Abstract:
Long-term administration of acetohydroxamic acid to dogs with experimentally induced urease-positive staphylococcal urinary tract infections and struvite urolithiasis resulted in dose-dependent inhibition of urolith growth or urolith dissolution. Inhibition of urolith growth was associated with drug dose-dependent reduction of urine urease activity, urine pH, crystalluria, pyuria, hematuria, and proteinuria. Lesions of the urinary tract of dogs treated with acetohydroxamic acid were less severe than those of control dogs. Dose-dependent adverse drug reactions included reversible hemolytic anemia, abnormal red cell morphology, and abnormalities of bilirubin metabolism.
