    Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. However, resistance to the drug also rapidly emerged, with the first cases of not being cured by administration of chloroquine being reported in the 1950s.

    Usual Adult Dose for Malaria. 1250 mg orally as a single dose Use For treatment of mild to moderate acute malaria due to mefloquine-susceptible strains of Plasmodium falciparum both chloroquine-susceptible and -resistant strains or P vivax Chloroquine resistance was indicated if schizont maturation occurred in vials containing a chloroquine concentration of 1-5 nmol/ml or more. is Of the 10 P falciparum isolates tested, complete inhibition of schizont formation was found at 0-5 nmol/ml in 2 cases and at 0-75 nmol/ml in 1 case, indicating sensitivity. Chloroquine has long been used in the treatment or prevention of malaria from Plasmodium vivax, P. ovale, and P. malariae, excluding the malaria parasite Plasmodium falciparum, for it started to develop widespread resistance to it. Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence.

    Nowadays, other drugs, and notably ones containing artemisinin-based compounds, are preferentially used to treat uncomplicated malaria and especially in areas where chloroquine resistance is known to occur. Since then, resistance has spread rapidly (since obviously it is beneficial to the parasite to be resistant, so various mutations conferring this protection have arisen multiple times in different areas in the world and also been passed on preferentially to new generations of malaria parasites), and now chloroquine resistant are found in multiple locations in south-east Asia, such as Myanmar and India, as well as from Guyana in South America.

This fear was increased considerably by the discovery of strains of chloroquine-resistant P. falciparum in four countries of Southeast Asia between 19, and it was realized in the autumn of 1965 when the U. S. Army began extensive field operations in Southeast Asia. Shortly after combat units began probing the remote forested areas of the Ia-Drang and Vinh-Thanh Valleys

    In this study we have investigated the digestive vacuole pH of a chloroquine-sensitive and a chloroquine-resistant strain of P. falciparum, using a range of dextran-linked pH-sensitive fluorescent dyes. The estimated digestive vacuole pH varied with the concentration and pKa of the dye, ranging from ∼3.7-6.5. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted. Chloroquine was first discovered in the 1930s in Germany and began to be widely used as an anti-malaria post-World War II, in the late 1940s. However, resistance to the drug also rapidly emerged, with the first cases of Plasmodium falciparum not being cured by administration of chloroquine being reported in the 1950s.
