Durogesic should only be used in patients who are already receiving opioid therapy, who have demonstrated opioid tolerance. :שינויים בעלון לרופא DESCRIPTION ……………. The composition per unit area of all system size is identical. Durogesic® is a rectangular transparent unit comprising a protective liner and two functional layers. Proceeding from the outer surface toward the surface adhering to skin, these layers are: 1) a backing layer of polyester/ethyl vinyl acetate film; 2) a drug-in-adhesive layer. Before use, a protective liner covering the adhesive layer is removed and discarded. The active component of the system is fentanyl. The remaining components are pharmacologically inactive. CLINICAL PHARMACOLOGY Pharmacology ……………… In addition to analgesia, alterations in mood, euphoria, dysphoria, and drowsiness commonly occur. Fentanyl depresses the respiratory centers, depresses the cough reflex, and constricts the pupils. Analgesic blood levels concentrations of fentanyl may cause nausea and vomiting directly by stimulating the chemoreceptor trigger zone, but nausea and vomiting are significantly more common in ambulatory than in recumbent patients, as is postural syncope. ………………. 1 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 Pharmacokinetics Absorption DUROGESIC provides continuous systemic delivery of fentanyl during the 72-hour application period. Fentanyl is released at a relatively constant rate, determined by the copolymer release membrane and the diffusion of fentanyl through the skin layers. Fentanyl is released at a relatively constant rate. The concentration gradient existing between the matrix and the lower concentration in the skin drives drug release After initial DUROGESIC application, serum fentanyl concentrations increase gradually, generally leveling off between 12 and 24 hours and remaining relatively constant for the remainder of the 72-hour application period. The serum fentanyl ® concentrations attained are proportional to the DUROGESIC patch size. After repeated 72-hour applications, patients reach a steady-state serum concentration that is maintained during subsequent applications of a patch of the same size. By the end of the second 72-hour application, a steady-state serum concentration is reached and is maintained during subsequent applications of a patch of the same size. A pharmacokinetic model has suggested that serum fentanyl concentrations may increase by 14% (range 0- 26%) if a new patch is applied after 24 hours rather than the recommended 72-hour application. Distribution The plasma-protein binding of fentanyl is about 84%. Metabolism Fentanyl is a high clearance drug and is rapidly and extensively metabolized primarily by CYP3A4 in the liver. The major metabolite, norfentanyl, is inactive. Skin does not appear to metabolize fentanyl delivered transdermally. This was determined in a human keratinocyte cell assay and in clinical studies in which 92% of the dose delivered from the system was accounted for as unchanged fentanyl that appeared in the systemic circulation. Elimination After DUROGESIC is removed, serum fentanyl concentrations decline gradually, falling about 50% in about 17 (range 13-22) hours following a 24hour application. Following a 72-hour application, the mean terminal half-life ranges from 20-25 20-27 hours. Continued absorption of fentanyl from the skin accounts for a slower disappearance of the drug from the serum than is seen after an IV infusion, where the apparent half-life is approximately 7 (range 3-12) hours. Elderly, cachectic, or debilitated patients may have a reduced clearance of fentanyl and, therefore, the drug may have a prolonged terminal half-life in them. Adjusting for body weight, clearance in pediatric patients was about 20% higher than that in adults. These findings have been taken into consideration in determining the dosing recommendations for pediatric patients. 0 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 Fentanyl is a high clearance drug and is rapidly and extensively metabolized primarily by CYP3A4 in the liver. Within 72 hours of IV fentanyl administration, approximately Around 75% of the fentanyl dose is excreted into the urine, mostly as metabolites, with less than 10% as unchanged drug. About 9% of the dose is recovered in the feces, primarily as metabolites. Mean values for unbound fractions of fentanyl in plasma are estimated to be between 13 and 21%. Special Populations: Elderly Data from intravenous studies with fentanyl suggest that elderly patients may have reduced clearance, a prolonged half-life, and they may be more sensitive to the drug than younger patients. In a study conducted with ® DUROGESIC , 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 approximately 34 hours. Elderly patients should be observed carefully for signs of fentanyl toxicity and the dose reduced if necessary (Special warnings and special precautions). Children DUROGESIC® was not studied in children under 2 years of age. Studies conducted