Cipgest
Cipgest Uses, Dosage, Side Effects, Food Interaction and all others data.
Cipgest is a nortestosterone derivative with no androgenic but rather an antiandrogenic activity of approximately 1/3 of that of cyproterone acetate. Cipgest binds to the progesterone receptor of the human uterus with only 10% of the relative affinity of progesterone. Despite its low affinity to the progesterone receptor, dienogest has a strong progestogenic effect in vivo. Cipgest has no significant androgenic, mineralocorticoid or glucocorticoid activity in vivo.
Cipgest acts on endometriosis by reducing the endogenous production of estradiol and thereby suppressing the trophic effects of estradiol on both the eutopic and ectopic endometrium. When given continuously, dienogest leads to a hypoestrogenic, hypergestagenic endocrine environment causing initial decidualization of endometrial tissue followed by atrophy of endometriotic lesions. Additional properties eg, immunologic and antiangiogenic effects, seem to contribute to the inhibitory action of dienogest on cell proliferation.
Cipgest exhibits a very potent progestagenic effect in the endometrium, and causes endometrial atrophy after prolonged use . It also mediates an antiandrogenic effect that is equivalent to approximately one third that of cyproterone acetate . A dose of 2 mg inhibits the growth of ovarian follicles at 10 mm and maintains the concentration of progesterone at a low level, but has a weak inhibitory effect on FSH and LH. 1mg/kg of dienogest also directly inhibits ovulation . In clinical trials composing of patients with endometriosis, dienogest therapy effectively reduced painful symptoms and endometriotic lesions associated with the disorder .Cipgest displays no antiestrogenic activity as it activate neither estrogen receptor (ER) α nor ERβ [A16570], and causes hypoestrogenic effects instead as it is shown to decrease the relative expressions of ERβ and ERα . It has no glucocorticoid or mineralocorticoid effects. In combined oral contraceptive pills (COCP) with ethinyloestradiol, dienogest conjuction therapy effectively reduces the symptoms of acne and hirsutism, as well as improving excessively heavy or prolonged menstrual bleeding .

Cipgest is also used to associated treatment for these conditions: Hypermenorrhea, Pain, Contraception, Oral Contraceptives
How Cipgest works
Cipgest acts as an agonist at the progesterone receptor (PR) with weak affinity that is comparable to that of progesterone but has a very potent progestagenic effect in the endometrium, causing endometrial atrophy after prolonged use . It promotes antiproliferative, immunologic and antiangiogenic effects on endometrial tissue. Cipgest reduces the level of endogenous production of oestradiol and thereby suppressing the trophic effects of oestradiol on both the eutopic and ectopic endometrium . Continous administration of dienogest results in hyperprogestogenic and moderately hypoestrogenic endocrine environment, which causes initial decidualization of endometrial tissue . It is an antagonist at androgen receptors, improve androgenic symptoms such as acne and hirsutism [A16570].
Dosage
Cipgest dosage
Tablet-taking can be started on any day of the menstrual cycle.
The dosage of Cipgest is 2 mg daily without any break, taken preferably at the same time each day with some liquid as needed. Tablet must be taken continuously without regard to vaginal bleeding. When a pack is finished, the next one should be started without interruption.
In the event of missed tablet(s), the woman should take 2 mg only, as soon as she remembers, and should then continue the next day to take the tablet at her usual time. A tablet not absorbed due to vomiting or diarrhea should likewise be replaced by 2 mg.
Side Effects
Increased weight; depressed mood, sleep disorder, nervousness, loss of libido, altered mood; headache, migraine; nausea, abdominal pain or distension, flatulence, vomiting; acne; alopecia; back pain; breast discomfort, ovarian cyst, hot flush, uterine/vaginal bleeding including spotting; asthenic conditions, irritability.
Toxicity
Oral LD50 in mouse is 4 mg/kg . In a long-term carcinogenicity study involving rats and mice, exposure of 10 times the dose of maximum recommended clinical dose of dienogest resulted in increased incidences of pituitary adenomas, fibroepithelial mammary tumours, stromal polyps of the uterus and malignant lymphoma . These tumors are thought to arise from marked species differences in the optimal oestrogen:progestogen ratio for reproductive function. In rat liver foci assay, dienogest did not induce tumor promotion activity . Cipgest does not display genotoxic potential.
