Drug Dev Ind Pharm 2024; 50:206-222. [PMID: 38334395 DOI: 10.1080/03639045.2024.2313538] [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: 06/30/2023] [Accepted: 01/29/2024] [Indexed: 02/10/2024]
Abstract
OBJECTIVE The development of Mirtazapine (MRT)-loaded aquasomes by co-precipitation sonication technique to boost the antidepressant potential of MRT. METHODOLOGY MRT-loaded aquasomes formulations were prepared using Box-Behnken design to investigate the effect of independent factors including sonication time (X1), sonication temperature (X2), and sugar concentration (X3) on the dependent variables as particle size and drug loading efficiency. The formulation of the optimized formula was verified by Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), and X-ray Powder Diffraction (XRPD). Furthermore, the morphology of the formula was evaluated by Transmission Electron Microscopy (TEM). The optimum MRT- loaded aquasomes was assessed for physiochemical properties, in vitro MRT release and in vivo antidepressant effects in mice model. RESULTS The results revealed that the optimized formula showed a small particle size of 202.7 ± 3.7 nm and a high loading efficiency of 77.65 ± 2.6%. Thermal DSC and XRPD studies demonstrated the amorphous nature of MRT-loaded aquasomes. The in vitro study demonstrated sustained release of F (opt) 88.16% after 8 h, compared with plain MRT release of 63.06% after 1 h. Mice treated with MRT-loaded aquasomes demonstrated reduced immobility time in behavioral analysis to 37% with MRT-loaded aquasomes, while plain MRT reduced it to 55%. CONCLUSION These results confirmed that the antidepressant effect of MRT was significantly boosted in formulated aquasomes, and thereby they provide a promising carrier nano vesicular system for effective delivery of MRT.

Abstract
Lactose is one of the most widespread excipients used in the pharmaceutical industry. Because of its water solubility and acceptable flowability, lactose is generally added into tablet formulation to improve wettability and undesirable flowability. Based on Quality by Design, a better understanding of the critical material attributes (CMAs) of raw materials is beneficial in guiding the improvement of tablet quality and the development of lactose. Additionally, the modifications and co-processing of lactose can introduce more-desirable characteristics to the resulting particles. This review focuses on the functionality, CMAs, applications, modifications and co-processing of lactose in tablets.

Abstract
The surfaces of cells and pathogens are covered with short polymers of sugars known as glycans. Complex N-glycans have a core of three mannose sugars with distal repeats of N-acetylglucosamine and galactose sugars terminating with sialic acid (SA). Long-range tough and short-range brittle self-adhesions were observed between SA and mannose residues, respectively, in ill-defined artificial monolayers. We investigated if and how these adhesions translate when the residues are presented in N-glycan architecture with SA at the surface and mannose at the core and with other glycan sugars. Two pseudotyped viruses with complex N-glycan shields were brought together in force spectroscopy (FS). At higher ramp rates, slime-like adhesions were observed between the shields, whereas Velcro-like adhesions were observed at lower rates. The higher approach rates compress the virus as a whole, and the self-adhesion between the surface SA is sampled. At the lower ramp rates, however, the complex glycan shield is penetrated and adhesion from the mannose core is accessed. The slime-like and Velcro-like adhesions were lost when SA and mannose were cleaved, respectively. While virus self-adhesion in forced contact was modulated by glycan penetrability, the self-aggregation of the freely diffusing virus was only determined by the surface sugar. Mannose-terminal viruses self-aggregated in solution, and SA-terminal ones required Ca2+ ions to self-aggregate. Viruses with galactose or N-acetylglucosamine surfaces did not self-aggregate, irrespective of whether or not a mannose core was present below the N-acetylglucosamine surface. Well-defined rules appear to govern the self-adhesion and -aggregation of N-glycosylated surfaces, regardless of whether the sugars are presented in an ill-defined monolayer, or N-glycan, or even polymer architecture.

Abstract
Vesicular drug delivery system can be defined as highly ordered assemblies consisting of one or more concentric bilayers formed as a result of self-assembling of amphiphilic building blocks in presence of water. Vesicular drug delivery systems are particularly important for targeted delivery of drugs because of their ability to localize the activity of drug at the site or organ of action thereby lowering its concentration at the other sites in body. Vesicular drug delivery system sustains drug action at a predetermined rate, relatively constant (zero order kinetics), efficient drug level in the body, and simultaneously minimizes the undesirable side effects. It can also localize drug action in the diseased tissue or organ by targeted drug delivery using carriers or chemical derivatization. Different types of pharmaceutical carriers such as polymeric micelles, particulate systems, and macro- and micromolecules are presented in the form of novel drug delivery system for targeted delivery of drugs. Particulate type carrier also known as colloidal carrier system, includes lipid particles, micro- and nanoparticles, micro- and nanospheres, polymeric micelles and vesicular systems like liposomes, sphingosomes, niosomes, transfersomes, aquasomes, ufasomes, and so forth.
