Abstract
AIM Drospirenone (DRSP) is a synthetic progestogen approved as a progestin-only pill for contraception in both the United States and Europe. Herein, we conducted a phase I/II study to evaluate the pharmacokinetics, pharmacodynamics, and safety of DRSP in Japanese women. METHODS Single and multiple doses of 4 mg of DRSP were orally administered to healthy premenopausal Japanese women. In the multiple-dose period, 4 mg of DRSP was administered once daily for 24 days. Pharmacokinetics, hormone levels, and adverse events (AEs) were investigated. RESULTS Twelve Japanese women participated in this study. The single- and multiple-dose pharmacokinetics of DRSP was similar to that reported in previous studies in Caucasians. In the multiple-dose period, no subject displayed a progesterone level of more than 5.03 ng/mL. AEs were observed in 11 (91.7%) subjects. The most common AE was genital hemorrhage, which was observed in six (50.0%) subjects, followed by diarrhea and acne in four (33.3%) subjects each. All AEs resolved or improved at the end of the study, and complete recovery was confirmed in all subjects at follow-up. CONCLUSIONS The pharmacokinetics of DRSP in Japanese women was similar to that of previous studies performed in Caucasian women. Repeated administration of DRSP maintained low plasma progesterone levels indicating effective inhibition of ovulation. No notable safety concerns were observed. In this phase I/II study, DRSP had no obvious pharmacokinetic, pharmacodynamic, or safety issues to consider in Japanese women.

Abstract
STUDY OBJECTIVE To evaluate the efficacy and tolerability of a progestin-only pill containing 4 mg drospirenone (DRSP) as a hormonal therapy for the management of endometriosis-associated symptoms in adolescents and young adults Design: Retrospective cohort study METHODS: A retrospective chart review was performed of all adolescents who were prescribed DRSP continuously (without placebo) for treatment of endometriosis at a single pediatric tertiary care center between 2019 and 2022. Electronic medical records were reviewed to obtain demographics and clinical characteristics of the patients. Measured outcomes included symptom resolution and medication discontinuation. The study was deemed IRB exempt. RESULTS A total of 61 patients with endometriosis were prescribed DRSP during the study period, with a median age of 18.9 years (SD 2.3). The majority (97%) were laparoscopically confirmed to have endometriosis, and 85% had stage I disease. Before DRSP use, the most common medications trialed were norethindrone (57%) and norethindrone acetate (68%), and 56% had at least one medical contraindication to receiving estrogen-containing therapy. Of those with follow-up, 52% established an absence of bleeding/spotting, and 67% reported less pain at follow-up. One in four patients discontinued DRSP during the study period, most commonly due to breakthrough bleeding. CONCLUSION DRSP is a well-tolerated and effective option for the treatment of endometriosis-associated symptoms in adolescents and young adults.

Abstract
The most prevalent endocrine and metabolic condition in women of reproductive age are polycystic ovary syndrome (PCOS) with significant risk factors such as circadian rhythm and melatonin disruption. The aim of this study is to assess the effect of vitamin E in combination with a combined oral contraceptive (COC) on continuous light-induced PCOS using hormonal measures, oxidative stress (OS) indicators, and the inhibin beta-A (INHBA) gene, which targets the melatonin protein kinase C (PKC) pathway. An in silico technique anticipated INHBA's binding affinity for vitamin E and COC. For the in vivo investigation (IAEC/240/2021), female SD rats were divided into six groups and subjected to a 16-week induction period, followed by a 2-month test drug treatment with drospirenone (DRSP) as a standard. Serum testosterone, FSH, melatonin, and OS were calculated as hormonal markers. The expression of the INHBA gene was studied to see if it could be linked to the circadian rhythm and OS via the melatonin PKC pathway. According to the in silico study, vitamin E and DRSP had higher binding energy for the INHBA (-8.6 kcal/mol and -8.4 kcal/mol, respectively). When compared to the control group, in vivo results showed a substantial decrease in testosterone levels (p = .05), as well as changes in FSH (p = .78) and melatonin (p = .13). IHNBA gene expression has also dramatically increased, stimulating FSH production in the pituitary gland. Vitamin E and COC concomitantly are beneficial against PCOS because it modulates OS, which in turn influences circadian rhythm and the melatonin PKC pathway.

Abstract
INTRODUCTION Drospirenone/estetrol (DRSP/E4) is a combined oral contraceptive (COC) recently approved in several countries. It is composed of 15 mg of E4, a natural estrogen produced by human fetal liver throughout pregnancy, and 3 mg of DRSP, the first synthetic progestin used in oral contraception derived from 17-α-spirolactone. E4 and DRSP synergistically prevent pregnancy by inhibiting ovulation. E4 differs from 17-β-estradiol or ethinylestradiol because it represents a native estrogen with selective action in tissues (NEST), therefore it displays both agonist and antagonist estrogenic effects in different tissues. AREAS COVERED In this paper, we reviewed the scientific literature published in English prior to April 2023 and gathered information on the pharmacodynamics and pharmacokinetics of DRSP, E4 and their combination for contraception. We also proposed possible clinical applications based on the characteristics of the components of this COC. EXPERT OPINION E4/DRSP-based COC has shown high tolerability, safety and satisfaction and may represent a viable choice in young girls in need of oral contraception and pill users who suffer from high cholesterol, breast tenderness or water retention. Moreover, this new COC shows higher scheduled bleeding rate compared to other pills containing natural estrogens. All the data are reassuring, permitting long-term use.

Abstract
Ethinylestradiol and drospirenone combined oral contraceptive formulations have been marketed for >20 years. Drospirenone has antimineralocorticoid and anti-androgenic effects that may offer several health benefits. Recently, 2 new drospirenone-containing oral contraceptives entered the market, 1 as a progestin-only pill containing 4 mg drospirenone and the other as a combined oral contraceptive containing 15 mg estetrol and 3 mg drospirenone. Estetrol has a unique differential effect on nuclear and membrane estrogen α-receptors when compared with other estrogens, leading to low impact on the liver, breast, and hemostasis parameters and a beneficial effect on the endometrium, vagina, cardiovascular system, bone, and brain. Phase 3 clinical studies demonstrated that the Pearl Index (pregnancies per 100-woman-years) for drospirenone alone is 4.0 in the United States and 0.93 in the European Union and for the estetrol-drospirenone combination it is 2.65 and 0.44, respectively. Drospirenone alone demonstrates high rates of unscheduled bleeding and low rates of scheduled bleeding, whereas the estetrol-drospirenone combination demonstrates a predictable and regular bleeding profile for most users with a high stable rate of scheduled bleeding and a low rate of unscheduled bleeding, reported primarily as spotting only. The adverse event profiles and discontinuation rates owing to adverse events are comparable, and no clinically significant effects were observed on metabolic parameters with either product. Hemostatic assays for drospirenone do not fully evaluate all parameters although the testing that is available suggests negligible effects, whereas validated hemostatic assays demonstrate that the estetrol-drospirenone combination has limited impact on hemostasis. The introduction of 4 mg drospirenone and 15 mg estetrol with 3 mg drospirenone are valuable additions to the contraceptive market. Adding estetrol to 3 mg drospirenone provides advantages of contraceptive efficacy and a regular, predictable bleeding profile with minimal impact on hemostasis parameters.

