Comparison of multiple-dose regimens of netilmicin in patients with urinary tract infections.

A clinical trial involving forty hospitalized patients with urinary tract infections was conducted to compare the effectiveness and tolerance of four dosage regimens of netilmicin: 1, 2, 3, and 4 mg/kg administered twice daily for 7 or 8 days. Each of the dosages was effective and the first three were equally well tolerated. At 4 mg/kg there was one case of renal dysfunction possibly related to netilmicin therapy. Serum concentrations of the drug measured 1 hour after injection were dose-related, as were those measured 1 hour before administration; no appreciable accumulation occurred with any of the regimens.
