Polypharmacy Increased in Psoriatic Arthritis Save
Psoriatic arthritis (PsA) is plagued by obesity, depression and increased comorbidities; now it appears that polypharmacy adds to the burden of managing PsA.
A study of 11,984 PsA patients in the German BARMER health insurance database from 2021 compared medicines and comorbidities with sex-matched and age-matched controls without inflammatory arthritis. Polypharmacy was defined as ≥5 concomitant drugs.
Compared to controls, PsA patients were prescribed significantly more medications compared to controls; especially for these drug classes:
- Musculoskeletal (81% vs 30%)
- Immunomodulatory (56% vs 2.6%)
- Cardiovascular (62% vs 48%)
- Alimentary tract/metabolic (57% vs 31%)
- Nervous system (50% vs 31%)
Polypharmacy was significantly higher in PsA (49%) compared with controls (17%), more so in women (52%) than men (45%) and increased with age and comorbidities.
Polypharmacy equally affects women and men with PsA. This study did not examine the Adverse drug reaction risk or cost of therapy.
