Drug Drug Interaction

The objectives of this manuscript are to describe a case report of a patient whose phenelzine maintenance therapy was discontinued due to concern for a phenelzine-morphine drug interaction, to review the available literature regarding the potential for this drug-drug interaction, and provide recommendations for this clinical scenario. A PubMed/MEDLINE literature search was conducted and all publications determined to be relevant to this case report were included. Literature describing in vitro data, case reports/human studies, and review articles concerning the interaction between morphine and monoamine oxidase inhibitors (MAOIs) were included. A total of 14 publications pertinent to the potential phenelzine-morphine interaction were included in this review including 5 in vitro studies, 4 human studies, and 6 review articles detailing the drug interaction profile between opioids and antidepressants. Of these publications, only a single case report of a potential drug interaction between morphine and phenelzine was identified. The literature suggesting a drug interaction between morphine and phenelzine is limited. The combination of phenelzine and morphine, with close monitoring for signs and symptoms of serotonin syndrome, is reasonable for patients with appropriate indications for both agents.

Sepsis Care

Background: Many antibiotics have a high potential for having an interaction with drugs, as perpetrator and/or victim, in critically ill patients, and particularly in sepsis patients. Methods: The aim of this review is to summarize the pharmacokinetic drug-drug interaction (DDI) of 45 antibiotics commonly used in sepsis care in China. Literature mining was conducted to obtain human pharmacokinetics/dispositions of the antibiotics, their interactions with drug metabolizing enzymes or transporters, and their associated clinical drug interactions. Potential DDI is indicated by a DDI index > 0.1 for inhibition or a treated-cell/untreated-cell ratio of enzyme activity being > 2 for induction. Results: The literature-mined information on human pharmacokinetics of the identified antibiotics and their potential drug interactions is summarized. Conclusion: Antibiotic-perpetrated drug interactions, involving P450 enzyme inhibition, have been reported for four lipophilic antibacterials (ciprofloxacin, erythromycin, trimethoprim, and trimethoprim-sulfamethoxazole) and three lipophilic antifungals (fluconazole, itraconazole, and voriconazole). In addition, seven hydrophilic antibacterials (ceftriaxone, cefamandole, piperacillin, penicillin G, amikacin, metronidazole, and linezolid) inhibit drug transporters in vitro. Despite no reported clinical PK drug interactions with the transporters, caution is advised in the use of these antibacterials. Eight hydrophilic antibacterials (all β-lactams; meropenem, cefotaxime, cefazolin, piperacillin, ticarcillin, penicillin G, ampicillin, and flucloxacillin), are potential victims of drug interactions due to transporter inhibition. Rifampin is reported to perpetrate drug interactions by inducing CYP3A or inhibiting OATP1B; it is also reported to be a victim of drug interactions, due to the dual inhibition of CYP3A4 and OATP1B by indinavir. In addition, three antifungals (caspofungin, itraconazole, and voriconazole) are reported to be victims of drug interactions because of P450 enzyme induction. Reports for other antibiotics acting as victims in drug interactions are scarce.

This review examines three bodies of literature related to herb–drug interactions: case reports, clinical studies, evaluations found in six drug interaction checking resources. The aim of the study is to examine the congruity of resources and to assess the degree to which case reports signal for further study. A qualitative review of case reports seeks to determine needs and perspectives of case report authors. Methods: Systematic search of Medline identified clinical studies and case reports of interacting herb–drug combinations. Interacting herb–drug pairs were searched in six drug interaction resources. Case reports were analyzed qualitatively for completeness and to identify underlying themes. Results: Ninety-nine case-report documents detailed 107 cases. Sixty-five clinical studies evaluated 93 mechanisms of interaction relevant to herbs reported in case studies, involving 30 different herbal products; 52.7% of these investigations offered evidence supporting reported reactions. Cohen’s kappa found no agreement between any interaction checker and case report corpus. Case reports often lacked full information. Need for further information, attitudes about herbs and herb use, and strategies to reduce risk from interaction were three primary themes in the case report corpus. Conclusions: Reliable herb–drug information is needed, including open and respectful discussion with patients.

Abstract Background Cornin is a commonly used herb in cardiology for its cardioprotective effect. The effect of herbs on the activity of cytochrome P450 enzymes (CYP450s) can induce adverse drug-drug interaction even treatment failure. Therefore, it is necessary to investigate the effect of cornin on the activity of CYP450s, which can provide more guidance for the clinical application of cornin. Methods Cornin (100 μM) was incubated with eight isoforms of CYP450s, including CYP1A2, 2A6, 3A4, 2C8, 2C9, 2C19, 2D6, and 2E1, in pooled human liver microsomes. The inhibition model and corresponding parameters were also investigated. Results Cornin exerted significant inhibitory effect on the activity of CYP3A4, 2C9, and 2E1 in a dose-dependent manner with the IC50 values of 9.20, 22.91, and 14.28 μM, respectively (p < 0.05). Cornin inhibited the activity of CYP3A4 non-competitively with the Ki value of 4.69 μM, while the inhibition of CYP2C9 and 2E1 by cornin was competitive with the Ki value of 11.31 and 6.54 μM, respectively. Additionally, the inhibition of CYP3A4 by cornin was found to be time-dependent with the KI/Kinact value of 6.40/0.055 min− 1·μM− 1. Conclusions The inhibitory effect of cornin on the activity of CYP3A4, 2C9, and 2E1 indicated the potential drug-drug interaction between cornin and drugs metabolized by these CYP450s, which needs further investigation and validation.

Abstract Background This case report demonstrates pericardial effusion, acute pericarditis, and cardiac tamponade in an otherwise healthy woman who had a positive test result for coronavirus disease 2019. Few case reports have been documented on patients with this presentation, and it is important to share novel presentations of the disease as they are discovered. Case presentation A Caucasian patient with coronavirus disease 2019 returned to the emergency department of our hospital 2 days after her initial visit with worsening chest pain and shortness of breath. Imaging revealed new pericardial effusion since the previous visit. The patient became hypotensive, was taken for pericardial window for cardiac tamponade with a drain placed, and was treated for acute pericarditis. Conclusion Much is still unknown about the implications of coronavirus disease 2019. With the novel coronavirus disease 2019 pandemic, research is still in process, and we are slowly learning about new signs and symptoms of the disease. This case report documents a lesser-known presentation of a patient with coronavirus disease 2019 and will help to further understanding of a rare presentation.