in older children found that when adjusting for body weight, clearance in pediatric patients was about 20% higher than that in adults. These findings have been taken into consideration in determining the dosing recommendations for pediatric patients. DUROGESIC® should be administered only to opioid-tolerant children age 2 years or older (see Posology and method of administration and Special warnings and special precautions). Hepatic Impairment In a study conducted with patients with hepatic cirrhosis, the ® pharmacokinetics of a single 50 g/hr application of DUROGESIC were assessed. Although tmax and t1/2 were not altered, the mean plasma Cmax and AUC values increased by approximately 35% and 73%, respectively, in these patients. Patients with hepatic impairment should be observed carefully for signs of fentanyl toxicity and the dose of DUROGESIC® reduced if necessary (see Special warnings and special precautions). Renal Impairment Data obtained from a study administering IV fentanyl in patients undergoing renal transplantation suggest that the clearance of fentanyl may be reduced in this patient population. If patients with renal impairment receive DUROGESIC®, they should be observed carefully for signs of fentanyl toxicity and the dose reduced if necessary (see Special warnings and special precautions). 3 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 Drug interactions The interaction between ritonavir , a CYP3A4 inhibitor, and fentanyl was investigated in eleven healthy volunteers in a randomized crossover study. Subjects received oral ritonavir or placebo for 3 days. The ritonavir dose was 200 mg tid on Day 1 and 300 mg tid on Day 2 followed by one morning dose of 300 mg on Day 3. On Day 2, fentanyl was given as a single IV dose at 5 mcg/kg two hours after the afternoon dose of oral ritonavir or placebo. Naloxone was administered to counteract the side effects of fentanyl. The results suggested that ritonavir might decrease the clearance of fentanyl by 67%, resulting in a 174% (range 52%-420%) increase in fentanyl AUC0-∞. Coadministration of ritonavir in patients receiving DUROGESIC has not been studied; however, an increase in fentanyl AUC is expected. (See BOX WARNING, WARNINGS, PRECAUTIONS and DOSAGE AND ADMINISTRATION.) Fentanyl is metabolized mainly via the human cytochrome P450 3A4 isoenzyme system (CYP3A4), therefore, potential interactions may occur when Durogesic®is given concurrently with agents that affect CYP3A4 activity. Coadminstration with agents that induce CYP3A4 activity may reduce the efficacy of Durogesic®. The concomitant use of transdermal fentanyl with all CYP3A4 inhibitors (such as ritonavir, ketoconazole, itraconazole, troleandomycin, clarithromycin, nelfinavir, nefazadone, amiodarmone, amprenavir, aprepitant, diltiazem, erythromycin, fluconazole, fosamprenavir, and verapamil) may result in an increase in fentanyl plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. Patients receiving Durogesic® and any CYP3A4 inhibitor should be carefully monitored for an extended period of time and dosage adjustments should be made if warranted (see BOX WARNING, WARNINGS, PRECAUTIONS,and DOSAGE AND ADMINISTRATION for further information). WARNINGS ® Durogesic patches are intended for transdermal use (on intact skin) only. Do not use ® damaged or cut DUROGESIC patches. Do not use a DUROGESIC® patch if the pouch seal is broken or the patch is cut, damaged, or changed in any way. The safety of DUROGESIC® (fentanyl transdermal system) has not been established in children under 2 years of age. . DUROGESIC is ONLY for use in patients who are already tolerant to opioid therapy of comparable potency. Use in non-opioid tolerant patients may lead ® to fatal respiratory depression. Overestimating the DUROGESIC dose when converting patients from another opioid medication can result in fatal overdose with the first dose. The mean elimination half-life of DUROGESIC® is approximately 20-27 hours.17 hours. Therefore, patients who have experienced serious adverse events, including overdose, will require monitoring for at least 24 hours after DUROGESIC® removal since serum fentanyl concentrations decline gradually and reach an approximate 50% reduction in serum concentrations 20-27 17 hours after system removal. 