Résumé / Abstract
Neuropathic pain is a condition affecting a significant proportion of the world's population. Many therapeutic drugs have been used. They achieve less than satisfactory results and are associated to common side effects that affect the daily life of patients. Pregabalin is a new drug that has been shown to be effective for treating partial epilepsy and peripheral neuropathic pain in clinical trials. It is a structural, but not functional, analogue of GABA. It acts as a ligand of the alpha2-delta subunit, a protein associated to the voltage-dependent calcium channels. Modulation of these channels decreases calcium entry into nerve endings, resulting in a decreased release of several excitatory neurotransmitters. Pregabalin had a linear pharmacokinetics with little variability between the different subjects. It does not bind to plasma proteins, has no liver metabolism, and is excreted trough the kidneys. Few interactions with other drugs may be expected based on these characteristics. In clinical trials, pregabalin has been shown to be effective in postherpetic neuralgia and painful diabetic neuropathy at doses ranging from 150-600 mg/day. The analgesic effects of pregabalin occur in the first few days of treatment and are sustained over time. Side effects are few; most are transient and well-tolerated by patients, and the treatment discontinuation rate is minimal.
