  5. acyclovir (Zovirax)
    • synthetic nucleotide, interferes w/ DNA synth of Herpes I,II & zoster (inhibiting viral replication)
    • nephrotox-fever chills flank p. dysuria >freq & urg.
    • neuro- agitation, tremors

    • rifampin- discolored body fluid (red, orange)
  9. Isoniazid
    • Latent TB
    • 6 mo min, 9 mo recommended
  10. Reverse Transcriptase inhibitors
    • RTIs block reverse transcriptase's enzymatic function and prevent completion of synthesis of the double-stranded viral DNA, thus preventing HIV from multiplying.
    • AZT, Retrovir
  11. Protease Inhibitors
    • prevent viral replication by inhibiting the activity of proteases, e.g. HIV-1 protease, enzymes used by the viruses to cleave nascent proteins for final assembly of new virions.
    • Most effective
    • Kaletra
  12. Fusion Inhibitors
    • interferes with the binding, fusion and entry of an HIV virion to a human cell. By blocking this step in HIV's replication cycle, such agents slow the progression from HIV infection to AIDS
