Chemistry: The formerly stated precision of "equal to 90%" is unlikely, "about 90%" is more likely the case.

Pregabalin is rapidly absorbed when administered on an empty stomach, with peak plasma concentrations occurring within 1 to 1.5 hours. Pregabalin oral bioavailability is estimated to be greater than or equal to 90%. The rate of pregabalin absorption is decreased when given with food, resulting in delay of approximately 3 hours to reach peak plasma concentrations, with peak levels themselves, decreased by about 25 to 30%.<ref>https://www.drugs.com/ppa/pregabalin.html</ref> Administration with food, however, has no clinically significant effect on the extent of absorption.<ref>http://web.archive.org/web/20160305012454/http://www.ema.europa.eu/docs/en_GB/document_library/EPAR_-_Product_Information/human/000546/WC500046602.pdf</ref>

Pregabalin undergoes negligible metabolism in humans. In experiments using nuclear medicine techniques, it was revealed that approximately 98% of the radioactivity recovered in the urine was unchanged pregabalin. The primary metabolite is N-methyl pregabalin.
