Transdermal buprenorphine patches applied in a 4-day regimen versus a 3-day regimen: a single-site, Phase III, randomized, open-label, crossover comparison.
In 2001, a transdermal matrix patch formulation of buprenorphine was approved for the treatment of moderate to severe cancer pain and severe pain that is unresponsive to nonopioid analgesics. The primary recommendation contained in the prescribing information was that transdermal patches be worn for a 3-day period before application of a new patch.. This study was conducted to evaluate the potential for extending the time the buprenorphine patch is worn from 3 to 4 days.. This single-center, randomized, open-label, crossover Phase III study compared the efficacy and tolerability of the buprenorphine transdermal patch applied for different durations, with patch changes every 3 days versus every 4 days (12 days each), in patients with chronic moderate or severe pain of malignant or nonmalignant origin. Study participants were aged >18 years, had already responded to at least 4 weeks of transdermal buprenorphine, and had achieved steady-state conditions for at least 2 weeks before enrollment. The primary end point was patients' rating of the quality of treatment (analgesic efficacy and tolerability, rated on a 5-point scale: very good, good, satisfactory, poor, and inadequate) at the completion of each treatment regimen. Also recorded were physicians' ratings of the quality of treatment; pain intensity, rated on an 11-point numerical rating scale (from 0 = no pain to 10 = worst pain imaginable) and on the McGill Pain Questionnaire (MPQ) (maximum pain = 3.0); health status, assessed using the 36-item Short Form Health Survey (SF-36), expressed as a percentage of the best health condition (100%); and pain relief (5-point scale: complete, good, satisfactory, slight, and none). Local skin tolerability was evaluated for objective and subjective dermatologic symptoms at the patch application sites. Patients recorded daily pain intensities at specified times of day and night, pain relief (5-point verbal rating scale), and sleep duration ( Topics: Administration, Cutaneous; Aged; Analgesics, Opioid; Buprenorphine; Cross-Over Studies; Drug Administration Schedule; Erythema; Female; Humans; Male; Middle Aged; Pain; Pain Measurement; Patient Satisfaction; Quality of Health Care; Severity of Illness Index; Treatment Outcome | 2007 |
A comparison of the skin irritation potential of transdermal fentanyl versus transdermal buprenorphine in middle-aged to elderly healthy volunteers.
Establishing local tolerability of transdermal opioid systems is important as more systems become available for use in a range of indications. We compared the skin irritation potential of a single application of transdermal fentanyl (Durogesic D-trans; DDTDF) and transdermal buprenorphine (Transtec; TDB) patches in healthy volunteers.. 46 healthy males and females (mean age [range]: 59.6 [50-69] years) with healthy skin received a single dose of both the DDTDF 25 mug/h patch and the TDB 35 mug/h patch in a randomised order under naltrexone cover. The incidence and severity of erythema was assessed at various timepoints after patch removal.. There was a non-significant trend towards a higher incidence of erythema 60 min after patch removal with TDB compared with DDTDF. The severity of erythema at 60 min and the incidence of erythema at 72 h after patch removal were significantly higher with TDB than with DDTDF (p = 0.01 and 22% versus 4.9%, p = 0.04, respectively). In general, the results from the chromametric assessment of treated skin were in agreement. The incidence of topical adverse events (AEs) was lower with DDTDF than with TDB (one versus six events) and subjects preferred the DDTDF patch and felt it was less noticeable on the skin. The DDTDF patch was considered less painful to remove, and, consistent with that, the TDB patch was judged to have better adhesion. Twenty-one subjects reported systemic AEs with DDTDF plus naltrexone and 22 with TDB plus naltrexone, most of which were considered treatment-related, 34 and 60 AEs, respectively.. Local tolerability of transdermal opioid systems should be considered when making a therapeutic choice. Even after a single application in healthy volunteers, differences in local tolerability, assessed both clinically and by chromametry, and patch comfort were shown between DDTDF and TDB, in favour of DDTDF.
