Safety assessment of Yasmin: Real-world adverse event analysis using the FAERS database

Article

Author: Wang, Jiahui ; Wang, Lihong ; Tang, Xiuqin ; Shi, Lingli ; Zhu, Lili ; Xu, Wenting ; Chen, Qingli

BACKGROUND:

This study aimed to elucidate the scope and nature of adverse events (AEs) associated with Yasmin.

METHODS:

Among the 17,035,572 AE reports collected from the Food and Drug Administration Adverse Event Reporting System (FAERS) database between January 2004 and September 2023, 25,949 reports involved Yasmin. The demographic details, clinical outcomes, and sources of reports were extracted, and four algorithms were used to evaluate adverse drug reactions.

RESULTS:

The majority of the AE reports involved females aged 18-45 years. Hospitalization was the most frequently reported serious outcome (46.84 %), with death occurring in 292 patients (1.82 %). The highest number of reports originated from the United States. Adverse reactions spanned across 24 system organ categories (SOCs), and hepatobiliary, vascular, and psychiatric disorders were the most frequently reported AEs. A total of 229 Preferred Terms (PTs) were identified for adverse reactions, with high signal strength observed for conditions such as post-cholecystectomy syndrome. In addition, fear of disease, which has not been previously identified as an AE related to Yasmin, was also identified as a high signal strength side effect.

CONCLUSION:

The findings of the present study underscore the importance of monitoring and identifying potential AEs in patients receiving Yasmin, including those not currently listed in the medication instructions.

Comparing the risk of deep vein thrombosis of two combined oral contraceptives: Norethindrone/ethinyl estradiol and drospirenone/ethinyl estradiol

Article

Author: Stalas, Jennifer ; Bu, Kun ; Sanford, Kathryn ; Vandeventer, Jacob ; Cheng, Feng ; Han, Weiru ; Largmann, Rebekah ; von Bargen, Kevin ; Morris, Robert

Background:

Deep vein thrombosis (DVT) has been reported as an adverse event for patients receiving combined oral contraceptives. Norethindrone/ethinyl estradiol (NET/EE) and drospirenone/ethinyl estradiol (DRSP/EE) are two commonly prescribed combined hormonal oral contraceptive agents used in the United States, differing in their progestin component.

Objective:

The purpose of this study was to determine the association between the progestin component of a combined oral contraceptive and the risk of DVT in patients taking oral contraceptives for birth control using data derived from the FDA Adverse Event Reporting System (FAERS).

Methods:

The risk of DVT was compared between patients that had taken NET/EE with those that had taken the DRSP/EE COC formulation for birth control. In addition, age was assessed as a possible confounder and the outcome severity for those diagnosed with DVT were compared between the two groups. Finally, association rule mining was utilized to identify possible drug-drug interactions that result in elevated DVT risk.

Results:

DVT was the fourth most commonly adverse event reported for patients taking DRSP/EE accounting for 8558 cases and the seventeenth most commonly reported adverse event for NET/EE accounting for 298 cases. Age was found to be a significant confounder for users of DRSP/EE with regards to DVT risk across all age groups assessed: 2040 (ROR = 3.69, 95% CI 3.37-4.04) However, there was only a statistically significant elevated risk in patients over 40 years of age taking NET/EE (ROR = 1.98, 95% CI 1.36-2.88). Patients that had taken DRSP/EE and the corticosteroid prednisone simultaneously had an approximately 3-fold increase in DVT risk (ROR = 2.77, 95% CI 2.43-3.15) relative to individuals that had only taken DRSP/EE.

Conclusion:

Based on this analysis, there is a higher risk of developing DVT when taking DRSP/EE than when taking NET/EE as hormonal contraception. In addition, a possibly significant drug-drug interaction between different COC formulations and prednisone were identified. This interaction may result in elevated DVT risk due to a synergistic impairment of fibrinolysis and a decrease in plasmin production.

Inconsistencies in laboratory investigations of hypertension in a young woman taking ethinylestradiol/drospirenone association

Article

Author: Vroonen, Laurent ; Cavalier, Etienne ; Le Goff, Caroline ; Dufour, Patrice

CASE PRESENTATION:

A 34-year-old woman presented to the emergency department for arterial hypertension. Blood analysis requested by the endocrinologist showed very high level of aldosterone (1805 ng/L, normal values: <264 ng/L) and high level of renin activity (2.8 ng/mL/h, normal values: 0.1-2.0 ng/mL/h). The patient reported the use of Yasmin® (ethinylestradiol 30 µg/drospirenone 3 mg) continuously (without hormone-free week between cycles) as oral contraception. Medical imaging examinations revealed no anomaly in the kidneys and the adrenal glands. On the endocrinologist advice, patient stopped the intake of Yasmin®. Aldosterone and renin levels were measured several times after the discontinuation of the oral contraception and a diminution of these levels was observed with a complete normalization of both levels 26 days after the synthetic hormones discontinuation.

DISCUSSION:

The literature shows that ethynilestradiol/drospirenone association can interfere with the renin-angiotensin-aldosterone system and increase the levels of aldosterone and/or renin. We reported here a clinical case illustrating the significant impact of this medication on the renin-angiotensin-aldosterone axis of a young woman. However, this association is not listed among the drugs interfering with the aldosterone and renin-level measurements.

CONCLUSION:

Considering the data in the literature and our clinical case, we suggest adding drospirenone and the ethinylestradiol/drospirenone association in the list of drugs interfering with aldosterone and renin level determination.

Bayer earnings fall again but pharma sales are healthy

Bayer has posted a decline in earnings and sales for the third quarter this morning, but pharmaceuticals continued to perform well as the German firm’s CropScience unit dragged the figures down. Net income fell 10.1% to 249 million euros, a less dramatic decline than expected by analysts, while group turnover was down 7.0% to 7.39 billion euros. However, sales at Bayer’s healthcare division were up 3.5% to 3.94 billion euros, helped by a favourable currency impact, while pharmaceutical revenues increased 3.0% to 2.55 billion euros. Growth was driven by Betaferon/Betaseron (interferon beta 1b) for multiple sclerosis (283 million euros; -2.7%) and the Yasmin (ethinyl estradiol/drospirenone) contraceptive franchise which climbed 3.9% to 320 million euros. Mirena, the firm’s levonorgestrel-releasing intrauterine contraceptive system, contributed 105 million euros, flat on the like, year-earlier period. The haemophilia agent Kogenate (recombinant antihaemophilic factor), edged up 5.1% to 247 million euros, while Nexavar (sorafenib), which is approved for liver as well as advanced kidney cancer, contributed 161 million euros, up 33.1%. Sales of the hypertension treatment Adalat (nifedipine) were up 4.7% to 155 million euros and the erectile dysfunction drug Levitra (vardenafil) climbed 12.2% to 92 million euros. As for Bayer’s antibiotics, Cipro/Ciprobay (ciprofloxacin) brought in 83 million euros, down 1.2%, while Avelox (moxifloxacin) fell 8.9% to 92 million euros. Chairman Werner Wenning said the group achieved a slight year-on-year increase in underlying profits for the first time this year and said “we are very pleased to have reversed the earnings trend despite the fact that many industries are still suffering from the economic crisis”. He added that Bayer is “still adhering to our ambitious full-year forecast” of 31- 32 billion euros in sales and limiting the decline in earnings before interest, taxes, depreciation and amortisation and special items, to 5%. The company plans to complete its current restructuring programmes by the end of 2009, and estimates the special charges involved in that process will reach 350 million euros, up from a previous estimate of 250 million euros.
