Used primarily as an antimalarial agent, this chemical works by inhibiting the development of malaria parasites in the liver and red blood cells. It is commonly administered in combination with other antimalarial drugs to prevent infection, especially in travelers visiting regions where malaria is prevalent. Its prophylactic use is effective against Plasmodium falciparum and other plasmodial species. The compound is also active against certain resistant strains when combined with atovaquone, enhancing its efficacy. Additionally, it has been explored for potential synergistic effects in treating opportunistic infections in immunocompromised patients.
