QUALAQUIN (quinine sulfate) is an antimalarial drug indicated only for treatment of uncomplicated Plasmodium falciparum malaria. It’s an alkaloid derived from the bark of the cinchona tree and is the active ingredient in extracts of the cinchona that have been used for that purpose since before 1633. Quinine sulfate has been shown to be effective in geographical regions where resistance to chloroquine has been documented. Quinine inhibits nucleic acid synthesis, protein synthesis, and glycolysis in Plasmodium falciparum and can bind with hemazoin in parasitized erythrocytes. However, the precise mechanism of the antimalarial activity of quinine sulfate is not completely understood. It is thought to act by inhibiting heme polymerase, thereby allowing accumulation of its cytotoxic substrate, heme. As a schizonticidal drug, it is less effective and more toxic than chloroquine. Quinine is FDA-approved. It is not considered safe and effective for the treatment or prevention of leg cramps-- an "off-label" (non-FDA-approved) use. Quinine is associated with serious and life-threatening adverse events, including: thrombocytopenia, hypersensitivity reactions, and QT prolongation. Thrombocytopenia associated with the use of quinine for the treatment or prevention of leg cramps includes: immune thrombocytopenic purpura, hemolytic uremic syndrome, thrombotic thrombocytepenic purpura with associated renal insufficiency.