Abstract
Oral hormonal contraceptive users carry the risk of venous thrombosis and increased mortality. This study aimed to comprehensively profile the serum metabolome of participants using a combination of drospirenone (DRSP) and ethinyl estradiol (EE) containing oral contraceptives (COCs). The MxP Quant 500 kit for liquid chromatography mass tandem spectrometry (LC-MS/MS) was used to analyse the 22 controls and 44 COC users (22 on a low EE dose (DRSP/20EE) and 22 on a higher EE dose (DRSP/30EE)). The kit's results were compared to our internally developed untargeted and targeted metabolomics methods previously applied to this cohort. Of the 630 metabolites included in the method, 277 provided desirable results (consistently detected above their detection limits), and of these, 5 had p-values < 0.05, including betaine, glutamine, cortisol, glycine, and choline. Notably, these variations were observed between the control and COC groups, rather than among the two COC groups. Partial least squares-discriminant analysis revealed 49 compounds with VIP values ≥ 1, including amino acids and their derivatives, ceramides, phosphatidylcholines, and triglycerides, among others. Ten differential compounds were consistent with our previous studies, reinforcing the notion of COCs inducing a prothrombotic state and increased oxidative stress. Although only a limited number of compounds were deemed usable, these were quantified with high reliability and facilitated the identification of meaningful biological differences among the sample groups. In addition to substantiating known drug-induced variations, new hypotheses were also generated.

Abstract
INTRODUCTION Estetrol (E4) is a native estrogen produced only by the fetal liver during pregnancy. E4 is the first new estrogen to be used in hormonal contraception since the introduction of oral contraceptives in 1960. Ethinyl estradiol, the most commonly used estrogen in oral contraceptives today, increases the risks of thromboembolism and has other significant hepatic impacts, which induce important drug-drug interactions. On the other hand, Phase 2 E4 characterization studies demonstrated that E4 has negligible impacts on liver, breast, and vascular endothelium due to its distinct tissue selectivity. Combined with drospirenone (DRSP), E4 offers an improved safety profile for oral contraception. AREAS COVERED This paper briefly highlights the unique pharmacokinetic and pharmacodynamic features of E4. The efficacy, safety, and tolerability results from the Phase 2 and 3 studies of the E4/DRSP pill are discussed to provide the reader with a thorough understanding of E4 and information to use when counseling potential users. EXPERT OPINION The estetrol/drospirenone oral contraceptive is effective and well tolerated and provides good cycle control. In the future, estetrol may be the estrogen of choice if subsequent evidence verifies that it reduces the risks associated with current estrogens, such as venous thromboembolism and drug-drug interactions.

Abstract
Contraceptive tablets typically contain a combination of two synthetic versions of an estrogen and a progestogen, which work together to inhibit the ovulation process. An accurate and precise quantification of these components is essential for contraceptive producers. In this study, we have developed the first gas chromatography-mass spectrometry (GC-MS) method for the simultaneous quantification of 17α-ethinyl estradiol (EE) and drospirenone (DP) in contraceptive formulations. Under the final working conditions, analytes were extracted from the solid by ultrasound-assisted extraction (15 min) in methanol. The resulting suspension was diluted in ethyl acetate, subjected to centrifugation and, finally, the supernatant was directly injected into the GC-MS system. No derivatization reagents were utilized. To correct for instrumental variations, calibration was performed using the internal standard method, with cholesterol as the internal standard. A good linearity was achieved throughout the calibration range for both EE (3-12 µg mL-1) and DP (300-1200 µg mL-1), with R2 values exceeding 0.99. Trueness, assessed in terms of percentages of recovery, was also found to be satisfactory for both analytes, with recovery rates of 106 ± 8% for EE and 93 ± 9% for DP. Furthermore, intra-day and inter-day precision studies yielded relative standard deviation values below 6% for both analytes. In terms of sensitivity, the instrumental limits of detection were 0.25 µg mL-1 for EE and 6.6 µg mL-1 for DP, and the instrumental limits of quantification 0.82 µg mL-1 for EE and 22 µg mL-1 for DP. The method was successfully applied to the analysis of contraceptive tablets from three different pharmaceutical companies. No differences were observed between the measured and the declared amount of active principle per tablet, demonstrating the applicability of the procedure. In addition, a stability study conducted on both the standards and sample extracts demonstrated that they can be stored at room temperature for a minimum period of seven days.

Abstract
The spironolactone derivative drospirenone is combined with ethinylestradiol or estetrol in combined oral contraceptives. Formulations with 17-β-estradiol are used to treat climacteric symptoms. A drospirenone-only formulation has been introduced for contraception. Here, the pharmacological properties of drospirenone, the impact of the different formulations on metabolic and laboratory parameters, and the resulting clinical implications are reviewed. Ethinylestradiol, an inhibitor of CYP metabolic enzymes, changes the pharmacokinetics of drospirenone, leading to a higher drospirenone exposure with ethinylestradiol/drospirenone compared to the drospirenone-only preparation. In addition, several metabolic alterations have been described. The impact of estetrol is less pronounced, and for 17-β-estradiol/drospirenone and drospirenone-only, decreased triglyceride and cholesterol levels were observed. Ethinylestradiol induces various pro-coagulatory factors, leading to hypercoagulability. The effect is significantly reduced with estetrol, and no influence was observed with the drospirenone-only preparation. The anti-mineralocorticoid activity of drospirenone seems to positively counteract the renin-angiotensin-aldosterone-system-activating action of ethinylestradiol. There is no influence on blood pressure with ethinylestradiol/drospirenone and estetrol/drospirenone formulations, while in clinical trials, a reduction has been observed with 17-β-estradiol/drospirenone and drospirenone-only. Anti-aldosterone activity via non-renal mineralocorticoid receptors is associated with cardiovascular health, while interactions with parathyroid hormone signaling impact bone structure and vascular calcification. Though the clinical relevance is unclear for drospirenone, data in this context are reviewed. To sum up, the advantages of drospirenone in hormonal contraception and treatment of menopausal symptoms have been demonstrated for all the formulations described here. Combination with estrogen confers benefits and risks, which must be considered.