4 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 DUROGESIC® should be prescribed only by persons knowledgeable in the continuous administration of potent opioids, in the management of patients receiving potent opioids for treatment of pain, and in the detection and management of hypoventilation including the use of opioid antagonists. In order to ensure the continuity of different products of fentanyl transdermal patches in individual patients it should be emphasized that if patients are changed from one fentanyl transdermal patch to another it should be done only with specific counseling and monitoring from their healthcare professional. All patients and their caregivers should be advised to avoid exposing the ® DUROGESIC application site and surrounding area to direct external heat sources, such as heating pads or electric blankets, heat or tanning lamps, saunas, hot tubs, and heated water beds, whirpool spa bath, intensive sunbathing and hot water bottles prolonged hot baths, etc., while wearing the system. Patients should be advise against taking hot baths or sunbathing.There is a potential for temperaturedependent increases in fentanyl released from the system resulting in possible overdose and death. A clinical pharmacology trial conducted in healthy adult subjects has shown that the application of heat over the DUROGESIC system increased mean fentanyl AUC values by 120% and mean Cmax values by 61%. Based on a pharmacokinetic model, serum fentanyl concentrations could theoretically increase by approximately one-third for patients with a body temperature of 40°C (104°F) due to temperature-dependent increases in fentanyl released from the system and increased skin permeability. Patients wearing DUROGESIC® systems who develop fever or increased core body temperature due to strenuous exertion should be monitored for opioid side effects and the DUROGESIC®dose should be adjusted if necessary. …………………….. Hypoventilation (Respiratory Depression) Serious or life-threatening hypoventilation may occur at any time during the use of DUROGESIC® especially during the initial 24-72 hours following initiation of therapy and following increases in dose. Because significant amounts of fentanyl continue to be are absorbed from the skin for 17 20-27 hours or more after the patch is removed, hypoventilation may persist beyond the removal of DUROGESIC®. ………………………… Interactions with other CNS Depressants The concomitant use of Durogesic® (fentanyl transdermal system) with other central nervous system depressants, including but not limited to other opioids, sedatives, hypnotics, tranquilizers (e.g., benzodiazepines), general anesthetics, phenothiazines, skeletal muscle relaxants, sedating antihistamins and alcohol, may cause respiratory depression, hypotension, and profound sedation or potentially result in coma.or death When such combined therapy is contemplated, the dose of one or both agents should be significantly reduced and special patient care and observation is required. 5 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 Interactions with Alcohol and Drugs of Abuse Fentanyl may be expected to have additive CNS depressant effects when used in conjunction with alcohol, other opioids, or illicit drugs that cause central nervous system depression. Interactions with CYP3A4 Inhibitors The concomitant use of Durogesic® with All potent cytochrome P450 3A4 inhibitors (such as ritonavir, ketoconazole, itraconazole, troleandomycin, clarithromycin, nelfinavir, nefazodone, , and amiodarone, amprenavir, aprepitant, diltiazem ,erythromycin, fluconazole, fosamprenavir, grapefruit juice and verapamil) may result in an increase in fentanyl plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. Therefore, the concomitant use of transdermal fentanyl and CYP3A4 inhibitors is not recommended unless the patient is closely monitored. Patients, especially those who are receiving.Durogesic® and any potent CYP3A4 inhibitor should be carefully monitored for an extended period of time and dosage adjustments should be made if warranted. (See BOX WARNING, CLINICAL PHARMACOLOGY – Drug Interactions, PRECAUTIONS and DOSAGE AND ADMINISTRATION for further information.) PRECAUTIONS …………………. Cardiac Disease Fentanyl may produce bradycardia. Fentanyl should be administered with caution to patients with bradyarrhythmias. Hepatic Disease and Renal Dedease Because fentanyl is metabolized to inactive metabolites in the liver, hepatic disease impairment might delay its elimination. In patients with hepatic cirrhosis, the pharmacokinetics of a single application of DUROGESIC® were not altered although serum concentrations tended to be higher in these patients. If patients with hepatic impairment receive Durogesic they should be observed carefully for signs of fentanyl toxicity and the dose of DUROGESIC® reduced if necessary. Renal Disease Less than 10% of fentanyl is excreted unchanged by the kidney and, unlike morphine, there are no known active metabolites eliminated by the kidney. Data obtained with intravenous fentanyl in patients with renal failure suggest that the volume of distribution of fentanyl may be changed by dialysis. This may affect serum concentrations. If patients with renal impairment receive DUROGESIC®, they should be observed carefully for signs of fentanyl toxicity and the dose reduced if necessary. Patients with Fever/External Heat Based on a pharmacokinetic model, serum fentanyl concentrations could theoretically increase by approximately one-third for patients with a body temperature of 40°C (104°F) due to temperature-dependent increases in fentanyl release from the system and increased skin permeability. Therefore, patients 6 