SULFA, short for Surrendered ULFA, refers to former members of the United Liberation Front of Assam that have surrendered to the Indian government.

Sulfonamide (or called sulphonamide,sulfa drugs,sulpha drugs) is the basis of several groups of drugs. The original antibacterial sulfonamides are synthetic antimicrobial agents that contain the sulfonamide group. Some sulfonamides are also devoid of antibacterial activity, e.g., the anticonvulsant sultiame. The sulfonylureas and thiazide diuretics are newer drug groups based on the antibacterial sulfonamides.
