- Parasite digests blood (hemoglobin)
- As it feeds, it produces a toxic waste called heme.
- Parasite tries to neutralize the toxin
- It normally converts heme into a harmless form.
- Amodiaquine blocks this process
- The drug prevents the parasite from detoxifying the heme.
- Toxic buildup kills the parasite
- The poison accumulates inside the parasite → it dies.
