    A number of compounds — such as the so-called chloroquine-resistance-reversal agents verapamil, desipramine and chlorpheniramine — are capable of specifically enhancing the activity of chloroquine against chloroquine-resistant strains. Their mechanisms of action are unclear, though they appear to work by enhancing chloroquine uptake by the parasite. Causes of resistance 12 3.1 Definition of antimalarial drug resistance 12 3.2 Malaria treatment failure 12 3.3 Mechanisms of antimalarial resistance 12 3.3.1 Chloroquine resistance 12 3.3.2 Antifolate combination drugs 13 3.3.3 Atovaquone 13 3.4 Factors contributing to the spread of resistance 13 3.4.1 Biological influences on resistance 13 The major action of chloroquine is to inhibit the formation of hemozoin Hz from the heme released by the digestion of hemoglobin Hb. The free heme then lyses membranes and leads to parasite death. Chloroquine resistance is due to a decreased accumulation of chloroquine in the food vacuole.

    For all uses of chloroquine: WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Do not start, stop, or change the dose of any drug without checking with your doctor.

    There has been long-standing interest in targeting pro-survival autophagy as a combinational cancer therapeutic strategy. Clinical trials are in progress testing chloroquine CQ or its derivatives in combination with chemo- or radiotherapy for solid and haematological cancers. Resistance is conferred by mutations in the Chloroquine Resistance Transporter PfCRT, an integral membrane protein localized to the parasite’s internal digestive vacuole. Its mechanism of action is unknown; however, malarial parasites invade human red blood cells, and chloroquine may prevent malarial parasites from breaking down metabolizing hemoglobin in human red blood cells.
