 Action Inhibits mitochondrial electron transport in metabolic enzymes of microorganisms. This may cause inhibition of nucleic acid and adenosine triphosphate synthesis.

Drug Interactions ::

 Interactions

Food: Food, particularly fats, increases absorption 3-fold. Highly protein-bound drugs: Atovaquone is highly protein bound; interactions may occur because of competition for binding sites. Rifamycins: Decreases steady-state plasma concentrations of atovaquone and increases steady-state plasma concentrations of rifampin.

Drug Assesment ::

 Assessment/Interventions

  • Obtain patient history, including drug history and any known allergies, particularly to antifungal medications. Note existing GI disorders, because these may limit absorption of orally-administered drug.
  • Monitor patient closely for several hours after administering the first dose, even if there is no history of allergy.
  • Monitor renal and GI function during therapy.
  • Observe for signs of superinfection during therapy (eg, yeast infections, black “hairy” tongue, itching in groin area).
  • Monitor for effectiveness during therapy (eg, decreased temperature, decreased lung congestion).
  • If signs and symptoms of hypersensitivity occur (eg, rash, shortness of breath), withhold medication and notify physician.
  • If no improvement in infection occurs within 5 days, notify physician.
  • If severe GI side effects occur, notify physician.

Drug Storage/Management ::

 Administration/Storage

  • Most effective if administered with food, particularly proteins and fats.
  • Do not freeze.

Drug Notes ::

 Patient/Family Education

  • Inform patient that medication is most effective when taken with food (particularly fatty foods), and to notify physician if unable to eat.
