4    CLINICAL PARTICULARS

4.1 Therapeutic indications

Oral contraception

The decision to prescribe Gedarel should take into consideration the individual woman’s current risk factors, particularly those for venous thromboembolism (VTE), and how the risk of VTE with Gedarel compares with other combined hormonal contraceptives (CHCs) (see sections 4.3 and 4.4).

4.2 Posology and method of administration

Posology

How to take Gedarel

The tablets must be taken in the order directed on the package every day at about the same time of the day. One tablet is taken daily for 21 consecutive days. Each subsequent pack is started after a 7-day tablet-free interval;during which time a

withdrawal bleed usually occurs. This usually starts on day 2-3 after last tablet and may not have finished, before the next pack is started.

How to start Gedarel

No preceding hormonal contraceptive use [in the past month]

The tablet intake should be started on day 1 of the normal menstrual cycle (i.e. on the first day on which the woman has a menstrual bleeding). Tablet intake is also allowed to start on day 2-5, but during the first cycle concurrent use of a barrier method for the first 7 days of tablet intake is advisable.

Changing from a combined oral contraceptive (COC), combined contraceptive vaginal ring or transdermal patch

The woman should start taking Gedarel on the day after the last active tablet (the last tablet containing the active substance) of her previous COC, but at the latest on the day following the usual tablet-free interval or following the last placebo tablet (tablet containing no active substance) of her previous COC.

In case a vaginal ring or a transdermal patch has been used,it is preferable to start using Gedarel on the day of its removal. The woman may also start using Gedarel on the day the next vaginal ring or the next transdermal patch would have been due, but no later than this day.

If the woman has used her previous contraception method regularly and correctly and if the woman is not pregnant she may also change from her previous hormonal contraception on any day during the cycle.

The hormone-free period from the previous contraception method must not be extended for longer than recommended.

Not all administration methods of hormonal contraception (transdermal patch, vaginal ring) is necessarily marketed in all EU countries.

Changing from progestogen only products (progetogen-only-pills, injection, implant, a progestogen-releasing intrauterine system (IUS)

The woman can change from progestogen-only pills on any day (changing from implant or IUS on the day of its removal; changing from injection when the next injection should have been given) but should in all of these cases be advised to additionally use a barrier method for the first 7 days of tablet-taking.

After abortion in the 1st trimester

Tablet intake should start immediately. In this case no further contraceptive measures are necessary.

After delivery or abortion in the 2nd trimester For breast-feeding women - see section 4.6.

The woman should be advised to start the pill on day 21-28 after delivery or abortion in the 2nd trimester. She should be advised to use a barrier method concurrently during the first 7 days of tablet intake if she starts the pill later. In case she has already had intercourse, pregnancy should be excluded before she starts taking Gedarel, or she should wait for her first menstrual bleeding.

Forgotten tablets

If the tablet intake is forgotten for less than 12 hours, contraceptive protection is not reduced. The woman should take the forgotten tablet as soon as she remembers, and the remaining tablets are taken as usual.

If the tablet intake is forgotten for more than 12 hours, contraceptive protection may be reduced. The following two basic rules should be considered in case of forgotten tablets:

1.    Continuous tablet intake must not be interrupted for longer than a period of 7 days.

2.    7 days of uninterrupted tablet intake are required to achieve sufficient suppression of the hypothalamus-pituitary-ovarian-axis.

Thus, the following advice may be given for daily practice:

Week 1

The woman should take the last forgotten tablet as soon as she remembers, even if this means that she has to take 2 tablets at the same time. Then, she continues taking the tablets at the usual time of the day. She should concurrently use a barrier method, e.g. a condom, for the next 7 days. If intercourse has taken place during the preceding 7 days, the possibility of pregnancy should be considered. The more tablets are forgotten and the closer they are to the regular tablet-free period, the higher the risk of pregnancy is.

Week 2

The woman should take the last forgotten tablet as soon as she remembers, even if this means that she has to take 2 tablets at the same time. Then, she continues taking the tablets at the usual time of the day. Provided that the tablets have been taken in a correct manner during the 7 days preceding the forgotten tablet, it is not necessary to take further contraceptive measures. However, if this is not the case, or if more than 1 tablet has been forgotten, the woman should be advised to use another contraceptive method for 7 days.

