What is Elleacnelle, and What Type of Medicine is It?

Elleacnelle, recognized by the generic International Nonproprietary Name (INN) Co-cyprindiol, is a synthetic, prescription-only combined hormonal medication provided as an oral coated tablet, known as a drajee. This medication is classified within the specialized group Antiandrogens and estrogens, which features a dual therapeutic action that sets it apart from standard combined oral contraceptives (COCs). This specific combination is used for providing management for hormonal imbalances and concurrently offers reliable contraception.


The Composition: Cyproterone Acetate and Ethinyl Estradiol

The medicine contains two active, synthetic steroidal ingredients: Cyproterone acetate (CPA) and Ethinyl Estradiol (EE2). Cyproterone acetate plays a pivotal role as a potent antiandrogen and a primary progestin, opposing the effects of male hormones in the body. Ethinyl Estradiol acts as the estrogen component, ensuring regulated cycle control and enhancing the antiandrogenic effect. Cyproterone acetate functions by binding to and inhibiting androgen receptors. The composition is designed for oral intake, facilitating systemic administration of the components.


What is the General Purpose of This Combination Drug?

The general purpose of this specific combined formulation is the systemic counteraction of androgens in women, addressing symptoms linked to excessive male hormone activity, or hyperandrogenism. A typical use scenario involves managing severe, persistent acne or clinically significant excessive hair growth (hirsutism). By working to lower the effective level of active male hormones, the formulation aims to mitigate these androgen-driven manifestations. Due to its hormonal nature, it also provides the function of reliable contraception.

What side effects are possible with Elleacnelle?

Possible Side Effects and Safety Information

The safety profile for Elleacnelle (Co-cyprindiol) is formally documented in regulatory texts, detailing adverse reactions by their likelihood and the body systems affected. These official classifications differentiate between common, less severe effects and rare, serious safety events.

Frequency-Classified Adverse Reactions

Adverse effects are categorized based on their frequency observed in clinical use:

  • Common: Nausea, abdominal pain, headache, depressed mood, breast pain/tenderness, and increase in body weight are frequently reported.
  • Uncommon: Vomiting, diarrhea, migraine, fluid retention, and rash are listed in this tier.
  • Rare: Serious events, including thromboembolism, are categorized as rare.

System-Organ Classes and Serious Safety Concerns

The most significant documented risks relate to Vascular Disorders. The official labeling explicitly highlights the potential for Venous and Arterial Thromboembolism (blood clots), which include events such as deep vein thrombosis, pulmonary embolism, stroke, and myocardial infarction. The risk of these events is highest during the first year a person uses this combination. Additionally, the label notes the potential for Liver Tumors (benign or malignant).

Exposure-Related and Population-Specific Safety

A specific, dose-dependent safety pattern is noted for the cyproterone acetate component: the risk of meningioma (a type of brain tumor) is associated with the cumulative dose taken over time. Safety constraints also exist for specific populations. Use is officially restricted in individuals with severe hepatic disease or a history of certain tumors. The risk of blood clots is increased for individuals over 35 years of age and for those with pre-existing risk factors like severe hypertension. Melasma (skin darkening) may be worsened by sunlight exposure.

Overdose and Emergency Response

Overdose and when to seek help

The regulatory classification of an Elleacnelle overdose focuses on documenting expected signs and mandating immediate medical evaluation.


Documented Overdose Manifestations

The officially documented clinical signs and symptoms of acute overdose primarily reflect hormonal excess. These manifestations commonly include nausea and vomiting, headache, and breast tenderness. A characteristic physiological effect is withdrawal bleeding (heavy vaginal bleeding), which may occur several days after the acute event. Other noted presentations include drowsiness, emotional changes, and discolored urine.


Emergency Actions and Required Care

It is mandatory to seek medical help right away if an overdose is suspected. Government guidance instructs contacting a local poison control center or calling the local emergency number. Regulatory data states that the acute overdose is generally not likely to be life-threatening. However, the acute event requires professional evaluation, especially if severe upper abdominal pain suggests a rare complication such as intra-abdominal hemorrhage.


