The bioequivalence of two oral formulations containing aceclofenac 100 mg was determined in 24 healthy Indian male volunteers. The study was designed as a single dose, fasting, two-period two-sequence crossover study with a washout period of 1 week. The content of aceclofenac in plasma was determined by a validated HPLC method with UV detection. The preparations were compared using the parameters area under the plasma concentration-time curve (AUC0-t), area under the plasma concentration-time curve from zero to infinity (AUC0-infinity), peak plasma concentration (Cmax), and time to reach peak plasma concentration (tmax). No statistically significant difference was observed between the logarithmic transformed AUC0-infinity and Cmax values of the two preparations. The 90% confidence interval for the ratio of the logarithmic transformed AUC0-t, AUC0-infinity, and Cmax were within the bioequivalence limit of 0.80-1.25.

    • "The relationship between the concentration and peak area was found within the range 0.1–5 µg/ml during linearity studies. Quality control points at low, medium, and high levels were used to determine absolute recovery and within-day (intraday) and between-day (interday) precision and accuracy [7]. "

    • "It has superior selectivity for COX-2 inhibition and thus does not disrupt generation of normal prostaglandin in the stomach mucosa, resulting in reduced gastrointestinal problems and adverse reactions and a high tolerance. Therefore, aceclofenac has been considered suitable for long-term use8,9). In addition, it inhibits generation of interleukin-1 that destroys cartilage in a joint and promotes generation of glycosaminoglycan, a articular cartilage component, contributing to prevention of deterioration of rheumatoid arthritis or OA.

    ABSTRACT: To evaluate the analgesic effect, efficacy and safety of aceclofenac controlled release (CR) in patients with chronic knee osteoarthritis (OA). A total of 125 subjects with chronic knee OA were randomly divided into two groups: one group (n=62) was administered aceclofenac CR once daily and the other (n=63), aceclofenac immediate release (IR) twice a day for 4 weeks. A 100-mm visual analogue scale (VAS), Knee injury and Osteoarthritis Outcome Score (KOOS) and range of motoin (ROM) were evaluated as the outcome measures. To evaluate the safety of the drug, adverse events, vital signs, physical examination findings, clinical laboratory values and electrocardiographic findings were evaluated. The VAS, KOOS and ROM were improved after 4 weeks of administration in both groups, but the differences between the two groups were not statistically significant. Significant differences between the two groups were not shown in the evaluation of the adverse events, vital sign, physical examination results, clinical laboratory values, and electrocardiography. The aceclofenac CR and aceclofenac IR were equally effective in patients with chronic knee OA and the clinical trial results didn't show any significant difference in safety. The new aceclofenac CR formulation was found to be effective and safe with the practical advantage of once daily administration.

    ABSTRACT: In this study the significant effect of chitosan on improving the dissolution rate and bioavailability of aceclofenac has been demonstrated by simple solvent change method. Chitosan was precipitated on aceclofenac crystals using sodium citrate as the salting out agent. The pure drug and the prepared co-crystals with different concentrations of chitosan (0.05-0.6%) were characterized in terms of solubility, drug content, particle size, thermal behaviour (differential scanning calorimetry, DSC), X-ray diffraction (XRD), morphology (scanning electron microscopy, SEM), in vitro drug release and stability studies. The in vivo performance was assessed by preclinical pharmacodynamic (analgesic and anti-inflammatory activity) and pharmacokinetic studies. The particle size of the prepared co-crystals was drastically reduced during the formulation process. The DSC showed a decrease in the melting enthalpy indicating disorder in the crystalline content. The XRD also revealed a characteristic decrease in crystallinity. The dissolution studies demonstrated a marked increase in the dissolution rate in comparison with pure drug. The considerable improvement in the dissolution rate of aceclofenac from optimized crystal formulation was attributed to the wetting effect of chitosan, decreased drug crystallinity, altered surface morphology and micronization. The optimized co-crystals exhibited excellent stability on storage at accelerated conditions. The in vivo studies revealed that the optimized crystal formulation provided a rapid pharmacological response in mice and rats besides exhibiting improved pharmacokinetic parameters in rats.