Abstract
OBJECTIVE To compare the impact on thrombin generation of the new combined oral contraceptive containing 15 mg estetrol and 3 mg drospirenone with ethinylestradiol (30 or 20 mcg) associated either with 150 mcg levonorgestrel or with 3 mg drospirenone. METHODS Data were collected from the "E4/DRSP Endocrine Function, Metabolic Control and Hemostasis Study" (NCT02957630). Overall, the per-protocol set population included 24 subjects in the ethinylestradiol/levonorgestrel arm, 28 subjects in the ethinylestradiol/drospirenone arm, and 34 subjects in the estetrol/drospirenone arm. Thrombograms and thrombin generation parameters (lag time, peak, time to peak, endogenous thrombin potential, and mean velocity rate index) were extracted for each subject at baseline and after 6 cycles of treatment. RESULTS After 6 cycles of treatment, ethinylestradiol-containing products arms show a mean thrombogram outside the upper limit of the reference range, that is the 97.5th percentile of all baseline thrombograms. On the other hand, the mean thrombogram of estetrol/drospirenone is within this reference interval. After 6 cycles of treatment, all thrombin generation parameters are statistically less affected by estetrol/drospirenone than ethinylestradiol-containing products. CONCLUSIONS In conclusion, an association of 15 mg estetrol with 3 mg drospirenone does not have an impact on thrombin generation compared with ethinylestradiol-containing products that, either associated with levonorgestrel or drospirenone, are able to increase the production of procoagulant factors and decrease the production of anticoagulant ones, shifting the patient to a prothrombotic state. Ethinylestradiol-containing products thus generate prothrombotic environments contrary to estetrol which demonstrates a neutral profile on hemostasis.

Abstract
PURPOSE Despite considerable advances in recently developed combined oral contraceptives (COCs), resulting in lower rates of adverse events while maintaining contraceptive efficacy, there is interest in further innovation. MATERIALS AND METHODS Estetrol (E4), a native oestrogen, and progestin drospirenone (DRSP) were combined in a new COC. A European expert panel reviewed the pharmacology, efficacy, and safety and tolerability of this combination. Their findings are presented as a narrative review. RESULTS E4 15mg/DRSP 3 mg in a 24/4 regimen provided effective contraception with good cycle control, characterised by a predictable regular bleeding pattern and minimal unscheduled bleeding, together with a good safety profile. The combination was associated with high user satisfaction, wellbeing, and minimal changes in body weight. The effects on endocrine and metabolic parameters were limited, and the combination was found to have a limited impact on liver function and lipid and carbohydrate metabolism. Moreover, its effect on several haemostatic parameters was lower than that of comparators containing ethinyl oestradiol (EE) 20mg/DRSP 3 mg and EE 30mg/levonorgestrel 150mg. CONCLUSION E4 15 mg/DRSP 3 mg provides safe and effective contraception, with high user satisfaction and predictable bleeding. Further research will evaluate the long-term safety of the COC.

Abstract
Bleeding irregularities are one of the major reasons for discontinuation of oral contraceptives (OCs), and therefore clinicians need to set expectations during consultations. In this review we provide an overview of bleeding data of recently marketed cyclic combined OCs (COCs) and one progestin-only pill (POP). We evaluated data from phase 3 trials (≥12 months) used to gain regulatory approval. Overall, each type of OC has its own specific bleeding pattern. These patterns however were assessed by using different bleeding definitions, which hampers comparisons between products. In COCs, the estrogen balances the effects of the progestin on the endometrium, resulting in a regular bleeding pattern. However, this balance seems lost if a too low dose of ethinylestradiol (EE) (e.g., 10 µg in EE/norethindrone acetate 1 mg) is used in an attempt to lower the risk of venous thromboembolism. Replacement of EE by 17β-estradiol (E2) or E2 valerate could lead to suboptimal bleeding profile due to destabilization of the endometrium. Replacement of EE with estetrol (E4) 15 mg in the combination with drospirenone (DRSP) 3 mg is associated with a predictable and regular scheduled bleeding profile, while the POP containing DRSP 4 mg in a 24/4 regimen is associated with a higher rate of unscheduled and absence of scheduled bleeding than combined products.

Abstract
The present study aimed to evaluate the effects of 2 mg drospirenone (DRSP) and 1 mg 17β-estradiol (E2) hormone therapy (HT) in combination with rehabilitation therapy for postmenopausal women with Meniere's disease (MD). The combined drug hormone treatment was denoted as DRSP/E2. A total of 65 postmenopausal female patients with MD and severe distress were enrolled in the present prospective study. A total of 31 women comprised the study group (group A), undergoing HT and rehabilitation therapy, whereas 34 women who opted for rehabilitation therapy alone comprised the control group (group B). Vestibular function and distress associated with MD were assessed by stabilometry and the Dizziness Handicap Inventory (DHI) questionnaire, respectively. The data were collected at baseline and during the 3- and 6-month follow-up visits. The areas of the stabilometric ellipses exhibited a higher reduction in group A compared with group B with regard to the baseline values at both follow-up assessments (P<0.001). At baseline, both groups exhibited severe self-perceived discomfort, with similar DHI scores of 72.3±3.7 (group A) and 70.6±3.9 (group B; P=0.07). At the 3-month follow-up, both groups underwent a gradual improvement, which was significantly higher in group A (47.5±3.7) compared with in group B (64.2±3.3; P<0.001). At the 6-month follow-up, the DHI scores were improved in group A (43.4±3.4) compared with in group B (58.5±3.1; P<0.001). Therefore, DRSP/E2 HT was effective in reducing the fluid overload, which is characteristic of MD. The findings of the present study demonstrated that integrated therapy based on the administration of DRSP/E2 HT and rehabilitation may be more effective compared with rehabilitation alone for the management of postmenopausal exacerbation of MD.

