Safety and efficacy of compounded bioidentical hormone therapy (cBHT) in perimenopausal and postmenopausal women: a systematic review and meta-analysis of randomized controlled trials

POESIT recommendations on management of body-identical hormones in menopausal symptoms

Many women seek treatment to improve menopausal vasomotor symptoms (VMS). The selection of women most likely to benefit from menopause hormone therapy (MHT) is crucial in clinical practice. There is general agreement that women younger than 60 years or who initiate MHT within the first 10 years of menopause, with no contraindications, have greater benefits considering symptomatic relief and additional advantages. This group may have the advantage of protection from osteoporosis and from other chronic diseases that affect postmenopausal women, namely cardiovascular disease (CVD). Cumulating evidence supports MHT for symptomatic women. However, inadequate use according to the needs of symptomatic women led to a burden of suffering worldwide. In recent years, the emergent use of non-regulated body-identical hormones (non-rBHT) can expose patients to potential harms. These hormone preparations are not regulated through the same tests of safety, efficacy or dosing consistency as regulated-BHT (r-BHT). The POESIT (Portugal + Spain + Italy) recommendations highlight the use of 17β-estradiol (E2) and micronized progesterone (P4) as the real r-BHT. In addition, the group emphasizes as an example the data from the REPLENISH study with 1 mg E2/100 mg P4. The combination of the two hormones in one convenient pill showed a clear reduction or elimination of hot flashes and an improvement in sleep quality and, consequently, quality of life. At the same time, this combination has shown high rates of amenorrhea and no significant impact on lipid, glucose or coagulation parameters. Both the REPLENISH study and a real-life retrospective study pointed to the possibility of a lower risk of venous thromboembolism (VTE) with this formulation than with other combinations.

Counseling in menopausal women: How to address the benefits and risks of menopause hormone therapy. A FIGO position paper

Menopause marks the end of menstrual cyclicity and, depending on individual vulnerability, has several consequences related to gonadal steroid deprivation, especially if it is premature. Menopause may be more burdensome for some women than for others. Individual factors, such as personal history, socioeconomic status, ethnicity, and current health conditions, affect symptomatology and, thereby, the menopausal experience. In addition, some menopausal symptoms, such as severe hot flashes, sleep disorders, and depression, are markers of future health risks. Counseling is a fundamental part of health care in the peri- and postmenopause periods. It must include an assessment of the patient's symptoms, needs, desires, and risk profile to address the benefits and risks of menopausal hormone therapy (MHT) on an individual basis and promote a healthy lifestyle. Indeed, healthcare practitioners can and must protect the health and lives of mid-life women by increasing awareness of menopausal symptoms and ensuring healthcare options, especially MHT. The type and duration of MHT should be tailored based on the patient's history, menopausal age, physical characteristics, and current health status so that the benefits always outweigh the risks. This FIGO position paper focuses on the benefits and risks of MHT on health domains, target organs, and systems, and on systemic and vaginal MHT regimens, to provide indications that can be used in the clinical practice for menopausal counseling. Moreover, it offers insights into what FIGO considers the mainstay for the healthcare management of women in peri- and postmenopause, worldwide.

Compounded Bioidentical Menopausal Hormone Therapy: ACOG Clinical Consensus No. 6

SUMMARY

Many compounding pharmacies use the phrase "bioidentical hormone" as a marketing term to imply that these preparations are natural and, thus, safer and more effective than U.S. Food and Drug Administration (FDA)-approved menopausal medications that use bioidentical or synthetic hormones or both. However, evidence to support marketing claims of safety and effectiveness is lacking. Compounded bioidentical menopausal hormone therapy should not be prescribed routinely when FDA-approved formulations exist. Clinicians should counsel patients that FDA-approved menopausal hormone therapies are recommended for the management of menopausal symptoms over compounded bioidentical menopausal hormone therapy. If a patient requests the use of compounded bioidentical menopausal hormone therapy, clinicians should educate them on the lack of FDA approval of these preparations and their potential risks and benefits, including the risks specific to compounding. To truly understand the benefits and harms of compounded bioidentical menopausal hormone therapy, high quality placebo-controlled randomized controlled trials with long-term follow-up comparing custom-compounded products with FDA-approved menopausal hormone therapy are needed.