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 wearing DUROGESIC® systems who develop fever should be monitored for opioid side effects and the DUROGESIC® dose should be adjusted if necessary. All patients and their caregivers should be advised to avoid exposing the DUROGESIC® application site to direct external heat sources, such as heating pads or electric blankets, heat lamps, saunas, hot tubs, whirpool spa bath, heated water beds, intensive sunbathing and hot water bottles etc., while wearing the system. There is a potential for temperature-dependent increases in fentanyl release from the system. …………………………. Physical Dependence Physical dependence is a state of adaptation that is manifested by an opioid specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level concentration of the drug, and/or administration of an antagonist. The opioid abstinence or withdrawal syndrome is characterized by some or all of the following: restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, piloerection, myalgia, mydriasis, irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate. In general, opioids should not be abruptly discontinued (see DOSAGE AND ADMINISTRATION – Discontinuation of DUROGESIC ). Ambulatory Patients ……………………….. Effects on ability to drive and use machines DUROGESIC® may impair mental and/or physical ability required for the performance of potentially hazardous tasks such as driving a car or operating machinery. Information for Patients ® A patient information sheet is included in the package of DUROGESIC patches dispensed to the patient. …………………. 1. Patients should be advised that DUROGESIC® should be applied immediately upon removal from the sealed pouch package. To remove the patch from the protective pouch, locate the pre-cut notch (indicated by an arrow on the patch label) along the edge of the seal. Fold the pouch at the notch, then carefully tear the pouch material. Further open the pouch along both sides, folding the pouch open like a book. The release liner for the matrix is slit. Fold the patch in the middle and remove each half of the liner separately. Avoid touching the adhesive side of the patch. Additionally the patient should be advised of the following: The DUROGESIC patch should not be used if the seal is broken, or if it is altered, cut, or damaged in any way prior to application. Apply the patch to the skin by applying light pressure with the palm of the hand for about 30 seconds. Make certain that the edges of the patch are adhering properly. Then wash hands with clean water. ® 7 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 The patch should not be folded so that only part of the patch is exposed. and after removal of the protective liner. Additionally the patient should be advised of the following: The DUROGESIC® patch should not be used if the pouch seal is broken, or if the patch is cut, damaged, or changed in any way. The transdermal patch should be pressed firmly in place with the palm of the hand for 30 seconds, making sure the contact is complete, especially around the edges. The patch should not be folded so that only part of the patch is exposed. 5. Patients should be advised that the dose of DUROGESIC® or the number of patches applied to the skin should NEVER be adjusted without the prescribing healthcare professional’s instruction. 6. Patients should be advised that while wearing the patch, they should avoid exposing the DUROGESIC® application site and surrounding area to direct external heat sources, such as: heating pads, electric blankets, heat or tanning lamps, saunas, hot tubs or hot baths , and intensive sunbathing heated water beds, etc. whirpool spa bath hot water bottles 7. Patients should also be advised that there is of a potential for temperaturedependent increase in fentanyl release from the patch that could result in an overdose of fentanyl; therefore, if patients who develop a high fever or increased body temperature due to strenuous exertion while wearing the patch they should contact their physician. 8. Patients should be advised that if the patch falls off before 72 hours a new patch may be applied to a different skin site. 8. Patients should be advised to fold (so that the adhesive side adheres to itself) and ® immediately flush down the toilet used DUROGESIC patches after removal from the skin. 9. Do not use soap, alcohol, or other chemicals, because these products may increase the ability of fentanyl to go through the skin. ® 10. Patients should be advised that the dose of DUROGESIC should NEVER be adjusted without the prescribing health care professional’s instruction. …………… 8 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 Drug Interactions Agents Affecting Cytochrome P450 3A4 Isoenzyme System Fentanyl is metabolized mainly via the human cytochrome P450 3A4 isoenzyme ® system (CYP3A4), therefore potential interactions may occur when DUROGESIC is given concurrently with agents that affect CYP3A4 activity. Coadminstration with ® agents that induce 3A4 