Anti infective Drugs II Flashcards
Properties of a virus
Intracellular- do not live outside host
Take over cells genetic material & kill host cell
viruses are spread by
inhalation, ingestion, inoculation
Common viral infections
Smallpox Warts influenza Resp infection HIV/AIDS Hep ABCDE
Viral infection
Latent infection
persists in an inactive form for months/ years
Viral infections
Oncoviruses
viral nucleic acid becomes integrated with host DNA which results in development of cancer
Antiviral MOA
inhibit replication by:
Blockig replication transcription, translation, of viral genetic material
does not destroy existing virus infected cells
Viruses controlled by antiviral medications
Herpes, Varicella zoster
Influenza
Hep ABC
Virus controlled by vaccine
Hep A&B Measles, mumps Tetnus Polio Meningitis
Goal of antivirals
limit the spread of the virus
Protection, symptom contro and reduction
people with a competent immune system have best response
How else can we prevent viral infections
Vaccines Cough etiquette Hand hygiene PPE isolation Harm reduction
Herpes drugs (2)
Acyclovir & Valacyclovir
Herpes Viral Infections are highly transmissible through ____.
contact
Herpes is curable Tor F
F it is not curable
Hereps- Outbreaks occur with periods of latency To F
F latency requires stimulant to present symptoms and can go moths without symptoms
Acyclovir drug is for best taken with
Herpes Simplex Virus
food
Acyclovir drug for herpes will do what for the pt
decrease viral shedding, pain, duration of genital herpes lesions
less itchy, pain, and heal faster
Adverse effect of Acyclovir
N&V, Fatigue, headache< nephrotoxicity, burning on application
Valacyclovir is a drug for
herpes simplex virus
valacyclovir is a oral prep for
recurrent genital herepes and zoster virus
indicated for less serious infection
Antiviral drugs are used to
treat infections caused by viruses other than HIV
Antiretrovial drugs are used to
treat infection caused by HIV just need to know their therapeutic effect not drug profiles
characteristic of Antiviral
Able to enter the cells that are infected with virus
Interfere with viral nucleic acid synthesis or regulation or both
Prevent the fusion process
Some stimulate the body’s immune system
Chemoprophylaxis
administering a drug to prevent a disease
HIV is a _____ virus
retrovirus
a retrovirus is
a virus that enters its RNA to the DNA of a cell changing the genome
Anti- Retroviral Therapy
indicated for treatment ofHIV infection
prophylaxis(prevtnion) for infants/HCP at risk
Why wouldn’t we give Anti- Retroviral Therapy?
intolerance, drug toxicity, drug interactions
What would we teach a pt on Anti Retroviral Therapy
Compliance for success
Drug resistance possibility
life long therapy
when should we assess for adverse effects on anti retroviral drugs
2 times first month and ever 3 months after
Influenza A&B medications
Oseltamivir &
Zanamivir
when should treatment begin with influenza symptom onset
2 days
Indication for Influenza A orB
treating a uncomplicated acute illness in adults
Influenza A&B prevents budding irons from escaping infected cells which would reduce the duration of the illness
Oseltamivir is a medication for?
Influenza A&B
for prophylaxis 3 months or older or any age oral use what medication would be used
Oseltamivir
