Proguanil

Proguanil is an antimalarial medication primarily used for the prevention and treatment of malaria, a disease caused by Plasmodium parasites, typically transmitted through the bite of an infected mosquito. Proguanil works by interfering with the replication of the malaria parasite in the body. It is often combined with other antimalarial drugs to enhance its effectiveness. Proguanil is commonly used by travelers to malaria-endemic regions and is also used in the treatment of acute malaria cases.

Uses of Proguanil

• Prevention of malaria in travelers to endemic areas
• Treatment of acute malaria infections caused by Plasmodium falciparum
• Sometimes used in combination with other antimalarial drugs, like atovaquone, for enhanced efficacy

How Proguanil Works

Proguanil works by inhibiting the enzyme dihydrofolate reductase, which is necessary for the malaria parasite to produce essential DNA and other molecules. By disrupting this process, Proguanil prevents the parasite from replicating in the body, helping to control and eliminate the infection. It is particularly effective when used in combination with other antimalarial medications like atovaquone.

Benefits of Proguanil

• Prevents the onset of malaria when used as a prophylactic
• Reduces the severity of acute malaria infections
• Effective against certain strains of malaria-causing parasites
• Can be used in combination with other antimalarial drugs for better outcomes

How to Take Proguanil

Proguanil is typically taken orally in the form of tablets. For malaria prevention, the usual dose is taken daily, starting 1–2 days before travel to a malaria-endemic area and continuing for 7 days after leaving the area. For treatment of malaria, the dose and duration will depend on the severity of the infection and should be prescribed by a healthcare provider. Always follow the prescribed dosage and do not exceed the recommended dose.

Type of Dosage Available

• Oral Tablets

Side Effects of Proguanil
