Proguanil is a medication used to treat malaria. It is often used together with another medication called chloroquine or fansidar. It works by interfering with the growth of malaria parasites in the body. Proguanil is usually taken once a day, either with food or on an empty stomach. It is important to take this medication exactly as prescribed by your doctor.
Proguanil is a medication used to both prevent and treat malaria, a serious illness caused by parasites transmitted through mosquito bites [1]. Here's a breakdown of its key aspects:
Uses:
- Prevention (prophylaxis): Proguanil is particularly useful in areas where chloroquine-resistant malaria is prevalent [1].
- Treatment: It's often combined with other antimalarial medications, like atovaquone, to treat acute, uncomplicated malaria caused by the Plasmodium falciparum parasite [2].
How it Works:
Proguanil belongs to a class of drugs called biguanides. It doesn't directly kill the malaria parasite, but rather hinders its reproduction within red blood cells. It achieves this by inhibiting an enzyme called dihydrofolate reductase, which is crucial for the parasite's folate metabolism and DNA synthesis [2, 4].
Administration:
Proguanil is typically taken by mouth as a tablet [1].
Important Points:
- Proguanil is usually used in combination with another antimalarial medication for optimal effectiveness [1, 2].
- It's not recommended for pregnant women or people with severe kidney problems [1].
- Common side effects include diarrhea, abdominal pain, and headache [1].
