In this article, part two of a two-part series, we summarize informati
on crucial to the evaluation of some of the many new non-HN antivirals
and antifungals for formulary consideration. The comparative spectrum
of antimicrobial activity is reviewed, as are significant differences
in the toxicity and pharmacokinetic profiles between new and older ag
ents. We also provide our assessment of the role of each of these new
agents in the management of selected infectious diseases. Appropriate
use of new broad-spectrum antivirals and, antifungals is crucial to at
tempts to diminish the impact of infections and minimize the emergence
of drug-resistant pathogens.
