Spotlight on compounded bioidentical hormones

Background: The role of hormonal replacement therapy in menopause is under debate. The premature closure of the Women's Health Initiative (WHI) study in 2002 is still a source of concern among treating physicians. Objectives: The interest in alternatives to conventional hormone therapy has significantly increased. The adoption of personalized steroid hormone galenic preparations, formulated by compounding pharmacies, has recently spread. Methods: In June 2023, an extensive literature search was conducted by different authors to identify relevant studies in various databases (MEDLINE, Embase, PubMed, and Cochrane). The studies that met the inclusion and exclusion criteria were further analyzed, and relevant data were extracted and analyzed for each paper. Any discrepancies between the investigators were resolved through a consensus approach. Outcomes: The primary outcomes observed included the clinical utility of CBHT. This study reviewed the current evidence on the utility of compounded bioidentical hormones, concluding that improving knowledge and awareness of bioidentical hormones is necessary to consider their use in clinical practice. Conclusion and outlook: These formulations might provide effective options to best tailor therapies to each patient.