Management and Monitoring

No specific antidotes are known for this combined hormonal formulation. Management is strictly symptomatic and supportive. This supportive treatment may include the use of activated charcoal in severe cases. Medical assessment involves measuring and monitoring vital signs and conducting blood and urine tests.

Therapeutic Uses of Elleacnelle

What Elleacnelle Treats: Main Uses and Benefits

In clinical contexts, Elleacnelle is commonly used for the management of specific androgen-dependent conditions in women of reproductive age.

Therapeutic Use Categories

Elleacnelle is primarily used to provide symptomatic relief for conditions presenting with severe manifestations, specifically severe, persistent acne that is considered relevant for management after other medical treatments have been tried, and moderately severe hirsutism (excessive hair growth). It is also commonly used across conditions characterized by chronic androgen excess, such as Polycystic Ovary Syndrome (PCOS), to assist with the regulation of the menstrual cycle. This generally contributes to improved day-to-day comfort and helps ease the impact of distressing manifestations. It also assists with maintaining functional stability by providing concurrent oral contraception while the patient is receiving management for these underlying hormonal issues.

Quick Fact: Relief for Androgen-Driven Skin Symptoms This medication is applied in scenarios where additional management of discomfort is required for symptoms that have not adequately responded to standard medical treatments.

Eligibility and Restrictions for Use

Elleacnelle (Co-cyprindiol) is formally indicated for use only in women of reproductive age who require treatment for specific androgen-dependent conditions, such as severe acne or moderately severe hirsutism [1.1, 2.5, 3.2]. It should only be prescribed when initial treatments, like topical therapy or systemic antibiotics, have failed [1.3]. Due to the increased risk of venous thromboembolism (VTE), it is contraindicated for several populations.

Contraindications and Restrictions

Classification Population/Condition
Absolute Contraindication History of, or current, thromboembolic disorders (e.g., DVT, stroke, PE, myocardial infarction) or severe thrombogenic risk factors [1.4, 2.1].
Absolute Contraindication Known or suspected pregnancy or lactation/breastfeeding [2.1].
Absolute Contraindication Current or history of meningioma, liver tumors, or hormone-sensitive cancers (e.g., breast cancer) [2.1, 3.2].
Restricted Use Women who smoke and are over 35 years old; those with severe uncontrolled hypertension; or those with severe diabetes mellitus with vascular changes [2.1].
Exclusionary Rule Must not be used solely for contraception or in combination with any other hormonal contraceptive [1.1, 1.3].

Treatment must be discontinued 3 to 4 cycles after the symptoms have completely resolved, and use is not applicable to children (pre-menarche) or older adults (post-menopause) [2.4, 3.2].

What should I know about interactions with other medicines?

Interactions with other medicines and products

This section describes the officially documented interaction patterns for Elleacnelle (Co-cyprindiol) as detailed in government regulatory labeling.

Formal Contraindications

Co-administration with other hormonal contraceptive products is formally contraindicated, as this combination results in an excessive dose of hormones. Additionally, co-administration is strictly prohibited with combination drug regimens for Hepatitis C that contain ombitasvir/paritaprevir/ritonavir pm dasabuvir, or products containing glecaprevir/pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir, due to the risk of liver enzyme elevations.

Pharmacokinetic Interactions

Interacting Agent Category Effect on Elleacnelle Components Example Agents
Hepatic Enzyme Inducers Reduces plasma concentration Rifampicin, Carbamazepine, Phenytoin
Hepatic Enzyme Inhibitors Increases plasma concentration Fluconazole, Clarithromycin, Verapamil
Enterohepatic Circulation Interruption Reduces Ethinyl Estradiol concentration Penicillins, Tetracyclines

Restrictions and Exposure Alteration

Exposure to hepatic enzyme-inducing agents necessitates the use of a non-hormonal barrier method during co-administration and for 28 days following the discontinuation of the inducing agent. This medicine also affects other drugs; for example, co-administration formally reduces the plasma concentration of Lamotrigine. Furthermore, the herbal product St. John’s Wort is documented to reduce the plasma concentration of the hormonal components. Due to clearance issues, the product is contraindicated in the presence of severe hepatic disease.

