Levonorgestrel

PURPOSE: The Kyleena™ Satisfaction Study (KYSS) provided the first data on 19.5 mg levonorgestrel-releasing intrauterine system (LNG-IUS-19.5 mg) use in routine clinical practice. Here we report results from the German participants in KYSS. METHODS: This prospective, observational, single-arm cohort study recruited women who independently chose to use LNG-IUS-19.5 mg during routine counseling in Germany. Overall satisfaction and bleeding profile satisfaction, continuation rates, and safety profile were evaluated at 12 months or premature end of observation (EoO)...

Abnormal uterine bleeding is a frequent symptom in the perimenopause. Causes are numerous, ranging from physiological reactions due to decreasing/unstable ovarian function to premalignant and malignant conditions. Benign findings such as endometrial polyps and myomas increase with age, leading to more abnormal uterine bleeding in the perimenopause. Cervical and vaginal causes of abnormal uterine bleeding should be excluded by speculum examination. Sexually transmitted diseases or pregnancy should be ruled out...

Endometriosis stands out as the predominant issue among gynecological disorders. Approximately 50% of women experiencing infertility have been observed to be affected by endometriosis. Growing evidence indicates that endometriomas, in isolation, might adversely affect ovarian physiology. Medications such as ethinyl estradiol and levonorgestrel have been found to contribute to the amelioration of ovarian cysts in women of reproductive age. Presently, there are limited alternatives available for addressing the infertility associated with endometriosis...

Abnormal uterine bleeding is a common and bothersome symptom in people using hormonal contraception, and it can lead to discontinuation of reliable methods of contraception and unintended pregnancies. Clinicians should counsel individuals about the potential for abnormal bleeding at initiation of the contraceptive method. After considering and excluding other potential causes of abnormal uterine bleeding, clinicians can offer treatment options specific to each hormonal contraceptive method. This article includes algorithms to help clinicians treat abnormal uterine bleeding in people using levonorgestrel intrauterine devices, depo-medroxyprogesterone acetate, progestin implant, progestin-only pills, and combined hormonal contraception...

Estradiol and progesterone potentiate and attenuate reward processes, respectively. Despite these well-characterized effects, there is minimal research on the effects of synthetic estrogens (e.g., ethinyl estradiol, or EE) and progestins (e.g., levonorgestrel, or LEVO) contained in clinically-utilized hormonal contraceptives. The present study characterized the separate effects of repeated exposure to EE or LEVO on responding maintained by a reinforcing visual stimulus. Forty ovary-intact female Sprague-Dawley rats received either sesame oil vehicle (n = 16), 0...

INTRODUCTION: Our objective was to conduct a systematic review and meta-analysis of studies evaluating the oncological and reproductive outcomes of patients with endometrial atypical hyperplasia (AH) and endometrioid endometrial cancer (EEC) undergoing conservative therapy with hysteroscopic resection (HR). MATERIAL AND METHODS: This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for systematic reviews and meta-analyses...

OBJECTIVE: To estimate the rate of breast cancer associated with use of vaginal oestradiol tablets according to duration and intensity of their use. DESIGN: Registry based, case-control study, nested in a nationwide cohort. SETTING: Based in Denmark using the civil registration system, the national registry of medicinal product statistics, the Danish cancer registry, the Danish birth registry, and statistics Denmark. PARTICIPANTS: Women aged 50-60 years in year 2000 or turning 50 years during the study period of 1 January 2000 to 31 December 2018 were included...

BACKGROUND: Currently, there is no evidence-based hormonal treatment for migraine in women. Several small studies suggest a beneficial effect of combined oral contraceptives, but no large randomized controlled trial has been performed. As proof of efficacy is lacking and usage may be accompanied by potentially severe side effects, there is a great need for clarity on this topic. METHODS: Women with menstrual migraine (n = 180) are randomly assigned (1:1) to ethinylestradiol/levonorgestrel 30/150 μg or vitamin E 400 IU...

BACKGROUND: Evidence on the sexual and reproductive health and rights (SRHR) of migrants is lacking globally. We describe SRHR healthcare resource use and long-acting reversible contraceptives (LARCs) prescriptions for migrant versus non-migrant women attending primary care in England (2009-2018). METHODS: This population-based observational cohort study, using Clinical Practice Research Datalink (CPRD) GOLD, included females living in England aged 15 to 49. Migration was defined using a validated codelist...

Overview of: Li RHW, Lo SST, Gemzell-Danielsson K, et al. Oral emergency contraception with levonorgestrel plus piroxicam: a randomised double-blind placebo-controlled trial [correction appears in Lancet 2023;402:850]. Lancet 2023;402:851-8.

