Abstract
Repaglinide (RPG) belongs to the class of drugs known as meglitinides and is used for improving and maintaining glycemic control in the treatment of patients with Type 2 diabetes. RPG is a Class II drug (BCS) because of its high permeability and low water solubility. It also undergoes hepatic first-pass metabolism. The oral bioavailability of RPG is low (about 56 %) due to these drawbacks. Our aim in this study is to prepare two different nano-sized drug carrier systems containing RPG (nanoparticle: RPG-PLGA-Zein-NPs or nanoemulsion: RPG-NE) and to carry out a pharmacokinetic study for these formulations. We prepared NPs using PLGA and Zein. In addition, a single NE formulation was developed using Tween 80 and Pluronic F68 as surfactants and Labrasol as co-surfactant. The droplet size values of the blank-NE and RPG-NE formulations were found to be less than 120 nm. The mean particle sizes of blank-Zein-PLGA-NPs and RPG-Zein-PLGA-NPs were less than 260 nm. The Cmax and tmax values of RPG-Zein-PLGA-NPs and RPG-NE (523 ± 65 ng/mL and 770 ± 91 ng/mL; 1.41 ± 0.46 h and 1.61 ± 0.37 h, respectively) were meaningfully higher than those of free RPG (280 ± 33 ng/mL; 0.72 ± 0.28 h) (p < 0.05). The AUC0-∞ values calculated for RPG-Zein-PLGA-NPs and RPG-NE were approximately 4.04 and 5.05 times higher than that calculated for free RPG. These nanosized drug delivery systems were useful in increasing the oral bioavailability of RPG. Moreover, the NE formulation was more effective than the NP formulation in improving the oral bioavailability of RPG (p < 0.05).

The delivery of nanoparticles improves the pharmacokinetic properties of celecoxib to open a therapeutic window for oral administration of insoluble drugs. Biomed Chromatogr 2023; 37:e5552. [PMID: 36408991 DOI: 10.1002/bmc.5552] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 10/30/2022] [Accepted: 11/18/2022] [Indexed: 11/23/2022]
Abstract
A sensitive and reliable LC-MS/MS method is established and validated to determine the concentration of celecoxib, in the serum of cynomolgus monkey, using celecoxib-D7 as an internal standard. The pharmacokinetic process was investigated after giving Celebrex, celecoxib nanoparticles (CXB-NPs) and hyaluronic acid celecoxib nanoparticles (HA-CXB-NPs) by intragastric (i.g.) administration. Chromatographic separation was performed with a C18 column (2.1 × 100 mm, 2.6 μm) at 40°C with a mobile phase of 2‰ HCOOH in water and acetonitrile. The mass spectral acquisition was then performed in the multiple reaction monitoring mode, with negative ESI ion at m/z 380.0 → 316.0 and m/z 387.1 → 323.1 for celecoxib and celecoxib-D7, respectively. Good linearity was observed over the concentration range from 3 to 2,000 ng/ml (R2 = 0.9954). The intra- and inter-day precision and accuracy, matrix effect and extraction recovery, as well as stability, all met the determination requirements of biological samples. The pharmacokinetic parameters of Celebrex, CXB-NPs and HA-CXB-NPs were determined as: area under the curve, 1,855.98 ± 346.59, 1,908.00 ± 1,130.24 and 2,164.48 ± 657.47 h·ng/ml; peak concentration, 261.08 ± 113.26, 261.12 ± 94.67 and 263.34 ± 151.78 μg/L; time to peak concentration, 2.00 ± 1.22, 4.00 ± 0.00 and 3.60 ± 0.89 h; half-life, 4.39 ± 1.26, 2.33 ± 0.94 and 4.92 ± 3.13 h; relative bioavailability, 102.80 ± 49.62 and 116.63 ± 25.55%. The validated method was successfully applied to the pharmacokinetic study of celecoxib in cynomolgus monkey, after i.g. administration. The preparation of the nanoparticles of celecoxib and the modification of hyaluronic acid on the surface of nanoparticles could improve the bioavailability and prolong the circulation of celecoxib in vivo, which could lay the foundation for further development of celecoxib nanoparticles.

