Azole antimycotics and drug interactions in the perioperative period
Purpose Of Review:
A beneficial effect of antifungal prophylaxis on the prevention of invasive fungal infections has increased the use of azole antimycotics in intensive care and during the perioperative period. At the same time more severe illnesses are treated and multiple drug therapies are employed. Thus, the potential for severe drug-drug interactions has increased. Previous studies have shown that azole antimycotics increase the risk of many clinically significant drug interactions with potentially hazardous consequences.
Recent Findings:
A recent pharmacoepidemiological study has found a more than five-fold incidence ratio in the adjusted rate of sudden death from cardiac diseases among those patients who were given simultaneously inhibitors of cytochrome P450 (CYP) enzymes and their substrates. Although new triazole antifungals are well tolerated, they still cause significant inhibition of CYP enzymes.
Summary:
This review focuses on azole antimycotics and anesthetic drugs being used during the perioperative period and discusses the possible clinically significant drug-drug interactions. Azole antimycotics are amongst the strongest inhibitors of CYP-mediated drug metabolism. Anesthesiologists must be aware of the interaction potential of azole antimycotics to be able to adjust their perioperative strategies according to the patient's condition and concomitant medication.
Insights
Azole antifungals, used to prevent fungal infections, can cause dangerous drug interactions with anesthetic drugs. Anesthesiologists must carefully manage these interactions to ensure patient safety during surgery.
Area of Science:
- Pharmacology
- Anesthesiology
- Infectious Diseases
Background:
- Azole antifungals are increasingly used for prophylaxis in intensive care and perioperative settings.
- Concurrent use of multiple medications for severe illnesses elevates the risk of drug-drug interactions.
- Previous research indicates azole antifungals pose a significant risk for clinically relevant drug interactions.
Discussion:
- This review examines drug-drug interactions between azole antifungals and anesthetic agents during the perioperative period.
- Azole antifungals are potent inhibitors of cytochrome P450 (CYP) enzymes, affecting drug metabolism.
- A recent study highlighted a five-fold increased risk of sudden cardiac death with simultaneous use of CYP inhibitors and substrates.
Key Insights:
- Azole antifungals significantly inhibit CYP-mediated drug metabolism.
- Anesthesiologists must be aware of the interaction potential of azole antifungals.
- Perioperative strategies require adjustment based on patient condition and concomitant medications.
Outlook:
- Further research is needed to fully elucidate the mechanisms and clinical impact of these interactions.
- Development of safer antifungal agents or alternative perioperative management strategies may be warranted.
- Enhanced vigilance and communication between healthcare providers are crucial for mitigating risks.
