Posology Duerta should be administered every 7th day. Patients aged 18 years and over The lowest Duerta dose (Duerta 5 microgram/hour transdermal patch) should be used as the initial dose. 5) as well as to the current general condition and medical status of the patient.
4). 5) as needed until analgesic efficacy with Duerta is attained. During the titration process, the dose may be adjusted every 3-days (72 hours). Thereafter, the 7-day dosing interval should be maintained. Subsequent dosage increases may then be titrated based on the need for supplemental pain relief and the patient’s analgesic response to the patch.
To increase the dose, a larger patch should replace the patch that is currently being worn, or a combination of patches should be applied in different places to achieve the desired dose. It is recommended that no more than two patches are applied at the same time, up to a maximum total dose of 40 microgram/hour Duerta.
2). Patients should be carefully and regularly monitored to assess the optimum dose and duration of treatment. 4). A Duerta dose reduction or discontinuation of Duerta treatment or treatment review may be indicated. Conversion from opioids Duerta can be used as an alternative to treatment with other opioids.
5) during titration, as required. Paediatric population The safety and efficacy of Duerta in children below 18 years of age has not been established. No data are available. Elderly No dosage adjustment of Duerta is required in elderly patients.
Renal impairment No special dose adjustment of Duerta is necessary in patients with renal impairment. Hepatic impairment There is no need for dosage adjustment of Duerta in patients with mild to moderate hepatic impairment. Buprenorphine is metabolised in the liver.
The intensity and duration of its action may be affected in patients with impaired liver function. Therefore, such patients should be carefully monitored during treatment with Duerta. Patients with severe hepatic impairment may accumulate buprenorphine during Duerta treatment.
Consideration of alternate therapy should be considered, and Duerta should be used with caution, if at all, in such patients. Method of administration Route of administration Transdermal patch to be worn for 7 days. The patch must not be divided or cut into pieces.

2) • Constipation Respiratory depression Significant respiratory depression has been associated with buprenorphine, particularly by the intravenous route. A number of overdose deaths have occurred when addicts have intravenously abused buprenorphine, usually with benzodiazepines concomitantly.
Additional overdose deaths due to ethanol and benzodiazepines in combination with buprenorphine have been reported. 9). Caution should be exercised when prescribing Duerta to patients known to have, or suspected of having, problems with drug or alcohol abuse or serious mental illness.
Concomitant use of opioids such as buprenorphine and sedative medicines such as benzodiazepines or related drugs may result in sedation, respiratory depression, coma and death. Because of these risks, concomitant prescribing with these sedative medicines should be reserved for patients for whom alternative treatment options are not possible.
If a decision is made to prescribe buprenorphine concomitantly with sedative medicines, the lowest effective dose should be used, and the duration of treatment should be as short as possible. The patients should be followed closely for signs and symptoms of respiratory depression and sedation.
5). 5). If concomitant treatment with other serotonergic agents is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases. Symptoms of serotonin syndrome may include mental-status changes, autonomic instability, neuromuscular abnormalities, and/or gastrointestinal symptoms.
If serotonin syndrome is suspected, a dose reduction or discontinuation of therapy should be considered depending on the severity of the symptoms. 1). Drug dependence, tolerance and potential for abuse For all patients, prolonged use of this product may lead to drug dependence (addiction), even at therapeutic doses.

4), the following directions of use should be followed: Duerta should be applied to non-irritated, intact skin of the upper outer arm, upper chest, upper back or the side of the chest, but not to any parts of the skin with large scars.
Duerta should be applied to a relatively hairless or nearly hairless skin site. If none are available, the hair at the site should be cut with scissors, not shaven. If the application site must be cleaned, it should be done with clean water only.
Soaps, alcohol, oils, lotions or abrasive devices must not be used. The skin must be dry before the patch is applied. Duerta should be applied immediately after removal from the sealed sachet. Following removal of the protective layer, the transdermal patch should be pressed firmly in place with the palm of the hand for approximately 30 seconds, making sure the contact is complete, especially around the edges.
If the edges of the patch begin to peel off, the edges may be taped down with suitable skin tape to ensure a 7 day period of wear. The patch should be worn continuously for 7 days. Bathing, showering, or swimming should not affect the patch.
