Estradiol valerate 1mg / Medroxyprogesterone 2.5mg tablets

ContextThis narrative review aims to highlight key learning points from the Women's Health Initiative (WHI) studies, providing a nuanced appraisal of menopausal hormone therapy (MHT) risks and benefits in postmenopausal women.MethodsA structured PubMed search was conducted using MeSH terms and keywords for MHT, bone health, cardiovascular and metabolic disease, cancer (breast, endometrial, ovarian, colorectal), and cognitive outcomes. The search included clinical trials, observational studies, and systematic reviews published in the English language.ResultsWHI data reveal that both combined conjugated equine estrogen-medroxyprogesterone acetate (CEE-MPA) and CEE-only therapy significantly reduce hip, vertebral, and total fracture risk, with further skeletal protection from calcium and vitamin D co-administration. Cardiovascular outcomes are strongly influenced by timing: initiation before age 60 or within 10 years of menopause may confer benefit, while delayed initiation (≥65 years) increases risks of coronary events and stroke, supporting the "window of opportunity" hypothesis. CEE-MPA therapy increases invasive breast cancer incidence (especially in prior users), while estrogen-only therapy is associated with a marginal nonsignificant reduction in breast cancer risk. Both regimens lowered colorectal cancer incidence during active treatment. Early MHT initiation has no effect on cognitive function, whereas late initiation increases dementia risk.ConclusionWHI findings underscore the importance of individualized, time-sensitive MHT use, with benefits and risks shaped by formulation, timing, and patient characteristics. These insights continue to inform evolving clinical practice.

Background and aimMenopausal hormone therapy (MHT) remains a pivotal approach in managing menopausal symptoms; however, its effects on inflammation and cardiovascular risk markers are still under debate. In particular, the combination of medroxyprogesterone acetate (MPA) and conjugated equine estrogens (CEE) has shown variable impacts on inflammatory biomarkers. This systematic review and meta-analysis aimed to synthesize evidence from randomized controlled trials (RCTs) assessing the effects of oral MPA combined with CEE (MPA/CEE) on systemic inflammation in postmenopausal women.MethodsThirteen RCTs (comprising 16 arms) reporting data on inflammatory markers, including C-reactive protein (CRP), fibrinogen, homocysteine, and interleukin-6 (IL-6), were included, with a total sample size of 2,278 participants. A random-effects model was used to calculate pooled weighted mean differences (WMDs) with 95% confidence intervals. Subgroup and sensitivity analyses were performed to explore heterogeneity, and publication bias was assessed using Egger's test and trim-and-fill methods.ResultsMPA/CEE treatment was associated with a significant decrease in CRP levels (WMD = -0.173 mg/dL; 95% CI: -0.25 to -0.10; P ConclusionWhile MPA/CEE therapy significantly reduces CRP and fibrinogen, key inflammatory and cardiovascular risk markers, these findings suggest a notable protective effect of oral MPA/CEE on inflammation, highlighting the need for individualized therapeutic strategies based on patient risk profiles.

PurposeTo comprehensively compare and rank hormone therapy for patients with perimenopausal syndrome.MethodsA comprehensive search was conducted on PubMed, Embase, Cochrane Library, Web of Science, CNKI, VIP, and Wanfang databases from inception to August 20, 2024. The quality of the included randomized controlled trials (RCTs) were measured by the Cochrane risk of bias tool. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) method was applied to grade the quality of evidence in this network meta-analysis. Network plots were depicted to show direct and indirect comparisons of hormone therapy for each outcome. The influences of different hormone therapy on the outcomes were illustrated via forest plots and league tables. Rank probabilities showed the ranking of different administration routes.ResultsSeven studies involving 704 perimenopausal syndrome patients were included. The rank probabilities suggested that oral estradiol (E2) combined with medroxyprogesterone and general health guidance had the highest likelihood to be the optimal therapy for the severity of menopausal syndrome. General health guidance combined with oral E2 was less likely to have a nausea and vomiting, and breast pain.ConclusionOral E2 and medroxyprogesterone or general health guidance combined with oral E2 may be the effective and safe option for the management of perimenopausal syndrome.