Abstract
Hormonal contraceptives are an effective and safe method for preventing pregnancy. Progestins used in contraception are either components of combined hormonal contraceptives (tablets, patches or vaginal rings) or are used as a single active ingredient in progestin mono-preparations (the progestin-only pill (POP), implants, intrauterine systems or depot preparations). Progestins are highly effective in long-term contraception when used properly, and have a very good safety profile with very few contraindications. A new oestrogen-free ovulation inhibitor (POP) has recently been authorised in the USA and the EU. This progestin mono-preparation contains 4 mg of drospirenone (DRSP), which has anti-gonadotropic, anti-mineralocorticoidic and anti-androgenic properties. The hormone administration regimen of 24 days followed by a 4-day hormone-free period was chosen to improve bleeding control and to maintain oestradiol concentrations at early follicular-phase levels, preventing oestrogen deficiency. Clinical trials have demonstrated a high contraceptive effectiveness, a very low risk of cardiovascular side effects and a favourable menstrual bleeding pattern. Due to the long half-life of DRSP (30 - 34 hours), the effectiveness of the preparation is maintained even if a woman forgets to take a pill on a single occasion. Studies involving deliberate 24-hour delays in taking a pill have demonstrated that ovulation inhibition is maintained if a single pill is missed. Following a summary of the current status of oestrogen-free contraception, this review article will describe the clinical development programme of the 4 mg DRSP mono-preparation and the resulting data on the effectiveness and safety of this new oestrogen-free oral hormonal contraceptive.

Abstract
OBJECTIVES To assess the contraceptive efficacy, bleeding pattern and safety of a combined oral contraceptive containing estetrol (E4) 15 mg and drospirenone (DRSP) 3 mg. DESIGN Multicenter, open-label, phase 3 trial. SETTING Sixty-nine sites in Europe and Russia. POPULATION Sexually active women aged 18-50 years with regular menstrual cycles and body mass index ≤35 kg/m2 . METHODS E4/DRSP was administered in a 24 active/4 placebo regimen for up to 13 cycles. Visits were scheduled during Cycles 2, 4, 7 and 10 and after completing treatment during which adverse events (AEs) were collected. Participants recorded medication intake, vaginal bleeding/spotting, use of other contraceptive methods and sexual intercourse on a daily diary. MAIN OUTCOME MEASURES Pearl Index (PI) for women 18-35 years (overall and method-failure), bleeding pattern and AEs. RESULTS A total of 1553 women aged 18-50 years, including 1353 from 18 to 35 years old, received the study medication. PI was 0.47 pregnancies/100 woman-years (95% CI 0.15-1.11); method failure PI was 0.29 pregnancies/100 woman-years (95% CI 0.06-0.83). Scheduled bleeding/spotting occurred in 91.9-94.4% of women over Cycles 1 to 12 and lasted a median of 4-5 days per cycle. The percentage of women with unscheduled bleeding/spotting episodes decreased from 23.5% in Cycle 1 to <16% from Cycle 6 onwards. The most common AEs were headache (7.7%), metrorrhagia (5.5%), vaginal haemorrhage (4.8%) and acne (4.2%). One treatment-related serious AE was reported, a lower extremity venous thromboembolism. One-hundred and forty-one (9.1%) women discontinued study participation because of treatment-related adverse events. CONCLUSION E4/DRSP provides effective contraception, a predictable bleeding pattern and a favourable safety profile. TWEETABLE ABSTRACT A phase 3 trial with E4/DRSP shows high contraceptive efficacy, a predictable bleeding pattern and favourable safety profile.

Abstract
Combined hormonal contraceptive methods are one of the most commonly used methods of planned parenthood. They show high contraceptive effectiveness, reasonable cycle control and bring several non-contraceptive benefits. A limitation of the widespread use of combined hormonal contraception is the risk of cardiovascular complications in individuals with specific risk factors. The risk of cardiovascular complications is related to the used estrogen component. Currently, the most common use of estrogen in combined hormonal contraception is ethinyl estradiol and estradiol valerate. The good estrogenic part of combined oral contraceptives is estetrol, a hormone produced exclusively by the fetal liver. Estetrol exhibits a tissue-selective receptor activity. Unlike previously used estrogens, it does not negatively affect the production of liver proteins and blood clotting parameters. Estetrol is not a perspective for combined hormonal contraception only. It is also promising for treating and preventing osteoporosis, hormonal therapy of menopausal syndrome, and vulvovaginal atrophy syndrome.

Abstract
Simple Summary Hormonal treatments, especially those used to treat menopause symptoms are known to increase breast cancer risk. It is thus necessary to identify new formulations with a better benefit/risk profile. The aim of this translational study was to evaluate the breast cancer risk associated with a combination of a natural estrogen named estetrol, with progestogens such as natural progesterone and drospirenone. Since the assessment of breast cancer risk in patients during drug development is not possible given the requirement of long-term studies in large populations, this study provides new evidence that a therapeutic dose of estetrol for menopause treatment or contraception, combined with progesterone or drospirenone, may provide a better benefit/risk profile toward breast cancer risk compared to the hormonal treatments currently available for patients. Abstract Given the unequivocal benefits of menopause hormone therapies (MHT) and combined oral contraceptives (COC), there is a clinical need for new formulations devoid of any risk of breast cancer promotion. Accumulating data from preclinical and clinical studies support that estetrol (E4) is a promising natural estrogen for MHT and COC. Nevertheless, we report here that E4 remains active on the endometrium, even under a dose that is neutral on breast cancer growth and lung metastasis dissemination. This implies that a progestogen should be combined with E4 to protect the endometrium of non-hysterectomized women from hyperplasia and cancer. Through in vivo observations and transcriptomic analyses, our work provides evidence that combining a progestogen to E4 is neutral on breast cancer growth and dissemination, with very limited transcriptional impact. The assessment of breast cancer risk in patients during the development of new MHT or COC is not possible given the requirement of long-term studies in large populations. This translational preclinical research provides new evidence that a therapeutic dose of E4 for MHT or COC, combined with progesterone or drospirenone, may provide a better benefit/risk profile towards breast cancer risk compared to hormonal treatments currently available for patients.

Abstract
Aim: to test effects of estradiol (E2) 1 mg and drospirenone (DRSP) 2 mg in treatment of normal weight menopausal women with typical menopausal symptoms, hyperinsulinism, and grade I hypertension.Material and methods: The participants were 133 menopausal women, mean age 51.82 ± 3.25 years, body mass index (BMI) 24.9 ± 2.6 kg/m2, waist/hip 0.80 ± 0.05, amenorrhoeic period 2.12 ± 2.10 years. All patients were treated with E2 1 mg and DRSP 2 mg during 12 months period. Blood samples were taken at 8 am before and during 12 months of therapy for: glycemia, lipids, hormonal analysis, follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2, testosterone (T), prolactin (PRL), dehydroepiandrosterone sulfate (DHEAS), and sex hormone-binding globulin (SHBG). Oral glucose tolerance test (OGTT) was performed with 75 g glucose in order to assess insulin secretion. All had grade I hypertension 24 h blood pressure monitoring was performed before and after 12 months of therapy.Results: E2/DRSP significantly decreased total cholesterol, low-density lipoprotein (LDL), apolipoprotein B (ApoB), and increased high-density lipoprotein cholesterol (HDL) and apolipoprotein A (ApoA). Insulin area under the curve (AUC) significantly decreased (6586.1 ± 4194.2 vs. 5315.3 ± 2895.0, p < .05) and homeostatic model assessment (HOMA) (3.53 ± 2.18 vs. 3.0 ± 1.8, p < .05). FSH, LH decreased, E2 increased significantly. Of 24 h day blood pressure decreased significantly.Conclusions: E2/DRSP represents suitable therapy for hyperinsulinemic, grade I hypertensive menopausal women with typical symptoms and normal weight.

