Mefloquine is an antimalarial medicine.
It works by killing malaria parasites present in the blood. Mefloquine concentrates within the food vacuoles of these parasites and interrupts their ability to digest their food, hence inhibiting their standard growth and replication. This process helps to manage and eradicate the malarial infection.
