Title

Spironolactone for Adult Female Acne: A pragmatic multicentre double-blind randomised superiority trial to investigate the clinical and cost-effectiveness of spironolactone for moderate or severe persistent acne in women

Description

Spironolactone is a potassium-sparing diuretic that is widely used in the UK for indications including hypertension. It has been used off-license in acne affecting women for over 30 years due to its anti-androgenic properties, although there is little evidence of its benefit. If shown to be effective, spironolactone could reduce the use of antibiotics for acne, be cost-effective and would be more suitable for long-term use than other second line treatments in women.

The SAFA trial seeks to answer the research question: Is oral spironolactone plus standard topical therapy superior to placebo plus standard topical therapy, at improving acne-related quality of life in adult women with moderate-severe persistent facial acne?
