    Aralen chloroquine is an antimalarial drug used for the treatment of malaria and extraintestinal amebiasis. Common side effects are reduced hearing, tinnitus, nausea, vomiting, and diarrhea. Dosage, drug interactions, and pregnancy and breastfeeding safety are provided. Hydroxychloroquine has similar pharmacokinetics to chloroquine, with rapid gastrointestinal absorption and elimination by the kidneys. Cytochrome P450 enzymes CYP2D6, 2C8, 3A4 and 3A5 metabolize hydroxychloroquine to N-desethylhydroxychloroquine. Pharmacodynamics. Antimalarials are lipophilic weak bases and easily pass plasma membranes. Elimination Route. Chloroquine and its metabolites slowly excreted by the kidneys; unabsorbed drug is excreted in feces. a Up to 70% of a dose is excreted unchanged in urine and up to 25% of dose may be excreted in urine as desethylchloroquine. a Small amounts of chloroquine may be present in urine for weeks, months.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.
