To develop a model to predict buprenorphine plasma concentrations during transition from transdermal to buccal administration.
In patch-based transdermal drug delivery, adhesiveness is critical for safe and effective treatment, especially in Parkinson's disease (PD) where excessive sweating is common. This study compared the adhesiveness of two transdermal patch formulations of rotigotine (improved room temperature-stable [PR2.3.1/Treatment A] and intermediate cold storage product [PR2.1.1/Treatment B]), using the largest patch size (40 cm).
The cutaneous fentanyl patch is widely used to treat continuous pain in patients with cancer. Its use is hampered by a high inter- and intrapatient pharmacokinetic variability. Factors that influence this pharmacokinetic variability are largely unclear. The aim of these studies was to test if common patient variables, i) the use of the moderate CYP3A4 inhibitor aprepitant and ii) the localization of the fentanyl patch (upper arm versus thorax) influence systemic exposure to fentanyl in patients with cancer ...
A cluster-analytic profiling of heroin-dependent patients based on level, clinical adequacy, and patient-desired adjustment of buprenorphine dosage during buprenorphine-naloxone maintenance treatment in sixteen Spanish centers.
Buprenorphine dosage is a crucial factor influencing outcomes of buprenorphine treatment for heroin use disorders. Therefore, the aim of the present study is to identify naturally occurring profiles of heroin-dependent patients regarding individualized management of buprenorphine dosage in clinical practice of buprenorphine-naloxone maintenance treatment.
Pharmacokinetic studies using deconvolution methods and non-compartmental analysis to model clinical absorption of drugs are not well represented in the literature. The purpose of this research was (1) to define the system of equations for description of rotigotine (a dopamine receptor agonist delivered via a transdermal patch) absorption based on a pharmacokinetic model and (2) to describe the kinetics of rotigotine disposition after single and multiple dosing.
Buprenorphine maintenance therapy patients frequently have severe postoperative pain due to buprenorphine-induced hyperalgesia and provider use of opioids with limited efficacy in the presence of buprenorphine. The authors report good-to-excellent pain management in 4 obstetric patients using nonopioid analgesics, regional anesthesia, continuation of buprenorphine, and use of opioids with high μ receptor affinity.
While there has been a dramatic increase in prescribing of buprenorphine for the treatment of opioid use disorder in the US, little is known about prescribers' attitudes and practices regarding buprenorphine diversion and how they relate to prescriber characteristics.
DATA 2000 enabled physicians with approved training to be waivered to prescribe buprenorphine for the treatment of opioid use disorders (OUD) for a limited number of patients. A rule change in 2016 increased the patient limit for certain buprenorphine waivered physicians from 100 to 275. This study examines the prescribing patterns of buprenorphine prescribers by waiver limit status (30- or 100-patient limit).
Transdermal delivery of drugs is comparatively new in feline patients. However, transdermal formulations can be a desirable option for treating feline patients that are not willing participants to medication administration. However, achieving drug penetration across the skin is not always easy, and there are a wide variety of variables that can further affect penetration. This, coupled with a lack of studies, make transdermal administration an unknown with regards to efficacy and safety for many drugs. This...
Opioid use disorders are a major medical and public health concern. Buprenorphine is approved for the treatment of opioid use disorders; however, a shortage of physicians prescribing buprenorphine is a significant barrier to treatment access. The aims of this study were to evaluate opinions of internal medicine attending and resident physicians about buprenorphine and assess interest in becoming waivered to prescribe.
Various kinds of functional cosmetics are on the market, although there are a variety of opinions concerning the actual effect. Transdermal microneedle patch has been introduced as a newly developed device for drug delivery through the skin.
Office-based buprenorphine maintenance has been legalized and promoted as a treatment approach that not only expands access to care, but also reduces the stigma of addiction treatment by placing it in a mainstream clinical setting. At the same time, there are differences in buprenorphine treatment utilization by race, ethnicity, and socioeconomic status.
Transfer from methadone to buprenorphine is problematic for many opioid-dependent patients, with limited documented evidence or practical clinical guidance, particularly for the range of methadone doses routinely prescribed for most patients (>50 mg). This study aimed to implement and evaluate recent national Australian guidelines for transferring patients from methadone to buprenorphine.
