How Does Qualaquin Work?

Qualaquin belongs to a class of drugs called antimalarials. Malaria is a blood infection caused by tiny parasites called Plasmodium. Qualaquin treats malaria by killing the Plasmodium parasites.
Although it is not entirely known how Qualaquin works, it is thought that the medication prevents Plasmodium from using blood glucose for energy and from making proteins and nucleic acid, which are essential for the parasite to live.

Clinical Effects of Qualaquin

The main active ingredient in Qualaquin is quinine. Clinical studies have shown that quinine can cure malaria when given alone or in combination with clindamycin or tetracycline.
In these studies, 80 to 100 percent of people with uncomplicated (mild) malaria were free from infection after receiving quinine for seven days. They remained infection-free for the entire study period (28 days).
