What is acyclovir and valacyclovir used for?
Acyclovir and Valacyclovir are similar drugs used to treat herpes infections. They are so similar that valacyclovir is considered a prodrug of acyclovir. In other words, valacyclovir is converted into acyclovir in the body. Both medications are categorized in a class of drugs called antivirals.
Does acyclovir work better than Valtrex?
Valacyclovir (Valtrex) and acyclovir (Zovirax) are antiviral drugs that work by interfering with viral DNA replication. Both drugs target the same viruses but valacyclovir provides longer duration of action, therefore, doses can be taken fewer times every day – this is the only real advantage.
Why does acyclovir not work for Covid 19?
“Coronaviruses are pretty tricky,” Seley-Radtke says. Simple nucleotide mimics like acyclovir won’t work, because these viruses have another protein that acts as an editor, monitoring the polymerase’s work, recognizing the decoy and cutting it out.
How much acyclovir should I take during an outbreak?
For prevention of recurrent outbreaks of genital herpes infections: Adults and children 12 years of age and older—200 to 400 mg two to five times a day for five days or up to twelve months, depending on how often your outbreaks of infection occur.
Is acyclovir hard on your liver?
Acyclovir is metabolized intracellularly in viral infected cells and is minimally metabolized by the liver. Acyclovir is excreted largely unchanged by the kidneys, perhaps accounting for the absence or rarity of hepatic injury.
¿Cómo se elimina el aciclovir en las células infectadas?
El aciclovir no se une a las proteínas plasmáticas (sólo alrededor del 15%).4 Metabolismo y Eliminación Después de la absorción intracelular, es convertido en monofosfato de aciclovir por la timidina quinasa viralmente codificada; este paso no se produce en un grado significativo en las células no infectadas.
¿Qué son los antivirales clásicos?

¿Qué es el aciclovir trifosfato?
El aciclovir trifosfato, que actúa como un análogo de desoxiguanosina trifosfato (dGTP), inhibe competitivamente la ADN polimerasa viral; incorporación de trifosfato de aciclovir en los resultados de ADN en terminación de la cadena debido a la ausencia de un grupo hidroxilo 3 ‘evita la fijación de nucleósidos adicionales.
¿Qué son los antirretrovirales?
Los antirretrovirales son un grupo creciente de fármacos que inhiben la “replicación” del VIH por distintos mecanismos. Usados en distintas combinaciones, han aumentado la supervivencia de los enfermos de forma espectacular. El Foscarnet (ácido fosfonofórmico) actúa tanto contra el VIH como contra el virus del herpes simple y el citomegalovirus
