In response to the COVID-19 pandemic, nirmatrelvir/ritonavir was approved as the first per os treatment to prevent severe disease progression. This study explores patients' self-management of nirmatrelvir/r and its impact on their long-term medications, and their experience of the information provided by pharmacists and physicians. Adults receiving nirmatrelvir/r from September 2022 to March 2023 were interviewed via a semistructured telephone survey. Sociodemographic, clinical data, and experience with nirmatrelvir/r and cotreatments were collected and analyzed descriptively. Of the 281 patients receiving nirmatrelvir/r, 100 (36%) participated in this study. Ninety (90%) adhered to nirmatrelvir/r, while 5 (5%) reported early discontinuation and 5 (5%) increased time between dosages. Information gaps regarding side effects, risks, benefits, and mechanisms of action were identified. Due to interactions with nirmatrelvir/r, 43% (n = 43/85) of cotreatments were temporarily interrupted, and 13% (n = 11/85) of doses were adjusted. Patient management of nirmatrelvir/r and cotreatments was successful, but satisfaction toward nirmatrelvir/r information could be improved. This study highlights the importance of ongoing efforts to ensure communication strategies, patient education, and interprofessional collaboration in providing treatments with drug-drug interactions.

Background: Immunocompromised patients remain at risk for protracted SARS-CoV-2 infections with persistent viral shedding that could pose a wider public health risk. The optimal therapeutic strategy remains unknown.
Methods: We describe a sequential case series of immunocompromised adults with protracted SARS-CoV-2 infection who received dual/extended antiviral therapy (median 23d nirmatrelvir/r; 8d remdesivir).

Background: To prevent severe disease, nirmatrelvir/ritonavir (nirmatrelvir/r) is administered to individuals infected with SARS-CoV-2 who are at high risk, and it is currently priced at approximately $1375 in the Netherlands. We aim to evaluate the health outcomes and cost-effectiveness of nirmatrelvir/r among patients with high risk of severe disease.
Methods: We used a decision-analytic model parameterized with clinical and health care utilization data from individuals at high risk who were infected with SARS-CoV-2 between September 2021 and November 2023.

Introduction: High-risk patients with COVID-19 benefit from early treatment to prevent severe outcomes. Sotrovimab, a monoclonal antibody, and oral antivirals such as nirmatrelvir/ritonavir and molnupiravir have been used for early intervention, but their comparative efficacy and safety, particularly during the Omicron-dominant phase, require further evaluation.
Methods: A multicenter, retrospective study performed in southern Italy including all adult patients who received early antiviral treatment (sotrovimab or nirmatrelvir/r or molnupiravir) between January 2022 and February 2024 (omicron phase).

(1) Background: Geriatric patients are at high risk of complications of Coronavirus disease-2019 (COVID-19) and are good candidates for antiviral drugs. (2) Methods: A retrospective study of electronic health records (EHRs) aiming to describe antiviral (nirmatrelvir and ritonavir (nirmatrelvir/r) or remdesivir) use, drug-drug interactions (DDIs) and adverse drug reactions (ADRs) in elderly patients (75 and over), hospitalized with mild-to-moderate COVID-19 between July 2022 and June 2023. (3) Results: Out of 491 patients (mean age: 86.