Drug delivery to the brain via the nasal route of administration: exploration of key targets and major consideration factors. JOURNAL OF PHARMACEUTICAL INVESTIGATION 2023; 53:119-152. [PMID: 35910081 PMCID: PMC9308891 DOI: 10.1007/s40005-022-00589-5] [Citation(s) in RCA: 33] [Impact Index Per Article: 33.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 06/30/2022] [Indexed: 01/06/2023]
Abstract
Background Cranial nerve-related diseases such as brain tumors, Alzheimer's disease, and epilepsy are serious diseases that continue to threaten human. Brain-related diseases are increasing worldwide, including in the United States and Korea, and these increases are closely related to the exposure to harmful substances and excessive stress caused by rapid industrialization and environmental pollution. Drug delivery to the brain is very important for the effective prevention and treatment of brain-related diseases. However, due to the presence of the blood-brain barrier and the extensive first-pass metabolism effect, the general routes of administration such as oral and intravenous routes have limitations in drug delivery to the brain. Therefore, as an alternative, the nasal-brain drug delivery route is attracting attention as a route for effective drug delivery to the brain. Areas covered This review includes physiological factors, advantages, limitations, current application status, especially in clinical applications, and the necessary factors for consideration in formulation development related to nasal-brain drug delivery. Expert opinion The nasal-brain drug delivery route has the advantage of enhancing drug delivery to the brain locally, mainly through the olfactory route rather than the systemic circulation. The nasal-brain lymphatic system has recently attracted attention, and it has been implied that the delivery of anticancer drugs to the brain nervous system is possible effectively. However, there are limitations such as low drug permeability, as well as nasal mucosa and the mucociliary system, as obstacles in nasal-brain drug delivery. Therefore, to overcome the limitations of nasal-brain drug delivery, the use of nanocarriers and mucoadhesive agents is being attempted. However, very few drugs have been officially approved for clinical application via the nasal-brain drug delivery route. This is probably because the understanding of and related studies on nasal-brain drug delivery are limited. In this review, we tried to explore the major considerations and target factors in drug delivery through the nasal-brain route based on physiological knowledge and formulation research information. This will help to provide a mechanistic understanding of drug delivery through the nasal-brain route and bring us one step closer to developing effective formulations and drugs in consideration of the key factors for nasal-brain drug delivery.

Abstract
Biological macromolecules have been widely used as biomedical carriers in treating non-small cell lung cancer (NSCLC) due to their biocompatibility, targeting, biodegradability, and antitumor efficacy. Nanotechnology has been used in clinics to treat many diseases, including cancer. Nanoparticles (NPs) can accumulate drugs into tumors because of their enhanced permeability and retention (EPR) effects. However, the lack of active targeting ligands affects NPs drug delivery. Arginine-glycine-aspartic (RGD), as a targeting ligand, has distinct advantages in targeting and safety. In the present study, an RGD peptide-modified nanogel called RGD−polyethylene glycol−poly (L-phenylalanine-co-L-cystine) (RGD−PEG−P (LP-co-LC−P (LP-co-LC) was investigated to deliver vincristine (VCR) as NSCLC therapy. The VCR-loaded targeted nanoparticle (RGD-NP/VCR) demonstrated excellent antitumor efficacy compared to the free drug (VCR) and untargeted nanoparticle (NP/VCR) without any significant side effects. RGD-NP/VCR has better tumor inhibition and fewer side effects, indicating its potential benefit in NSCLC treatment.

Abstract
Breast cancer is the most prevalent cancer in women around the world, having a sudden spread nowadays because of the poor sedentary lifestyle of people. Comprising several subtypes, one of the most dangerous and aggressive ones is triple-negative breast cancer or TNBC. Even though conventional surgical approaches like single and double mastectomy and preventive chemotherapeutic approaches are available, they are not selective to cancer cells and are only for symptomatic treatment. A new branch called nanotechnology has emerged in the last few decades that offers various novel characteristics, such as size in nanometric scale, enhanced adherence to multiple targeting moieties, active and passive targeting, controlled release, and site-specific targeting. Among various nanotherapeutic approaches like dendrimers, lipid-structured nanocarriers, carbon nanotubes, etc., nanoparticle targeted therapeutics can be termed the best among all for their specific cytotoxicity to cancer cells and increased bioavailability to a target site. This review focuses on the types and molecular pathways involving TNBC, existing treatment strategies, various nanotechnological approaches like exosomes, carbon nanotubes, dendrimers, lipid, and carbon-based nanocarriers, and especially various nanoparticles (NPs) like polymeric, photodynamic, peptide conjugated, antibody-conjugated, metallic, inorganic, natural product capped, and CRISPR based nanoparticles already approved for treatment or are under clinical and pre-clinical trials for TNBC.