Week 3

The risk of reduced contraceptive protection is imminent due to the next tablet-free period. However, this risk may be prevented by adjusting tablet intake. Thus, it is not necessary to take further contraceptive measures if one of the two alternatives below is followed, provided that all tablets have been taken in a correct manner during the 7 days preceding the forgotten tablet. If this is not the case, the woman should be advised to follow the first of the two alternatives and concurrently use another contraceptive method for the next 7 days.

1 The user should take the last forgotten tablet as soon as she remembers even if it means that she has to take 2 tablets at the same time. Then she continues taking the tablets at the usual time of the day. She will begin taking the next pack immediately after taking the last tablet in the present pack, i.e. there is no break between the packs. It is not very likely that the user will have her menstrual bleeding until the end of the second pack, but she may experience spotting or break-through bleeding on the days she is taking tablets.

2. The woman may also be advised to stop taking tablets from the present pack. In that case she should keep a tablet-free period of up to 7 days, including those days when she forgot tablets, and then continue with the next pack.

In case the woman has forgotten tablets and then does not have her menstrual bleeding in the first normal tablet-free period, the possibility of pregnancy should be considered

Advice in case of gastrointestinal disturbances

In case of severe gastro-intestinal disturbances, absorption may not be complete and additional contraceptive measures should be taken.

If vomiting occurs within 3-4 hours after taking the active tablets, the advice concerning missed tablets, as given above, is applicable. If the woman does not want to change her normal tablet-taking schedule, she has to take the extra tablet(s) needed from another pack.

How to postpone a withdrawal bleed

There is no indication for this product to postpone menstruation. However, in extraordinary cases, if postponing menstruation is required the woman should continue with another blister pack of Gedarel without a tablet-free interval. The extension can be carried on for as long as wished until the end of the second pack. During the extension the woman may experience breakthrough-bleeding or spotting. Regular intake of Gedarel is then resumed after the usual 7-day tablet-free interval To shift her periods to another day of the week than the woman is used to with her current scheme, she can be advised to shorten her forthcoming tablet-free interval by as many days as she likes. The shorter the interval, the higher the risk that she does not have a withdrawal bleed and will experience breakthrough-bleeding and spotting during the subsequent pack (just as when delaying a period).

Paediatric population

The safety and efficacy of desogestrel in adolescents below 18 years has not yet been established. No data are available.

Method of administration For oral administration.

4.3 Contraindications

4.4 Special warnings and precautions for use

Warnings

If any of the conditions or risk factors mentioned below is present, the suitability of Gedarel should be discussed with the woman.

In the event of aggravation, or first appearance of any of these conditions or risk factors, the woman should be advised to contact her doctor to determine whether the use of Gedarel should be discontinued.

Circulatory disorders

Risk of venous thromboembolism (VTE)

The use of any combined hormonal contraceptive (CHC) increases the risk of venous thromboembolism (VTE) compared with no use. Products that contain levonorgestrel, norgestimate or norethisterone are associated with the lowest risk of VTE. Other products such as Gedarel may have up to twice this level of risk. The decision to use any product other than one with the lowest VTE risk should be taken only after a discussion with the woman to ensure she understands the risk of VTE with Gedarel, how her current risk factors influence this risk, and that her VTE risk is highest in the first ever year of use. There is also some evidence that the risk is increased when a CHC is re-started after a break in use of 4 weeks or more.

In women who do not use a CHC and are not pregnant about 2 out of 10,000 will develop a VTE over the period of one year. However, in any individual woman the risk may be far higher, depending on her underlying risk factors (see below).

It is estimated1 that out of 10,000 women who use a CHC containing desogestrel between 9 and 12 women will develop a VTE in one year; this compares with about 62 in women who use a levonorgestrel-containing CHC.

In both cases, the number of VTEs per year is fewer than the number expected during pregnancy or in the postpartum period.

