Tocilizumab-coated solid lipid nanoparticles loaded with cannabidiol as a novel drug delivery strategy for treating COVID-19: A review.

ABSTRACT: Commonly used clinical strategies against coronavirus disease 19 (COVID-19), including the potential role of monoclonal antibodies for site-specific targeted drug delivery, are discussed here. Solid lipid nanoparticles (SLN) tailored with tocilizumab (TCZ) and loading cannabidiol (CBD) are proposed for the treatment of COVID-19 by oral route. TCZ, as a humanized IgG1 monoclonal antibody and an interleukin-6 (IL-6) receptor agonist, can attenuate cytokine storm in patients infected with SARS-CoV-2. CBD (an anti-inflammatory cannabinoid and TCZ agonist) alleviates anxiety, schizophrenia, and depression. CBD, obtained from Cannabis sativa L., is known to modulate gene expression and inflammation and also shows anti-cancer and anti-inflammatory properties. It has also been recognized to modulate angiotensin-converting enzyme II (ACE2) expression in SARS-CoV-2 target tissues. It has already been proven that immunosuppressive drugs targeting the IL-6 receptor may ameliorate lethal inflammatory responses in COVID-19 patients. TCZ, as an immunosuppressive drug, is mainly used to treat rheumatoid arthritis, although several attempts have been made to use it in the active hyperinflammatory phase of COVID-19, with promising outcomes. TCZ is currently administered intravenously. It this review, we discuss the potential advances on the use of SLN for oral administration of TCZ-tailored CBD-loaded SLN, as an innovative platform for managing SARS-CoV-2 and related infections.

Project description:Diabetes mellitus (DM) is the most prevalent cause of diabetic retinopathy (DRP). DRP has been recognized for a long time as a microvascular disease. Many drugs were used to treat DRP, including vildagliptin (VLD). In addition to its hypoglycemic effect, VLD minimizes ocular inflammation and improves retinal blood flow for individuals with type 2 diabetes mellitus. Nevertheless, VLD can cause upper respiratory tract infections, diarrhea, nausea, hypoglycemia, and poor tolerability when taken orally regularly due to its high water solubility and permeability. Effective ocular administration of VLD is achieved using solid lipid nanoparticles (SLNPs), which improve corneal absorption, prolonged retention, and extended drug release. Ocuserts (OCUs) are sterile, long-acting ocular dosage forms that diminish the need for frequent dosing while improving residence time and stability. Therefore, this study intends to develop VLD solid lipid nanoparticle OCUs (VLD-SLNPs-OCUs) to circumvent the issues commonly associated with VLD. SLNPs were prepared using the double-emulsion/melt dispersion technique. The optimal formula has been implemented in OCUs. Optimization and development of VLD-SLNPs-OCUs were performed using a Box-Behnken Design (BBD). VLD-SLNPs-OCUs loading efficiency was 95.28 ± 2.87%, and differential scanning calorimetry data (DSC) showed the full transformation of VLD to an amorphous state and the excellent distribution in the prepared OCUs matrices. The in vivo release of VLD from the optimized OCUs after 24 h was 35.12 ± 2.47%, consistent with in vitro drug release data of 36.89 ± 3.11. The optimized OCUs are safe to use in the eye, as shown by the ocular irritation test. VLD-SLNPs-OCUs provide extended VLD release, an advantageous alternative to conventional oral dose forms, resulting in fewer systemic adverse effects and less variation in plasma drug levels. VLD-SLNPs-OCUs might benefit retinal microvascular blood flow beyond blood glucose control and may be considered a promising approach to treating diabetic retinopathy.

Project description:Glaucoma is a progressive optic neuropathy characterized by a rise in the intraocular pressure (IOP) leading to optic nerve damage. Bimatoprost is a prostaglandin analogue used to reduce the elevated IOP in patients with glaucoma. The currently available dosage forms for Bimatoprost suffer from relatively low ocular bioavailability. The objective of this study was to fabricate and optimize solid lipid nanoparticles (SLNs) containing Bimatoprost for ocular administration for the management of glaucoma. Bimatoprost-loaded SLNs were fabricated by solvent evaporation/ultrasonication technique. Glyceryl Monostearate (GMS) was adopted as solid lipid and poloxamer 407 as surfactant. Optimization of SLNs was conducted by central composite design. The optimized formulation was assessed for average particle size, entrapment efficiency (%), zeta potential, surface morphology, drug release study, sterility test, isotonicity test, Hen's egg test-chorioallantoic membrane (HET-CAM) test and histopathology studies. The optimized Bimatoprost-loaded SLNs formulation had an average size of 183.3 ± 13.3 nm, zeta potential of -9.96 ± 1.2 mV, and encapsulation efficiency percentage of 71.8 ± 1.1%. Transmission electron microscopy (TEM) study revealed the nearly smooth surface of formulated particles with a nano-scale size range. In addition, SLNs significantly sustained Bimatoprost release for up to 12 h, compared to free drug (p < 005). Most importantly, HET-CAM test nullified the irritancy of the formulation was verified its tolerability upon ocular use, as manifested by a significant reduction in mean irritation score, compared to positive control (1% sodium dodecyl sulfate; p < 0.001). Histopathology study inferred the absence of any signs of cornea tissue damage upon treatment with Bimatoprost optimized formulation. Collectively, it was concluded that SLNs might represent a viable vehicle for enhancing the corneal permeation and ocular bioavailability of Bimatoprost for the management of glaucoma.
