🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by interfering with the digestion of hemoglobin by the malaria parasite inside red blood cells. The parasite normally breaks down hemoglobin to obtain amino acids, but quinine blocks this process, leading to the accumulation of toxic heme and other by-products that kill the parasite. It also affects the parasite's membrane and may interfere with its ability to replicate. In addition to its antimalarial action, quinine has effects on skeletal muscle and the cardiovascular system, which explain some of its side effects and its occasional use for leg cramps.