VTE may be fatal in 1-2% of cases.

Number of VTE events per 10,000 women in one year

Extremely rarely, thrombosis has been reported to occur in CHC users in other blood vessels, e.g. hepatic, mesenteric, renal or retinal veins and arteries.

Risk factors for VTE

The risk for venous thromboembolic complications in CHC users may increase substantially in a woman with additional risk factors, particularly if there are multiple risk factors (see table).

Gedarel is contraindicated if a woman has multiple risk factors that put her at high risk of venous thrombosis (see section 4.3). If a woman has more than one risk factor, it is possible that the increase in risk is greater than the sum of the individual factors -in this case her total risk of VTE should be considered. If the balance of benefits and risks is considered to be negative a CHC should not be prescribed (see section 4.3).

be a risk factor for VTE, particularly in women with other risk factors.

Positive family history (venous thromboembolism ever in a sibling or parent especially at a relatively early age e.g. before 50).

If a hereditary predisposition is suspected, the woman should be referred to a specialist for advice before deciding about any CHC use.

Other medical conditions associated with VTE.

Cancer, systemic lupus erythematosus, haemolytic uraemic syndrome, chronic inflammatory bowel disease (Crohn’s disease or ulcerative colitis) and sickle cell disease.

Increasing age.

Particularly above 35 years.

There is no consensus about the possible role of varicose veins and superficial thrombophlebitis in the onset or progression of venous thrombosis.

The increased risk of thromboembolism in pregnancy, and particularly the 6 week period of the puerperium, must be considered (for information on “Pregnancy and lactation” see section 4.6).

Symptoms of VTE (deep vein thrombosis and pulmonary embolism)

In the event of symptoms women should be advised to seek urgent medical attention and to inform the healthcare professional that she is taking a CHC.

Symptoms of deep vein thrombosis (DVT) can include:

-    unilateral swelling of the leg and/or foot or along a vein in the leg;

-    pain or tenderness in the leg which may be felt only when standing or walking;

-    increased warmth in the affected leg; red or discoloured skin on the leg. Symptoms of pulmonary embolism (PE) can include:

-    sudden onset of unexplained shortness of breath or rapid breathing;

-    sudden coughing which may be associated with haemoptysis;

-    sharp chest pain, whether or not it radiates to the left arm;

-    severe light headedness or dizziness;

-    rapid or irregular heartbeat.

Some of these symptoms (e.g. “shortness of breath”, “coughing”) are non-specific and might be misinterpreted as more common or less severe events (e.g. respiratory tract infections).

Other signs of vascular occlusion can include: sudden pain, swelling and slight blue discoloration of an extremity.

If the occlusion occurs in the eye symptoms can range from painless blurring of vision which can progress to loss of vision. Sometimes loss of vision can occur almost immediately.

Risk of arterial thromboembolism (ATE)

Epidemiological studies have associated the use of CHCs with an increased risk for arterial thromboembolism (myocardial infarction) or for cerebrovascular accident (e.g. transient ischaemic attack, stroke). Arterial thromboembolic events may be fatal.

Risk factors for ATE

The risk of arterial thromboembolic complications or of a cerebrovascular accident in CHC users increases in women with risk factors (see table). Gedarel is contraindicated if a woman has one serious or multiple risk factors for ATE that puts her at high risk of arterial thrombosis (see section 4.3). If a woman has more than one risk factor, it is possible that the increase in risk is greater than the sum of the individual factors - in this case her total risk should be considered. If the balance of benefits and risks is considered to be negative a CHC should not be prescribed (see section 4.3).

If a hereditary predisposition is suspected, the woman should be referred to a specialist for advice before deciding about any CHC use.

Migraine.

An increase in frequency or severity of migraine during CHC use (which may be prodromal of a cerebrovascular event) may be a reason for immediate discontinuation.

Other medical conditions associated with adverse vascular events.

Diabetes mellitus, hyperhomocysteinaemia, valvular heart disease and atrial fibrillation, dyslipoproteinaemia and systemic lupus erythematosus.

