About EMQUIN DS 500MG TABLET

EMQUIN DS 500MG TABLET belongs to the class of medications called 'quinoline' primarily used to treat malaria. EMQUIN DS 500MG TABLET gives a degree of protection (prophylaxis) against malaria when people travel to areas where malarial cases exist. It is effective against Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae. EMQUIN DS 500MG TABLET is not effective against Plasmodium falciparum. Besides this, it also treats amoebiasis (intestinal dysentery) and rheumatic disease (arthritis).

EMQUIN DS 500MG TABLET contains 'chloroquine' which acts by killing the malarial parasites, i.e. Plasmodium and stops the formation of the nontoxic heme metabolite hemozoin by the parasite. Heme part of the red blood cells is broken by the malarial, causing parasites. EMQUIN DS 500MG TABLET prevents the breakdown of heme part and is actually toxic to the parasite. It kills the parasitic form living in red blood cells that resides in the liver.

Disease/Condition Glossary

Malaria: It is a severe & fatal parasitic infection caused by a protozoan called Plasmodium. 4 types of parasites can infect humans with malaria: Plasmodium falciparum, Plasmodium vivax, Plasmodium ovale, and Plasmodium malaria. Female anopheles mosquito bites cause it. If bitten by an infected mosquito (the Anopheles mosquito), malaria parasites are injected into the blood. These parasites then migrate to the liver where they multiply via the bloodstream. A patient doesn't feel sick at this period because the parasites are in the liver. Then the parasites leave the liver and enter the red blood cells where the parasites are developing, and then the red blood cells burst, allowing them to transfer to another blood cell. The parasites release harmful chemicals into the bloodstream at this point, and the patient begins to feel ill. Malaria leads to periodic fever-chills, anaemia, kidney failure, and jaundice due to excessive red blood cell death due to plasmodium growth inside them.
