Sulfalene ( INN, USAN) or sulfametopyrazine ( BAN) is a long-acting sulfonamide antibacterial used for the treatment of chronic bronchitis, urinary tract infections and malaria. [2] [3] As of 2014 there were only two countries in which it is currently still marketed: Thailand and Ireland. [3]
It was discovered by researchers at Farmitalia and first published in 1960 and was marketed as Kelfizina. [4] [5]
