Long-term prophylaxis (LTP) is essential for decreasing the frequency and severity of attacks. This study aims to compare the safety profiles of two first-line LTP therapies, both of which inhibit kallikrein: berotralstat (oral) and lanadelumab (subcutaneous), using data from the WHO's VigiBase pharmacovigilance database. Materials and Methods: The study employed a retrospective quantitative design, utilizing the World Health Organization's pharmacovigilance database, VigiAccess, which contains individual case safety reports of adverse drug reactions (ADRs) to identify cases of ADRs associated with HAE-C1-INH long-term prophylaxis. Results: A total of 644 reports for berotralstat and 3432 reports for lanadelumab were analyzed. Berotralstat was mainly associated with gastrointestinal adverse events (47.9%), while lanadelumab was linked to injection site reactions (45.9%), infections (23.3%), musculoskeletal and connective tissue disorders (10%), immune system disorders (5.3%), vascular disorders (4.7%), and metabolic issues (3.9%). Female patients were more frequently affected in both groups. Statistically significant differences were observed, reflecting the differences in administration methods and pharmacological profiles between the two drugs. Limitations include the self-reported nature of the data and the absence of detailed clinical information. Conclusions: The results confirmed the literature's data on the gastrointestinal adverse effects of berotralstat, as well as site reactions and infections associated with lanadelumab. Notably, musculoskeletal and connective tissue disorders, immune system disorders, vascular disorders, and metabolic issues occurred more frequently in patients using lanadelumab.PMID:41303734 | PMC:PMC12654361 | DOI:10.3390/medicina61111897
