Short-Term, Low-Dose Spironolactone for Treatment of Hyperandrogenic Symptoms of Polycystic Ovary Syndrome-A Systematic Review
Abstract
Objective: Polycystic ovary syndrome (PCOS) is a common condition, that manifests as menstrual irregularities, subfertility, or symptoms of hyperandrogenism - including hirsutism, adult acne, and alopecia. Current pharmacological treatment of the hyperandrogenic symptoms includes the combined oral contraceptive pill. However, there are multiple contraindications and side-effects, which limit their use. Anti-androgens, such as spironolactone, are commonly prescribed off-label but its efficacy in PCOS is uncertain. This review aims to evaluate the efficacy and safety of spironolactone, when compared to other nonhormonal medications in the management of PCOS hyperandrogenic symptoms.
Methods: Comprehensive literature searches were conducted across MEDLINE, EMBASES, PUBMED and SCOPUS. RCTs published in English assessing the use of spironolactone for hyperandrogenism in PCOS were included. The quality of papers was assessed using Cochrane RoB 2.0 tool. Meta-analysis was conducted using a random-effects model, reporting as standardised mean differences and 95% confidence intervals.
Results: Of 3378 studies identified, five open-label RCTs met the inclusion criteria, three of which were included in the meta-analysis. Spironolactone, monotherapy or combination with metformin, showed no statistically significant difference in reducing Ferriman-Gallwey scores, total testosterone levels or BMI compared to metformin monotherapy. Side effects of spironolactone included menstrual…
