Drug Interactions with Darunavir

When considering the use of darunavir, it is crucial to be aware of potential drug interactions to ensure the safe and effective use of this medication.​ Darunavir interacts with 481 medications, including common drugs like amlodipine, atorvastatin, and prednisone.​ It is important to note that darunavir is primarily metabolized by the enzyme cytochrome P450 (CYP) 3A4, and co-administration with inhibitors of CYP3A4 can lead to increased plasma concentrations of darunavir.​ Special caution should be taken when using darunavir in combination with drugs that are highly dependent on CYP3A for metabolism, as this could result in serious or life-threatening events.​

Cautions for Darunavir Use

When using darunavir, it is important to exercise caution, especially in cases where there may be drug interactions or specific contraindications.​ One key caution to be mindful of is the co-administration of darunavir with drugs highly reliant on CYP3A for metabolism. Elevated plasma concentrations of darunavir can occur when it is combined with such medications٫ potentially leading to serious or life-threatening events.​ Therefore٫ healthcare providers should be vigilant when prescribing darunavir alongside CYP3A-dependent drugs to mitigate adverse effects.​

Specific Drug Interactions

It is imperative to note that there are 481 medications that have known interactions with darunavir.​ Among these interactions, there are 108 classified as major, 352 as moderate, and 21 as minor.​ Some of the common drugs that can interact with darunavir include orlistat, certain antiseizure medications, barbiturates, and specific HIV combination drugs.​ Understanding the specific drug interactions of darunavir is crucial to ensure the safe and effective use of this medication in clinical practice;

Interaction Studies and Recommendations

Drug interaction studies involving darunavir have been conducted to assess potential interactions with other medications frequently co-administered.​ These studies aim to understand the impact of concomitant drug use on the pharmacokinetics of darunavir.​ Recommendations based on these studies suggest caution and monitoring when darunavir is used in combination with certain drugs to optimize therapeutic outcomes and minimize the risk of adverse events.​ Healthcare providers should refer to guidelines and resources that provide detailed drug interaction information to make informed decisions when prescribing darunavir.​
