The solid material is the sorbent, and the substance in the adsorbed state is called adsorbate.

The development of devices and materials for hemoadsorption started in the 1970s, where activated charcoal coated in a plastic case was used as a sorbent for patients with drug overdose. Further developments of adsorbent materials led to the creation of several cartridges, which are now available for clinical use and are deployed for a myriad of purposes.

However, these devices may unintentionally remove therapeutic medications, potentially compromising efficacy. Understanding these interactions is essential to optimize therapy and ensure patient safety. Methods A systematic search of PubMed, Cochrane, and manufacturer-specific databases was performed to identify literature on drug removal by current adsorptive EBP devices. Studies were screened for evidence of drug clearance, including both preclinical and clinical (in-vivo) data, using specific keywords related to drug removal and therapeutic drug monitoring (TDM). Results Out of 659 identified articles, 61 met the inclusion criteria. CytoSorb was the most extensively studied device, with 25 relevant publications-19 of which included in-vivo data. Data on drug removal were found for 43 substances with CytoSorb, 8 with Jafron, 12 with oXiris, 25 with Seraph, and 13 with PMX-HP. Antibiotics were the most commonly studied drug class, with vancomycin and meropenem being the most frequently investigated agents. While CytoSorb had the most comprehensive data, evidence for other devices was limited, especially regarding clinical studies. Conclusions Adsorptive EBP devices have the potential to unintentionally remove medications, which may compromise therapeutic effectiveness in critically ill patients if not properly accounted for. Among currently available devices, CytoSorb has the most comprehensive evidence base. However, additional clinical studies are required for all devices to confirm findings and establish dosing recommendations.
