GNUR 294 FINAL EXAM
Pharmacotherapy of Non-HIV Viral Infections
Viruses differ from bacteria in the sense they are compromised of a few molecules
Intracellular parasites, present in many places, some very lethal, some can co-exist
The issue with viruses that make them so difficult is because they used the host cell, they are
very difficult to kill
Anti-viral drugs are the least effective
Mutate very rapidly, resistance develops because antiviral medication is geared towards
forms of the virus and it changes so rapidly and the drug becomes ineffective

IV form slowly and hydrated
o Does not kill or cure this virus completely
o Short half lives- given multiple times during the day

Nucleoside Reverse Transcriptase inhibitors
