Int J Pharm 2024; 659:124295. [PMID: 38823469 DOI: 10.1016/j.ijpharm.2024.124295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 05/13/2024] [Accepted: 05/29/2024] [Indexed: 06/03/2024]
Abstract
Opioids are powerful analgesics; however, their significant systemic adverse effects and the need for frequent administration restrict their use. Nalbuphine (NA) is a κ-agonist narcotic with limited adverse effects, but needs to be frequently administrated due to its short elimination half-life. Whereas sebacoyl dinalbuphine ester (SDE) is a NA prodrug, which can effectively prolong the analgesic effect, but lacks immediate pain relief. Therefore, in this study, a rapid and sustained local delivery formulation to introduce NA and SDE directly into surgical sites was developed. An amphiphilic nanostructured lipid carrier (NLC) poloxamer 407 (P407) gel (NLC-Gel) was developed to permit concurrent delivery of hydrophobic SDE from the NLC core and hydrophilic NA from P407, offering a dual rapid and prolonged analgesic effect. Benefiting from the thermal-sensitive characteristic of P407, the formulation can be injected in liquid phase and instantly transit into gel at wound site. NLC-Gel properties, including particle size, drug release, rheology, and stability, were assessed. In vivo evaluation using a rat spinal surgery model highlighted the effect of the formulation through pain behavior test and hematology analysis. NLC-Gels demonstrated an analgesic effect comparable with that of commercial intramuscular injected SDE formulation (IM SDE), with only 15 % of the drug dosage. The inclusion of supplemental NA in the exterior gel (PA12-Gel + NA) provided rapid drug onset owing to swift NA dispersion, addressing acute pain within hours along with prolonged analgesic effects. Our findings suggest that this amphiphilic formulation significantly enhanced postoperative pain management in terms of safety and efficacy.

Efficacy and safety of an extended-release sebacoyl dinalbuphine ester for laparoscopic cholecystectomy: A randomized controlled trial. Medicine (Baltimore) 2023; 102:e34423. [PMID: 37543779 PMCID: PMC10403043 DOI: 10.1097/md.0000000000034423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 08/07/2023] Open
Abstract
BACKGROUND A long-acting κreceptor agonist parenteral analgesic may theoretically improve acute pain and reduce incidence of chronic postsurgical pain (CPSP) after laparoscopic cholecystectomy with minimal drug-related side effects of the traditional μreceptor opioids. METHODS Eighty adult patients undergoing elective laparoscopic cholecystectomy were randomly assigned to receive single intramuscular injection of an extended-release sebacoyl dinalbuphine ester (SDE, Naldebain 150 mg; n = 40) or placebo (n = 40) after anesthesia induction. Standard multimodal analgesia (MMA) was administered for postoperative pain control. The primary endpoint was pain intensity within 7 days after surgery. The secondary endpoints were incidence CPSP at 3 months and adverse reactions up to 7 days after surgery. RESULTS The highest visual analogue scale (VAS) and area under the curve of VAS 0 to 48 hours after operation were not different between the two groups and a similar proportion of patients requested rescue parenteral analgesics. Average pain intensities were also not different at 72 hours and 7 days after surgery. Incidence of CPSP was 22.5% and 13.1% in patients who received placebo and SDE treatment, respectively (P = .379). Significantly higher incidence of drug-related adverse events, including dizziness, nausea and injection site reactions, were recorded in the SDE group. CONCLUSION A single dose of extended-release analgesic SDE given intraoperatively did not provide sufficient add-on effect for acute and chronic pain management after laparoscopic cholecystectomies in patients who received standard postoperative MMA. Intramuscular injection of 150 mg SDE in patients with average body mass causes adverse events that could have been overlooked. More clinical studies are warranted to determine the target populations who may benefit from SDE injections for improvement of acute and chronic postsurgical pain management.

Abstract
Long-acting injectable (LAIs) delivery systems sustain the drug therapeutic action in the body, resulting in reduced dosage regimen, toxicity, and improved patient compliance. Lipid-based depots are biocompatible, provide extended drug release, and improve drug stability, making them suitable for systemic and localized treatment of various chronic ailments, including psychosis, diabetes, hormonal disorders, arthritis, ocular diseases, and cancer. These depots include oil solutions, suspensions, oleogels, liquid crystalline systems, liposomes, solid lipid nanoparticles, nanostructured lipid carriers, phospholipid phase separation gel, vesicular phospholipid gel etc. This review summarizes recent advancements in lipid-based LAIs for delivering small and macromolecules, and their potential in managing chronic diseases. It also provides an overview of the lipid depots available in market or clinical phase, as well as patents for lipid-based LAIs. Furthermore, this review critically discusses the current scenario of using in vitro release methods to establish IVIVC and highlights the challenges involved in developing lipid-based LAIs.

