Background: Analgesics are widely used in competitive sports, but their patterns of use and detection in anti-doping controls vary significantly across drug classes. This study examined a decade of Italian anti-doping reports with three aims: to describe trends involving non-steroidal anti-inflammatory drugs (NSAIDs), glucocorticoids, and narcotics; to characterize the distribution of specific active ingredients; and to analyze the relative contribution of these classes to anti-doping violations, placing the findings within the regulatory framework. Methods: Data from national anti-doping reporting systems were analyzed from 2013 to the first half of 2023. Yearly data included tested athletes, athlete declarations of NSAID use, and laboratory analytical findings for prohibited substances (glucocorticoids and narcotics). NSAID prevalence was calculated relative to tested athletes, while glucocorticoid and narcotic findings were assessed as absolute counts and proportions of total violations. Temporal trends were assessed using the Cochran–Armitage test. Results: NSAIDs consistently ranked as the most frequently reported medication, with nearly half of the tested athletes reporting their use and no significant linear trend in overall prevalence. However, a significant shift was observed within the NSAID class, with a marked decrease in declarations of COX-2 selective agents over time. Glucocorticoids accounted for a significant portion of prohibited substances, with fluctuating proportions (showing no significant linear trend), betamethasone being the most common active ingredient. Narcotics appeared only sporadically, although the use of non-prohibited opioids such as tramadol and codeine—absent from official reports—remains relevant for understanding analgesic practices. Conclusions: Analgesic use in Italian elite sports shows distinct patterns driven by therapeutic needs and anti-doping regulations. NSAIDs remain the primary choice for routine pain management, though the type of NSAID reported has shifted significantly. Glucocorticoids represent a notable share of prohibited findings with a fluctuating, rather than steadily increasing, pattern. Narcotics appear only sporadically in violation data. Ongoing monitoring will be crucial to understanding how evolving clinical practices and recent regulatory changes influence future detection trends and athlete health.
