Which drug is first-line treatment for amebic liver abscess?

Treating amebic liver abscess requires a drug that directly kills Entamoeba histolytica within liver tissue. Metronidazole is the standard first-line choice because it is highly active against amebic trophozoites and penetrates liver tissue effectively, leading to rapid symptom and lesion improvement. After the parasite is controlled, a luminal agent (such as paromomycin or diloxanide furoate) is used to eradicate intestinal cysts and prevent relapse. The other options are antibacterial drugs and do not reliably target Entamoeba histolytica, so they aren’t appropriate as first-line therapy for amebic liver abscess.
