Chronic pulmonary disease Durogesic DTrans may have more severe adverse effects in patients with chronic obstructive or other pulmonary disease. Fentanyl crosses the blood-brain barrier easily. Oral doses are those recommended when changing from a parenteral to an oral dtraans. Durogesic DTrans contains a medicine called fentanyl.

Anaphylactic shock, Anaphylactic reaction, Anaphylactoid reaction. Table 3 is for adult patients who are on a stable, and well-tolerated, opioid regimen conversion ratio of oral morphine to transdermal fentanyl approximately equal to Fentanyl concentrations may increase if the skin temperature increases see section 5.
Enter email address Submit. In patients currently taking opioid analgesics, the starting dose of Durogesic DTrans should be based on the daily dose of the prior opioid. Serotonin syndrome may include durkgesic changes e. Company contact details Janssen-Cilag Ltd.
If concomitant use of Durogesic DTrans with a CNS depressant is clinically necessary, prescribe the lowest effective dosages and minimum duration for both drugs, and follow patients closely for signs of respiratory depression and sedation.
Elderly patients should be observed carefully and the dose should be individualised based upon the status of the patient see sections 4.

These actions can be followed by administration of a specific opioid antagonist such as naloxone. If concomitant use of Durogesic DTrans with a CYP3A4 inhibitor cannot be avoided, close monitoring for signs or symptoms of increased or prolonged therapeutic effects and adverse effects of fentanyl in particular respiratory depression is warranted, and the Durogesic DTrans dosage must be reduced or interrupted as deemed necessary see section 4.
In a study conducted with Durogesic DTrans, healthy elderly subjects had fentanyl pharmacokinetics which did not differ significantly from healthy young subjects although peak serum concentrations tended to be lower and mean half-life values were prolonged to dirogesic 34 hours.
If analgesia is insufficient during the first application only, the Durogesic DTrans patch may be replaced after 48 hours with a patch of the same dose, or the dose may be increased after 72 hours.
There is a high inter-subject variability in fentanyl pharmacokinetics, in the relationships between fentanyl concentrations, therapeutic and adverse effects, and in opioid tolerance. Its primary therapeutic actions are analgesia and sedation. Skin does not appear to metabolise fentanyl delivered transdermally.

Children Long term management dueogesic severe chronic pain in children from 2 years of age who are receiving opioid therapy. Recommended starting dosage durogeskc Durogesic DTrans based upon daily oral morphine dose for patients who have a need for opioid rotation or for clinically less stable patients: Then they should be safely discarded by putting them back into the original sachet and stored out of sight and reach of other people, especially children, until safely disposed.
Therefore, the concomitant use of Durogesic DTrans and CYP3A4 inhibitors is not recommended unless the benefits outweigh the increased risk of adverse effects. Dtrnas patch is marked: Patients can then switch to Durogesic DTrans. An optimal therapeutic concentration range of fentanyl can therefore not be established.
Fentanyl may produce bradycardia and should therefore be administered with caution to patients with bradyarrhythmias.
Hypotension Opioids may cause hypotension, especially in patients with acute hypovolaemia. It also crosses the placenta and is excreted in breast milk.
After an increase in dose, it may take up to 6 days for the patient to reach equilibrium on the new dose level.

Posology Durogesic DTrans doses should be individualised based upon the status of the patient and should be assessed at regular intervals after application.
When prescribing this medicine, patients should be told: The major metabolite, norfentanyl, and other metabolites are inactive. Careful monitoring should be continued until stable drug effects are achieved. If serotonin syndrome is suspected, treatment with Durogesic DTrans should be discontinued.
Pharmacology is a study guide providing an account of drug action, as well as dealing with molecular pharmacology at a more advanced level. Extra caution should be used in patients with chronic constipation.
