Gabapentin is eliminated from the body unchanged through urine, with specific transporters (OCT2 and OCTN1) influencing its excretion.
This study examined how genetic variations (polymorphisms) affect gabapentin's pharmacokinetics in 53 patients with chronic pain, identifying two specific genetic markers but finding only limited impact on drug metabolism.
While renal function and absorption play a major role in gabapentin's clinical pharmacokinetics, the genetic variant SLC22A4 c.1507C>T does not significantly influence its absorption or elimination.
