Abstract
Although the efficacy of lopinavir/ritonavir has not been proven, it has been proposed as an off-label treatment for COVID-19. Previously, it has been reported that the plasma concentrations of lopinavir significantly increase in inflammatory settings. As COVID-19 may be associated with major inflammation, assessing the plasma concentrations and safety of lopinavir in COVID-19 patients is essential.
Methods:
Real-world COVID-19 data based on a retrospective study.
Results:
Among the 31 COVID-19 patients treated with lopinavir/ritonavir between March 18, 2020 and April 1, 2020, higher lopinavir plasma concentrations were observed, which increased by 4.6-fold (interquartile range: 3.6–6.2), compared with the average plasma concentrations in HIV. Lopinavir concentrations in all except one patient were above the upper limit of the concentration range of HIV treatment. Approximately one to 5 patients prematurely stopped treatment mainly because of an ADR related to hepatic or gastrointestinal disorders.
Conclusions:
Lopinavir plasma concentrations in patients with moderate-to-severe COVID-19 were higher than expected, and they were associated with the occurrence of hepatic or gastrointestinal adverse drug reactions. However, a high plasma concentration may be required for in vivo antiviral activity against SARS-CoV-2, as suggested by previous studies. Therefore, in the absence of adverse drug reaction, lopinavir dosage should not be reduced. Caution is essential because off-label use can be associated with a new drug safety profile.

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Our study has several limitations. First, due to the retrospective design using data from routine care, plasma assays were drawn at different times that prevent from an accurate pharmacokinetic estimation. Second, according to different practices in wards, Covid-19 severity at baseline was heterogeneous between patients. However, most importantly, in all assayed patients, LPV plasma concentrations regardless assays timing were unexpectedly high comparing HIV experience. Finally, unbound concentrations, which are the active ones, were not estimated.
