Data collected were demographic, the drug class involved (anatomical chemical therapeutic (ATC)), DRP detected and degree of recommendation acceptance. Results Total patients with DRP: 291 (23.3%). Identified DRP: 393 (1.4 DRP/patient). 58.3% were men and median age was 63 (15.7) years. Conclusion and relevance Almost 25% of all patients had a DRP, presenting an incidence of 1.4 DRP/patient, higher than reported in previous series. 83% of evaluable recommendations were accepted. One-third of the recommendations were derived from a wrong dosage, and 15% from drug interactions. Hydroxychloroquine was the most frequently involved drug, probably because of the limited experience and wide spectrum of interactions, followed by antimicrobials such as ceftriaxone and azithromycin, used widely in respiratory tract infections.