Abstract
The association between hypercoagulability and use of drospirenone (DRSP) and ethinylestradiol (EE) containing combined oral contraceptives (COCs) is an important clinical concern. We have previously reported that the two formulations of DRSP combined with EE (namely, DRSP/20EE and DRSP/30EE) bring about a prothrombotic state in hemostatic traits of female users. We report here the serum metabolomic changes in the same study cohort in relation to the attendant prothrombotic state induced by COC use, thus offering new insights on the underlying biochemical mechanisms contributing to the altered coagulatory profile with COC use. A total of 78 healthy women participated in this study and were grouped as follows: control group not using oral contraceptives (n = 25), DRSP/20EE group (n = 27), and DRSP/30EE group (n = 26). Untargeted metabolomics revealed changes in amino acid concentrations, particularly a decrease in glycine and an increase in both cysteine and lanthionine in the serum, accompanied by variations in oxidative stress markers in the COC users compared with the controls. Of importance, this study is the first to link specific amino acid variations, serum metabolites, and the oxidative metabolic profile with DRSP/EE use. These molecular changes could be linked to specific biophysical coagulatory alterations observed in the same individuals. These new findings lend evidence on the metabolomic substrates of the prothrombotic state associated with COC use in women and informs future personalized/precision medicine research. Moreover, we underscore the importance of an interdisciplinary approach to evaluate venous thrombotic risk associated with COC use.

Abstract
Objective To compare the bleeding pattern in women using ethinylestradiol 20 mcg/drospirenone 3 mg (EE 20 mcg/DRSP 3 mg) in a 24/4-day cyclic regimen with an extended regimen. Unexpected bleeding/spotting in the extended regimen group was managed by allowing a 4-day hormone-free interval (HFI). Methods This was a randomized, prospective, open-label, multicenter study. Participants (N = 348) were randomized to receive EE 20 mcg/DRSP 3 mg in either an extended regimen (EE/DRSPes group) or a 24/4-day cyclic regimen (EE/DRSP24/4 group) and followed for 168 days. In the EE/DRSPes group, a 4-day HFI was allowed whenever unexpected bleeding/spotting persisted for ≥7 consecutive days. The participants assessed their bleeding daily as “no bleeding,” “spotting,” or “light,” “moderate,” or “heavy” bleeding according to a predefined scale. Results EE/DRSPes group experienced fewer days of bleeding than those using a 24/4 cyclic regimen (P < 0.001). After 168 days, 57.5% of women in the EE/DRSPes group achieved complete amenorrhea (i.e., neither bleeding nor spotting) and 73.9% achieved “no bleeding” (i.e., no bleeding with or without spotting) during the final 28-day interval of the study period. Women in the extended group who instituted the 4-day HFI experienced a 94.1% rate of successful management of unexpected bleeding/spotting. Conclusion The use of EE 20 mcg/DRSP 3 mg in an extended regimen resulted in high rates of amenorrhea and “no bleeding”. Unexpected bleeding/spotting in the EE/DRSPes group could be managed effectively with a 4-day HFI.

Abstract
Compared with nonuse, combined hormonal contraceptives containing estrogen and a progestogen are associated with a roughly 2- to 3-fold increased risk of venous and a 2-fold increased risk of arterial thromboembolism, including stroke and acute myocardial infarction. These events are, however, overall rare among women of reproductive age. Historically, progestin-only pills were not thought to be linked with any thromboembolic risk increase. Therefore, these preparations may be valuable options in women who are ineligible to take combined hormonal contraceptives. Until recently, only progestogens with partial androgenic activities were available. As demonstrated in animal studies, more modern progestogens such as drospirenone with its anti-mineralocorticoid effects may be associated with even more favorable aspects, which have to be clinically demonstrated, however, in future studies.

Abstract
Methods of hormonal contraception are an important tool in the implementation of family planning. Although the primary design of hormonal contraceptives was based on a combination of estrogenic and progestogenic components, the most important component of hormonal contraceptives is the progestin molecule responsible for the anti-gonadotropic effect leading to ovulation inhibition, increased cervical mucus viscosity and endometrial desynchronization. The combination of progestins with estrogens has improved the bleeding profile, but it has increased the risk of cardiovascular complications, particularly deep venous thrombosis and pulmonary embolism, in patients at specific risk. The development of purely progestogenic contraceptives is being conducted to eliminate these cardiovascular risks. A new hormonal contraceptive based on oral drospirenone alone at a daily dose of 4 mg administered in a 24-active tablet + 4 days hormone-free interval shows contraceptive efficacy and bleeding profile consistent with combined hormonal contraceptives and high safety profile as the risk of deep vein thrombosis and pulmonary embolism does not increase according to recent clinical studies. It appears to be a very effective alternative to combination products suitable for a wide range of users.

Abstract
INTRODUCTION Approximately 100 million women currently use combined oral contraceptives. Combined oral contraceptives use is associated with increased risk of venous thromboembolic events and cardiovascular disease. Progestin-only pills do not increase the risk of venous thromboembolic events, stroke and myocardial infarction but are associated with a poor cycle control. A novel estrogen-free pill containing only drospirenone (DRSP) was developed to improve bleeding pattern, tolerability and acceptance without increasing venous thromboembolic events risks in contraception. MATERIAL AND METHODS Two prospective, multicenter Phase III studies in healthy women aged 18-45 years were performed to demonstrate the efficacy and safety of a drospirenone-only pill in a regimen of 24 days of 4 mg of drospirenone tablets followed by 4 days of placebo. A total of 1571 women (14 329 exposure cycles) were analyzed: 713 patients in the 13-cycle study 1 with 7638 exposure cycles and 858 patients in the 9-cycle study 2 with 6691 exposure cycles. The primary endpoint was the overall Pearl index, calculated for each study separately, and for both pooled. As main secondary efficacy endpoint, the "method failure Pearl index" including all pregnancies during "perfect medication cycles" was evaluated. EudraCT registration numbers: 2010-021787-15 & 2011-002396-42. RESULTS Calculations on pooled studies 1 and 2 with 1571 patients gave an overall Pearl index (based on 14 329 cycles) of 0.7258 (95% CI 0.3133 to 1.4301). No single case of deep vein thrombosis or pulmonary embolism and only one case of hyperkalemia were reported. Additional information such as laboratory parameters, body mass index, bodyweight, heart rate and blood pressure showed no statistically significant changes due to the treatment. CONCLUSIONS This is the first report of a new drospirenone-only oral contraceptive providing clinical efficacy similar to combined oral contraceptives, with a good safety profile, and favorable cycle control.

