Gantrisin

Generic name: Sulfisoxazole acetyl

Why is Gantrisin prescribed?

Gantrisin is a children's medication prescribed for the treatment of severe, repeated, or long-lasting urinary tract infections. These include pyelonephritis (bacterial kidney inflammation), pyelitis (inflammation of the part of the kidney that drains urine into the ureter), and cystitis (inflammation of the bladder).

This drug is also used to treat bacterial meningitis, and is prescribed as a preventive measure for children who have been exposed to meningitis.

Some middle ear infections are treated with Gantrisin in combination with penicillin or erythromycin.

Toxoplasmosis (parasitic disease transmitted by infected cats, their feces or litter boxes, and by undercooked meat) can be treated with Gantrisin in combination with pyrimethamine.

Malaria that does not respond to the drug chloroquine can be treated with Gantrisin in combination with other drug treatment.

Gantrisin is also used in the treatment of bacterial infections such as trachoma and inclusion conjunctivitis (eye infections), nocardiosis (bacterial disease affecting the lungs, skin, and brain), and chancroid (venereal disease causing enlargement and ulceration of lymph nodes in the groin).
