Björn Pasternak

Björn Pasternak is a Research Professor leading the Pharmacoepidemiology group at the Department of Medicine, Solna, Karolinska Institutet. His team specializes in large-scale registry studies focused on adverse drug effects, with research programs in pediatric pharmacoepidemiology, safety of diabetes medications, and rapid assessment of drug safety concerns. The group leverages high-quality epidemiological methods to inform evidence-based clinical decisions.

Pasternak's research interests span pharmacoepidemiology, drug safety, diabetes outcomes, cardiovascular risk, and perinatal health. His work utilizes nationwide registries to evaluate real-world drug effects, socioeconomic disparities in treatment, and long-term outcomes of chronic therapies. Key focuses include GLP-1 receptor agonists, SGLT2 inhibitors, antibiotic use in pregnancy, and opioid safety.

Recent publications demonstrate strong emphasis on Scandinavian cohort studies of diabetes medications (GLP-1 agonists, SGLT2 inhibitors) and their associations with thyroid cancer, liver events, intestinal obstruction, and cardiovascular/renal outcomes. Other trends include perinatal pharmacovigilance (antibiotics, acid-suppressive drugs) and neurodegenerative risks in athletes.