Precaution
Before starting Cipgest treatment, pregnancy must be excluded. During treatment, patients are advised to use nonhormonal methods of contraception (e.g, barrier method) if contraception is required.
As Cipgest is a progestogen-only preparation, it can be assumed that special warnings and special precautions for use of other progestogen-only preparations are also valid for the use of Cipgest .
Changes in Bleeding Pattern: Cipgest treatment affects the menstrual bleeding pattern in the majority of women.
Hepatic Impairment: Cipgest is contraindicated in patients with present or past severe hepatic disease.
Impairment of Fertility: Based on available data, ovulation is inhibited in the majority of patients during treatment with Cipgest. However, Cipgest is not a contraceptive.
If contraception is required, a nonhormonal method should be used.
Interaction
Progestogens including Cipgest are metabolized mainly by the cytochrome P450 3A4 system . Therefore, inducers or inhibitors of CYP3A4 may affect the progestogen drug metabolism. Known CYP3A4 inhibitors like azole antifungals (e.g, ketoconazole, itraconazole, fluconazole), cimetidine, verapamil, macrolides (e.g, erythromycin, clarithromycin and roxithromycin), diltiazem, protease inhibitors (e.g, ritonavir, saquinavir, indinavir, nelfinavir), antidepressants (e.g, nefazodone, fluvoxamine, fluoxetine) may increase plasma levels of progestogens and result in adverse reactions.
Food Interaction
- Avoid grapefruit products. Grapefruit inhibits the CYP3A metabolism of dienogest, which may increase its serum concentration.
- Avoid St. John's Wort. This herb induces the CYP3A metabolism of dienogest and may reduce its serum concentration.
- Take at the same time every day.
Volume of Distribution
The apparent volume of distribution (Vd/F) of dienogest is 40 L .
Elimination Route
Cipgest is rapidly absorbed following oral administration, with 91% bioavailability. The peak plasma concentration of 47 ng/mL is reached at about 1.5 hours after single ingestion of 2 mg . The stable concentrations of the drug are reached after two days of initial treatment .
Half Life
Elimination half-life of dienogest is around 9-10 hours. The half-life of urinary metabolites excretion is 14 hours .
Clearance
The metabolic clearance rate from serum (Cl/F) is 64 mL/min .
Elimination Route
The ratio of renal elimination to fecal elimination of dienogest is 3:1, where dienogest is predominantly excreted in the form of inactive metabolites. Most of orally administered drug is excreted in the urine within the first 24 hours of ingestion .
Pregnancy & Breastfeeding use
Use in Pregnancy: There are limited data from the use of Cipgest in pregnant women. Animal studies and data from women exposed to Cipgest during pregnancy reveal no special risks on pregnancy, embryonic/fetal development, birth or development after birth for humans. However, Cipgest should not be administered to pregnant women because there is no need to treat endometriosis during pregnancy.
Use in Lactation: Treatment with Cipgest during lactation is not recommended. Physiochemical properties and animal data indicate excretion of Cipgest in breast milk. A decision must be made whether to discontinue breastfeeding or to abstain from Cipgest therapy taking into account the benefit of breastfeeding for the child and the benefit of therapy for the woman.
Contraindication
Hypersensitivity to dienogest or to any of the excipients of Cipgest. Cipgest should not be used in the presence of any of the conditions such as, Active venous thromboembolic disorder; arterial and cardiovascular disease, (e.g, myocardial infarction, cerebrovascular accident, ischemic heart disease); diabetes mellitus with vascular involvement; presence or history of severe hepatic disease as long as liver function values have not returned to normal; presence or history of liver tumors (benign or malignant); known or suspected sex hormone-dependent malignancies and undiagnosed vaginal bleeding.
Special Warning
Use in Children: Cipgest is not indicated in children prior to menarche. The safety and efficacy of Cipgest in adolescents (menarche to 18 years) has not yet been established.
Use in the Elderly: There is no relevant indication for the use of Cipgest in the geriatric population.
Acute Overdose
Acute toxicity studies performed with Cipgest did not indicate a risk of acute adverse effects in case of inadvertent intake of a multiple of the daily therapeutic dose. There is no specific antidote. Cipgest 20-30 mg/day (10-15 times higher dose than in Dinogest) over 24 weeks of use were very well tolerated.
Storage Condition
Keep in a cool and dry place. Protect from light. Keep out of the reach of children.
