Observational Study
Topical ambroxol for the treatment of neuropathic pain : An initial clinical observation. English version.
Neuropathic pain is difficult to treat, and the available options are often inadequate. The expectorant ambroxol also acts as a strong local anaesthetic and blocks sodium channels about 40 times more potently than lidocaine. It preferentially inhibits the channel subtype Nav 1.8, which is expressed especially in nociceptive C-fibres. In view of the low toxicity of ambroxol, it seemed reasonable to try using it for the treatment of neuropathic pain that failed to respond to other standard options. ⋯ Ambroxol acts as a strong local anaesthetic and preferentially inhibits the nociceptively relevant sodium channel subtype Nav 1.8. For the first time, we report below on a relevant pain relief following topical ambroxol 20% cream in patients with neuropathic pain. In view of the positive side effect profile, the clinical benefit in patients with pain should be investigated further.

Case Reports Comparative Study
[Topical ambroxol for the treatment of neuropathic pain : A first clinical observation. German version].
Neuropathic pain is difficult to treat and available options are frequently not sufficient. The expectorant ambroxol also works as a strong local anesthetic and blocks sodium channels about 40 times more potently than lidocaine. Ambroxol preferentially inhibits the channel subtype Nav 1.8, which is expressed particularly in nociceptive C fibers. Due to the low toxicity, topical ambroxol seemed to represent a reasonable therapeutic attempt for treatment of neuropathic pain resistant to other standard options. ⋯ Ambroxol acts as a strong local anesthetic and preferentially inhibits the nociceptive-relevant sodium channel subtype Nav 1.8. For the first time, we report relevant pain reduction following topical Ambroxol 20% cream in patients with neuropathic pain. Regarding the advantageous profile with rare side effects, the clinical benefit for pain patients should be further investigated.

Multimodal pain treatment programs are widely accepted as the medical treatment standard in the management of patients with chronic pain syndromes. The concepts and treatment strategies are based on the biopsychosocial model of pain and programs for early restoration of function. ⋯ Despite the assumed similarities, significant differences in, for example the aims of the therapy and relevant structural and process variables have to be kept in mind when allocating patients to a program as provided by a hospital or a rehabilitation clinic. The aim of this article is to present the framework structures of both treatment levels with respect to the implementation of multimodal pain therapy programs and to elucidate the differential diagnostic approach to the indications.
