What are the active ingredients in Eloine? A Detailed Pharmacological Review

4 min read

Eloine is a low-dose combined oral contraceptive pill that is over 99% effective at preventing pregnancy when taken correctly [1.3.3, 1.8.6]. This article answers 'What are the active ingredients in Eloine?' and explores their pharmacological action, benefits, and side effects.

Quick Summary

Eloine's active ingredients are 3 mg of drospirenone and 0.02 mg of ethinylestradiol [1.2.1]. These hormones prevent pregnancy by inhibiting ovulation, altering cervical mucus, and changing the uterine lining [1.8.2].

Key Points

  • Active Ingredients: Eloine contains two active ingredients: 3 mg of drospirenone (a progestogen) and 0.02 mg of ethinylestradiol (an estrogen) [1.2.1].

  • Primary Use: It is primarily used as a combined oral contraceptive to prevent pregnancy, with an efficacy rate of over 99% when taken correctly [1.3.3].

  • Mechanism of Action: The hormones work by preventing ovulation, thickening cervical mucus to impede sperm, and altering the uterine lining to prevent implantation [1.5.1, 1.8.2].

  • Other Uses: Eloine is also approved for treating moderate acne and the symptoms of premenstrual dysphoric disorder (PMDD) in women who choose it for birth control [1.2.1].

  • Low-Dose Formulation: It is considered a low-dose pill due to the smaller amount of estrogen, which can help reduce certain side effects like bloating and nausea [1.3.6].

  • Regimen: Eloine follows a 24/4 regimen, with 24 active hormone tablets and 4 inactive placebo tablets, taken continuously without a pill-free break [1.2.2].

  • Key Risks: Like other combined pills, Eloine increases the risk of blood clots. It is not suitable for everyone, especially women with a history of certain medical conditions [1.4.6, 1.5.3].

Understanding Eloine: A Low-Dose Combined Contraceptive

Eloine is a prescription medication primarily used as an oral contraceptive to prevent pregnancy [1.8.1]. It is classified as a low-dose, monophasic combined oral contraceptive, often referred to as "the Pill" [1.8.1]. Each pack contains 24 active tablets (light pink) and 4 inactive, or placebo, tablets (white) [1.2.2]. This 24/4-day regimen provides a continuous daily pill-taking schedule, which can be easier for some users to follow compared to traditional 21/7-day cycles [1.3.6]. Beyond contraception, Eloine is also prescribed for treating moderate acne vulgaris and the symptoms of premenstrual dysphoric disorder (PMDD) in women seeking oral contraception [1.2.1, 1.5.5]. The efficacy of Eloine for PMDD, however, has not been assessed beyond three cycles [1.2.1].

The Active Ingredients: Drospirenone and Ethinylestradiol

The therapeutic effects of Eloine are derived from its two active ingredients. Each pink, active tablet contains a precise combination of two female hormones:

  • Drospirenone (3 mg): A synthetic progestogen, which is a man-made version of the naturally occurring hormone progesterone [1.2.3, 1.8.3].
  • Ethinylestradiol (0.02 mg): A synthetic estrogen [1.2.3, 1.8.3].

Because it contains these two types of hormones, Eloine is categorized as a combined pill [1.8.1]. The term "low-dose" refers to its smaller amount of ethinylestradiol compared to some other standard combined pills, which may help reduce the risk of certain estrogen-related side effects like nausea and bloating [1.3.6]. The combination of these specific doses makes Eloine effective for its intended uses.

Mechanism of Action: How Eloine Works

The primary way combination oral contraceptives like Eloine prevent pregnancy is by suppressing gonadotropins, which inhibits ovulation (the release of an egg from the ovary) [1.5.1, 1.5.3]. The hormones in Eloine essentially make the body think ovulation has already occurred [1.3.6]. In addition to preventing ovulation, the active ingredients induce other changes that contribute to its contraceptive efficacy:

  1. Thickening of Cervical Mucus: The progestin component, drospirenone, makes the mucus in the cervix thicker. This creates a barrier that makes it more difficult for sperm to enter the uterus and reach an egg [1.5.2, 1.8.2].
  2. Alteration of the Endometrium: The hormones also thin the lining of the uterus (the endometrium) [1.8.2]. This makes the uterine environment less receptive to the implantation of a fertilized egg, should fertilization occur [1.5.1].

Drospirenone has unique properties among progestins. It is an analogue of spironolactone and possesses antimineralocorticoid and antiandrogenic activities [1.5.3, 1.5.6]. The antiandrogenic effects can help improve conditions like acne, while the antimineralocorticoid activity may help reduce water retention, a symptom sometimes associated with other contraceptive pills [1.5.1, 1.5.2].

