Pharmacology

Quinine inhibits nucleic acid synthesis, protein synthesis, and glycolysis in Plasmodium falciparum and can bind with hemozoin in parasitized erythrocytes. However, the precise mechanism of the antimalarial activity of quinine sulfate is not completely understood.

Activity In Vitro and In Vivo

Quinine sulfate acts primarily on the blood schizont form of P. falciparum. It is not gametocidal and has little effect on the sporozoite or pre-erythrocytic forms.

Indications

  • Resistant strains of falciparum malaria,
  • Symptomatic relief of muscle cramps, including nocturnal cramps.
  • Treatment of uncomplicated Plasmodium falciparum malaria.

Contra-indications

Pregnanacy, lactation, tinnitus, optic neuritis, myasthenia gravis.

Quinine Sulphate is also contraindicated in patients with the following:

  • Prolonged QT interval. One case of a fatal ventricular arrhythmia was reported in an elderly patient with a prolonged QT interval at baseline, who received quinine sulfate intravenously for P. falciparum malaria
  • Glucose-6-phosphate dehydrogenase (G6PD) deficiency.
  • Hemolysis can occur in patients with G6PD deficiency receiving quinine.
  • Known hypersensitivity reactions to quinine.
  • Known hypersensitivity to mefloquine or quinidine: cross-sensitivity to quinine has been documented.

These include, but are not limited to, the following:

  • Thrombocytopenia
  • Idiopathic thrombocytopenia purpura (ITP) and Thrombotic thrombocytopenic purpura (TTP)
  • Hemolytic uremic syndrome (HUS)
  • Blackwater fever (acute intravascular hemolysis, hemoglobinuria, and hemoglobinemia)
  • Myasthenia gravis. Quinine has neuromuscular blocking activity, and may exacerbate muscle weakness.
  • Optic neuritis. Quinine may exacerbate active optic neuritis.
