Application

Atovaquone inhibits the cytochrome bc(1) complex via interactions with the Rieske iron-sulfur protein and cytochrome b in the ubiquinol oxidation pocket. In addition to its use as a treatment for toxoplasmosis, atovaquone has antimalarial properties and prevents pneumocystis pneumonia post-renal transplant.

Biochem/physiol Actions

Atovaquone is an anti-protozoal mitochondrial electron transport inhibitor; Antimalarial; Antipneumocystic, and has also been used to treat toxoplasmosis. It is an analog of protozoan mitochondrial protein ubiquinone, and acts by inhibiting the cytochrome bc(1) complex via interactions with the Rieske iron-sulfur protein and cytochrome b in the ubiquinol oxidation pocket.

Pneumocystis pneumonia (PCP) is associated with significant morbidity and mortality in renal transplant recipients (RTR). Trimethoprim-sulfamethoxazole (TMP-SMZ) is considered the prophylactic agent-of-choice. Some patients require an alternative owing to TMP-SMZ intolerance. This is the first evaluation of full-dose atovaquone vs.
