Spironolactone 100 Mg Tablet contain spironolactone, which is primarily used as a diuretic, to reduce fluid retention in conditions such as congestive heart failure, hypertension (high blood pressure), liver cirrhosis and kidney disease. Spironolactone in Silectone tablets 100mg also acts as an anti-androgen by binding to the androgen receptor and competing with dihydrotestosterone (DHT), the active metabolite of testosterone, which promotes male characteristics, thereby blocking the action of DHT. Boxes of 30 tablets.
