Intravenous Lidocaine for Fibromyalgia
The effect of intravenous lidocaine infusion on manifestations of fibromyalgia manifestations were recorded before and 4 weeks after treatment. Pain intensity was rated on a numerical scale.The combination of 240 mg intravenous lidocaine (once a week) and 25 mg amitriptyline for 4 weeks did not modify pain intensity or manifestations in patients with fibromyalgia.
Thirty patients ranging in age from 18 to 60 years, with fibromyalgia (American College of Rheumatology criteria: pain in the four quadrants of the body for at least 3 months and a minimum of 11 out of 18 tender points) were studied. Other manifestations were also recorded: sleep disorders, fatigue, subjective edema, depression, and paresthesia.
Criteria for exclusion were alterations in thyroid, rheumatological, renal and hepatic function; trauma; rheumatic, neuromuscular or psychiatric disease; infectious arthropathy; other pain syndromes; drug hypersensitivity, and pregnancy.
All patients received amitriptyline at a dose of 12.5 mg in the first week and 25 mg over the subsequent 4 weeks. Patients of group 1 (n = 15) received 125 mL 0.9% saline and patients of group 2 (n = 15) received 240 mg lidocaine diluted in 125 mL 0.9% saline. The solutions were infused over a period of 1 h, once a week, for 4 weeks (T1, T2, T3 and T4).

Medical and Biotech [MESH] Definitions
A common nonarticular rheumatic syndrome characterized by myalgia and multiple points of focal muscle tenderness to palpation (trigger points). Muscle pain is typically aggravated by inactivity or exposure to cold. This condition is often associated with general symptoms, such as sleep disturbances, fatigue, stiffness, HEADACHES, and occasionally DEPRESSION. There is significant overlap between fibromyalgia and the chronic fatigue syndrome (FATIGUE SYNDROME, CHRONIC). Fibromyalgia may arise as a primary or secondary disease process. It is most frequent in females aged 20 to 50 years. (From Adams et al., Principles of Neurology, 6th ed, p1494-95)
Antiarrhythmic agent pharmacologically similar to LIDOCAINE. It may have some anticonvulsant properties.
A local anesthetic that is similar pharmacologically to LIDOCAINE. Currently, it is used most often for infiltration anesthesia in dentistry. (From AMA Drug Evaluations Annual, 1992, p165)
A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of procaine but its duration of action is shorter than that of bupivacaine or prilocaine.
A colorless liquid with a sharp burning taste and slight odor. It is used as a local anesthetic and to reduce pain associated with LIDOCAINE injection. Also, it is used in the manufacture of other benzyl compounds, as a pharmaceutic aid, and in perfumery and flavoring.
