[Local treatment of rheumatic diseases with the 5-HT3 receptor antagonist tropisetron]

Local injection of the 5-HT3 receptor antagonist tropisetron manifests a distinct analgesic effect in various local diseases of the locomotor system such as tendinopathies, peri-arthropathies,myofascial pain syndrome, in trigger points, and in inflammatory joint processes.This effect corresponds to that exerted by local anesthetics in general use such as lidocaine and prilocaine among others, but the effect lasts considerably longer. The reason for this finding is found in a simultaneous antiphlogistic effect of the 5-HT3 receptor antagonist as evidenced by animal experiments and clinical data.
