Original Abstract of the Article

Major Findings

Several studies have shown that triazole antifungal drugs, such as itraconazole, ketoconazole, and posaconazole, inhibit the activity of the cytochrome P450 (CYP) isozyme 3A4. This enzyme is responsible for breaking down many medications, including midazolam, a short-acting benzodiazepine. 5 Therefore, these antifungal drugs can potentially increase the levels of midazolam in the body, leading to stronger and longer-lasting effects. 5 Itraconazole has been shown to significantly increase the levels and effects of triazolam, another benzodiazepine, regardless of the time interval between ingestion. 4 This interaction can occur even when triazolam is taken within 24 hours of itraconazole and can last for several days after stopping itraconazole treatment. 4 In severely ill patients, itraconazole absorption can be unreliable and its effectiveness needs to be monitored closely. 1 Additionally, combining terbinafine with itraconazole has shown promising results in treating fungal skin diseases. 6 This combination therapy appears to be more effective than either drug alone, leading to faster symptom improvement, higher cure rates, and shorter treatment durations. 6 Furthermore, itraconazole has shown potential in treating Candida and Aspergillus infections in neutropenic patients, demonstrating effectiveness comparable to amphotericin B, which is a commonly used antifungal agent. 1 , 2 Itraconazole appears to have fewer side effects than amphotericin B and has shown particular promise in treating Aspergillus infections. 1 , 2 On the other hand, azole antifungal drugs like fluconazole and itraconazole can also increase the levels and effects of midazolam. 3 This interaction is more pronounced with oral midazolam compared to intravenous administration. 3 Therefore, it is crucial to be aware of the potential for drug interactions when combining azole antifungals with midazolam and adjust dosages accordingly.

Benefits and Risks

Benefits Summary

Antifungal drugs like itraconazole and terbinafine are effective in treating fungal infections. Azole antifungal drugs have demonstrated effectiveness in treating Candida and Aspergillus infections. Notably, itraconazole has shown fewer side effects compared to amphotericin B and has exhibited superior efficacy in treating Aspergillus infections. Combining terbinafine with itraconazole has shown promising results in treating fungal skin diseases.

Risks Summary

Triazole antifungal drugs, such as itraconazole, ketoconazole, and posaconazole, can inhibit the metabolism of benzodiazepines like midazolam, leading to increased levels and stronger effects. Combining itraconazole with triazolam significantly increases triazolam levels and its effects. When combining these drugs, it's essential to consider the potential for interactions and adjust dosages accordingly.

Comparison of Studies

Commonalities of Studies

These studies consistently demonstrate the potential for triazole antifungal drugs to inhibit the metabolism of benzodiazepines like midazolam, leading to increased levels and effects. They also suggest that combination therapy may be more effective than monotherapy.

Differences of Studies

The studies vary in the specific medications used, dosages, administration methods, and participant characteristics. Therefore, direct comparison of the results is not straightforward. Additionally, sample sizes across the studies differ, which could affect the reliability of the findings.

Consistency and Contradictions of Results

The findings from these studies generally align, suggesting that triazole antifungals can inhibit the metabolism of benzodiazepines like midazolam, potentially leading to increased levels and effects. However, the relatively small sample sizes in some studies could limit the generalizability of the results and warrant further investigation.

Implications for Real-Life Applications

Based on these findings, it is essential to consider the potential for drug interactions when combining triazole antifungals with benzodiazepines and adjust dosages as necessary. While combination therapy may be effective, further research is needed to confirm its safety and efficacy.

Limitations of Current Research

These studies were conducted with relatively small sample sizes, limiting the generalizability of the results. Further investigation is required to assess the long-term effects of these drug interactions.

Directions for Future Research

Future research should focus on larger sample sizes and investigate long-term effects. Additionally, further research is needed to thoroughly evaluate the safety and efficacy of combination therapy.

Conclusion

Triazole antifungal drugs can inhibit the metabolism of benzodiazepines like midazolam, potentially leading to increased levels and effects. Therefore, caution is advised when using these drugs together. Combination therapy may be an effective treatment option for fungal infections, but further research is necessary. If you are taking these medications, it is crucial to consult with your doctor.

Itraconazole in neutropenic patients.

Author: van't WoutJ W

Fungal infection treatment
Itraconazole absorption

A study of 32 neutropenic patients with fungal infections compared the effectiveness of itraconazole and amphotericin B. Both treatments were effective against Candida infections, with 9 out of 16 patients responding to amphotericin B and 10 out of 16 responding to itraconazole. Itraconazole was more effective against Aspergillus infections, with 6 out of 8 patients responding compared to 2 out of 5 on amphotericin B. While amphotericin B treatment was associated with three deaths from Aspergillus infections, no deaths occurred in the itraconazole group. The study suggests that itraconazole may be a promising treatment for systemic fungal infections in neutropenic patients, although further research is needed.

The effects of the systemic antimycotics, itraconazole and fluconazole, on the pharmacokinetics and pharmacodynamics of intravenous and oral midazolam.

Author: OlkkolaK T, AhonenJ, NeuvonenP J

Sedation
Increased midazolam effects

Itraconazole and fluconazole, azole antimycotics, significantly increased the effects of oral midazolam, raising its AUC and peak concentration by 3.5-fold and two-fold, respectively. This interaction also led to a profound increase in psychomotor effects. While the interaction with IV midazolam was weak, large doses of IV midazolam could still lead to clinically significant interactions. Using oral midazolam with itraconazole and fluconazole should be avoided.
