Description

Proguanil is a prophylactic antimalarial drug, which works by stopping the malaria parasite, Plasmodium falciparum and Plasmodium vivax, from reproducing once it is in the red blood cells. Proguanil in combination with atovaquone are marked under the brand name malarone, which is indicated for the treatment of acute, uncomplicated P. falciparum malaria and for the prophylaxis of Plasmodium falciparum malaria, including in areas where chloroquine resistance has been reported. Atovaquone and proguanil, interfere with 2 different pathways involved in the biosynthesis of pyrimidines required for nucleic acid replication. Atovaquone is a selective inhibitor of parasite mitochondrial electron transport. Proguanil hydrochloride primarily exerts its effect by means of the metabolite cycloguanil, a dihydrofolate reductase inhibitor. Inhibition of dihydrofolate reductase in the malaria parasite disrupts deoxythymidylate synthesis. Recently were done experiments, which confirmed the hypothesis that proguanil might act on another target than dihydrofolate reductase. In addition, was made conclusion, that effectiveness of malarone was due to the synergism between atovaquone and proguanil and may not require the presence of cycloguanil.

Approved Use

Prevention of Malaria: Atovaquone and proguanil hydrochloride tablets are indicated for the prophylaxis of P. falciparum malaria, including in areas where chloroquine resistance has been reported (see CLINICAL STUDIES). Treatment of Malaria: Atovaquone and proguanil hydrochloride tablets are indicated for the treatment of acute, uncomplicated P. falciparum malaria. Atovaquone and proguanil hydrochloride tablets have been shown to be effective in regions where the drugs chloroquine, halofantrine, mefloquine, and amodiaquine may have unacceptable failure rates, presumably due to drug resistance.

Sample Use Guides

In Vivo Use Guide
The daily dose should be taken at the same time each day with food or a milky drink. In the event of vomiting within 1 hour after dosing, a repeat dose should be taken. Prevention of Malaria: start prophylactic treatment with MALARONE (atovaquone and proguanil hydrochloride) 1 or 2 days before entering a malaria-endemic area and continue daily during the stay and for 7 days after return. Adults: One MALARONE Tablet (adult strength = 250 mg atovaquone/100 mg proguanil hydrochloride) per day. Pediatric Patients: The dosage for prevention of malaria in pediatric patients is based upon body weight. Treatment of Acute Malaria Adults: four malarone tablets (adult strength; total daily dose 1 g atovaquone/400 mg proguanil hydrochloride) as a single daily dose for 3 consecutive days. Pediatric Patients: The dosage for treatment of acute malaria in pediatric patients is based upon body weight.
Route of Administration: Oral
In Vitro Use Guide
Curator's Comment: The in vitro effect of proguanil and its active metabolite cycloguanil on proliferating human blood mononuclear cells was studied. Proguanil had no effect on 14C-thymidine incorporation or on the number of cells. Cycloguanil, in concentrations corresponding to the plasma levels found in clinical practice, blocked the endogenous synthesis of thymidine and decreased the number of mitogen- and antigen-stimulated cells.
