Griebeler ML, Morey-Vargas OL, Brito JP, et al. Pharmacologic interventions for painful diabetic neuropathy: An umbrella systematic review and comparative effectiveness network meta-analysis. Ann Intern Med. 2014;161:639-49.
Review question
In adults with painful neuropathy due to diabetes, which drugs best relieve pain?
Background
People with diabetes can get neuropathy. Symptoms of diabetic neuropathy can include pain, most often felt in the legs and feet. Diabetic neuropathy cannot be cured, but oral drugs and topical drugs can reduce the pain. Different drugs have different side effects.
How the review was done
The researchers did a systematic review, searching for studies that were published up to April 2014.
They found 65 randomized controlled trials with 12,632 people (mostly men). The average age was 46 to 65 years.
The key features of the studies were:
- people were at least 18 years of age and had painful diabetic neuropathy;
- most drugs were compared with placebo and given for 12 weeks or less; and
- studies that used combinations of drugs were excluded.
Trials were combined using a type of analysis that lets you compare treatments even if they were not compared directly in the individual trials.
What the researchers found
At 3 months or less:
- anticonvulsants, serotonin–norepinephrine reuptake inhibitors, tricyclic antidepressants, and topical capsaicin reduced pain more than placebo; and
- serotonin–norepinephrine reuptake inhibitors reduced pain more than anticonvulsants, opioids, or mexiletine.
Few trials assessed drugs taken for more than 3 months. Of those that did, anticonvulsants taken for up to 22 weeks reduced pain more than placebo.
Side effects of drugs varied.
Conclusions
In people with painful diabetic neuropathy, anticonvulsants, serotonin–norepinephrine reuptake inhibitors, tricyclic antidepressants, and topical capsaicin reduce pain at up to 3 months. Serotonin–norepinephrine reuptake inhibitors work better than anticonvulsants.

Que dois-je manger? Types de gras
Harvard School of Public HealthIl existe trois principaux types de matières grasses: les gras insaturés, saturés et trans. Les gras insaturés peuvent aider à améliorer le taux de cholestérol et réduire l'inflammation. On les retrouve dans l'huile d'olive, les avocats, les noix, les graines et les poissons. Les gras trans sont fréquents dans la malbouffe et peuvent augmenter votre risque de maladie du coeur, d'accident vasculaire cérébral, de diabète et d'autres maladies chroniques.