Symptoms of ATE

In the event of symptoms women should be advised to seek urgent medical attention and to inform the healthcare professional that she is taking a CHC.

Symptoms of a cerebrovascular accident can include:

-    sudden numbness or weakness of the face, arm or leg, especially on one side of

the body;

-    sudden trouble walking, dizziness, loss of balance or coordination;

-    sudden confusion, trouble speaking or understanding;

-    sudden trouble seeing in one or both eyes;

-    sudden, severe or prolonged headache with no known cause;

-    loss of consciousness or fainting with or without seizure.

Temporary symptoms suggest the event is a transient ischaemic attack (TIA).

Symptoms of myocardial infarction (MI) can include:

-    pain, discomfort, pressure, heaviness, sensation of squeezing or fullness in the

chest, arm, or below the breastbone;

-    discomfort radiating to the back, jaw, throat, arm, stomach;

-    feeling of being full, having indigestion or choking;

-    sweating, nausea, vomiting or dizziness;

-    extreme weakness, anxiety, or shortness of breath;

-    rapid or irregular heartbeats.

Tumours

Epidemiological studies indicate that the long-term use of oral contraceptives displays an additional risk factor for the development of cervical cancer in women infected with human papillomavirus (HPV). However, there is still uncertainty about the extent to which this finding may be influenced by confounding effects (e.g. differences in number of sexual partners or in use of barrier contraceptives).

A meta-analysis from 54 epidemiological studies reported that there is a slightly increased relative risk (RR = 1.24) of having breast cancer diagnosed in women who are currently using combined oral contraceptives (CHCs). This increased risk gradually declines for 10 years after cessation of COCs. Since breast cancer is a rare condition in women below 40 years of age, the increase in the number of diagnosed cases of breast cancer in present and former users of COCs is low compared to the risk of breast cancer in their entire lifetime. These studies do not put forward evidence of a causal relationship. The observed pattern of an increased risk may be due to an earlier diagnosing of breast cancer in users of COCs, the biological effects of COCs or a combination of both. The diagnosed cases of breast cancer in users of COCs have a tendency to be less clinically advanced compared to the diagnosed cases of breast cancer in never-users.

In rare cases, benign liver tumours, and even more rarely, malignant liver tumours have been reported in users of CHCs. In isolated cases, these tumours have led to life-threatening intra-abdominal haemorrhages. A hepatic tumour should be considered in the differential diagnosis when severe upper abdominal pain, liver enlargement or signs of intra-abdominal haemorrhage occur in women taking CHCs.

Other conditions

Women with hypertriglyceridaemia or a family history thereof, may be at an increased risk of pancreatitis when taking CHCs.

Although small increases in blood pressure have been reported in many women taking CHCs, clinically relevant increases are rare. A systematic relationship between CHC use and clinical hypertension has not been established. However, if a sustained clinically significant hypertension develops during the use of a CHC then it is prudent for the physician to withdraw the COC and treat the hypertension. Where considered appropriate, CHC use may be resumed if normotensive values can be achieved with antihypertensive therapy.

The following conditions have been reported to occur or deteriorate with both pregnancy and CHC use, but the evidence of a relationship with CHC use is inconclusive: jaundice and/or itching in connection with cholestasis; gallstone formation; porphyria; systemic lupus erythematosus; haemolytic uraemic syndrome; Sydenham’s chorea; herpes gestationis; otosclerosis-related hearing loss; (hereditary) angioedema.

Acute or chronic disturbances of liver function may necessitate discontinuation of COC use until liver function parameters have been normalised. Recurrent of cholestatic jaundice which occurred first during pregnancy or previous use of sex steroids necessitates the discontinuation of COCs.

Although CHCs may have an effect on peripheral insulin resistance and glucose tolerance, there is no evidence for a need to alter the therapeutic regimen in diabetics using CHCs. However, diabetic women should be carefully observed while taking CHCs.

Crohn’s disease and ulcerative colitis have been associated with CHC use.

Chloasma may occasionally occur, especially in women with a history of chloasma gravidarum. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation whilst taking CHCs.

This medicinal product contains <65 mg lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

When counselling the choice of contraceptive method(s), all the above information should be taken into account.

