Newer antibiotics: their place in geriatric care. Part I.

The third-generation cephalosporins offer considerable appeal for treatment of specific life-threatening infections (nosocomial pneumonia, meningitis, urosepsis) in elderly patients when the disorders are caused by aerobic gram-negative bacilli.
