    <IndicationAndUsage>Buprenorphine transdermal system is indicated for the management of severe and persistent pain that requires an opioid analgesic and that cannot be adequately treated with alternative options, including immediate release opioids. Limitations of Use: 1 Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration and persist over the course of therapy [see Warnings and Precautions ( 5.1)] , reserve opioid analgesics, including buprenorphine transdermal system, for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. , 2 Buprenorphine transdermal system is not indicated as an as-needed (prn) analgesic.</IndicationAndUsage>
    <Description>Buprenorphine transdermal system is a transdermal system providing systemic delivery of buprenorphine, a mu opioid partial agonist analgesic, continuously for 7 days. The chemical name of buprenorphine is (5 R,6 R,7 R,9 R,13 S,14 S)-17-Cyclopropylmethyl-7-[( S)-3,3-dimethyl-2-hydroxybutan-2-yl]-6-methoxy-4,5-epoxy-6,14-ethanomorphinan-3-ol. The structural formula is:. The molecular weight of buprenorphine is 467.64; the empirical formula is C 29H 41NO 4. Buprenorphine occurs as a white or almost white crystalline powder and is very slightly soluble in water, freely soluble in acetone, soluble in methanol, and slightly soluble in cyclohexane. It dissolves in dilute solutions of acids. The pKa is 8.35 and the melting point is about 217°C. System Components and Structure. Five different strengths of buprenorphine transdermal system are available: 5, 7.5, 10, 15, and 20 mcg/hour (Table 6). The proportion of buprenorphine mixed in the adhesive matrix is the same in each of the five strengths. The amount of buprenorphine released from each system per hour is proportional to the active surface area of the system. The skin is the limiting barrier to diffusion from the system into the bloodstream. Table 6: Buprenorphine Transdermal System Product Specifications. Buprenorphine transdermal system is a rectangular or square, tan-colored system consisting of a protective liner and functional layers. Proceeding from the outer surface toward the surface adhering to the skin, the layers are (1) a beige-colored web backing layer; (2) an adhesive rim without buprenorphine; (3) a separating layer over the buprenorphine-containing adhesive matrix; (4) the buprenorphine-containing adhesive matrix; and (5) a peel-off release liner. Before use, the release liner covering the adhesive layer is removed and discarded. Figure 1: Cross-Section Diagram of Buprenorphine Transdermal System (not to scale). The active ingredient in buprenorphine transdermal system is buprenorphine. The inactive ingredients in each system are: levulinic acid, oleyl oleate, povidone, and polyacrylate cross-linked with aluminum.</Description>

    <IndicationAndUsage>Buprenorphine transdermal system is indicated for the management of severe and persistent pain that requires an opioid analgesic and that cannot be adequately treated with alternative options, including immediate release opioids. Limitations of Use: 1 Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration and persist over the course of therapy [see Warnings and Precautions ( 5.1)] , reserve opioid analgesics, including buprenorphine transdermal system, for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. , 2 Buprenorphine transdermal system is not indicated as an as-needed (prn) analgesic.</IndicationAndUsage>
    <Description>Buprenorphine transdermal system is a transdermal system providing systemic delivery of buprenorphine, a mu opioid partial agonist analgesic, continuously for 7 days. The chemical name of buprenorphine is (5 R,6 R,7 R,9 R,13 S,14 S)-17-Cyclopropylmethyl-7-[( S)-3,3-dimethyl-2-hydroxybutan-2-yl]-6-methoxy-4,5-epoxy-6,14-ethanomorphinan-3-ol. The structural formula is:. The molecular weight of buprenorphine is 467.64; the empirical formula is C 29H 41NO 4. Buprenorphine occurs as a white or almost white crystalline powder and is very slightly soluble in water, freely soluble in acetone, soluble in methanol, and slightly soluble in cyclohexane. It dissolves in dilute solutions of acids. The pKa is 8.35 and the melting point is about 217°C. System Components and Structure. Five different strengths of buprenorphine transdermal system are available: 5, 7.5, 10, 15, and 20 mcg/hour (Table 6). The proportion of buprenorphine mixed in the adhesive matrix is the same in each of the five strengths. The amount of buprenorphine released from each system per hour is proportional to the active surface area of the system. The skin is the limiting barrier to diffusion from the system into the bloodstream. Table 6: Buprenorphine Transdermal System Product Specifications. Buprenorphine