Abstract
Objectives: The aim of this study was to compare changes in body weight in women using a combined oral contraceptive (COC) consisting of 30-μg ethinylestradiol (EE) and 2-mg chlormadinone acetate (CMA) or a COC consisting of 30-μg EE and 3-mg drospirenone (DRSP).Methods: This randomised double-blind controlled trial (ClinicalTrials.gov NCT01608698) was conducted at a university hospital-based clinic in Thailand between June 2012 and September 2015. A total of 102 women were enrolled in the study, 99 of whom were randomised to EE/CMA (n = 45) or EE/DRSP (n = 54). Each participant was treated for six cycles. Body weight and other parameters as well as side effects were recorded at baseline and at the end of the third and sixth cycles of treatment.Results: A significant difference was observed in mean body weight change between the EE/CMA and EE/DRSP groups from both baseline to third cycle (0.51 ± 1.36 kg vs -0.43 ± 1.56 kg; p = .003) and baseline to sixth cycle (1.00 ± 1.84 kg vs -0.20 ± 2.23 kg; p = .013). The mean difference in body mass index and waist circumference had a similar trend to that of the mean difference in body weight. There was no significant difference in side effects between groups.Conclusion: A COC containing 30-µg EE/3-mg DRSP tended to confer a significantly more favourable change in body weight over a 6-month period compared with a COC containing 30-µg EE/2-mg CMA, which was associated with an increase in body weight.

Abstract
Premenstrual Dysphoric Disorder (PMDD) is a severe form of premenstrual syndrome (PMS) affecting up to 7% of reproductive age women. Women with PMDD are of reproductive age; therefore, contraception and treatment of PMDD are important considerations. The disorder as described in the DSM-V is characterized by moderate to severe psychological, behavioral and physical symptoms beginning up to two weeks prior to menses, resolving soon after the onset of menstruation and significantly interfering with daily functioning. PMDD develops in predisposed individuals after they are exposed to progesterone at the time of ovulation. It has been hypothesized that PMDD is in part attributable to luteal phase abnormalities in serotonergic activity and to altered configuration of ℽ-aminobutyric acid subunit A (GABAA) receptors in the brain triggered by the exposure to the neuroactive steroid progesterone metabolite, allopregnanolone (Allo). A large body of evidence suggests that selective serotonin reuptake inhibitors (SSRIs) can be effective in the treatment of PMDD. Combined hormonal contraceptive (CHC) pills, specifically the 20 mcg ethinyl estradiol/3mg drospirenone in a 24/4 extended cycle regimen has been shown to significantly improve the emotional and physical symptoms of PMDD. Other combined monophasic, extended cycle hormonal contraceptive pills with less androgenic progestins may also be helpful, although not well studied. Copper intrauterine devices (IUDs) are recommended for those not seeking hormonal contraceptives. Progestin-only methods including the progestin-only pill (POP), levonorgestrel (LNG) IUD, etonorgestrel implant or depot medroxyprogesterone acetate (DMPA) have the potential to negatively affect mood symptoms for women with or without baseline mood disorders, including PMDD. Careful counseling and close follow-up is recommended for patients with PMDD seeking these contraceptive methods.

Abstract
Background Combined oral contraceptive (COC) use has been associated with an increased risk of insulin resistance (IR) and other adverse cardiovascular events, despite efforts to reduce the dosage and/or progestin type. COC containing drospirenone (DRSP) is an analog of spironolactone, hence its antimineralocorticoid and antiandrogenic characteristics have been deemed beneficial, although the benefits and/or negative outcome of its usage have not been fully elucidated. We therefore hypothesized that COC with DRSP component will not affect glucose regulation and circulating corticosterone. Method Ten-week-old female Wistar rats were divided into three groups: control (CON), ethinylestradiol/drospirenone COC (EE/DRSP)-treated, and ethinylestradiol/levonorgestrel COC (EE/LN)-treated rats. The treatment lasted for 8 weeks. Results Results showed that with the exception of lipid profiles, EE/LN but not EE/DRSP COC treatment affected body weight, glucose tolerance, plasma insulin, corticosterone, (IR), and pancreatic β-cell dysfunction. Conclusion Taken together, the findings showed that the beneficial effect of EE/DRSP could possibly be through the DRSP component. The result also implies that COCs containing DRSP may be a better and safer means of contraception than those with LN with less cardiovascular risks.

Abstract
Venous thrombosis is associated with combined oral contraceptive (COC) use. We investigated the impact of two ethinyl estradiol (EE) and drospirenone (DRSP) containing COCs (3 mg DRSP/20 µg EE and 3 µg DRSP/30 µg EE) on the viscoelasticity of whole blood clots along with the biophysical and biochemical characteristics of erythrocytes. Thromboelastography (TEG) analysis showed a tendency toward a hypercoagulable state in the COCs groups that was more pronounced with higher EE concentrations. Light microscopy and scanning electron microscopy (SEM) showed rouleaux formation of erythrocytes and alterations to the erythrocyte shape for both COC groups, which was attributed to membrane damage. SEM analysis showed spontaneous activation of fibrin and platelets in the COC groups, along with interactions between erythrocytes and platelets and/or fibrin. Confocal microscopy confirmed compromised membrane integrity in the COC groups compared to controls. Global thrombosis test analysis showed increased platelet activation and low thrombolysis in both COC groups when compared to controls. In conclusion, DRSP/EE formulations impact erythrocytes' biophysical and biochemical properties to cause a shift in hemostasis to a prothrombotic state. Although these effects are mostly subclinical the long-term effects and risks involved with the use of these hormones should be considered carefully for each individual.