The objective of this study was to investigate the effect of dispersion states of azone in gels on the transdermal permeation of levamisole hydrochloride (LH). LH hydro-alcoholic gels containing azone of different dispersion states were prepared by varying the contents of azone and Tween80, and the in vitro transdermal permeation of LH across excised rat skin was evaluated. Depending on the content of azone, mixed solvents and solubilizer used, azone presented as dissolved molecules, solubilized in micelles...
Melanin is capable of transforming 99.9% of the absorbed sunlight energy into heat, reducing the risk of skin cancer. We here develop a melanin-mediated cancer immunotherapy strategy through a transdermal microneedle patch. B16F10 whole tumor lysate containing melanin is loaded into polymeric microneedles that allow sustained release of the lysate upon insertion into the skin. In combination with the near-infrared light irradiation, melanin in the patch mediates the generation of heat, which further promote...
Starting with approval for clinical use in the treatment of opioid dependence in October 2002 by the Food and Drug Administration (FDA), buprenorphine has become an integral treatment option and in recent years, in chronic pain management. Buprenorphine possesses a unique pharmacodynamic and pharmacokinetic profile that can potentially make perioperative analgesia challenging.
Transdermal compositions for hormone replacement are comprised of exogenous hormones that are biochemically similar to those produced endogenously by the ovaries or elsewhere in the body. In this work, estradiol, estriol, and testosterone were loaded in transdermal vehicles, prepared using one of three selected penetration enhancer mixtures: Vehicle 1 (olive oil and oleic acid), Vehicle 2 (isopropyl palmitate and lecithin), and Vehicle 3 (isopropyl myristate and lecithin). The influence of penetration enhan...
The principal study objective was to investigate the pharmacokinetic characteristics and determine the absolute bioavailability and tolerability of a new sublingual (SL) buprenorphine wafer.
OBJECTIVE To determine pharmacokinetics and sedative effects of buprenorphine after IV and oral transmucosal (OTM) administration in guinea pigs. ANIMALS 14 male guinea pigs (6 adults for preliminary experiment; eight 8 to 11-week-old animals for primary study). PROCEDURES A preliminary experiment was conducted to determine an appropriate buprenorphine dose. In the primary study, buprenorphine (0.2 mg/kg) was administered IV or OTM, and blood samples were obtained. The pH of the oral cavity was measured bef...
A matrix transdermal patch of bisoprolol fumarate was formulated with different concentrations of Eudragit RS 100 and Methocel E5 with PEG 400 as plasticizer by solvent evaporation technique. Tween 80 was added to the optimized patch to evaluate the effect of permeation enhancer at different concentration through the excised rabbit's skin. The patches were analyzed for weight variation, drug content, swelling index, erosion studies, moisture content, moisture uptake, water vapor transmission rate (WVTR) and...
Rates of non-medical use of opioids, and opioid use disorders (OUD) have been rising throughout North America. Methadone and buprenorphine/naloxone are the recommended first-line treatment options for OUD in Canada. Most studies to date have been conducted among heroin users, in controlled settings, and using similar strict dosing schedules (i.e., daily witnessed ingestion) despite buprenorphine/naloxone's superior safety profile, which allows a more flexible take-home dosing schedule. This study was design...
Wearable transdermal delivery systems have recently received tremendous attention due to their noninvasive, convenient, and prolonged administration of pharmacological agents. Here, the material prospects, fabrication processes, and drug-release mechanisms of these types of therapeutic delivery systems are critically reviewed. The latest progress in the development of multifunctional wearable devices capable of closed-loop sensation and drug delivery is also discussed. This survey reveals that wearable tran...
To estimate whether opioid substitution treatment (OST) with buprenorphine or methadone is associated with a greater reduction in the risk of all-cause mortality (ACM) and opioid drug-related poisoning (DRP) mortality.
OBJECTIVE To determine the pharmacokinetics and sedative effects of 2 doses of a concentrated buprenorphine formulation after SC administration to red-tailed hawks (Buteo jamaicensis). ANIMALS 6 adult red-tailed hawks. PROCEDURES Concentrated buprenorphine (0.3 mg/kg, SC) was administered to all birds. Blood samples were collected at 10 time points over 24 hours after drug administration to determine plasma buprenorphine concentrations. After a 4-week washout period, the same birds received the same formula...
