New Data Show Duloxetine Maintained Pain Reduction for More Than Six Months in Patients With Diabetic Peripheral Neuropathic Pain
Indianapolis (ots/PRNewswire) -
- Study with duloxetine evaluating long-term pain reduction in treatment of DPNP is first to exceed three months
Duloxetine hydrochloride maintained pain reduction in the treatment of diabetic peripheral neuropathic pain (DPNP) for more than six months,(1) according to new data presented today 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.(1) 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."
During the course of the eight-week acute therapy and 26-week maintenance therapy periods, the most common treatment-emergent adverse events (those occurring in more than 5 percent of patients) for those taking 60 mg of duloxetine were nausea, somnolence, hyperhydrosis (excessive sweating), dry mouth, anorexia, asthenia (weakness), fatigue and headache.(2)
An estimated 246 million adults worldwide suffer from diabetes.(3) By 2025, that number is expected to rise to 380 million, according to the International Diabetes Federation.(3) Although all diabetics are at risk for DPNP, those most likely to develop the condition are long-term sufferers whose blood-sugar levels have not been adequately controlled, who have high blood pressure or are overweight.(4) An estimated 17.2 million to 49.2 million patients with diabetes have been diagnosed with DPNP.(5)
Duloxetine is a serotonin and norepinephrine reuptake inhibitor (SNRI). Although it does not treat the underlying nerve damage caused by DPNP, duloxetine does help relieve the intense pain often associated with the disorder.(6) Scientists believe it does this by increasing levels of serotonin and norepinephrine -- two neurotransmitters believed to regulate a person's sensitivity to pain. Increasing these levels in a balanced way is thought to improve the body's natural ability to regulate pain by modulating the descending pain pathways in the central nervous system.
In Europe, duloxetine is approved for the treatment of DPNP, major depressive disorder MDD and generalised anxiety disorder (GAD).
Duloxetine is approved in various countries outside of Europe for the management of DPNP, for the treatment of MDD, for the treatment of GAD and for the management of fibromyalgia.
Notes to Editors:
About Diabetic Peripheral Neuropathic Pain
Approximately half of those with diabetes have some form of nerve damage, or neuropathy, but not all will develop symptoms. While nerve problems can occur at any time, the highest rates are among those who have had diabetes for at least 25 years.(4) Symptoms can include numbness, tingling or pain and weakness in the toes, feet, legs, hands, arms and fingers. These symptoms are often worse at night.(4)
While duloxetine's mechanism of action in humans is not fully known, it is believed to affect both serotonin and norepinephrine/noradrenaline mediated nerve signalling in the brain and the spinal cord. Based on pre-clinical studies, duloxetine is a reuptake inhibitor of serotonin and norepinephrine/noradrenaline. Scientists believe its effect on pain perception is due to increasing the activity of serotonin and norepinephrine in the central nervous system.
Duloxetine is approved for the treatment of major depressive disorder and diabetic peripheral neuropathic pain in many countries and is approved in some countries for the treatment of stress urinary incontinence and generalised anxiety disorder. Duloxetine is approved only for adults age 18 and over. There is a possibility of an increased risk of suicidal thoughts or behaviour in children and young adults treated with antidepressants. Patients should call their doctor right away if they experience worsening depression symptoms, unusual changes in behaviour or thoughts of suicide, especially at the beginning of treatment or after a change in dose.
Patients taking duloxetine may experience dizziness or fainting upon standing. The most common side effects of duloxetine include:
@@start.t1@@ -- for depression: nausea, dry mouth, headache, insomnia and diarrhea
-- for diabetic peripheral neuropathic pain: nausea, somnolence
(sleepiness), fatigue, headache and dizziness
-- for generalised anxiety disorder: nausea, fatigue, dry mouth,
drowsiness, constipation, insomnia, decreased appetite, hyperhydrosis,
decreased libido, vomiting, ejaculation delay and erectile dysfunction.
-- for stress urinary incontinence: nausea, dry mouth and fatigue@@end@@
This is not a complete list of side effects.
Duloxetine is contraindicated in patients who are allergic to it, who have liver disease resulting in hepatic impairment, who are taking a monoamine oxidase inhibitor (MAOI), fluvoxamine, ciprofloxacin or enoxacine or who have severe kidney disease. The initiation of treatment with duloxetine also is contraindicated in patients with uncontrolled hypertension that could expose patients to a potential risk of hypertensive crisis.
