Pharmacokinetics:
Androkur, 10 mg
After oral administration of cyproterone acetate is completely absorbed in a wide dose range. Cmax in serum after intake of 10 mg is approximately 1.5 hours and is about 75 ng/ml Total Cl — 3.6 ml/min/kg Metabolized by various pathways including hydroxylation and conjugation. The main metabolite is 15&beta-hydroxy derivative.
A certain amount of the dose excreted unchanged in the bile. Most of the dose is excreted as metabolites in urine and bile in the ratio of 3:7, T1/2 is 1.9 days. The rate of elimination of metabolites from the plasma has a similar value of (T1/2 — 1.7 days).
Cyproterone acetate is almost exclusively bound to plasma albumin. In the free state is about 3.5–4%. Since the link with proteins is nonspecific, changes in the concentration of globulin, linking sex hormones do not affect the pharmacokinetics of cyproterone acetate.
Due to the long duration of excretion in the final phase of elimination from plasma, as well as daily use, probably increasing the concentration of cyproterone in the serum in 2-2,5 times for one cycle of treatment.
The absolute bioavailability of cyproterone acetate is almost complete.
Androkur, 50 mg
Cyproterone acetate is completely absorbed after ingestion. It binds almost exclusively to albumin in plasma. In the free state is about 3.5–4 %. Since the link with proteins is nonspecific, changes in the concentration of globulin, linking sex hormones do not affect the pharmacokinetics of cyproterone acetate.
T1/2 — (43,9±12,8) h. Total clearance of cyproterone acetate from serum — (3,5±1,5) ml/min/kg. biotransformation in the liver and excreted mainly as metabolites in the bile and urine at a ratio of 3:7, part is excreted unchanged in the bile.
The absolute bioavailability of cyproterone acetate is almost complete (about 88%).
Androkur, 100 mg
The drug is completely absorbed after oral administration. Cmax of the drug in plasma is reached after an average of (2,8±1,1) h. protein Binding (mostly to albumin) serum — about 96%.
T1/2 — (42,8±9,7) h. Total clearance of cyproterone acetate from serum — (3,8±2,2) ml/min/kg. biotransformation in the liver and excreted mainly as metabolites in the bile and urine at a ratio of 3:7, part is excreted unchanged in the bile.
Androkur Depot
After the/m introduction cyproterone acetate slowly and fully released. Cmax = (180±54) ng/ml is achieved in 2-3 days. Then, a decrease in the drug concentration in the plasma with T1/2 — (4±1,1) of the day. Equilibrium concentration achieved in 5 weeks. Cyproterone acetate is almost completely bound to albumin in plasma. Only 3.5–4% are in the blood in a free form. Since the bond with plasma proteins is non-specific, changes in the level of globulin that binds sex hormones do not affect the pharmacokinetics of cyproterone acetate.
Most of the displays in the form of metabolites with urine and faeces, small quantities — in the bile in unchanged form.
Description pharmacological action:
Androkur, 10 mg
The active ingredient Androcur 10 mg reduces the influence of male sex hormones (androgens), which also produced in the female body. Therefore, women Androkur 10 mg eliminates the pathological changes which are caused by increased formation of androgens or an increased sensitivity to them: strong hair on the face and other body parts, as well as acne and seborrhea, which are largely dependent on androgens enhanced the function of the sebaceous glands.
Androkur, 50 and 100 mg
Androkur Depot
Cyproterone acetate is a competing mechanism of action inhibits the action of androgens at their target organs, and has a Central antigonadotropnym action, leading to a decrease of testosterone synthesis in the testes and its content in the blood serum. This results in inhibition of androgen stimulation of the prostate tissue. In men, the use of cyproterone acetate observed inhibition of libido, potency and testicular function. These effects are completely reversible and disappear after cessation of treatment.

To indicate specific adverse reactions is the most appropriate term from MedDRA — medical dictionary for regulatory activities (version 8.0). Synonyms or similar state not be listed, but these should also be taken into account. In men with treatment Androkurom reduced libido and potency, moreover, suppressed the gonadal function. These changes are reversible and disappear after discontinuation of therapy.
Within a few weeks the result of the antiandrogenic and antigonadotropnym action Androcur is the suppression of spermatogenesis, which is gradually recovering several months after discontinuation of therapy. In men receiving Androcur can lead to the development of gynecomastia (which is sometimes accompanied by enhanced tactile sensitivity and nipple soreness), which usually takes place after drug withdrawal or dose reduction. As with other antiandrogen drugs, Androkurom caused by prolonged deficiency of androgens can lead to the development of osteoporosis.
It was reported on the development of benign cerebral meningiomas in connection with long-term (several years) taking Androcur in the dose of 25 mg or more.

Drug interactions:
Androkur, 10 mg
May change the need for oral antidiabetic agents or insulin.
Androkur, 50 mg
Androkur Depot
Despite the lack of clinical studies interactions, it can be expected that ketoconazole, Itraconazole, clotrimazole, ritonavir and other strong inhibitors of CYP3A4 will inhibit the metabolism of cyproterone acetate, which is metabolized by CYP3A4. On the other hand, inducers of CYP3A4, such as rifampicin, phenytoin and products containing St. John's wort can reduce the concentration of cyproterone acetate.
