<i>Retracted:</i> The efficacy and safety of diacerein in the treatment of painful osteoarthritis of the knee: A randomized, multicenter, double‐blind, placebo‐controlled study with primary end points at two months after the end of a three‐month treatment period

Abstract

This is the first published study of a symptomatic slow-acting OA drug in which the time of assessment of the primary outcome end points was 2 months after the end of a 3-month treatment period. The results show that diacerein is safe and effective for the treatment of knee OA and has a long carryover effect.