transdermal system is a rectangular or square, tan-colored system consisting of a protective liner and functional layers. Proceeding from the outer surface toward the surface adhering to the skin, the layers are (1) a beige-colored web backing layer; (2) an adhesive rim without buprenorphine; (3) a separating layer over the buprenorphine-containing adhesive matrix; (4) the buprenorphine-containing adhesive matrix; and (5) a peel-off release liner. Before use, the release liner covering the adhesive layer is removed and discarded. Figure 1: Cross-Section Diagram of Buprenorphine Transdermal System (not to scale). The active ingredient in buprenorphine transdermal system is buprenorphine. The inactive ingredients in each system are: levulinic acid, oleyl oleate, povidone, and polyacrylate cross-linked with aluminum.</Description>

    <IndicationAndUsage>Buprenorphine transdermal system is indicated for the management of severe and persistent pain that requires an extended treatment period with a daily opioid analgesic and for which alternative treatment options are inadequate. Limitations of Use: 1 Because of the risks of addiction, abuse and misuse with opioids, which can occur at any dosage or duration, and because of the greater risk of overdose and death with extended-release/long-acting opioid formulations [see Warnings and Precautions (5.1)], reserve buprenorphine transdermal system for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. , 2 Buprenorphine transdermal system is not indicated as an as-needed (prn) analgesic .</IndicationAndUsage>
    <Description>Buprenorphine transdermal system is a transdermal system providing systemic delivery of buprenorphine, a mu opioid partial agonist analgesic, continuously for 7 days. The chemical name of buprenorphine is 6,14-ethenomorphinan-7-methanol, 17-(cyclopropylmethyl)- α-(1,1-dimethylethyl)-4, 5-epoxy-18, 19-dihydro-3-hydroxy-6-methoxy-α-methyl-, [5α, 7α, (S)]. The structural formula is. The molecular weight of buprenorphine is 467.6; the empirical formula is C29H41NO4. Buprenorphine occurs as a white or almost white powder and is very slightly soluble in water, freely soluble in acetone, soluble in methanol and ether, and slightly soluble in cyclohexane. The pKa is 8.5 and the melting point is about 217°C. System Components and StructureFive different strengths of buprenorphine transdermal system are available: 5 mcg/hour, 7.5 mcg/hour, 10 mcg/hour, 15 mcg/hour, and 20 mcg/hour (Table 6). The proportion of buprenorphine mixed in the adhesive matrix is the same in each of the five strengths. The amount of buprenorphine released from each system per hour is proportional to the active surface area of the system. The skin is the limiting barrier to diffusion from the system into the bloodstream. Table 6: Buprenorphine Transdermal System Product Specifications. Buprenorphine transdermal system is a rectangular or square, beige-colored system consisting of a protective liner and functional layers. Proceeding from the outer surface toward the surface adhering to the skin, the layers are (1) a beige-colored web backing layer; (2) an adhesive rim without buprenorphine; (3) a separating layer over the buprenorphine-containing adhesive matrix; (4) the buprenorphine-containing adhesive matrix; and (5) a peel-off release liner. Before use, the release liner covering the adhesive layer is removed and discarded. Figure 1: Cross-Section Diagram of Buprenorphine Transdermal System (not to scale). The active ingredient in buprenorphine transdermal system is buprenorphine. The inactive ingredients in each system are: cross-linked polyacrylate, levulinic acid, oleyl oleate, and kollidon 90F.</Description>

    <IndicationAndUsage>Buprenorphine transdermal system is indicated for the management of severe and persistent pain that requires an extended treatment period with a daily opioid analgesic and for which alternative treatment options are inadequate. Limitations of Use: 1 Because of the risks of addiction, abuse and misuse with opioids, which can occur at any dosage or duration, and because of the greater risk of overdose and death with extended-release/long-acting opioid formulations [see Warnings and Precautions (5.1)], reserve buprenorphine transdermal system for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. , 2 Buprenorphine transdermal system is not indicated as an as-needed (prn) analgesic .</IndicationAndUsage>
