Treatment of acute intense pain requires the use of strong fast-acting analgesics, such as parenteral forms of non-steroidal anti-inflammatory drugs (NSAIDs). Intravenous and intramuscular (i.m.) NSAIDs administration increases the bioavailability of active substances, allows for analgesic therapy in the presence of restrictions for oral administration, and is predominant in the rate of analgesic action onset versus the latter. When choosing NSAIDs for i.m. administration, the risk of topical post-injection and systemic adverse reactions should be considered. Original meloxicam for i.m. injection is characterized by a favorable risk-benefit ratio and ease of use. In clinical studies, there was no significant increase in creatinine phosphokinase levels, reflecting damage to muscle fibers, after a series of injections of meloxicam i.m. versus other NSAIDs, such as diclofenac and piroxicam. During the search in PubMed, Medline, Google, there was no description of serious topical complications after i.m. administration of meloxicam. In recent years, several large open-label studies have been conducted in Russia demonstrating the efficacy and safety of meloxicam injectable form in acute/subacute non-specific back pain and injuries. The review provides a brief description of the main clinical studies concerning the original meloxicam for i.m. injection.KEYWORDS: NSAIDs, meloxicam, intramuscularly, efficacy, safety.FOR CITATION: Karateev A.E.
