§ 04 — SCIENCE

Gabapentin is a first-line agent for neuropathic pain with FDA approval for postherpetic neuralgia and partial seizures. Clinical efficacy rates are modest, and some reviews question whether net benefits outweigh harms in certain populations. Evidence supports use for menopausal vasomotor symptoms and perioperative opioid sparing, though pediatric perioperative data are insufficient for routine use. Atypical side effects including myoclonus, encephalopathy, and respiratory depression are increasingly recognized. Pharmacokinetics are nonlinear due to saturable oral absorption, making dose-response less predictable than pregabalin.
