Introduction:
Nirmatrelvir/ritonavir (Paxlovid®) is the only oral treatment authorized in Europe to treat COVID-19 disease in adults who do not require supplemental oxygen and who are at high risk for progression to severe COVID-19.
It is available in Spain after validation due to the profile of interactions and warnings for use.
The objective is to determine effectiveness, safety and management of interactions.
Method:
Retrospective study of all patients on validated nirmatrelvir/ritonavir treatment at three urban health centres during 2022. Effectiveness was the proportion of participants without COVID-19-related hospitalization or death from any cause through day 28.
Results:
24 patients were analyzed. It was considered effective in 23 (95.8 %). More than 80 % of patients presented potential interaction with the concomitant medication, recommending the temporary suspension of medications, highlighting simvastatin and metamizole.
Conclusions:
Nirmatrelvir/ritonavir has been considered effective but difficult to manage in polymedicated polypathological patients.
