19 August 2008 – Duloxetine hydrochloride maintained pain reduction in the treatment of diabetic peripheral neuropathic pain (DPNP) for more than six months, according to new data presented at the 12th World Congress on Pain in Glasgow, Scotland.The open-label study, which aimed to evaluate long-term maintenance of effect of duloxetine 60 mg once daily, is the first to assess the efficacy of duloxetine in DPNP beyond three months. The study enrolled 216 patients with DPNP who began eight weeks of treatment with 60 mg of duloxetine once daily. Over this initial eight-week period, 53 percent (N=115) of enrolled patients experienced clinically significant improvement in pain reduction (defined as at least 30 percent pain reduction) as measured by the Brief Pain Inventory (BPI) 24-hour average pain rating. This group of responders was maintained on duloxetine 60 mg (N=103) once daily for up to 26 weeks to evaluate sustained pain reduction. Results at study end showed that the reduction in pain was maintained in 74.8 percent (N=77) of the sustained responders with 60 mg duloxetine over the full study period.
“DPNP is a chronic, potentially disabling, condition requiring treatment over a long period of time,” said Vladimir Skljarevski, M.D., lead author of the study and a neurologist and medical fellow at Lilly Research Laboratories. “This study showed duloxetine reduced pain over a six-month period, making this the longest data analysis of duloxetine for the treatment of DPNP.”...
