If a virus is non-living and therefore can't be killed, how do antiviral medicines kill a virus?

Viruses: The definition of what is alive or not can be quite dicey. If one defines life as the ability to replicate oneself outside a cell, the viruses are not alive. They often do replicate quite well inside of host cells using its genetic code, either dna or rna, to 'brainwash' the cell into making lots of virus, an acquired genetic disease. Antivirals inhibit the viral replication process. ...Read more

How do antiviral medicines get rid of the virus?

How do antiviral medicines get rid of the virus?

They don't: Most antviral drugs suppress replication of viruses without actually killing them. Examples include herpesviruses and hiv. Hiv therapy stops the virus from infecting new cells, but viral dna is still present in resting CD4 cells, and could create new virus if medications were stopped. That's why we can't yet cure hiv. ...Read more

What are the effects of antiviral drugs?

What are the effects of antiviral drugs?

Depends on the drug: Some antivirals have methods of action that are very specific for a viral enzyme or protein and not people. Many, however, have effects that also cause toxicity in mammalian cells since that is where the virus replicates. Even those that are fairly specific can have side effects. As an example, some HIV drugs like azt (zidovudine) inhibit viral reverse transcriptase that we do not have but are still toxic. ...Read more

Is it a good idea to stock up on antiviral drugs?

Sometimes helpful: If you have recurrent/chronic herpes you need to begin antivirals within 72hrs of first symptoms or you may be using daily doses as prevention. So stocking up could make sense. These antivirals are related to the drug Acyclovir which is very safe.
Other antivirals may not be as safe or may require monitoring. So stocking up would not be wise. Important: always check expiration dates. ...Read more

What antiviral drug prevents the attachment and penetration of HIV into t lymphocytes?

What antiviral drug prevents the attachment and penetration of HIV into t lymphocytes?

HIV Fusion & Entry: In order for the HIV virus to enter CD4+ "Helper" Tcells, HIV glycoproteins gp120 and gp41 interact with the CD4+Tcell receptor and CCR5 and CXCR4 on the CD4+ Tcell. There are two FDA drugs that are either fusion or entry inhibitors. The reason these drugs are important is because some patients become resistant to the other classes and these can be used.

Hi, what are the antiviral drug for dengue virus spesifically the rna-dependant RNA polymerase as the potential target? Thanks

None yet: Dengue fever and its severe form, dengue hemorrhagic fever, have no cure nor vaccine. One path of research is to find a way to use nucleoside analogs to block the viral rna-dependent RNA polymerase (coded by ns5), which copies the viral genetic material. So far, no drug has been approved yet. Not sure if anyone has found and submitted such a drug to the fda (food and drug administration). ...Read more

Can antiviral drugs make the infection to recurr instead of life long immunity? Ex: Chicken pox

Can antiviral drugs make the infection to recurr instead of life long immunity? Ex: Chicken pox

Unlikely: Since exposure chicken pox, the virus is already replicating days before pox are noted. This is ample time for a person's immunity to start making antibodies. Recurrence of cp is more likely to be based on an individual's innate immunity when they first acquire the infection and later health. Rx needs to be started in 24 hours after pox appear, and important if newborn or other health issue. ...Read more

Is there any oral antiviral medication for warts?

Warts: Each night before going to bed soak a cotton ball in apple cider vinegar, apply it to the wart and then hold it in place with a band-aid. Leave it on all night, or if you like, 24 hours a day but change the soaked cotton and band-aid each evening for a week. The wart will swell and may throb as it reacts with the vinegar and then start to turn black within the first two days and in two weeks gone. ...Read more

What ways can we combat hiv's resistance to antiviral medication?

Take meds: Hiv can develop resistance by replicating (multiplying) when there are antiviral drugs present. The way to prevent this is to always maintain high enough drug levels to completely prevent replication. People who take their medications faithfully rarely develop resistance, as long as the drugs are chosen properly. ...Read more

I have shingles. What are the chances of my 3yr old and 17.5mth old getting it? 17.5mth old had 18mth shot today early. I'm on antiviral medication

Depends on situation: Shingles is a re-activation of the chickenpox virus that hibernates in your nerve roots after you had it or the shot. For unknown reasons, it reactivates and causes the localized rash/pain. The blisters do contain virus, which could give your kids chickenpox. If they were vaccinated, that is unlikely. Covering the sores and hand washing prevents spread of the virus. The kids would not get shingles. ...Read more
