Voriconazole is a triazole antifungal medication used to treat serious fungal infections. Voriconazole binds and inhibits ergosterol synthesis by inhibiting CYP450-dependent 14-alpha sterol demethylase. The inhibition of 14-alpha sterol demethylase results in a depletion of ergosterol in fungal cell membrane.
CYP3A4, CYP2C9 and CYP2C19 inhibitors and inducers: Adjust Voriconazole dosage and monitor for adverse reactions or lack of efficacy Voriconazole may increase the concentrations and activity of drugs that are CYP3A4, CYP2C9 and CYP2C19 substrates. Reduce doses of these other drugs and monitor for adverse reactions Increase maintenance oral and intravenous dosage of Voriconazole with co-administration of Phenytoin or Efavirenz
The most common side effects are abdominal pain, anemia, blurred vision, headache, chest pain, nausea and diarrhea.
There is no data found about overdose of Voriconazole.
There are no adequate and well-controlled studies in pregnant woman. It should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Long term exposure (treatment or prophylaxis) greater than 180 days requires careful assessment of the benefit-risk balance. Squamous cell carcinoma of the skin (SCC) has been reported in relation with long-term voriconazole treatment.
The efficacy to the children under 12 years of age is not established.
