Clinical studies and serum levels on tobramycin (TOB) using intravenous drip infusion were carried out and the following results were obtained. 1. Clinical results Nineteen patients with various infections including 11 respiratory tract infections, 7 urinary tract infections and a wound infection were treated with TOB 20-60 mg b.i.d. and t.i.d. by intravenous drip infusion and for 1 hour during 4 to 16 days.