Abstract
INTRODUCTION Following a historical overview, the ovulation-inhibiting effect of various orally administered estrogen-progestin combinations (combined oral contraceptives [COCs]) are examined for their components alone or in the various combined formulations. Special emphasis is given to products containing natural estrogens. Areas covered: Inhibition of ovulation with progestins alone; estrogens alone; various progestins in combination with ethinyl estradiol; various progestins in combination with natural estrogens (estradiol, estradiol valerate, and estetrol). Expert commentary: The original idea to achieve ovulation blockage through the administration of steroid hormones involved the use a progestogen (both progesterone and its synthetic homologous). The ability of a progestin to inhibit ovulation depends on the type of compound and on its dosage and a difference of more than 20-fold in activity exists between compounds utilized today in COCs. Initially, the estrogenic component was present only because it contaminated the first progestin utilized. It was soon found that an estrogen is necessary for proper cycle control. It was also found that the estrogen acts synergistically in inhibiting ovulation. For almost half a century, most COCs contained ethinyl estradiol. Today, also natural estrogens are being employed. Inhibition of ovulation was complete with all early high dose preparations. Decreasing dosage allowed some ovarian activity to occur, occasionally leading to a mature follicle. Even in this situation, defective corpus luteum formation assured contraceptive protection.

Abstract
Data have demonstrated that COCs, besides offering a satisfactory and safe contraception, offer a variety of non-contraceptive health benefits and therapeutic positive aspects. Many prescribes and users, however, do not realize these positive aspects especially the non-contraceptive health benefits. While the contraceptive use is the primary indication for COC use for most women, these users should be advised in regard of the non-contraceptive benefits when contraception is discussed and prescribed. Using COCs specifically for non-contraceptive indications is an off-label use in many clinical situations (only some exceptions as e.g. acne vulgaris in some countries are allowed clinical entities for the use of these drugs). Therefore, appropriate discussions with the patient regarding this fact should performed and documented by the prescribing physicians. Independent of the off-label situation, COCs containing the newer progestogens dienogest and drospirenone with their antiandrogenic and antimineralocorticoid health benefits play an important role in the management of many diseases and their use should therefore be considered by clinician’s. This review will focus on the effects of these COCs on the endometrium, the skin, the fat tissue and the premenstrual syndrome.

Abstract
There has been much controversy in the scientific literature and lay press about the potential for increased relative risks (RRs) of venous thromboembolism associated with certain contraceptives over others. This commentary reviews the conflicting data on drospirenone's relative venous and arterial risks and summarizes the details of over two billion dollars in litigation surrounding the use of these products. The current legal environment supports litigation focused on small potential RRs, associated with even smaller absolute risks. The absolute risks of venous and arterial thrombotic events in drospirenone users are low and comparable to that of other combined hormonal contraceptives. Women should have access to a wide array of contraceptive choices, including those containing drospirenone.

Abstract
OBJECTIVES The aim of the study was to assess the efficacy for menstrual-related symptoms of an extended flexible regimen of an oral contraceptive pill containing 20 μg ethinylestradiol and 3 mg drospirenone in comparison with a 24/4 d cyclical regimen of the same formulation. METHODS This randomised, non-inferiority, open-label, multicentre study was conducted in women aged 18-39 years. Their menstrual-related symptoms were assessed using the Penn Daily Symptom Rating (DSR17). Participants were randomised to use an extended flexible regimen of 20 μg ethinylestradiol and 3 mg drospirenone (EE/DRSPe.flex), comprising 168 consecutive days with a 4-d hormone-free interval (HFI, allowing for management of unexpected bleeding) or a conventional 24/4 cyclical regimen of the same pill (EE/DRSP24/4). The primary measure of efficacy was the percentage change in DSR17 total score from baseline to cycle 6. The secondary measures of efficacy were the percentage changes in DSR17 total score from baseline after each 28-d interval throughout the entire study and in the scores for individual DSR17 symptoms. RESULTS The primary analysis demonstrated that EE/DRSPe.flex was not inferior to EE/DRSP24/4 (Mean DSR17 score 9.1; 95% confidence interval (CI) - 2.5, 20.6; p = 0.123). Analysis at intervals throughout the entire evaluation period showed greater reduction in DSR17 total score for EE/DRSPe.flex than for the 24/4 regimen (p < 0.001). The decreases in individual scores for the symptoms 'poor coordination' and 'depression/feeling sad/down or blue' were greater for the extended flexible regimen than for the cyclical regimen (p < 0.05). CONCLUSION The extended flexible regimen was not inferior to the 24/4 cyclical regimen in terms of the primary endpoint. It significantly improved symptoms in the interval analysis, and the effects on specific DSR17 symptoms, compared with the cyclical regimen.

Abstract
BACKGROUND The Clyk™ digital pill dispenser helps ensure correct and consistent administration of a flexible extended regimen of the combined oral contraceptive, ethinylestradiol (EE) 20 μg/drospirenone 3 mg (EE/drospirenone ; YAZ(®) Flex Flex), guiding users through the intake cycle and 4-day pill break and providing visible and acoustic daily reminders when pill intake is due. A study showed that the audible alarm function of the dispenser could help reduce the number of missed pills, but it lacked an appropriate "non-dispenser" group for a meaningful assessment of the impact of the dispenser on adherence. This study indirectly assessed the overall effect of the digital dispenser on adherence by comparing data from a treatment with standard blister packaging. MATERIALS AND METHODS One-year adherence data were compared from two similarly designed, Phase III, open-label, randomized trials of EE/drospirenoneFlex. In study 1, women used diary cards to record adherence with EE/drospirenoneFlex dispensed in blister packs (n=640), and in study 2 the dispenser was used with the alarm activated (n=250) or deactivated (n=248) in addition to using diary cards. RESULTS A mean (±SD) of 4.3 (±4.24) missed pills over 1 year were recorded in diary cards among women who dispensed their pills from the blister packages (study 1) compared with 1.0 (±2.4) recorded by the alarm-activated dispenser (study 2). In study 2, a mean of 1.9 (±4.2) missed pills were reported in the diaries over 1 year compared with 4.4 (±9.1) from automatic recording by the dispenser (both arms of study 2), indicating underreporting of missed pills in diary cards vs the digital dispenser. Adjusting for this rate of underreporting, an estimated mean of ten pills were missed over 1 year by women using EE/drospirenoneFlex in blister packs, or ten times more than with the digital dispenser with activated acoustic alarm. CONCLUSION The digital dispenser helps reduce the number of missed pills and increases adherence.

Abstract
Premenstrual syndrome and its most severe form, premenstrual dysphoric disorder (PMDD), are two well-defined clinical entities that affect a considerable number of women. Progesterone metabolites and certain neurotransmitters, such as gamma-aminobutyric acid and serotonin, are involved in the etiology of this condition. Until recently, the only treatment for women with PMDD was psychoactive drugs, such as selective serotonin reuptake inhibitors. Several years ago, there has been evidence of the beneficial role of combined hormonal contraceptives in controlling PMDD symptoms. Oral combined hormonal contraceptives that contain drospirenone in a 24+4-day regimen are the only drugs that have been approved by US Food and Drug Administration for the treatment of PMDD, but there is scientific evidence that other agents, with other formulations and regimens, could also be effective for the treatment of this condition. However, it remains unclear whether the beneficial effect of combined hormonal contraceptives is associated with the type of estrogen or progestogen used or the treatment regimen.