Efficacy and Safety of Parenteral Injection of an Extended Release κ-receptor Opioid Sebacoyl Dinalbuphine Ester for Acute and Chronic Pain After Laparoscopic Bariatric Surgery: a Randomized, Placebo-Controlled, Double-Blind Trial. Obes Surg 2023; 33:1192-1201. [PMID: 36787017 DOI: 10.1007/s11695-023-06502-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Revised: 01/29/2023] [Accepted: 02/07/2023] [Indexed: 02/15/2023]
Abstract
PURPOSE μ-receptor opioids are associated with unwanted gastrointestinal side effects and respiratory depression. A long-acting non-μ-receptor parenteral opioid is not currently available for management of acute and chronic postsurgical pain (CPSP). This double-blind clinical trial tested an extended-release κ-receptor agonist, sebacoyl dinalbuphine ester (SDE, Naldebain®) for management of surgical pain after laparoscopic bariatric surgery. MATERIALS AND METHODS Patients were randomly assigned to receive a single intramuscular injection of SDE (150 mg, n = 30) or vehicle solution (n = 30) at > 12 h before surgery. All patients received standard perioperative multimodal analgesia (MMA). The primary endpoint was the pain intensity in the beginning 7 days after operation. The secondary endpoints were adverse reactions up to 7 days and incidence of CPSP at 3 months after surgery. RESULTS Compared with placebos, the area under curves of visual analog scale (VAS) for 0-48 h after operation were significantly reduced in SDE group (143.3 ± 65.4 and 105.9 ± 36.3, P = 0.025). There were significantly fewer patients in the SDE group who had moderate-to-severe pain (VAS ≥ 4) (16.7% vs 50%; P = 0.012) at postoperative 48 h. Pain intensities were similar between the two groups at 72 h and 7 days postoperatively. The incidence of CPSP at 3 months was not different. SDE did not increase drug-related systemic adverse events. CONCLUSION In addition to the standard perioperative MMA, a single-dose injection of long-acting κ-receptor agonist SDE provides significantly better pain management for 48 h following laparoscopic bariatric surgery. A long-acting κ-receptor agonist opioid could improve in-hospital pain management and potentiate early discharge after operation without increasing drug-related systemic complications.

Repurposing of parenterally administered active substances used to treat pain both systemically and locally. Drug Discov Today 2022; 27:103321.

Abstract
Pain is a constant in our lives. The efficacy of drug therapy administered by the parenteral route is often limited either by the physicochemical characteristics of the drug itself or its adsorption-distribution-metabolism-excretion (ADME) mechanisms. One promising alternative is the design of innovative drug delivery systems that can improve the pharmacokinetics |(PK) and/or reduce the toxicity of traditionally used drugs. In this review, we discuss several products that have been approved by the main regulatory agencies (i.e., nano- and microsystems, implants, and oil-based solutions), highlighting the newest technologies that govern both locally and systemically the delivery of drugs. Finally, we also discuss the risk assessment of the scale-up process required, given the impact that this approach could have on drug manufacturing. Teaser: The management of pain by way of the parenteral route can be improved using complex drug delivery systems (e.g., micro- and nanosystems) which require high-level assessment and shorten the regulatory pathway.

Abstract
Previously compound 12 showed great anti-trypanosome activity without toxicity in an in vivo study. In the current study, a sensitive and rapid high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method was developed and validated to investigate its pharmacokinetics in mouse plasma. A protein precipitation method was applied to extract the compound, and it was then separated using a Kinetex C18 column with mobile phase consisting of acetonitrile-0.1% formic acid water (50:50, v/v) at a flow rate of 300 μl/min. The analytes were detected with the multiple reaction monitoring in negative electrospray ionization source for quantitative response of the compounds. Compound 12 was detected at m/z 477.0 → 367.2, while the internal standard compound 14 was detected at m/z 499.2 → 268.2. Inter- and intra-day precision was <5.22 and 2.79% respectively, while the accuracy range was within ±9.65%. The method was successfully applied to evaluate the pharmacokinetics of compound 12 in mouse plasma with two formulations (20% Cremophor EL or sesame oil) and drug administration routes (oral and intraperitoneal injection). We observed a better drug serum concentration with the Cremophor formulation, and the two different drug administration routes did not show significant differences from the drug distribution.

