Non-opioid analgesics are commonly used to treat mild and moderate acute and chronic pain. They can be used as monotherapy; however, they have greater efficacy in combination with weak and strong opioids. Unlike opioids, long-term use of non-steroidal anti-inflammatory drugs does not lead to physical dependence. One of the main disadvantages of the NSA is the risk of gastrointestinal side effects, especially bleeding into the digestive tract. This is increased especially in ulcerative disease and in higher doses, but also in the elderly (over 65 years), also with concomitant administration of corticosteroids, anticoagulants or other NSAIDs.
