Acyclovir drug class?

What drug class is acyclovir?

Acyclovir is an antiviral medication in the nucleoside analog class. It is specifically a synthetic analog of the DNA nucleoside deoxyguanosine.

What does that mean for its use?

Because acyclovir is a DNA nucleoside analog, it targets viral DNA replication. Clinically, it is used for infections caused by herpes-family viruses, such as herpes simplex and varicella-zoster.

Is acyclovir the same class as other common antivirals?

Acyclovir belongs to the “acyclic nucleoside analog” group (often grouped with other nucleoside/nucleotide antivirals used against herpes viruses). Related drugs in the same general antiviral strategy include agents like valacyclovir and famciclovir, which are commonly used as alternatives because of different formulations and dosing.

Where would you see this labeled on prescriptions or medical references?

You’ll usually see acyclovir categorized under headings such as “antiviral,” “nucleoside analog,” or “antiherpetic” (reflecting its herpesvirus activity rather than a broad-use antiviral).