Based on the results of in vitro studies, at high therapeutic doses of cyproterone acetate (100 mg 3 times per day) possible inhibition of isozymes of cytochrome P450, such as CYP2C8, 2C9, 2C19, 2D6 and ZA4.
Associated with statin use the risk of myopathy and rhabdomyolysis may be increased by concomitant administration of high therapeutic doses of cyproterone acetate with inhibitors of HMG-COA reductase inhibitors (statins), which are metabolized mainly by CYP3A4, as they have the same way of metabolism.
Patients with diabetes may change the need for oral antidiabetic agents or insulin.
Androkur, 100 mg
Antigonadotropnym action of cyproterone acetate is enhanced by its combined use with agonists of gonadotropin-releasing hormone. Under the action of cyproterone acetate reduced the initial increase in testosterone production caused by agonists of gonadotropin-releasing hormone.
Method of application and dose:
Androkur
Inside, after eating, squeezed small amounts of liquid.
Androkur, 10 mg
To provide adequate contraception and prevent intermenstrual bleeding accept Androkur in combination with the drug Diane-35.
The appointment of both preparations begin in the 1st day of the cycle (1st day of menstrual bleeding).
As a rule, in addition to Diane-35 daily take 1 table. Androcur at the same time from the 1st to the 15th day of the treatment cycle.
In the pack each tablet is marked with the day of the week on which it should be adopted. After administration 15 tab. within 15 days, in the remaining 6 days will only accept to Diana-35.
When 21 days of receiving a calendar pack of Diane-35 over, it should be a 7 day break from taking pills, during which should begin bleeding.
After a 7-day interval regardless of whether the bleeding stopped or still continues, the pills resume of the following calendar packs Androkur and Diane-35.
If during a break the bleeding has not occurred, which happens very rarely, you should stop the treatment and do not resume taking the pill until then, until will not be excluded pregnancy.
If a woman forgot to take the pill Diane-35 in normal times, it should be done no later than during the next 12 h. If the time of normal reception to Diana-35 has been more than 12 hours, contraceptive effect in this cycle may be impaired. You need to pay attention to the instructions regarding the contraceptive reliability, as well as recommendations on missed pills are included in information on the drug Diane-35. If, after this cycle of bleeding is missing, before resuming taking the pills should exclude pregnancy.
Skipping pills Androkur can lead to reduced therapeutic effect and cause intermenstrual bleeding. Missed pills Androkur leave not taken (i.e., should not take a double dose to compensate for the missed tablet) and resume taking the drug at the usual time with Diane-35.
Duration of treatment determines the physician depending on the severity of the pathological signs of androgenization and response to treatment. Usually the drugs must be taken for several months. The therapeutic effect in acne and seborrhea usually appears more quickly than hirsutism and alopecia.
After clinical improvement should try to continue treatment only in the drug Diane-35.
Androkur, 50 and 100 mg
For reduced libido in sexual deviations: as a rule, initial dose 1 table. (50 mg 2 times a day). If necessary, the dose can be increased to 200-300 mg/day (2 table. Androcur 50 mg 2-3 times a day) for a short period. Upon reaching a satisfactory result, you should try to reduce the dose to the minimum effective. In most cases it is enough to take 50 mg/day (1/2 tab. 2 times a day). When selecting a maintenance dose or if you cancel therapy, the dose should be reduced gradually.
With this purpose, the daily dose is recommended to reduce to 1 table. or better 0.5 table. within a few weeks.
To achieve sustainable therapeutic effect should be taken Androkur for a long time, if possible, while conducting psychotherapy.
Antiandrogen therapy of inoperable prostatic cancer: 200-300 mg/day (2 table. Androcur 50 mg or 1 table. Androcur 100 mg 2-3 times a day, for a long time).
With the improvement in or achievement of remission should not interrupt treatment or reduce dosage.
If signs of disease progression preparation Androkur, 100 mg should be discontinued.
To reduce the initial increase of androgens during therapy with agonists of gonadotropin-releasing hormone (GnRH): initially 200 mg per day (2 table. Androcur 50 mg or 1 table. Androcur 100 mg 2 times a day) as monotherapy for 5-7 days, then 200 mg daily for 3-4 weeks in combination with an agonist of GnRH in the manufacturer's recommended dosage.

In/m, slowly, deep into muscle.
Like all oily solutions Androkur Depot is administered only in/m! In rare cases during the injection or immediately after it may be short-term reactions (urge to cough, coughing fits, feeling of shortage of air). Very slow introduction of the drug allows to avoid such reactions. It is necessary to avoid intravascular injection.
Decreased sex drive in sexual deviations: the usual 300 mg (1 amp.) I/m every 10-14 days. In exceptional cases, when this dose is not enough you can enter 600 mg (2 amp.) every 10-14 days (preferably 3 ml in the right and left buttock). Upon reaching a satisfactory result of treatment should try to reduce the dose, gradually increasing the interval between injections.