If a patch falls off, a new one should be applied and worn for 7 days. Duration of administration Duerta should under no circumstances be administered for longer than absolutely necessary. If long-term pain treatment with Duerta is necessary in view of the nature and severity of the illness, then careful and regular monitoring should be carried out (if necessary with breaks in treatment) to establish whether and to what extent further treatment is necessary.
Treatment goals and Discontinuation Before initiating treatment with Duerta, a treatment strategy including treatment duration and treatment goals, and a plan for end of the treatment, should be agreed together with the patient, in accordance with pain management guidelines.
During treatment, there should be frequent contact between the physician and the patient to evaluate the need for continued treatment, consider discontinuation and to adjust dosages if needed. When a patient no longer requires therapy with Duerta, it may be advisable to taper the dose gradually to prevent symptoms of withdrawal.
4). After removal of the patch, buprenorphine serum concentrations decrease gradually and thus the analgesic effect is maintained for a certain amount of time. This should be considered when therapy with Duerta is to be followed by other opioids.
As a general rule, a subsequent opioid should not be […]
*In some cases delayed local allergic reactions (allergic contact dermatitis) occurred with marked signs of inflammation. g. laceration) are also possible in patients with fragile skin. Chronic inflammation may lead to long-lasting sequelae, such as post inflammatory hyper- and hypopigmentation, as well as dry and thick scaly skin lesions, which may closely resemble scars.
4). Drug dependence Repeated use of Duerta can lead to drug dependence, even at therapeutic doses. 4). After discontinuation of Duerta, withdrawal symptoms are uncommon. This may be due to the very slow dissociation of buprenorphine from the opioid receptors and to the gradual decrease of buprenorphine plasma concentrations (usually over a period of 30 hours after removal of the last patch).
Reporting of suspected adverse reactions Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
g. major depression). Additional support and monitoring may be necessary when prescribing for patients at risk of opioid misuse. A comprehensive patient history should be taken to document concomitant medications, including over-the-counter medicines and medicines obtained on-line, and past and present medical and psychiatric conditions.
Patients may find that treatment is less effective with chronic use and express a need to increase the dose to obtain the same level of pain control as initially experienced. Patients may also supplement their treatment with additional pain relievers.
These could be signs that the patient is developing tolerance. The risks of developing tolerance should be explained to the patient. Overuse or misuse may result in overdose and/or death. It is important that patients only use medicines that are prescribed for them at the dose they have been prescribed and do not give this medicine to anyone else.
Patients should be closely monitored for signs of misuse, abuse, or addiction. The clinical need for analgesic treatment should be reviewed regularly. Drug withdrawal syndrome Prior to starting treatment with any opioids, a discussion should be held with patients to put in place a withdrawal strategy for ending treatment with buprenorphine.
Drug withdrawal syndrome may occur upon abrupt cessation of therapy or dose reduction. When a patient no longer requires therapy, it is advisable to taper the dose gradually to minimise symptoms of withdrawal. Tapering from a high dose may take weeks to months.
The opioid drug withdrawal syndrome is characterised by some or all of the following: restlessness, lacrimation, rhinorrhoea, yawning, perspiration, chills, myalgia, mydriasis and palpitations. Other symptoms may also develop including irritability, agitation, anxiety, hyperkinesia, tremor, weakness, insomnia, anorexia, abdominal cramps, nausea, vomiting, diarrhoea, increased blood pressure, increased respiratory rate or heart rate.
If women take this drug during pregnancy, there is a risk that their newborn infants will experience neonatal withdrawal syndrome. Hyperalgesia Hyperalgesia may be diagnosed if the patient on long-term opioid therapy presents with increased pain.
This might be qualitatively and anatomically distinct from pain related to disease progression or to breakthrough pain resulting from development of opioid tolerance. Pain associated with hyperalgesia tends to be more diffuse than the pre-existing pain and less defined in quality.
Symptoms of hyperalgesia may resolve with a reduction of opioid dose. Sleep-related breathing disorders Opioids can cause sleep-related breathing disorders including central sleep apnoea (CSA) and sleep-related hypoxemia. Opioid use increases […]
