Incidence of spontaneous notifications of adverse reactions with aceclofenac, meloxicam, and rofecoxib during the first year after marketing in the United Kingdom

Safety and effectiveness of 4-week therapy with aceclofenac controlled release once a day

Aceclofenac controlled-release (CR) is a once-a-day tablet with 200 mg of aceclofenac, and is bioequivalent to conventional aceclofenac. However, its safety in humans has not been well studied in Korea. Therefore, we aimed to evaluate the overall incidence and patterns of adverse events (AEs), the effectiveness of aceclofenac CR, and the differences in incidence rates of the AEs based on each patient’s baseline charateristics. This study was conducted on patients receiving aceclofenac CR in clinical practice at each investigational institution to treat musculoskeletal pain and inflammation. The subjects were administered one tablet of aceclofenac CR (200 mg once-a-day) and were observed for 4 weeks post-administration. Factors affecting the occurrence of AEs were evaluated, and the Visual Analogue Scale (VAS) was used to measure the pain intensity. Among 14,543 subjects, the incidence rate of AEs was 0.86%, and that of adverse drug reactions was 0.74%. No serious AEs and unexpected adverse drug reactions were monitored. The incidence rates of AEs were significantly higher in females, inpatient treatment, individuals with concurrent disorders, and those receiving concomitant medications, respectively (all P < 0.05). Four weeks post-using aceclofenac CR, the mean changes in VAS was significantly decreased compared to prior administration. The overall clinical efficacy rate was 91.63%. This study confirmed that no severe adverse reactions were observed for aceclofenac CR exceeding those previously reported for safety results of conventional formulation of this drug in routine clinical practice settings. The use of aceclofenac CR might not violate the previously reported information on the safety and effectiveness of aceclofenac.

A Review of Aceclofenac: Analgesic and Anti-Inflammatory Effects on Musculoskeletal Disorders

Aceclofenac is an oral non-steroidal anti-inflammatory drug (NSAID) with anti-inflammatory and analgesic properties. Although there are some differences in the authorized indications between countries, aceclofenac is mainly recommended for the treatment of inflammatory and painful processes, such as low back pain (LBP), scapulohumeral periarthritis, extraarticular rheumatism, odontalgia, and osteoarthritis (OA), rheumatoid arthritis (RA), and ankylosing spondylitis (AS). The analgesic properties and tolerability profile of aceclofenac in musculoskeletal disorders are reviewed, focusing on relevant and recent studies. The efficacy and safety comparison of aceclofenac with other analgesics and anti-inflammatory agents in OA, AS, RA, and LBP is described. Relevant studies were identified following a literature search of PubMed using the terms "aceclofenac" and "clinical trials" published from 1 Jan 1992 to 1 Jan 2020. Aceclofenac is at least as effective as other NSAIDs in reducing pain and/or improving functional capacity in chronic pain conditions (OA, AS, RA, and LBP). It is generally well tolerated and appears to have a more favorable GI profile than other NSAIDs. Thus, current evidence indicates that aceclofenac is a useful option for the management of pain and inflammation across a wide range of painful conditions.

Adverse drug reactions associated with the use of NSAIDs: a case/noncase analysis of spontaneous reports from the French pharmacovigilance database 2002-2006

To evaluate the safety profile of eight oral nonsteroidal anti-inflammatory drugs (NSAIDs) available in France, using data reported through the French pharmacovigilance system. Data (from 2002 to 2006) were analysed for aceclofenac, diclofenac, ketoprofen, meloxicam, naproxen, nimesulide, piroxicam and tenoxicam, focusing on the reported rates of serious adverse drug reactions (ADRs) in the following system organ classes: gastrointestinal, hepatic, cutaneous, renal and cardiovascular. A total of 42 389 serious ADR reports were identified, and 38 506 were included in a case/noncase analysis. Ketoprofen was associated with the highest cumulative reported rate of serious ADRs (0.78 cases per million defined daily doses), followed by diclofenac (0.58), nimesulide (0.52), naproxen (0.50), piroxicam (0.47), tenoxicam (0.42), meloxicam (0.41) and aceclofenac (0.30). The most frequently reported serious ADRs were cutaneous, followed by gastrointestinal, hepatic, renal and rarely, cardiovascular events. In the case/noncase analysis, ketoprofen, piroxicam and naproxen were associated with the highest risk of serious gastrointestinal ADRs (odds ratios [ORs] of 6.87, 6.54 and 5.07, respectively). Nimesulide and aceclofenac were associated with the highest risk of liver ADRs (adjusted ORs of 4.53 and 3.67, respectively), as was meloxicam for cutaneous ADRs (adjusted OR of 3.15) and tenoxicam for renal ADRs (adjusted OR of 3.17). The most frequent serious ADRs reported with the selected oral NSAIDs are cutaneous, followed by gastrointestinal, hepatic and renal events. The highest risks for serious gastrointestinal, hepatic, cutaneous and renal adverse events were linked, respectively, with ketoprofen, nimesulide, meloxicam and tenoxicam compared with the other NSAIDs.