To achieve sustainable therapeutic effect should be taken Androkur Depot for a long time, if possible, while conducting psychotherapy.
Antiandrogen therapy for inoperable carcinoma of the prostate: 300 mg/m every 7 days.
With the improvement in or achievement of remission should not interrupt treatment or reduce dosage.
Overdose:
Androkur, 10 mg
In studies of acute toxicity after a single dose of drug it was found that cyproterone acetate, the active ingredient of the preparation Androkur can be considered practically non-toxic substance. The risk of acute intoxication after a single accidental ingestion of multiple therapeutic doses is also unlikely. Overdose in case of single application of a large number of tablets Androcur 10 mg was not reported.
Symptoms (in case of accidental intake of a large dose of the drug): nausea, intermenstrual bleeding in women.
Treatment: symptomatic, no specific antidote.
Androkur, 50 and 100 mg
Androkur Depot
Studies of acute toxicity after a single application of the drug showed that cyproterone acetate can be considered practically non-toxic substance. Also a remote risk of acute intoxication after a single accidental dose several times the recommended therapeutic dose.
Special instructions:
Androkur, 10 mg
Before treatment should conduct a General medical and gynecological examination (including breast examination and a smear of cervical mucus). It is also necessary to exclude pregnancy.
Patients with diabetes may change the need for oral hypoglycemic agents or insulin. Patients with diabetes during treatment with Androkur drug should be under a doctor's supervision.
During treatment should use caution when doing activities that require increased attention.
During treatment requires periodic monitoring of liver function.
In rare cases, against the backdrop of sex steroids, which include cyproterone acetate, observed the development of liver tumors. Despite the fact that the connection with the supplementation has not been proven, in case of severe pain in the abdomen that do not disappear within a short time should immediately consult a doctor.
The drug Androkur is contraindicated in pregnancy. To prevent unwanted pregnancy, as well as intermenstrual bleeding should simultaneously apply the contraceptive drug Diane-35, which causes bleeding and due to the fact that it contains the same active substance antiandrogen (cyproterone acetate) enhances the therapeutic effect of the preparation Androkur.
If combination therapy during the 3-week period of taking the pills observed spotting, treatment should not be interrupted. However, persistent or recurrent late bleeding, you must contact your doctor for a gynaecological examination.
Because of the need for additional intake of Diane-35 should also take into account all the relevant information for this drug.
Caution — diabetes.
Androkur, 50 mg, Androkur Depot
Androkurom treatment is not recommended until the completion of puberty, because we can not exclude the likelihood of an adverse impact on growth and on more nestabilizirovannoy the endocrine system.
During treatment Androkurom should regularly assess liver function, adrenal and examination of peripheral blood. In patients receiving daily 200-300 mg cyproterone acetate have also been cases of hepatotoxicity, including jaundice, hepatitis and hepatic failure, sometimes fatal. The majority of these cases were registered in men with carcinoma of the prostate.
Toxicity is dose-dependent and usually develops several months after the start of therapy. Before the beginning of treatment and when any symptoms or signs of hepatotoxicity is necessary to conduct studies of the functions of the liver. If confirmed hepatotoxicity therapy cyproterone acetate is usually recommended to cancel, unless the hepatotoxicity not due to other causes, such as metastatic process. In this case, treatment should continue only if expected benefits outweigh the risks.
In rare cases after administration of sex hormones (which also includes the active component Androkura) were benign and even more rarely malignant liver tumors, in some cases leading to life-threatening intra-abdominal hemorrhage. If complaints of acute pain in the upper abdomen, liver enlargement or signs of acute intra-abdominal bleeding, the differential diagnosis should be considered possible liver tumor.
Patients suffering from diabetes, need careful medical supervision.
Reported occurrence of thromboembolic phenomena in patients receiving Androkur, although the causal relationships have been identified. In patients with previous thrombotic/thromboembolic diseases of arteries or veins (e.g. deep vein thrombosis, pulmonary embolism, myocardial infarction), disorders of cerebral circulation in the anamnesis or in the later stages of malignant disease the risk of thromboembolic complications is increased.
Androkurom in the treatment of patients with increased sexual desire in sexual disorders the use of alcohol can lead to reduced drug action.
Before the appointment Androkura patients with inoperable carcinoma of the prostate with thromboembolic syndrome in anamnesis, and in the presence of sickle-cell anemia or severe diabetes with vascular changes, in each individual case it is necessary to carefully evaluate the possible risks and expected benefits of treatment.
During treatment Androkurom be careful when driving and occupation of other potentially hazardous activities, require high concentration and psychomotor speed reactions, because the drug may lead to deterioration of these indicators.
It is necessary to avoid intravascular injection Androkur Depot.
Androkur, 100 mg
Treatment Androkurom should be under the control of the liver, adrenal cortex and picture peripheral blood.
If there are signs of hepatotoxicity, the drug should be discontinued.
In patients with diabetes mellitus may require dose adjustment of insulin or other hypoglycemic drugs (glucose monitoring should be performed more often than usual).
Androkura negative impact on fertility after cessation of treatment were observed.
During treatment should refrain from activities, require increased attention.
