Long-term oral treatment of urinary tract infections with single daily doses of a new antibacterial drug combination (Kelfiprim).

Of 30 patients with severe, complicated U.T.I. 27 have been given single daily doses of Kelfiprim (KP), a new sulfatrimethoprim combination, for 8 weeks. In 24 bacteriuria was lastingly controlled, one had a relapse, one had a reinfection, and in one, with bladder carcinoma, bacteriuria persisted. Three other patients received KP for shorter periods, as they presented gastric intolerance or skin hypersensitivity, but in two of them a lasting sterilization of the urine has been obtained. The usefulness of a single daily dose schedule is stressed.
