Pacira Pharmaceuticals filed a lawsuit against the FDA over limitations that prohibit the company from more widely marketing Exparel, a post-surgery pain medication. The FDA had warned the drugmaker in 2014 not to promote the use of Exparel in surgeries other than the procedures for which it had been approved, Reuters reported. The lawsuit cites the recent Amarin decision, which allows that drugmaker to promote some off-label uses of its prescription fish-oil pill, Vascepa.

Sanofi’s and Regeneron’s Praluent runs $14,600 per year and Amgen’s Repatha costs $14,100.