Mechanism of Action

Peripheral Receptor Blockade and Androgen Antagonism

This mechanism relies on Cyproterone acetate acting as a competitive antagonist at the Androgen Receptor (AR), particularly in cells of the skin and hair follicles. By binding to the AR, the molecule prevents endogenous androgens like Testosterone from initiating cellular activity. This results in a localized decrease in cellular responsiveness to androgen-mediated physiological signals at the tissue level.

Systemic Androgen Bioavailability Reduction

The Ethinyl Estradiol component initiates a systemic effect by stimulating the liver to increase the production of Sex Hormone-Binding Globulin (SHBG). This protein binds to the majority of circulating androgens, effectively converting them from their free, biologically active state into an inactive, bound state. This synergistic action reduces the quantity of active hormone available to reach target tissues.

Central Endocrine Axis Suppression

Both components provide negative feedback to the Hypothalamus-Pituitary-Ovarian (HPO) axis . This central suppression inhibits the release of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), resulting in anovulation and a reduction in the synthesis and secretion of endogenous ovarian androgens.

Dosage and Administration Information

How to Use Elleacnelle

Elleacnelle (Co-cyprindiol) is administered through a standardized oral cyclic regimen. The product is provided as a coated tablet containing 2.0 mg Cyproterone acetate and 0.035 mg Ethinylestradiol, which defines its fixed daily dose.


Administration and Scheduling

Route and Timing: The medication is for oral use and involves taking one tablet daily at approximately the same time each day. The tablet should be swallowed whole, with liquid if needed, without dependence on meals.

Dosing Schedule: Use follows a 21/7 regimen. This involves taking one active tablet daily for 21 consecutive days, followed by a 7-day tablet-free interval. Tablet-taking must adhere to the order directed on the blister pack, and the new 21-day course must begin immediately after the 7-day break.


Procedural Context and Duration

Use Constraints: Elleacnelle must not be used in combination with any other hormonal contraceptive product, as this would result in an excessive dose of hormones. If tablet intake is delayed by less than 12 hours, it should be taken immediately to maintain the intended use. If a single tablet is delayed by more than 12 hours, the regimen's effectiveness may be reduced.

Course Length: Treatment for the intended conditions requires a minimum duration, generally at least 3 months, before a determination of effectiveness can be made. The treatment should be discontinued 3 to 4 cycles after the clinical condition has completely resolved, as the preparation is not intended for continued use solely as a contraceptive.

Recent Clinical Evidence

Research Evidence / Overview of Studies for Elleacnelle


Evidence for Use in Severe, Persistent Acne

Research has explored the use of this medicine for conditions related to severe, persistent acne, primarily through short-term to intermediate-term clinical trials. These studies focused on women of reproductive age, including adolescent females, who were studied in research settings after other prior medical treatments.

The main outcomes related to physical discomfort that were measured during the study period included changes in skin lesion counts and clinician assessment of the skin condition. Findings describe patterns observed in the studies over the typical study duration of three to six months.

Evidence for Use in Moderately Severe Excessive Hair Growth (Hirsutism)

This combination was evaluated in women with moderately severe excessive hair growth (hirsutism). Research included both clinical trials and long-term observational settings which tracked the course of the condition. The primary clinical measurement used was the Ferriman-Gallwey Score (FG Score), a standardized system for objectively monitoring hair growth, along with biomarker outcomes related to systemic or functional imbalance, such as androgen hormone levels.

What is Still Uncertain About Elleacnelle Research

Despite the existing body of research, several areas remain uncertain. Comparative evidence is lacking or findings were mixed when the medicine was evaluated in direct comparisons against other combined oral contraceptives that were studied.

Furthermore, data for certain groups remain insufficient. Sample sizes were modest in some comparative trials, and there is limited information for long-term outcomes regarding the durability of any response, as most high-quality trials had follow-up durations that were limited.