activity may reduce the efficacy of DUROGESIC . The concomitant use of transdermal fentanyl with all CYP3A4 inhibitors ( such as such as ritonavir, or other potent 3A4 inhibitors such as ketoconazole, itraconazole, troleandomycin, clarithromycin, nelfinavir, nefazodone, , and amiodarone, amprenavir, aprepitant, diltiazem ,erythromycin, fluconazole, fosamprenavir, and verapamil) may result in an increase in fentanyl plasma concentrations (see BOX WARNING, CLINICAL PHARMACOLOGY – Drug Interactions , WARNINGS, and DOSAGE AND ADMINISTRATION). The concomitant use of other CYP3A4 inhibitors such as diltiazem and erythromycin with transdermal fentanyl may also result in an increase in fentanyl plasma concentrations, which could increase or prolong adverse drug effects and may cause serious fatal respiratory depression. In this situation, special patient care and observation are appropriate. Patients receiving DUROGESIC® and any CYP3A4 inhibitor should be carefully monitored for an extended period of time, and dosage adjustments should be made if warranted (see BOX WARNING, CLINICAL HARMACOLOGY – Drug Interactions, WARNINGS, and DOSAGE AND ADMINISTRATION for further information). Central Nervous System Depressants The concomitant use of DUROGESIC® (fentanyl transdermal system) with other central nervous system depressants, including but not limited to other opioids, sedatives, hypnotics, tranquilizers (e.g., benzodiazepines), general anesthetics, phenothiazines, skeletal muscle relaxants, sedating antihistamins and alcohol, may cause respiratory depression, hypotension, and profound sedation, or potentially result in coma or death. When such combined therapy is contemplated, the dose of one or both agents should be significantly reduced and special patient care and observation is required. MAOI Inhibitors ® DUROGESIC is not recommended for use in patients who require the concomitant administration of an MAOI or those who received MAOI within 14 days. Severe and unpredictable interactions with MAOIs, involving the potentiation of opiate effects or the potentiation of serotoninergic effects, ® have been reported. Therefore, DUROGESIC should not be used within 14 days after discontinuation of treatment with MAOIs. Carcinogenesis, Mutagenesis, and Impairment of Fertility In a two-year carcinogenicity study conducted in rats, fentanyl was not associated with an increased incidence of tumors at subcutaneous doses up to 33 μg/kg/day in males or 100 9 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 μg/kg/day in females (0.16 and 0.39 times the human daily exposure obtained via the 100 mcg/h patch based on AUC0-24h comparison). Studies in animals to evaluate the carcinogenic potential of fentanyl HCl have not been conducted. ……………………….. There are no adequate and well-controlled studies in pregnant women although fentanyl as an IV anesthetic has been found to cross the placenta in early human pregnancies.. DUROGESIC® should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Nonteratogenic Effects Neonatal withdrawal syndrome has been reported in newborn infants with chronic maternal use of Durogesic® during pregnancy. Chronic maternal treatment with fentanyl during pregnancy has been associated with transient respiratory depression, behavioral changes, or seizures characteristic of neonatal abstinence syndrome in newborn infants. There have been very rare reports of newborn infants experiencing neonatal withdrawal syndrome when mothers chronically used Durogesic® during pregnancy. …………………………….. Labor and Delivery Use of Durogesic ® during childbirth is not recommended because Durogesic should not be used in the management of acute or postoperative pain. Moreover, because Fentanyl readily passes across the placenta to the fetus the use of Durogesic® during childbirth might result in respiratory depression in the newborn infant. ; therefore, DUROGESIC® is not recommended for analgesia during labor and delivery. Nursing Mothers Fentanyl is excreted in human milk; therefore, DUROGESIC® is not recommended for use in nursing women because of the possibility of effects in their infants. Pediatric Use The safety of DUROGESIC® was evaluated in three open-label trials in 291 pediatric patients with chronic pain, 2 years of age through 18 years of age. Starting doses of 25 mcg/h and higher were used by 181 patients who had been on prior daily opioid doses of at least 45 mg/day of oral morphine or an equianalgesic dose of another opioid. Initiation of DUROGESIC® therapy in pediatric patients taking less than 60 mg/day of oral morphine or an equianalgesic dose of another opioid has not been evaluated in controlled clinical trials. Approximately 90% of ® the total daily opioid requirement (DUROGESIC plus rescue medication) was provided by ® DUROGESIC DUROGESIC® was not studied in children under 2 years of age. To guard against accidental ingestion by children, use caution when choosing the application site for DUROGESIC® (see DOSAGE AND