Tramadol is a centrally acting analgesic for the treatment of moderate to severe pain. Tramadol has a 30-year history of efficacy and safety and is currently marketed in more than 70 countries worldwide, primarily in formulations that require multiple doses per day.

Studies have shown that tramadol provides relief from both acute and chronic pain conditions, including osteoarthritis pain, low back pain, cancer pain, post-operative pain and dental pain. Tramadol avoids the potentially serious side effects such as gastrointestinal bleeding that may be caused by NSAIDs and the potential cardiovascular events recently attributed to COX-2 inhibitors.

Compared to stronger opioids, tramadol has, in clinical studies,
demonstrated a lower incidence of major side effects, such as respiratory
depression.
