 100 mg can increase the plasma concentration of cyclosporine. Migraine therapy: Danamet 100 mg itself may provoke migraine and it may possibly reduce the effectiveness of medication to prevent the condition.

Pregnancy and breast-feeding Impaired hepatic, renal, or cardiac function Porphyria Thromboembolic disease Androgen-dependent tumor Abnormal vaginal bleeding that has not been fully investigated. Hypersensitivity to Danamet 100 mg.

Oedema, weight gain, sweating, acne, hirsutism, flushing, oily skin or hair, deepening of the voice, clitoral hypertrophy, amenorrhoea, hepatic dysfunction, CNS or GI disturbances, benign intracranial hypertension, reduction in breast size, visual disturbances, elevated LFT values.

Category X: Studies in animals or human beings have demonstrated fetal abnormalities or there is evidence of fetal risk based on human experience or both, and the risk of the use of the drug in pregnant women clearly outweighs any possible benefit. The drug is contraindicated in women who are or may become pregnant.

Epilepsy, migraine; cardiac, hepatic, renal disorders. Severe hypertension, diabetes, polycythaemia, history of thrombosis; children.

There have been no incidents of acute overdosage with Danamet 100 mg and it is unlikely that any immediate serious reaction will be seen from a single excessive dose. In case of the acute overdosage, the drug should be removed by gastric lavage and the patient should be kept under observation.

Store at 15-30°C.