Abstract
BACKGROUND There are limited data to show the levels of prescribing of combined oral contraceptives (COCs) and other hormonal products containing estrogen/progestogen combinations that may be outside the product licence. AIMS To determine the diagnosis/indication recorded at the time of prescription of cyproterone acetate/ethinylestradiol (CPA/EE) and two COCs, levonorgestrel/EE (LNG/EE) and drospirenone/EE (DRSP/EE). DESIGN AND SETTING Retrospective study using a primary care database, The Health Improvement Network (THIN). METHODS Women in THIN aged 12-49 years prescribed CPA/EE, LNG/EE or DRSP/EE in 2002-2010 were identified. Overall use of each product and proportion of new users each year were determined. Among new users, database codes were analysed to infer the reason for prescription. RESULTS The proportion of new users of each product in 2002 and 2010, respectively, were: LNG/EE, 2.03% and 2.40%; CPA/EE, 0.45% and 0.27%; and DRSP/EE, 0.27% and 0.56%. Most new users prescribed CPA/EE had a record of acne (51.0% and 79.2% in 2002 and 2010, respectively) or hirsutism (3.0% and 5.0% in 2002 and 2010, respectively); the proportion of new users with a record only for contraception decreased from 32.9% in 2002 to 8.6% in 2010. Among new users prescribed DRSP/EE or LNG/EE in 2010, 43.2% and 30.8% of women, respectively, did not have a record indicating use for contraception. CONCLUSIONS Adherence to prescribing guidelines for CPA/EE has improved over time. A substantial proportion of women using DRSP/EE or LNG/EE had records for hormone-responsive conditions only, suggesting that many women were prescribed these therapies for non-contraceptive use.

Abstract
AIMS The present study was conducted to investigate the influence of the strong CYP3A4 inhibitor ketoconazole (KTZ) on the pharmacokinetics of drospirenone (DRSP) administered in combination with ethinylestradiol (EE) or estradiol (E2). METHODS This was a randomized, multicentre, open label, one way crossover, fixed sequence study with two parallel treatment arms. A group sequential design allowed terminating the study for futility after first study cohort. About 50 healthy young women were randomized 1 : 1 to 'DRSP/EE' or 'DRSP/E2'. Subjects in the 'DRSP/EE' group received DRSP 3 mg/EE 0.02 mg (YAZ®, Bayer) once daily for 21 to 28 days followed by DRSP 3 mg/EE 0.02 mg once daily plus KTZ 200 mg twice daily for 10 days. Subjects in the 'DRSP/E2' group received DRSP 3 mg/E2 1.5 mg (research combination) once daily for 21 to 28 days followed by DRSP 3 mg/E2 1.5 mg once daily plus KTZ 200 mg twice daily for 10 days. RESULTS Oral co-administration of DRSP/EE or DRSP/E2 and KTZ resulted in an increase in DRSP exposure (AUC(0,24 h)) in both treatment groups: DRSP/EE group: 2.68-fold DRSP increase (90% CI 2.44, 2.95); DRSP/E2 group: 2.30-fold DRSP increase (90% CI 2.08, 2.54). EE and estrone (metabolite of E2) exposures were increased ~1.4-fold whereas E2 exposure was largely unaffected by KTZ co-administration. CONCLUSIONS A moderate pharmacokinetic drug-drug interaction between DRSP and KTZ was demonstrated in this study. No relevant changes of medical concern were detected in the safety data collected in this study.

Abstract
BACKGROUND Epidemiologic studies recently revealed that using drospirenone (DRSP)-containing contraceptives is associated with an increased risk of thrombosis in women. However, the underlying causality is unclear. OBJECTIVE To study the effects of DRSP on coagulation in vitro and the probable mechanisms involved. METHODS First, the effects of DRSP on the activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT) and fibrinogen (FIB) were measured. Then, the effects of DRSP on platelet activation were investigated in response to low levels of collagen, adenosine 5'-diphosphate (ADP), thrombin, U46619, adrenaline and botrocetin/von Willebrand factor (VWF). RESULTS DRSP has no direct effect on APTT, PT, TT, FIB and platelet aggregation induced by low levels of collagen, ADP, thrombin, U46619 or adrenaline. However, DRSP enhances botrocetin/VWF-induced platelet aggregation and VWF receptor glycoprotein Ib-IX-V (GPIb-IX-V)-mediated signaling. This enhancement can be blocked by the progesterone receptor membrane component 1 (PGRMC1) inhibitor AG205, or by the ADP scavenger apyrase and the cyclooxygenase inhibitor indomethacin. CONCLUSIONS Although DRSP did not directly induce platelet activation, it obviously facilitated VWF receptor GPIb-IX-V-mediated platelet activation. The potential DRSP-binding protein PGRMC1 may play a role in this process. Our study also suggested that the inhibition of thromboxane A2 production and the activation of ADP receptors might prevent the side-effects of DRSP.

Abstract
AIM A combined oral contraceptive containing ethinylestradiol 20 µg plus drospirenone 3 mg (EE20 + DRSP) in a 24/4 regimen has been shown to alleviate the symptoms of premenstrual syndrome and premenstrual dysphoric disorder. This study was conducted to evaluate the efficacy of EE20 + DRSP in Japanese patients with premenstrual symptoms. MATERIAL AND METHODS A multicenter, prospective, open-label, single-arm, phase IV study was performed in Japanese women with dysmenorrhea and premenstrual symptoms. They were treated with EE20 + DRSP to alleviate the symptoms of dysmenorrhea for six treatment cycles. Premenstrual symptoms were evaluated using a Premenstrual Symptoms Questionnaire at baseline and after three and six cycles of EE20 + DRSP. The degree of dysmenorrhea was also evaluated using a visual analog scale at baseline and after one, three, and six cycles of EE20 + DRSP. RESULTS Forty-eight patients were treated with EE20 + DRSP. Most of the premenstrual symptoms were alleviated significantly by three and six cycles of EE20 + DRSP treatment. EE20 + DRSP treatment significantly improved the severity of premenstrual symptoms. We also confirmed the effectiveness of EE20 + DRSP for the treatment for dysmenorrhea. CONCLUSION This study showed that EE20 + DRSP could be a useful treatment strategy for premenstrual symptoms in Japanese women.
