National impact of a constraining regulatory framework on pregabalin dispensations in France, 2020-2022.

Background: Pregabalin is a drug approved for neuropathic pain, epilepsy and general anxiety disorder. However, pregabalin is also an increasing cause of diversion and misuse, and, for this reason, the French health authorities have decided in 2021 to classify it as a narcotic drug, requiring secured prescription pads. Our study aimed to evaluate the impact of this measure on pregabalin dispensation patterns.
