Efficacy and tolerability of #duloxetine in patients with knee #osteoarthritis: a meta‐analysis of randomised controlled trials

..Duloxetine achieved significant reductions in primary outcomes including Brief Pain Inventory 24‐h average pain score (weighted mean difference (WMD) = −0.74, 95% confidence interval (CI) = −0.92 to −0.57), weekly mean of the 24‐h average pain score (WMD = −0.76, 95% CI = −0.96 to −0.56), WOMAC stiffness score (WMD = −0.47, 95% CI = −0.60 to −0.34) and WOMAC physical function score (WMD = −4.44, 95% CI = −5.24 to −3.64). Furthermore, duloxetine demonstrated a higher number of treatment‐emergent adverse events (risk ratio (RR) = 1.31, 95% CI = 1.20–1.44) and discontinuations (RR = 2.26, 95% CI = 1.63–3.12); however, no difference in serious adverse events (RR = 0.92, 95% CI = 0.40–2.11) was observed.

Conclusion
Duloxetine is effective in the management of chronic pain and loss of physical function in knee OA with acceptable adverse events despite having no advantage in treating joint stiffness. Future trials should focus on determining the optimal treatment regimen