ADMINISTRATION) and monitor adhesion of the system closely. Geriatric Use Information from a pilot study of the pharmacokinetics of IV fentanyl in geriatric patients (N=4) indicates that the clearance of fentanyl may be greatly decreased in the population above the age of 60. The relevance of these findings to DUROGESIC (fentanyl transdermal system) is unknown 12 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 at this time. Data from intravenous studies with fentanyl suggest that elderly patients may have reduced clearance, a prolonged half-life, and they may be more sensitive to the drug than younger patients. If elderly patients receive DUROGESIC®, they should be observed carefully for signs of fentanyl toxicity and the dose reduced if necessary (see Pharmacokinetic properties). Since elderly, cachectic, or debilitated patients may have altered pharmacokinetics due to poor fat stores, muscle wasting, or altered clearance, they should not be started on DUROGESIC® doses higher than 25 mcg/h unless they are already tolerating an around-the-clock opioid at a dose and potency comparable to DUROGESIC®-25 (see DOSAGE AND ADMINISTRATION). Respiratory depression is the chief hazard in elderly or debilitated patients, usually following large initial doses in non-tolerant patients, or when opioids are given in conjunction with other agents that depress respiration. DUROGESIC® should be used with caution in elderly, cachectic, or debilitated patients as they may have altered pharmacokinetics due to poor fat stores, muscle wasting or altered clearance (see DOSAGE AND ADMINISTRATION). ADVERSE REACTIONS In post-marketing experience, deaths from hypoventilation due to inappropriate use of DUROGESIC® (fentanyl transdermal system) have been reported (see BOX WARNING and CONTRAINDICATIONS). Pre-Marketing Clinical Trial Experience Although DUROGESIC® use in post-operative or acute pain and in patients who are not opioid-tolerant is CONTRAINDICATED, the safety of DUROGESIC® was originally evaluated in 357 post-operative adult patients for 1 to 3 days and 153 cancer patients for a total of 510 patients. The duration of DUROGESIC® use ® varied in cancer patients; 56% of patients used DUROGESIC for over 30 days, 28% continued treatment for more than 4 months, and 10% used DUROGESIC® for more than 1 year. Hypoventilation was the most serious adverse reaction observed in 13 (4%) postoperative patients and in 3 (2%) of the cancer patients. Hypotension and hypertension were observed in 11 (3%) and 4 (1%) of the opioid-naive patients. Various adverse events were reported; a causal relationship to DUROGESIC® was not always determined. The frequencies presented here reflect the actual frequency of each adverse effect in patients who received DUROGESIC®. There has been no attempt to correct for a placebo effect, concomitant use of other opioids, or to subtract the frequencies reported by placebo-treated patients in controlled trials. Adverse reactions reported in 153 cancer patients at a frequency of 1% or greater are presented in Table 1; similar reactions were seen in the 357 post-operative patients. ® In the pediatric population, the safety of DUROGESIC has been evaluated in 291 patients with chronic pain 2-18 years of age. The duration of DUROGESIC® use 11 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 varied; 20% of pediatric patients were treated for ≤ 15 days; 46% for 16-30 days; 16% for 31-60 days; and 17% for at least 61 days. Twenty-five patients were treated with DUROGESIC® for at least 4 months and 9 patients for more than 9 months. There was no apparent pediatric-specific risk associated with DUROGESIC® use in children as young as 2 years old when used as directed. The most common adverse events were fever (35%), vomiting (33%), and nausea (24%). Adverse events reported in pediatric patients at a rate of ≥1% are presented in Table 1.

Opioid withdrawal symptoms (such as nausea, vomiting, diarrhoea, anxiety, and shivering) are possible in some patients after conversion from their previous opioid analgesic to DUROGESIC ® or if therapy is stopped suddenly (see Section 4.2, Posology and method of administration). There have been very rare reports of newborn infants experiencing neonatal ® withdrawal syndrome when mothers chronically used DUROGESIC during pregnancy (see Pregnancy and lactation). DRUG ABUSE AND ADDICTION ® …………..DUROGESIC patches are intended for transdermal use (to be applied on the skin) only. Do not use cut or damaged DUROGESIC® patches. Do not use a DUROGESIC® patch if the pouch seal is broken or the patch is cut, damaged, or changed in any way. DOSAGE AND ADMINISTRATION Special Precautions DUROGESIC® contains a high concentration of a potent opioid agonist, fentanyl. Opioid substances which includeing fentanyl, hydromorphone, 02 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 methadone, morphine, oxycodone, and oxymorphone have the highest potential for abuse and associated risk of fatal overdose due to respiratory