Overview
This is a summary of the European public assessment report (EPAR). It explains how the Committee for Medicinal Products for Human Use (CHMP) assessed the studies performed, to reach its recommendations on how to use the medicine.
If you need more information about your medical condition or your treatment, read the package leaflet (also part of the EPAR) or contact your doctor or pharmacist. If you want more information on the basis of the CHMP recommendations, read the scientific discussion (also part of the EPAR).
Cymbalta is a medicine that contains the active substance duloxetine. It is available as gastroresistant capsules (white and blue: 30 mg; green and blue: 60 mg). ‘Gastroresistant’ means that the capsules’ contents pass through the stomach without being broken down until they reach the intestine.
This prevents the active substance being destroyed by the acid in the stomach.
Cymbalta is used to treat adults with the following diseases:
- major depression;
- pain due to diabetic peripheral neuropathy (damage to the nerves in the extremities that can occur in patients with diabetes);
- generalised anxiety disorder (long-term anxiety or nervousness about everyday matters).
The medicine can only be obtained with a prescription.
For major depression, the recommended dose of Cymbalta is 60 mg once a day. A response is usually seen in two to four weeks. In patients who respond to Cymbalta, treatment should continue for several months to prevent the disease coming back, or for longer in patients who have had repeated periods of depression in the past.
For diabetic neuropathic pain, the recommended dose is 60 mg per day but some patients may need a higher dose of 120 mg per day. The response to treatment should be assessed regularly.
For generalised anxiety disorder, the recommended starting dose is 30 mg once a day, but the dose can be increased to 60, 90 or 120 mg depending on the patient’s response. Most patients will need to take 60 mg per day. Patients who also have major depression should start with 60 mg once a day. In patients who respond to Cymbalta, treatment should continue for several months, to prevent the disorder coming back.
The dose of Cymbalta should be reduced gradually when stopping treatment.
The active substance in Cymbalta, duloxetine, is a serotonin-noradrenaline re-uptake inhibitor. It works by preventing the neurotransmitters 5-hydroxytryptamine (also called serotonin) and noradrenaline from being taken back up into nerve cells in the brain and spinal cord.
Neurotransmitters are chemicals that allow nerve cells to communicate with one another. By blocking their re-uptake, duloxetine increases the amount of these neurotransmitters in the spaces between these nerve cells, increasing the level of communication between the cells. Since these neurotransmitters are involved in maintaining high mood and reducing the sensation of pain, blocking their re-uptake into nerve cells can improve the symptoms of depression, anxiety and neuropathic pain.
For major depression, Cymbalta has been compared with placebo (a dummy treatment) in eight main studies involving a total of 2,544 patients. Six of the studies looked at the treatment of depression and measured the change in symptoms over up to six months. The other two studies looked at how long it took for symptoms to return in patients who had initially responded to Cymbalta, including 288 patients with a history of repeated episodes of depression for up to five years.
For neuropathic pain, Cymbalta has been compared with placebo in two 12-week studies in 809 diabetic adults. The main measure of effectiveness was the change in the severity of pain each week. For generalised anxiety disorder, Cymbalta has been compared with placebo in five studies involving a total of 2,337 patients. Four studies looked at the treatment of the disorder by measuring the reduction in symptoms after nine to 10 weeks. The fifth study looked at how long it took for symptoms to return in 429 patients who had initially responded to Cymbalta.
Although the results of the depression studies varied, Cymbalta was more effective than placebo in four of the studies. In the two studies where the approved dose of Cymbalta was compared with placebo, Cymbalta was more effective. It also took longer for symptoms to return in patients taking Cymbalta than in those taking placebo.
For the treatment of diabetic neuropathic pain, Cymbalta was more effective at reducing pain than placebo. In both studies, pain reduction was seen from the first week of treatment for up to 12 weeks.
For generalised anxiety disorder, Cymbalta was also more effective than placebo at treating the disorder and preventing symptoms returning.
The most common side effects with Cymbalta (seen in more than 1 patient in 10) are nausea (feeling sick), headache, dry mouth, somnolence (sleepiness) and dizziness. Most of these were mild or moderate, starting early in treatment and getting milder as treatment continued. For the full list of all side effects reported with Cymbalta, see the package leaflet.
Cymbalta should not be used in people who may be hypersensitive (allergic) to duloxetine or any of the other ingredients. Cymbalta must not be used together with monoamine-oxidase inhibitors (another group of antidepressants), fluvoxamine (another antidepressant), or ciprofloxacin or enoxacin (types of antibiotic). Cymbalta must also not be used in patients with certain types of liver disease or patients with severe kidney disease. Treatment must not be started in patients with uncontrolled hypertension (high blood pressure), because of a risk of hypertensive crisis (sudden, dangerously high blood pressure). As with other antidepressants, isolated cases of suicidal thoughts and behaviour have been seen in patients taking Cymbalta, particularly in the first few weeks of treatment for depression. Any patients taking Cymbalta who have distressing thoughts or experiences at any time should tell their doctor immediately.
The Committee for Medicinal Products for Human Use (CHMP) decided that Cymbalta’s benefits are greater than its risks and recommended that it be given marketing authorisation.
The European Commission granted a marketing authorisation valid throughout the European Union for Cymbalta to Eli Lilly Nederland BV on 17 December 2004. The marketing authorisation is valid for an unlimited period.