Comparative estrogen exposure from compounded transdermal estradiol creams and Food and Drug Administration-approved transdermal estradiol gels and patches

OBJECTIVE

The aim of this study was to evaluate the amount of estrogen exposure associated with the use of compounded transdermal estradiol (E2) creams and compare it with estrogen exposure associated with the use of Food and Drug Administration (FDA)-approved transdermal E2 patches and gels.

METHODS

This was a retrospective cohort study that used clinical laboratory data collected from January 1, 2016, to December 31, 2019. Participants were first divided into three groups: postmenopausal women on no menopausal hormone therapy (n = 8,720); postmenopausal women using either a transdermal E2 patch, gel, or cream (n = 1,062); and premenopausal women on no hormonal therapy (n = 16,308). The postmenopausal menopausal hormone therapy group was further subdivided by formulation (patch [n = 777], gel [n = 132], or cream [n = 153]) and dose range (low, mid, or high). The Jonckheere-Terpstra trend test was used to determine if there was a dose-dependent trend in urinary E2 with increasing dose of compounded E2 cream (dose categories for E2 cream subanalysis, <0.5 mg [n = 49], ≥0.5-≤1.0 mg [n = 50], ≥1.0-≤1.5 mg [n = 58], and >1.5-≤3.0 mg [n = 46]). Urinary E2 and other characteristics were compared across formulations (within each dose range) using Kruskal-Wallis one-way analysis of variance.

RESULTS

A dose-dependent, ordered trend existed for urinary E2 with increasing doses of compounded E2 cream (urinary E2 medians [ng/mg-Cr], 0.80 for <0.5 mg, 0.73 for ≥0.5-≤1.0 mg, 1.39 for ≥1.0-≤1.5 mg, and 1.74 for >1.5-≤3.0 mg; Jonckheere-Terpstra trend test, P < 0.001). Significant differences in urinary E2 concentrations were observed in all three dose ranges (Kruskal-Wallis one-way analysis of variance, P = 0.013 for low dose, P < 0.001 for mid dose, P = 0.009 for high dose). Comparison of E2 concentrations of compounded creams to E2 concentrations obtained with similar doses of FDA-approved patches and gels showed that the creams had significantly lower values than the patches and gels.

CONCLUSIONS

Estrogen exposure from compounded transdermal E2 creams increases in a dose-dependent manner; however, the amount of estrogen exposure associated with compounded creams is significantly lower than estrogen exposure associated with FDA-approved transdermal E2 patches and gels. Clinicians should be aware of the direction and magnitude of these potential differences in estrogen exposure when encountering women who have either previously used or are currently using compounded E2 creams.

The Effect of Menopause on Antipsychotic Response

Background: It has been hypothesized that, whenever estrogen levels decline, psychosis symptoms in women increase. At menopause, this can happen in two main ways: (a) the loss of estrogen (mainly estradiol) can directly affect central neurotransmission, leading to increase in schizophrenia-related symptoms, and (b) the loss of estrogen can decrease the synthesis of enzymes that metabolize antipsychotic drugs, thus weakening their efficacy. Aims and Methods: The aim of this narrative review was to investigate the second possibility by searching PubMed and ClinicalTrials.gov for studies over the last two decades that investigated the metabolism of antipsychotics and their efficacy before and after menopause in women or that studied systemic and local estrogen level effects on the pharmacokinetics and pharmacodynamics of individual antipsychotic drugs. Results: The evidence suggests that symptom level in women with schizophrenia rises after menopause for many reasons beyond hormones but, importantly, there is an estrogen-dependent loss of efficacy related to antipsychotic treatment. Conclusion: Effective clinical intervention is challenging; nevertheless, several promising routes forward are suggested.