The perception that hormonal contraception causes weight gain is a general belief that frequently hinders the initiation and continuation of effective family planning. This narrative review analyses data from Cochrane systematic reviews and recent pharmacogenomic studies to separate patient perception from metabolic reality. Analysis of high-quality data, including Cochrane systematic reviews, indicates that the association between Combined Hormonal Contraceptives (CHCs)-including oral pills, the transdermal patch, and the vaginal ring-and weight gain is not supported by consistent high-quality evidence. Placebo-controlled trials demonstrate that these methods are weight-neutral on average. Perceived weight increases in CHC users are likely mediated in part by fluid retention linked to the estrogenic stimulation of the Renin-Angiotensin-Aldosterone System (RAAS), rather than adipose tissue accumulation. Conversely, Depot Medroxyprogesterone Acetate (DMPA) represents a verified clinical risk for weight gain, showing a demonstrated clinical association with significant fat mass accumulation. Hypothesized biological mechanisms for this increase include hypothalamic appetite stimulation and glucocorticoid-like activity. The etonogestrel implant occupies a complex middle ground. While population-level data suggests weight neutrality, recent exploratory pharmacogenomic research has identified a specific variant in the Estrogen Receptor 1 (ESR1) gene. For the minority of women carrying this variant, the implant may trigger clinically significant weight gain, suggesting a biological basis for their subjective experience despite statistical evidence. Ultimately, the persistence of the weight gain concern is fueled by the nocebo effect and the misattribution of natural age-related weight trajectories to contraceptive use.

ObjectiveThe influence of medroxyprogesterone acetate plus conjugated equine estrogens (MPA/CEE) on apolipoproteins and lipoprotein(a) levels has been vastly studied with inconsistent results. These inconsistencies could be attributed to several factors, such as the characteristics of the included participants and dosage and duration of intervention, among others. This study was conducted to determine the impact of MPA/CEE on the lipoprotein(a) and apolipoprotein concentrations in the postmenopausal women through a systematic review and meta-analysis of randomized controlled trials (RCTs).MethodsA comprehensive search was conducted across multiple databases for relevant RCTs up to April 2025, and a random-effects model was used to conduct a meta-analysis, with results presented as the weighted mean difference (WMD) along with a 95% confidence interval (CI). Subgroup and sensitivity analyses were further conducted to find potential sources of heterogeneity.ResultsThe current meta-analysis included 27 RCTs with 37 study arms. The study results revealed an increase in Apolipoprotein A1 (WMD: 12.42 mg/dL, 95%CI: 9.31, 15.52, P ConclusionsThis meta-analysis indicates that MPA/CEE has a beneficial impact in the levels of atherogenic lipoproteins, which be correlated with a reduction in cardiovascular disease risk.

BackgroundTo date, no meta-analysis has reported on the role of transdermal estrogens combined with Medroxyprogesterone Acetate (MPA) in relation to cardiovascular disease (CVD) risk factors in postmenopausal women. To fill this knowledge gap, a meta-analysis of randomized controlled trials (RCTs) was conducted to assess the effects of transdermal estrogens and MPA on CVD risk factors in postmenopausal women.MethodsA systematic literature search was conducted in major databases including PubMed/Medline, Web of Science, SCOPUS, and Embase, from inception to 12 February 2025. The combination of Medical Subject Headings (MeSH) and non-MeSH keywords was used.ResultsA total of 14 trials were included in the meta-analysis. The combined eligible trials found that transdermal estrogens combined with MPA significantly decreased total cholesterol (TC) (WMD: -13.37 mg/dL, 95% CI: -21.54 to -5.21, p = 0.001), low density lipoprotein cholesterol (LDL-C) (WMD: -12.17 mg/dL, 95% CI: -23.26 to -1.08, p = 0.031), and apolipoprotein B (ApoB) (WMD: -7.26 mg/dL, 95% CI: -11.48 to -3.03, p = 0.001) compared to the control. No statistically significant associations were observed between transdermal estrogens combined with MPA on triglyceride (TG), high density lipoprotein cholesterol (HDL-C), lipoprotein(a) (Lp(a)), and apolipoprotein A1 (ApoAI).ConclusionBased on the results of the current meta-analysis, transdermal estrogens combined with oral MPA administration had a beneficial effect on certain CVD risk factors in postmenopausal women, as evidenced by the significant reductions in TC, LDL-C, and ApoB.