BACKGROUND: We conducted a systematic review and meta-analysis to examine outcomes of patients with endometrial intraepithelial neoplasia (EIN) treated with oral progestins or levonorgestrel-releasing intrauterine device (LNG-IUD). METHODS: We conducted a systematic review across five databases to examine outcomes of progestational treatment (oral progestins or LNG-IUD) for patients with EIN. The primary outcome was the best complete response (CR) rate within twelve months of primary progestational treatment...

OBJECTIVE: To evaluate gene expression associated with vaginal bleeding in the 52-mg hormonal intrauterine device (IUD) users. MATERIALS AND METHODS: We conducted a prospective study involving 100 women seeking to use the 52-mg hormonal IUD for contraception. We excluded women with a history or current condition of abnormal uterine bleeding and who were unable to attend a 1-year follow up. Women who expelled the device, removed it for reasons unrelated to vaginal bleeding, or were lost to follow up were discontinued...

INTRODUCTION: Jadelle (Levonorgestrel) implant is a long-acting reversible contraceptives which is recommended for post-partum contraceptive device due to their high efficacy, convenience, and cost-effectiveness. The continuation of Jadelle implant prevents unintended pregnancies and maintain healthy spacing between the pregnancies, thus improving maternal and child health outcomes. However, Government has endorsed the long-acting reversible contraceptives as immediate post-partum contraception, the status of Jadelle implant continuity is unknown...

BACKGROUND: Access to emergency contraception is an important consideration in preventing unintended pregnancies. Inconsistent information about emergency contraceptive given to patients at retail pharmacies may limit access. OBJECTIVE: In this study, we aimed to assess pharmacy students' knowledge of oral emergency contraception. METHODS: Students in a Doctor of Pharmacy program completed a confidential survey about their knowledge of and training on oral emergency contraception...

BACKGROUND: Medical management of adenomyosis is an emerging perspective in modern gynecology. Though levonorgestrel intrauterine system (LNG-IUS) and dienogest (DNG) effectively relieve symptoms in adenomyosis, neither has been approved for the same indication. Our study aims to compare the efficacy and safety of these progestins in treating adenomyosis. OBJECTIVE: To study the efficacy and safety of LNG-IUS versus DNG in patients with symptomatic adenomyosis. DESIGN: Open-labeled, parallel, single-centered, randomized clinical trial...

BACKGROUND: The symptom of heavy menstrual bleeding has a significant impact on professional, physical and social functioning. In 2021, results from a randomized controlled trial comparing a 52 mg levonorgestrel-releasing intrauterine system and radiofrequency non-resectoscopic endometrial ablation as treatments for women with heavy menstrual bleeding were published. Both treatment strategies were equally effective in treating heavy menstrual bleeding during a two-year follow-up. However, long-term results are also relevant for both patients and health care providers...

PURPOSE: Midostaurin, approved for treating FLT-3-mutated acute myeloid leukemia and advanced systemic mastocytosis, is metabolized by cytochrome P450 (CYP) 3A4 to two major metabolites, and may inhibit and/or induce CYP3A, CYP2B6, and CYP2C8. Two studies investigated the impact of midostaurin on CYP substrate drugs and oral contraceptives in healthy participants. METHODS: Using sentinel dosing for participants' safety, the effects of midostaurin at steady state following 25-day (Study 1) or 24-day (Study 2) dosing with 50 mg twice daily were evaluated on CYP substrates, midazolam (CYP3A4), bupropion (CYP2B6), and pioglitazone (CYP2C8) in Study 1; and monophasic oral contraceptives (containing ethinylestradiol [EES] and levonorgestrel [LVG]) in Study 2...

OBJECTIVE: To investigate prescription patterns of combined oral contraceptives (COC) among psychotropic drug users compared to non-psychotropic drug users in routine clinical practice in Europe. STUDY DESIGN: A pooled analysis of three large, prospective, multinational cohort studies including women with a new prescription of COC from 12 European countries. We calculated standardized mean differences (SMD) to investigate whether the status of psychotropic drug use (use/no use) or the psychotropic drug class (psycholeptics/psychoanaleptics) is associated with the healthcare professional's choice of a specific type of COC progestin...

Despite the evidence of altered emotion processing in oral contraceptive (OC) users, the impact of hormonal intrauterine devices (IUD) on emotional processing remains unexplored. Our study aimed to investigate how behavioural performance and event-related potentials (ERPs) linked with emotion reactivity and its regulation are associated with hormonal profiles of women using different types of hormonal contraception and naturally cycling women. Women using OCs (n = 25), hormonal IUDs (n = 33), and naturally cycling women in their early follicular (NCF, n = 33) or mid-luteal (NCL, n = 28) phase of the menstrual cycle were instructed to view emotional pictures (neutral, low and high negativity) and use cognitive reappraisal to up- or down-regulate negative emotions, while their electroencephalogram was recorded...
