Voriconazole 40 mg/mL Oral Suspension is a potent antifungal medication used primarily to treat serious fungal infections such as invasive aspergillosis, candidemia in non-neutropenic patients, esophageal candidiasis, and other serious fungal infections caused by Scedosporium and Fusarium species. This liquid dosage form ensures that the active ingredient is uniformly dispersed throughout the liquid medium, providing a homogeneous mixture for administration, which is particularly beneficial for patients who have difficulty swallowing tablets or require precise dosing adjustments.

When considering the use of Voriconazole 40 mg/mL Oral Suspension, it is crucial to be aware of potential drug interactions, as voriconazole is known to interact with a wide range of medications. Voriconazole is primarily metabolized by the cytochrome P450 enzymes CYP2C19, CYP2C9, and CYP3A4. As a result, it can both inhibit and be affected by other drugs that are substrates, inhibitors, or inducers of these enzymes.

One of the most significant interactions is with drugs that are strong inducers of CYP450 enzymes, such as rifampin, carbamazepine, and phenobarbital. These medications can significantly decrease voriconazole plasma concentrations, potentially leading to therapeutic failure. Conversely, voriconazole can increase the plasma concentrations of drugs metabolized by CYP3A4, such as certain statins, leading to an increased risk of adverse effects like rhabdomyolysis.

Voriconazole can also interact with anticoagulants like warfarin, increasing the risk of bleeding due to elevated INR levels. Close monitoring of INR and dose adjustments of warfarin may be necessary. Additionally, voriconazole can increase the levels of certain benzodiazepines, such as midazolam and triazolam, leading to enhanced sedative effects. Caution is advised when co-administering these medications, and dose adjustments may be required.

Other notable interactions include those with immunosuppressants such as cyclosporine and tacrolimus, where voriconazole can increase their plasma concentrations, necessitating careful monitoring and potential dose reductions to avoid toxicity. Furthermore, co-administration with certain HIV protease inhibitors and non-nucleoside reverse transcriptase inhibitors can lead to altered plasma levels of either voriconazole or the antiretroviral drugs, requiring careful consideration and possible dose adjustments.

Patients and prescribers should also be aware of the potential for QT interval prolongation when voriconazole is used concomitantly with other drugs known to prolong the QT interval, such as certain antiarrhythmics, antipsychotics, and macrolide antibiotics. This can increase the risk of life-threatening arrhythmias, and ECG monitoring may be warranted in such cases.

Given the complexity of voriconazole's drug interaction profile, it is essential for healthcare providers to conduct a thorough medication review and consider potential interactions before initiating therapy. Patients should be advised to inform their healthcare provider of all medications they are currently taking, including over-the-counter drugs and supplements, to ensure safe and effective use of voriconazole.
