symptoms of primary herpes

A

fever, malaise, nausea, vomiting; painful intraoral vesicles on oral mucosa– form ulcers with red haloes; gen gingivitis

5

no

-ci/yclovir

10
Q

what is used to treat herpes labialis

A

otc analgesic medications– dont actually stop virus

11
Q

action of antiviral agents

A

incorporates into the viral DNA within host – premature dna termination – prevents virus from reproducing

12
Q

use of antiviral agents

A

treatment initial and recurrent viral infections(hsv1) or herpes labialis

13
Q

dosage of antiviral agents

A

tablets 200mg every 4 hours for 10 days initially

topical 1/2 inch ribbon to area every 3 hours

14
Q

A

acyclovir

15
Q

virus attacks the body’s immune system, resulting in many life-threatening infections and cancers

A

hiv aids

16
Q

once one has developed aids, the immune system is weakened enough to allow for unusual or prolonged infections

A

hiv/aids

17
Q

these drugs chemically are nucleosides and work by inhibiting the viral enzyme reverse ranscriptase

A

nucleoside reverse transcriptase inhibitors

18
Q

this class inhibits the catalytic reaction of reverse transcriptase that is independent of nucleotide binding

A

nonnucleoside reverse transcriptase inhibitors

19
Q

these drugs suppress viral replication by inhibiting protease, the enzyme responsible for cleaving viral precursor peptides into infective virions

A

protease inhibitors

20
Q

this class interferes with the entry of HIV-1 into hosts(lymphocytes) by inhibiting fusion of the virus and cell membranes

A

fusion inhibitors

21
Q

antiretroviral drugs used for treatment of HIV/AIDS end in what

A

VIR

22
Q

PROTEASE INHIBITORS CAN CAUSE

A

dental pain and taste changes

23
Q

HAART

A

high active antiretroviral therapy

24
Q

using three drug combinations for initial therapy is termed what

A

HAART

25

A

candidiasis and angular chelitis

26
Q

what drugs are used to treat fungal infections

A

azoles and nystatin

27

A

to treat ulcers for hiv patients

31
Q

normal flora in gastro and vaginal tracts

A

candida

32
Q

causes a localized superficial infection that is kept in check by the body; however, in certain circumstances such as immunocompromised hosts, the infection spreads

A

candida

33
