Chemotherapy-induced peripheral neuropathy
Brief summary
The aim of this study is to assess if dextromethorphan administered during 4 weeks induces a decrease of pain intensity in breast cancer patients suffering from chemotherapy-induced peripheral neuropathy compared to placebo group.
Detailed description
This is a randomized, placebo-controlled, double-blind, parallel-group clinical trial comparing dextromethorphan and placebo for the treatment of chemotherapy-induced peripheral neuropathy, assessed with a (0-10) numerical scale. Cognition, anxiety, depression, sleep and quality of life are also assessed. The influence of CYP2D6, CYP3A4 and MDR1 polymorphism on the dextromethorphan analgesic efficacy will be measured.