Medical examination/consultation

Prior to the initiation or reinstitution of Gedarel a complete medical history (including family history) should be taken and pregnancy must be ruled out. Blood pressure should be measured and a physical examination should be performed, guided by the contra-indications (see section 4.3) and warnings (see section 4.4). It is important to draw a woman’s attention to the information on venous and arterial thrombosis, including the risk of Gedarel compared with other CHCs, the symptoms of VTE and ATE, the known risk factors and what to do in the event of a suspected thrombosis. The woman should also be instructed to carefully read the user leaflet and to adhere to the advice given. The frequency and nature of examinations should be based on established practice guidelines and be adapted to the individual woman.

Women should be advised that hormonal contraceptives do not protect against HIV infections (AIDS) and other sexually transmitted diseases.

Reduced efficacy

The efficacy of Gedarel may be reduced in the event of e.g., missed tablets (section 4.2), gastro-intestinal disturbances (section 4.2) or concomitant medication (section 4.5).

Herbal preparations containing St. John's wort (Hypericum perforatum) should not be used while taking Gedarel due to the risk of decreased plasma concentrations and reduced clinical effects of Gedarel (see section 4.5).

Reduced cycle control

With all CHCs irregular bleeding (spotting or breakthrough bleeding) may occur, especially during the first months of use. Therefore, the evaluation of any irregular bleeding is only meaningful after an adaptation interval of about three cycles.

If bleeding irregularities persist or occur after previously regular cycles, then nonhormonal causes should be considered and adequate diagnostic measures are indicated to exclude malignancy or pregnancy. These may include curettage.

In some women withdrawal bleeding may not occur during the tablet-free interval. If the CHC has been taken according to the directions described in Section 4.2, it is unlikely that the woman is pregnant. However, if the CHC has not been taken according to these directions prior to the first missed withdrawal bleed or if two withdrawal bleeds are missed, pregnancy must be ruled out before CHC use is continued.

4.5 Interaction with other medicinal products and other forms of interaction

Note: The prescribing information of concomitant medications should be consulted to identify potential interactions.

Effects of other medicinal products on Gedarel

Interactions can occur with drugs that induce microsomal enzymes which can result in increased clearance of sex hormones and which may lead to breakthrough bleeding and/or oral contraceptive failure.

Management

Enzyme induction can already be observed after a few days of treatment. Maximal enzyme induction is generally seen within a few weeks. After the cessation of drug therapy enzyme induction may be sustained for about 4 weeks.

Short-term treatment

Women on treatment with enzyme inducing drugs should temporarily use a barrier method or another method of contraception in addition to the COC. The barrier method must be used during the whole time of the concomitant drug therapy and for 28 days after its discontinuation.

If the drug therapy runs beyond the end of the tablets in the COC pack, the next COC pack should be started right after the previous one without the usual tablet-free interval.

Long-term treatment

In women on long-term treatment with enzyme-inducing active substances, another reliable, non-hormonal, method of contraception is recommended.

The following interactions have been reported in the literature.

Substances increasing the clearance of COCs (diminished efficacy of COCs by enzyme-induction), e.g.:

Barbiturates, bosentan, carbamazepine, phenytoin, primidone, rifampicin, and HIV medication ritonavir, nevirapine and efavirenz and possibly also felbamate, griseofulvin, oxcarbazepine, topiramate and products containing the herbal remedy St. John's Wort (Hypericum perforatum).

Substances with variable effects on the clearance of COCs:

When co-administered with COCs, many combinations of HIV protease inhibitors and non-nucleoside reverse transcriptase inhibitors, including combinations with HCV inhibitors can increase or decrease plasma concentrations of estrogen or progestins. The net effect of these changes may be clinically relevant in some cases.

Therefore, the prescribing information of concomitant HIV/HCV medications should be consulted to identify potential interactions and any related recommendations. In case of any doubt, an additional barrier contraceptive method should be used by women on protease inhibitor or non-nucleoside reverse transcriptase inhibitor therapy.

