Crisugabalin, a ligand for the α2δ subunit of voltage-gated calcium channels, exhibits no obvious abuse potential in rodents. (PubMed, Pharmacol Biochem Behav) - "Secondly, a rat drug discrimination study was employed to determine the pharmacological similarity between crisugabalin and the training drug midazolam. In the rat spontaneous withdrawal study, crisugabalin demonstrated a very low level of physical dependence. These findings suggest that crisugabalin has minimal to no potential for abuse, thereby establishing itself as a safer option relative to pregabalin and mirogabalin."
