Autoimmune idiopathic inflammatory myopathies (IIMs) are a group of pathologies that are generally characterized by muscle weakness. Their treatment involves glucocorticoids and immunosuppressants. The aim was to identify differences and similarities in the pharmacological management of a group of patients with autoimmune IIMs according to the type of disease, sex, age group, and city of residence in Colombia from 2020 to 2021. Methods. This cross-sectional study identified medication prescription patterns for outpatient use in patients with autoimmune IIMs between 2020 and 2021 based on a population database of 8.5 million Colombians affiliated with the Colombian health system. Sociodemographic and pharmacological variables were considered. Results. A total of 671 patients with autoimmune IIMs were identified, with a median age of 57 years, and 70.9% were women. Overlap myositis was the most frequent disease (31.4%). A total of 91.5% of the patients received pharmacological treatment, mainly systemic glucocorticoids (78.5%), conventional disease-modifying antirheumatic drugs (DMARDs) (74.1%), immunosuppressants (9.1%), and biological DMARDs (3.7%). Pharmacological management predominated among patients with overlap myositis, those who lived in cities, and those affiliated with the contributory regime of the Colombian health system. Conventional DMARDs were prescribed mainly to women and to those older than 65 years. Conclusions. Patients with autoimmune IIMs are not treated homogeneously. The pattern of drug use varies according to the type of IIM, sex, age group, city, and health system regime affiliation.<\/jats:p>","DOI":"10.1155\/2022\/1807571","type":"journal-article","created":{"date-parts":[[2022,7,5]],"date-time":"2022-07-05T16:22:46Z","timestamp":1657038166000},"page":"1-11","source":"Crossref","is-referenced-by-count":1,"title":["Autoimmune Idiopathic Inflammatory Myopathies: Pharmacological Differences and Similarities by Type of Myositis and by Sociodemographic Variables"],"prefix":"10.1155","volume":"2022","author":[{"given":"Luis Fernando","family":"Valladales-Restrepo","sequence":"first","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Farmacoepidemiolog\u00eda y Farmacovigilancia, Universidad Tecnol\u00f3gica de Pereira-Audifarma S.
