The potassium binder patiromer (Veltassa) was deemed safe and well-tolerated in patients with hyperkalemia, post-marketing data showed. Since its approval in October 2015, real-world data from the past 4 years found the sodium-free drug had a similar safety profile as it did in the clinical trials, reported Matthew Weir, MD, of the University of Maryland School of Medicine in Baltimore, in a poster at the virtual National Kidney Foundation Spring Clinical meeting. "Real-world clinical experience may differ from clinical trial experience," Weir and colleagues explained. "Therefore, a global pharmacovigilance database has been established to report, document, and evaluate post-marketing experience with patiromer."