Substances decreasing the clearance of COCs (enzyme inhibitors):

The clinical relevance of potential interactions with enzyme inhibitors remains unknown.

Concomitant administration of strong CYP3A4 inhibitors can increase plasma concentrations of the estrogen or the progestin or both.

Etoricoxib doses of 60 to 120 mg/day have been shown to increase plasma concentrations of ethinylestradiol 1.4 to 1.6-fold, respectively when taken

concomitantly with a combined hormonal contraceptive containing 0.035 mg ethinylestradiol.

Effects of Gedarel on other medicinal products

COCs may interfere with the metabolism of other active substances. Accordingly, plasma and tissue concentrations may either increase (e.g. ciclosporin) or decrease (e.g. lamotrigine).

Clinical data suggest that ethinylestradiol is inhibiting the clearance of CYPIA2 substrates leading to a weak (e.g.theopylylline) or moderate (e.g. tizanidine) increase in their plasma concentration.

Levothyroxine

Oestrogen therapy may lead to a reduction of free thyroxine and increase of TSH in hypothyroid women treated with levothyroxine.

The combination may be used with dose adjustment.

Laboratory tests

The use of contraceptive steroids may influence on the results of certain laboratory tests, including biochemical parameters of liver, thyroid, adrenal and renal function, the plasma levels of (carrier)-proteins, e.g. corticosteroid-binding globulin and lipid/lipoprotein fractions, parameters of carbohydrate metabolism and parameters of coagulation and fibrinolysis. Changes generally remain within the normal laboratory range.

4.6 Fertility, pregnancy and lactation

Pregnancy

Gedarel is not indicated in pregnancy.

If pregnancy occurs during treatment with Gedarel, further intake should be stopped. However, extensive epidemiological studies have revealed neither an increased risk of birth defects in children born to women taking CHCs before pregnancy, nor any teratogenic effect when CHCs were taken inadvertently during early pregnancy.

The increased risk of VTE during the postpartum period should be considered when restarting Gedarel (see sections 4.2 and 4.4).

Breastfeeding

Lactation may be influenced by CHCs as they may reduce the quantity and change the composition of breast milk. Therefore, the use of CHCs should generally not be recommended until the nursing mother has completely weaned her child. Small amounts of the contraceptive steroids and/or their metabolites may be excreted with the milk, but there is no evidence that this adversely affects infant health.

4.7 Effects on ability to drive and use machines

Gedarel has no influence or negligible influence on the ability to drive and use machines.

4.8 Undesirable effects

In the first part of the treatment period a large part (10-30%) of the women may expect to get side effects such as breast tenderness, malaise and spot bleeding. However, these side effects are usually temporary and disappear after 2-4 months.

Description of selected adverse reactions

An increased risk of arterial and venous thrombotic and thromboembolic events, including myocardial infarction, stroke, transient ischaemic attacks, venous thrombosis and pulmonary embolism has been observed in women using CHCs, which are discussed in more detail in section 4.4.

Other side effects have been reported in women using combined hormonal contraceptives. These are described in section 4.4.

As with all CHCs, changes in vaginal bleeding patterns may occur, especially during the first months of use. These may include changes in bleeding frequency (absent, less, more frequent or continuous), intensity (reduced or increased) or duration.

Possibly related undesirable effects that have been reported in users of Gedarel and users of combined hormonal contraceptives in general are listed in the table below3. All ADRs are listed by system organ class and frequency; very common (>1/10), common (>1/100 to <1/10), uncommon (>1/1,000 to <1/100) and rare (>1/10,000 to <1/1,000).

Interactions

Breakthrough bleeding and/or contraceptive failure may result from interactions of other drugs (enzyme inducers) with oral contraceptives (see section 4.5).

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

4.9 Overdose

There have been no reports of serious deleterious effects from overdose.

Symptoms

Symptoms that may occur in this case are: nausea, vomiting and, in young girls, slight vaginal bleeding.

Treatment

There are no antidotes and further treatment should be symptomatic.

