🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Quinine, the active ingredient in this medicine, is a cinchona alkaloid that exerts its antimalarial effect by accumulating in the acidic food vacuole of the malaria parasite. It inhibits the heme polymerase enzyme, preventing the conversion of toxic heme into inert hemozoin. This leads to the accumulation of free heme, which is toxic to the parasite and causes its death. Additionally, quinine may interfere with the parasite's ability to transport and utilize nutrients, further contributing to its antimalarial activity.
