Abstract
▴ Pregabalin, the pharmacologically active S-enantiomer of 3-aminomethyl-5-methyl-hexanoic acid, has a similar pharmacological profile to that of its developmental predecessor gabapentin, but showed greater analgesic activity in rodent models of neuropathic pain.
▴ The exact mechanism of action of pregabalin is unclear, although it may reduce excitatory neurotransmitter release by binding to the α2-gd protein subunit of voltage-gated calcium channels.
▴ Oral pregabalin 150–600 mg/day, administered twice or three times daily, was superior to placebo in relieving pain and improving pain-related sleep interference in three randomised, double-blind, placebo-controlled, multicentre studies of 8–13 weeks’ duration in a total of 776 evaluable patients with postherpetic neuralgia (PHN).
▴ Weekly mean pain scores (primary endpoint; assessed in all three studies) and weekly mean sleep interference scores (assessed in two studies) were significantly improved at 1 week. In two studies, significant improvements in daily mean pain scores were apparent on the first or second day of treatment with pregabalin administered three times daily.
▴ Pregabalin was generally well tolerated when force-titrated over 1 week to fixed dosages (maximum 600 mg/day) in clinical trials that enrolled mostly elderly PHN patients. Dizziness, somnolence and peripheral oedema of mild-to-moderate intensity were the most common adverse events.
