[Treatment options in painful diabetic polyneuropathy].

Distal symmetrical polyneuropathy is the most frequent manifestation of diabetic neuropathy and crucially contributes to the development of diabetic foot and subsequent amputation in 70 to 80% of all cases. In 10 to 15% of affected patients considerable pain is present, in particular in early diabetic polyneuropathy. This review summarizes evidence based data on prevention, neuroregenerative, and symptomatic treatment of painful diabetic polyneuropathy. The most important clinical trials on treatment and prevention are presented. Conclusions from these clinical studies in particular detailed treatment recommendations including dosage and side effects are given. Combined treatments and escalating therapies for severe pain syndromes are discussed.
