Study of Analgesic Action of Pregabalin, Duloxetine and Tramadol in Patients With Different Neuropathic Pain Phenotypes. Clinical Study

3/28

Chronic pain is the most frequent cause from which millions of patients suffer worldwide, which makes them unable to work but also greatly affects their quality of life. Chronic pain is a condition in itself. Neuropathic pain is a consequence of damage or disease of the peripheral or central nervous system and presents a heterogeneous clinical profile. A large number of pharmaceutical and non-pharmacological agents, as well as various complementary therapies, have been used in the treatment of neuropathic pain. However, their effectiveness is considered moderate and limited and is under investigation because a significant proportion of patients do not respond satisfactorily to treatment. Purpose: The purpose of the study is to investigate the effectiveness of analgesics in the different phenotypes of neuropathic pain.
