Chloroquine given alone is a safer drug than emetine in amoebic liver abscess, but unfortunately the relapse rate is almost 25%. A patient with amebic abscess of the liver was treated with standard doses of metronidazole but remained febrile and pulmonary complications developed.

When treated with combined emetinehydrochloride, chloroquine, andaspiration, the prognosis is excellent in adults Wilmot, 1962, this regime being more successful than treatment with a single drug Wilmot, Powell, and Adams, Until Conan 1948 demonstrated the amrebicidal action of chloroquine in the liver, emetine preparations had an unchallenged and specific place in the treatment of amoebic liver abscess.
