Study Notes
Antiviral Drug Overview
- Antiviral drugs primarily work by stopping viral replication rather than killing the virus directly.
- Antiviral drugs do not alter the host's immune system or are classified as virucidal.
Specific Antiviral Drugs
- Zanamivir (Relenza): Administered only via oral inhalation for influenza treatment.
- Amantadine: Notable for potential severe CNS side effects, including glaucoma exacerbation.
- Ribavirin (Virazole): The only approved treatment for Respiratory Syncytial Virus (RSV).
Patient Care Considerations
- Asymptomatic individuals exposed to the flu may be treated with Flumadine (rimantadine).
- Aerosolized Ribavirin should not be given in the presence of a pregnant visitor due to safety concerns.
- Prior to administering Acyclovir (Zovirax) for genital herpes, inquire about milk allergies due to potential lactose sensitivity.
Allergy and Side Effects
- Anaphylactic responses to antiviral drugs may include swelling of the face or throat.
- When patients report sore throat and fever after taking efavirenz (Sustiva), the immediate action is to hold the dose and notify the prescriber.
Retrovirus Characteristics
- Retroviruses are distinct as they integrate their genetic information into the host cell's DNA.
HIV Education
- Patients with HIV should understand that antiretroviral therapy manages the virus but does not result in a cure.
- Antiretrovirals are essential for limiting the progression of HIV.
- Opportunistic infections arise from the damage to the immune system caused by the virus itself, rather than being direct drug effects.
