Chloroquine (CQ) then becomes protonated (to CQ 2+), as the digestive vacuole is known to be acidic (pH 4.7); chloroquine then cannot leave by diffusion. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme (or FP) to form the FP-chloroquine complex; this ...
It is now suggested that it is used in combination with other antimalarial drugs to extend its effective usage. Popular drugs based on chloroquine phosphate (also called nivaquine) are Chloroquine FNA, Resochin and Dawaquin. Chloroquine is a 4-aminoquinolone compound with a complicated
Fine-needle aspiration (FNA) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin (23–25 gauge (0.52 to 0.64 mm outer diameter)), hollow needle is inserted into the mass for sampling of cells that, after being stained , are examined under a microscope ( biopsy ).
It is approved in the United States as a treatment and preventive measure against malaria. [6] The combination is considered to be more effective in treating malaria caused by Plasmodium falciparum than that caused by P. vivax, for which chloroquine is considered more effective, though in the absence of a species-specific diagnosis, the sulfadoxine-pyrimethamine combination may be indicated.

Examples include amodiaquine, chloroquine, and hydroxychloroquine. [3] Other uses for the derivatives are: anti-asthmatic, antibacterial, anti-fungal, anti-malarial, antiviral and anti-inflammatory agents. [1] A patent application for 4-aminoquinoline compounds was filed in 2002 and published in 2005. [4]
Chloroquine, proguanil, mefloquine, and doxycycline are suppressive prophylactics. This means that they are only effective at killing the malaria parasite once it has entered the erythrocytic stage (blood stage) of its life cycle, and therefore have no effect until the liver stage is complete.
Primaquine is a medication used to treat and prevent malaria and to treat Pneumocystis pneumonia. [2] Specifically it is used for malaria due to Plasmodium vivax and Plasmodium ovale along with other medications and for prevention if other options cannot be used. [2]
