Larbin Oral Drops belongs to the class of medications called 'quinoline' primarily used to treat malaria. Larbin Oral Drops 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. Larbin Oral Drops is not effective against Plasmodium falciparum. Besides this, it also treats amoebiasis (intestinal dysentery) and rheumatic disease (arthritis). 

Larbin Oral Drops 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. Larbin Oral Drops 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.

Larbin Oral Drops should be taken as prescribed by your doctor. The dose of Larbin Oral Drops can vary depending upon your condition and the severity of the infection.

Larbin Oral Drops falls into a group of medicines known as antimalarials, indicated for treating or preventing malaria. Larbin Oral Drops contains chloroquine, which belongs to quinoline. It works by preventing the formation of the nontoxic heme metabolite hemozoin by the parasite. Due to this, the parasite dies from its own toxic by-products released due to haemoglobin's metabolism. Larbin Oral Drops is also indicated for the treatment of rheumatoid arthritis and autoimmune diseases like lupus and intestinal infection caused by amoeba (amoebiasis).

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.
