The role of pharmacotherapy in the treatment of endometriosis: an update.

INTRODUCTION

Endometriosis is a chronic inflammatory condition affecting ~10% of reproductive-age individuals and contributing significantly to infertility, pain, and reduced quality of life. Since our 2020 review, new pharmacologic strategies, updated guidelines, and advances in clinical trial evidence have reshaped the therapeutic landscape. Effective, patient-centered management is essential to lessen the burden of disease.

AREAS COVERED: This review synthesizes current evidence-based pharmacotherapy for endometriosis, integrating 2022 European Society of Human Reproduction and Embryology recommendations and including a literature review of PubMed, with an emphasis on articles published after 2020. First-line therapies, including NSAIDs, combined oral contraceptives, and progestins such as dienogest, remain central, while GnRH agonists/antagonists and aromatase inhibitors are considered in refractory cases. Recent data highlight add-back therapy to reduce hypoestrogenic side effects. We also review postoperative regimens, fertility-preserving strategies, management in post-hysterectomy and postmenopausal populations, and therapies under investigation - including anti-inflammatory, antifibrotic, angiogenesis-modulating, and microbiome-targeting approaches.

EXPERT OPINION: Hormonal suppression remains the cornerstone of treatment, but novel nonhormonal strategies and advances in precision medicine hold promise for more durable and individualized care. Ongoing clinical trials, artificial intelligence - assisted diagnostics, and fertility-focused pharmacotherapies represent exciting frontiers. Multimodal, patient-tailored approaches will be key to optimizing long-term outcomes in endometriosis management.