Pharmacotherapeutic group: Hormonal contraceptives for systemic use, Progestogens and estrogens, fixed combinations, ATC code: G03AA09

Mechanism of action

The contraceptive action of CHCs is based on interaction of different factors, out of which the most important is the inhibition of ovulation and changes in the cervical secretion. Besides protection against pregnancy, CHCs have several positive properties which, next to the negative properties (see sections 4.4 and 4.8), can be useful in deciding on the method of birth control. The cycle is more regular and the menstruation is often less painful and bleeding is lighter. The latter may result in a decrease in the occurrence of iron deficiency.

Also it seems that the risk of endometrial cancer and ovarian cancer is reduced. Furthermore, it has been shown that high dosed combined hormonal contraceptives (50 microgram ethinyl estradiole) reduce the risk of ovarian cysts, pelvic inflammatory disease, benign breast disorders, ectopic pregnancy and endometrial and ovarian cancer. Whether this also is the case for low dose combined hormonal contraceptives is not yet confirmed.

Paediatric population

No clinical data on efficacy and safety are available in adolescents below 18 years.

5.2 Pharmacokinetic properties

Desogestrel

Absorption

Orally administered desogestrel is rapidly and completely absorbed and converted to etonogestrel. Following ingestion of a single dose, peak serum concentrations of about 2 ng/mL are reached within 1.5 hours. Bioavailability is 62-81%.

Distribution

Etonogestrel is bound to serum albumin and to sex hormone binding globulin (SHBG). Only 2-4 % of the total serum drug concentrations are present as free steroid, 40-70 % are specifically bound to SHBG. The ethinylestradiol-induced increase in SHBG influences the distribution of the serum proteins, causing an increase of the SHBG-bound fraction and a decrease of the albumin-bound fraction. The apparent volume of distribution of desogestrel is 1.5 l/kg.

Biotransformation

Etonogestrel is completely metabolized by the known pathways of steroid metabolism. The metabolic clearance rate from serum is about 2 ml/min/kg. No interaction was found with the co-administered ethinylestradiol.

Elimination

Etonogestrel serum levels decrease in two phases. The terminal disposition phase is characterized by a half-life of approximately 30 hours. Desogestrel and its metabolites are excreted at a urinary to biliary ratio of about 6:4.

Steady-state conditions

Etonogestrel pharmacokinetics are influenced by SHBG levels, which are increased threefold by ethinylestradiol. Following daily ingestion, drug serum levels increase about two- to threefold, reaching steady state conditions during the second half of a treatment cycle.

Ethinylestradiol

Absorption

Orally administered ethinylestradiol is rapidly and completely absorbed. Following ingestion of a single dose, peak serum concentrations of about 80 pg/mL are reached within 1-2 hours. Absolute bioavailability as a result of presystemic conjugation and first-pass metabolism is approximately 60%.

Distribution

Ethinylestradiol is highly but non-specifically bound to serum albumin (approximately 98.5%) and induces an increase in the serum concentrations of SHBG. An apparent volume of distribution of about 5 l/kg was determined.

Biotransformation

Ethinylestradiol is subject to presystemic conjugation in both small bowel mucosa and the liver. Ethinylestradiol is primarily metabolized by aromatic hydroxylation but a wide variety of hydroxylated and methylated metabolites are formed, and these are present as free metabolites and as conjugates with glucuronides and sulfate. The metabolic clearance rate is about 5 ml/min/kg.

Elimination

Ethinylestradiol serum levels decrease in two phases, the terminal disposition phase is characterized by a half-life of approximately 24 hours. Unchanged drug is not excreted, ethinylestradiol metabolites are excreted at a urinary to biliary ratio of 4:6. The half-life of metabolite excretion is about 1 day.

Steady-state conditions

Steady state concentrations are reached after 3-4 days when serum drug levels are higher by 30-40% as compared to single dose.

5.3 Preclinical safety data

Preclinical studies on ethinylestradiol and desogestrel revealed no special hazard for humans based on conventional studies of repeated dose toxicity, genotoxicity, carcinogenic potential and toxicity to reproduction.

However, it must be borne in mind that sex steroids can promote the growth of certain hormone-dependent tissues and tumours.