Eloine Compared to Other Contraceptives

It's useful to understand how Eloine compares to other common oral contraceptives, particularly Yaz and Yasmin, as they contain similar ingredients.

Feature Eloine / Yaz Yasmin Other Low-Dose Pills (e.g., Gedarel 20/150)
Ethinylestradiol Dose 0.02 mg (low dose) [1.2.5] 0.03 mg (standard dose) [1.5.2] 0.02 mg (low dose) [1.3.6]
Progestin 3 mg Drospirenone [1.2.5] 3 mg Drospirenone [1.8.5] Different progestin (e.g., 150 mcg Desogestrel) [1.8.5]
Regimen 24 active + 4 placebo pills [1.2.2] 21 active + 7 placebo/break days [1.5.2] Varies, often 21/7 or 28-day packs [1.3.6]
Primary Use Contraception, moderate acne, PMDD [1.2.1] Contraception [1.8.5] Contraception [1.3.6]

Eloine is essentially the UK brand for the medication known as Yaz in the US; they contain the same active ingredients in the same doses [1.6.3, 1.6.5]. The main difference between Eloine and Yasmin is the estrogen dose; Yasmin contains a higher amount of ethinylestradiol (0.03 mg) and follows a 21/7 day cycle [1.8.5, 1.5.2].

Potential Side Effects and Considerations

Like all medications, Eloine can cause side effects. Common side effects often experienced during the initial adjustment period include mood swings, headaches, nausea, breast tenderness, and irregular bleeding or spotting [1.4.4, 1.4.5]. While many women do not experience side effects, it's important to be aware of the possibilities [1.4.3]. Low-dose pills like Eloine may have a higher incidence of irregular bleeding compared to standard-dose pills, though this often resolves within a few months [1.3.6, 1.4.3].

More serious, though rare, side effects are associated with combined hormonal contraceptives. A significant risk is the increased likelihood of developing blood clots (venous thromboembolism) compared to non-users [1.4.6]. This risk is highest during the first year of use [1.4.5]. For this reason, Eloine is contraindicated in women with a history of blood clots, certain cancers, severe liver disease, uncontrolled high blood pressure, and other specific medical conditions [1.4.4]. It is also not recommended for women over 35 who smoke [1.5.3].

Conclusion

The active ingredients in Eloine are 0.02 mg of ethinylestradiol and 3 mg of drospirenone, a combination that makes it a highly effective low-dose oral contraceptive [1.2.1, 1.3.3]. Its multifaceted mechanism of action—inhibiting ovulation, thickening cervical mucus, and thinning the uterine lining—provides robust protection against pregnancy [1.8.2]. Furthermore, the specific properties of drospirenone offer additional benefits for some users, such as the treatment of moderate acne and PMDD symptoms [1.2.1]. As a prescription medication, a thorough consultation with a healthcare provider is essential to determine if Eloine is a safe and appropriate contraceptive choice based on an individual's health profile and needs.

Frequently Asked Questions

The two active ingredients in Eloine are 3 mg of drospirenone and 0.02 mg of ethinylestradiol [1.2.1].

Eloine is a combination pill because it contains two types of hormones: a progestin (drospirenone) and an estrogen (ethinylestradiol) [1.8.1, 1.8.5].

Eloine prevents pregnancy in three main ways: it stops the release of an egg from the ovaries (ovulation), thickens the cervical mucus to make it difficult for sperm to pass, and thins the uterine lining to prevent a fertilized egg from implanting [1.8.2].

Eloine and Yasmin both contain the active ingredients drospirenone and ethinylestradiol. However, Eloine is a lower-dose pill with 0.02 mg of estrogen and a 24/4 day cycle, while Yasmin contains a higher dose of 0.03 mg of estrogen and typically follows a 21/7 day cycle [1.8.5, 1.5.2].

If you are less than 24 hours late taking an active (pink) pill, take it as soon as you remember; you will still be protected. If you are more than 24 hours late, your protection may be reduced, and you should use a backup contraceptive method for 7 days. Always refer to the patient information leaflet for detailed instructions [1.7.3, 1.7.5].

Yes, Eloine is also approved for the treatment of moderate acne and for managing the symptoms of Premenstrual Dysphoric Disorder (PMDD) in women who are also seeking oral contraception [1.2.1, 1.3.4].

Common side effects can include mood swings, headaches, breast pain or tenderness, nausea, and irregular menstrual bleeding or spotting, especially during the first few months of use [1.4.4, 1.4.5].
