Therapy of serious skin and soft tissue infections with ofloxacin administered by intravenous and oral route.

We evaluated the safety and efficacy of ofloxacin administered both by the intravenous route and orally in 26 men with serious skin and soft tissue infection. Twenty-one patients completed antimicrobial therapy and were fully evaluable. Of these, 18 were judged to be cured, while 3 failed therapy either during or within 2 weeks after completion of therapy. Overall, Staphylococcus aureus was the most commonly isolated pathogen and was found to be susceptible to ofloxacin in 12 of 14 patients. Two patients, 1 with a tolerant isolate of S. aureus, the other patient with a resistant isolate of S. aureus, responded clinically to ofloxacin therapy; a third patient with an initially ofloxacin-sensitive isolate failed therapy, and on subsequent culture an ofloxacin-resistant S. aureus was isolated. Ofloxacin was well tolerated and efficacious in the treatment of skin and soft tissue infections including those caused by staphylococci and streptococci.