    <Description>Buprenorphine transdermal system is a transdermal system providing systemic delivery of buprenorphine, a mu opioid partial agonist analgesic, continuously for 7 days. The chemical name of buprenorphine is 6,14-ethenomorphinan-7-methanol, 17-(cyclopropylmethyl)- α-(1,1-dimethylethyl)-4, 5-epoxy-18, 19-dihydro-3-hydroxy-6-methoxy-α-methyl-, [5α, 7α, (S)]. The structural formula is. The molecular weight of buprenorphine is 467.6; the empirical formula is C29H41NO4. Buprenorphine occurs as a white or almost white powder and is very slightly soluble in water, freely soluble in acetone, soluble in methanol and ether, and slightly soluble in cyclohexane. The pKa is 8.5 and the melting point is about 217°C. System Components and StructureFive different strengths of buprenorphine transdermal system are available: 5 mcg/hour, 7.5 mcg/hour, 10 mcg/hour, 15 mcg/hour, and 20 mcg/hour (Table 6). The proportion of buprenorphine mixed in the adhesive matrix is the same in each of the five strengths. The amount of buprenorphine released from each system per hour is proportional to the active surface area of the system. The skin is the limiting barrier to diffusion from the system into the bloodstream. Table 6: Buprenorphine Transdermal System Product Specifications. Buprenorphine transdermal system is a rectangular or square, beige-colored system consisting of a protective liner and functional layers. Proceeding from the outer surface toward the surface adhering to the skin, the layers are (1) a beige-colored web backing layer; (2) an adhesive rim without buprenorphine; (3) a separating layer over the buprenorphine-containing adhesive matrix; (4) the buprenorphine-containing adhesive matrix; and (5) a peel-off release liner. Before use, the release liner covering the adhesive layer is removed and discarded. Figure 1: Cross-Section Diagram of Buprenorphine Transdermal System (not to scale). The active ingredient in buprenorphine transdermal system is buprenorphine. The inactive ingredients in each system are: cross-linked polyacrylate, levulinic acid, oleyl oleate, and kollidon 90F.</Description>

    <IndicationAndUsage>Buprenorphine transdermal system is indicated for the management of severe and persistent pain that requires an opioid analgesic and that cannot be adequately treated with alternative options, including immediate release opioids. Limitations of Use: 1 Because of the risks of addiction, abuse, misuse, overdose, and death, which can occur at any dosage or duration and persist over the course of therapy [see Warnings and Precautions ( 5.1)] , reserve opioid analgesics, including buprenorphine transdermal system, for use in patients for whom alternative treatment options are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain. , 2 Buprenorphine transdermal system is not indicated as an as-needed (prn) analgesic.</IndicationAndUsage>
    <Description>Buprenorphine transdermal system is a transdermal system providing systemic delivery of buprenorphine, a mu opioid partial agonist analgesic, continuously for 7 days. The chemical name of buprenorphine is (5 R,6 R,7 R,9 R,13 S,14 S)-17-Cyclopropylmethyl-7-[( S)-3,3-dimethyl-2-hydroxybutan-2-yl]-6-methoxy-4,5-epoxy-6,14-ethanomorphinan-3-ol. The structural formula is:. The molecular weight of buprenorphine is 467.64; the empirical formula is C 29H 41NO 4. Buprenorphine occurs as a white or almost white crystalline powder and is very slightly soluble in water, freely soluble in acetone, soluble in methanol, and slightly soluble in cyclohexane. It dissolves in dilute solutions of acids. The pKa is 8.35 and the melting point is about 217°C. System Components and Structure. Five different strengths of buprenorphine transdermal system are available: 5, 7.5, 10, 15, and 20 mcg/hour (Table 6). The proportion of buprenorphine mixed in the adhesive matrix is the same in each of the five strengths. The amount of buprenorphine released from each system per hour is proportional to the active surface area of the system. The skin is the limiting barrier to diffusion from the system into the bloodstream. Table 6: Buprenorphine Transdermal System Product Specifications. Buprenorphine transdermal system is a rectangular or square, tan-colored system consisting of a protective liner and functional layers. Proceeding from the outer surface toward the surface adhering to the skin, the layers are (1) a beige-colored web backing layer; (2) an adhesive rim without buprenorphine; (3) a separating layer over the buprenorphine-containing adhesive matrix; (4) the buprenorphine-containing adhesive matrix; and (5) a peel-off release liner. Before use, the release liner covering the adhesive layer is removed and discarded. Figure 1: Cross-Section Diagram of Buprenorphine Transdermal System (not to scale). The active ingredient in buprenorphine transdermal system is buprenorphine. The inactive ingredients in each system are: levulinic acid, oleyl oleate, povidone, and polyacrylate cross-linked with aluminum.</Description>