depression. Fentanyl can be abused and is subject to criminal diversion. The ® high content of fentanyl in the patches (DUROGESIC ) may be a particular target for abuse and diversion. Durogesic® patches are intended for transdermal use (on intact skin) only. Do not use damaged ® or cut DUROGESIC patches. ® The DUROGESIC patch should not be used if the pouch seal is broken, or the patch is cut, damaged, or changed in any way. Each DUROGESIC® patch may be worn continuously for 72 hours. The next patch should be applied to a different skin site after removal of the previous transdermal system. If the patch falls off before 72 hours, dispose of it by folding in half and flushing down the toilet. A new patch may be applied to a different skin site. DUROGESIC is ONLY for use in patients who are already tolerant to opioid therapy of comparable potency. Use in non-opioid tolerant patients may lead to fatal respiratory depression. Overestimating the DUROGESIC® dose when converting patients from another opioid medication can result in fatal overdose with the first dose. Due to the mean elimination half-life of 17 approximately 20-27 hours of DUROGESIC®, patients who are thought to have had a serious adverse event, including overdose, will require monitoring and treatment for at least 24 hours. The concomitant use of DUROGESIC® with All potent cytochrome P450 3A4 inhibitors (such as ritonavir, ketoconazole, itraconazole, troleandomycin, clarithromycin, nelfinavir, nefazodone, and amiodarone, amprenavir, aprepitant, diltiazem ,erythromycin, fluconazole, fosamprenavir and verapamil) may result in an increase in fentanyl plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. Patients receiving Durogesic® and potent any CYP3A4 inhibitors should be carefully monitored for an extended period of time and dosage adjustments should be made if warranted. (See CLINICAL PHARMACOLOGY – Drug Interactions, WARNINGS, PRECAUTIONS and DOSAGE AND ADMINISTRATION for further information.) Respiratory depression is the chief hazard in elderly or debilitated patients, usually following large initial doses in non-tolerant patients, or when opioids are given in conjunction with other agents that depress respiration. DUROGESIC® should be used with caution in elderly, cachectic, or debilitated patients as they may have altered pharmacokinetics due to poor fat stores, muscle wasting, or altered clearance (see CLINICAL PHARMACOLOGY – Special Populations, Geriatric Use). General Principles ® DUROGESIC is indicated for management of persistent, moderate to severe chronic pain that: requires continuous, around-the-clock opioid administration for an extended period of time 01 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 cannot be managed by other means such as non-steroidal analgesics, opioid combination products, or immediate-release opioids. Durogesic is indicated for the management of chronic pain and intractable pain requiring opioid analgesia. Durogesic should only be used in patients who are already receiving opioid therapy, who have demonstrated opioid tolerance, ………………………….. DUROGESIC® should be applied immediately upon removal from the sealed package. Do not use if the pouch seal is broken. Do not alter the patch (e.g., cut) in any way prior to application and do not use cut or damaged patches. To remove the patch from the protective pouch, locate the pre-cut notch (indicated by an arrow on the patch label) along the edge of the seal. Fold the pouch at the notch, then carefully tear the pouch material. Further open the pouch along both sides, folding the pouch open like a book. The release liner for the matrix is slit. Fold the patch in the middle and remove each half of the liner separately. Avoid touching the adhesive side of the patch. Apply the patch to the skin by applying light pressure with the palm of the hand for about 30 seconds. Make certain that the edges of the patch are adhering properly. Then wash hands with clean water. The transdermal system should be pressed firmly in place with the palm of the hand for 30 seconds, making sure the contact is complete, especially around the edges. Do not use soap, alcohol, or other solvents to remove the gel because they may enhance the drug’s ability to penetrate the skin. Each DUROGESIC® may be worn continuously for 72 hours. The next patch should be applied to a different skin site after removal of the previous transdermal system. ……………………….. Dose Selection Doses must be individualized based upon the status of each patient and should be assessed at regular intervals after DUROGESIC® application. The patches are designed to deliver approximately 12, 25, 50, 75 and 100mcg/h fentanyl to the systemic circulation, which represent about 0.3, 0.6, 1.2, 1.8 and 2.4 mg per day, respectively. Reduced doses of Durogesic® are suggested for the elderly and other groups discussed in PRECAUTIONS. …………………….. Initial DUROGESIC® Dose Selection ® Overestimating the DUROGESIC dose when converting patients from