Abstract
Sebacoyl dinalbuphine ester (SDE) is a nalbuphine (NA) prodrug capable of biotransformation in vivo and prolong the duration of NA, maximize its effect in pain and pruritus management. However, the large molecular weight, low skin penetration, and stability concerns of SDE make it difficult to be used in local skin delivery. Nanostructured lipid carrier (NLC) is a lipid-based nanoparticulate system that has the potential for formulating SDE in order to promote drug delivery through the skin. The aim of this study was to develop SDE-loaded NLC formulations (SDE-NLC) with good stability, sustained release characteristics, and sufficient antipruritic effect. SDE was successfully encapsulated into NLC and the formulation increased the stability of SDE, enhanced skin penetration through hair follicles, and sustained SDE release during pruritus management. We also demonstrated that topical application of SDE-NLCs significantly reduced the number of scratches in pruritus-induced mice. Both NA and SDE were found in the skin strata, but only NA was detectable in the plasma, indicating rapid conversion of SDE into NA. All results demonstrated that SDE-NLC formulation protected SDE from degradation in vitro, while the released prodrug was converted into NA in vivo and extended antipruritic effect. The formulation has the potential of improving the life quality of patients with chronic pruritus.

Abstract
INTRODUCTION Formulation of nanocrystals is one of the most important drug delivery systems for poorly soluble drug molecules. Nanocrystals are produced by techniques like precipitation, media milling, high-pressure homogenization, and so on. In order to achieve sustained release and higher absorption of nanosuspensions, intramuscularly administered nanosuspensions have been developed. As well, intramuscularly administered nanosuspensions have been implemented in order to improve the bioavailability of drug nanocrystals which have both a low oral bioavailability and cannot be administered by intravenous injection routes. AREAS COVERED This review summarizes studies that have focused on the production, classification, in vitro release and in vivo pharmacokinetics of intramuscularly administered nanosuspensions. In order to avoid common drawbacks of intramuscularly administered nanosuspensions, such as tissue residues and some local tissue damage, nanosuspensions with a reduced administration volume of high drug loading and extended therapeutic effects are developed. EXPERT OPINION Intramuscularly administered nano/micro crystal suspensions have been developed for the treatment of various diseases such as schizophrenia, hormone disordered diseases, HIV and more. Additionally, intramuscularly administered nanosuspensions are also a good route for the development of traditional chinese medicines which have lower oral bioavailability and are not suitable for intravenous injection.

Comparing efficacy and safety between Naldebain ® and intravenous patient-controlled analgesia with fentanyl for pain management post-laparotomy: study protocol for a randomized controlled, non-inferior trial. Trials 2019; 20:173. [PMID: 30885242 PMCID: PMC6423831 DOI: 10.1186/s13063-019-3260-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2018] [Accepted: 02/27/2019] [Indexed: 11/16/2022] Open
Abstract
Background A long-acting prodrug of nalbuphine, nalbuphine sebacate, has been developed for meeting the unmet medical need of long-acting analgesics. Naldebain® (nalbuphine sebacate) has been developed as a new premedication for postoperative pain management. The primary objective of this study is to determine the efficacy and safety of a single dose of intramuscular Naldebain® in patients scheduled to undergo elective laparotomy. Methods/design A total of 110 patients will be recruited and randomized into two treatment groups. Group 1 receives a single dose of Naldebain® intramuscularly 24 ± 12 h prior to surgery. Group 2 receives intravenous patient-controlled analgesia (PCA) with fentanyl through 48 h postsurgery. Both groups will have follow-up observations until the final visit (day of discharge, day 6–30). The primary efficacy endpoint is to assess time-specific pain intensity calculated as the area under the curve (AUC) of a visual analog scale at individual time points and by using total AUC. Safety endpoints—including incidence of treatment, emergent adverse events, and percentage of abnormality from baseline to final visit—in vital signs, laboratory tests, and injection site evaluations will also be analyzed. Statistical analyses will be performed on the data to compare the two groups. Discussion Post-laparotomy pain can have a harmful effect on patient recovery; therefore, a slow-release formulation that can cover at least 7 days of analgesic effect is required. This study will demonstrate whether a single use of Naldebain® is not less efficacious than PCA with fentanyl for pain management as a non-inferior trial. Trial registration NCT03296488.
