Polypharmacy Impairs Rheumatoid Arthritis Outcomes
A French early rheumatoid arthritis (RA) study has shown that polypharmacy (PP) was associated with significant lower treatment responses and more serious adverse events (SAEs).
Data was drawn from the French ESPOIR study, a prospective study of early RA. Polypharmacy was defined as concurrent use of 2 or more non-RA medications by the patient. The endpoints were the occurrence of SAEs (severe infections, hospitalizations, deaths) throughout a 10-year follow-up period.