another opioid medication can result in fatal overdose with the first dose. Due to the ® mean elimination half-life of approximately 20-27 17 hours of DUROGESIC , patients who are thought to have had a serious adverse event, including overdose, will require monitoring and treatment for at least 24 hours. ® There has been no systematic evaluation of DUROGESIC as an initial opioid analgesic in the management of chronic pain, since most patients in the clinical trials were converted to DUROGESIC® from other narcotics. The efficacy of DUROGESIC®12 mcg/h as an initiating dose has not been determined. In addition, patients who are not opioid-tolerant have 00 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 experienced hypoventilation and death during use of DUROGESIC. Therefore, DUROGESIC® should be used only in patients who are opioid-tolerant. ® To convert adult and pediatric patients from oral or parenteral opioids to DUROGESIC , use Table D (Equianalgesic potency conversion) and Table E (Recommended initial ® DUROGESIC dose based upon daily oral morphine dose): To convert adult patients from oral or parenteral opioids to DUROGESIC®, use Table C: Alternatively, for adult patients taking opioids or doses not listed in Table C, use the following methodology: 1. Calculate the previous 24-hour analgesic requirement. 2. Convert this amount to the equianalgesic oral morphine dose using Table D. 3. Table E displays the range of 24-hour oral morphine doses that are recommended for conversion to each DUROGESIC® dose. Use this table to find the calculated 24-hour morphine dose and the corresponding DUROGESIC® dose. Initiate DUROGESIC® treatment using the recommended dose and titrate patients upwards (no more frequently than every 3 days after the initial dose or than every 6 days thereafter) until a balance between analgesic efficacy and tolerability analgesic efficacy is attained. The recommended starting dose when converting from other opioids to DUROGESIC® is likely too low for 50% of patients. This starting dose is recommended to minimize the potential for overdosing patients with the first dose. For delivery rates in excess of 100 mcg/h, multiple systems may be used. ………………… The majority of patients are adequately maintained with DUROGESIC® administered every 72 hours. Some patients may not achieve adequate analgesia using this dosing interval and may require systems to be applied every 48 hours rather than every 72 hours. An increase in the DUROGESIC® dose should be evaluated before changing dosing intervals in order to maintain patients on a 72-hour regimen. Dosing intervals less than every 72 hours were not studied in children and adolescents and are not recommended Early in therapy, some patients may not achieve adequate analgesia during the third day using this dosing interval and may require DUROGESIC® patch to be applied at 48 hours rather than at 72 hours. Reducing the duration of system application by replacing the system before the 72 hours may result in increased serum concentrations of fentanyl. ……… Dose Titration ................ A 12mcg/h strength is available for dose titration. The dosage may subsequently be titrated upwards or downwards, if required, in increments of either 12 or 25 mcg/h to achieve the lowest appropriate dose of DUROGESIC® depending on response and supplementary analgesic requirements. ………………… Appropriate dosage increments should be based on the daily dose of supplementary opioids, using the ratio of 45 mg/24 hours of oral morphine to a 12.5 mcg/h increase in DUROGESIC® 03 J-C Health Care Ltd. Kibbutz Shefayim 60990, ISRAEL tel +972-9-959-1111 fax +972-9-958-3636 dose. DUROGESIC® -12 delivers 12.5 mcg/h of fentanyl. Safety and Handling Patches should be inspected prior to use. Patches that are cut, divided, or damaged in any way should not be used. Do not cut or damage DUROGESIC®. DURAGESIC® is supplied in sealed transdermal systems which pose little risk of exposure to health care workers. ® Do not use a DUROGESIC patch if the pouch seal is broken or the patch is cut, damaged, or changed in any way. שינויים בעלון לצרכן: אין להשתמש בתרופה מבלי להיוועץ ברופא לפני התחלת הטיפול ( )Xאם הנך מעל גיל 00 איך תשפיע התרופה על חיי היום יום שלך ? אין לשתות יינות או משקאות חריפים בתקופת הטיפול עם התרופה מאחר והשילוב ביניהם יכול לגרום לישנוניות. אזהרות : במידה והמדבקה נפלה מאליה יש לזרוק אותה להדביק מדבקה חדשה מיד כאשר הבחנת/ה בכך .את המדבקה החדשה יש להדביק באיזור אחר על העור. יידע את הרופא במידה ואתה או מישהו אחר במשפחתך פיתח בעבר תלות או שימוש לרעה באכוהול,תרופות מרשם או סמים. תגובות בין תרופתיות אם הינך נוטל/ת תרופה נוספת ,כולל תרופות הנמכרות ללא מרשם ותוספי תזונה או אם גמרת זה עתה הטיפול בתרופה אחרת עליך לדווח לרופא המטפל כדי למנוע סיכונים או אי-יעילות הנובעים מתגובות בין תרופתיות)X( . במיוחד ,לגבי תרופות מהקבוצות הבאות: () Xתרופות מסויימות לטיפול בזיהומים פטרייתיים (כגון קטוקונזול ,פלוקונזול ואינטרקונזול) (Xתרופות מסוימות לטיפול באיידס (כגון תרופות המכילות ריטונוויר ,אמפנוויר ,פוסאמפנוויר ונלפינוויר).
