Current Drug Delivery - Volume 18, Issue 6, 2021

New technologies are currently investigated to improve the quality of foods by enhancing their nutritional value, freshness, safety, and shelf-life, as well as by improving their tastes, flavors and textures. Moreover, new technological approaches are being explored, in this field, to address nutritional and metabolism-related diseases (i.e., obesity, diabetes, cardiovascular diseases), to improve targeted nutrition, in particular Read More

Chemometrics is an important emerging discipline with unique charm formed by the intersection of mathematics, statistics, chemistry and computer science. The application of chemometrics in the field of pharmacy has injected fresh blood into the scientific research and clinical practice of medicine and has provided a sufficient scientific basis for drug analysis and content determination to solve the problem of ca Read More

Background: Exosomes, one of the extracellular vesicles, are widely present in all biological fluids and play an important role in intercellular communication. Due to their hydrophobic lipid bilayer and aqueous hydrophilic core structure, they are considered a possible alternative to liposome drug delivery systems. Not only do they protect the cargo like liposomes during delivery, but they are also less toxic and better Read More

Background: Fused Deposition Modelling (FDM) 3D printing has received much interest as a fabrication method in the medical and pharmaceutical industry due to its accessibility and cost-effectiveness. A low-cost method to produce biocompatible and biodegradable filaments can improve the usability of FDM 3D printing for biomedical applications. Objectives: The feasibility of producing low-cost filaments suitable for FDM 3D pr Read More

Introduction: At present, there are numerous researches on the migration of components in tablets and granules, however, the investigation in the pharmaceutical literatures concerning the effect of drying rate on the migration of water-soluble components of pellets is limited. Temperature and Relative Humidity (RH) are crucial parameters during the drying process, which is an essential step in the preparation of pellets via wet e Read More

Background: Discovering new chemotherapy drugs and techniques with the least side effects is one of the most important and challenging issues in recent years worldwide. Chlorambucil is an anticancer drug that is still commonly used as a primary treatment in treating some cancers, but it can cause side effects. Objective: In this study, we decided to use chitosan as a carrier to enhance the uptake of chlorambucil and reduce th Read More

Background: Doxycycline (DOX) is used in treating a bacterial infection, especially for periodontitis treatment. Objective: To reduce irritation of DOX for subgingival administration and increase the chemical stability and against enzymatic, the complex of α-cyclodextrin with DOX was prepared and loaded into injectable in situ forming implant based on PLGA. Methods: FTIR, molecular docking studies, X-ray diffraction, and differential Read More

Background: Poly Ionic Complex (PIC) nanogels are promising delivery systems with numerous attractions such as simple, fast, and organic solvent-free particle formation and mild drug loading conditions. Among polyelectrolytes, poly (L-amino acid) copolymers, such as poly (ethylene glycol)-block-poly (L-glutamic acid) copolymers (PEG-b-PGlu) are interesting biocompatible and biodegradable candidates bearing carboxylic aci Read More

Introduction: Nano drug delivery is a broad field of research on the development of novel nano- carrier systems for effective therapeutic delivery of drugs. Here, an anticancer drug, cisplatin (CDDP) conjugated Gold Nanoparticles (GNPs) via L-Lysine (Lys) linker. Methods: The produced nanodrug (GNPs-Lys-CDDP) was characterized by UV-Vis spectroscopy, Dynamic Light Scattering (DLS), Zeta potentials and electron force microsc Read More

Background: Amikacin is an aminoglycoside antibiotic used for many gram-negative bacterial infections like infections in the urinary tract, infections in brain, lungs and abdomen. Electrochemical determination of amikacin is a challenge in electroanalysis because it shows no voltammetric peak at the surface of bare electrodes. Objective: In this approach, a very simple and easy method for indirect voltammetric determination of a Read More

Background: Lipid nanocarriers have been widely tested as drug delivery systems to treat diseases due to their bioavailability, controlled release, and low toxicity. For the pulmonary route, the Food and Drug Administration favors the use of substances generally recognized as safe, as well as biodegradable and biocompatible to minimize the possibility of toxicity. Tuberculosis (TB) remains a public health threat worldwide, mainl Read More

Background: Levofloxacin has been recommended by the WHO for the treatment of pulmonary tuberculosis and inhalable delivery of levofloxacin can be advantageous over conventional delivery. Objective: This study aimed to develop and optimize inhalable levofloxacin Loaded Chitosan Nanoparticles (LCN). The objective was to achieve the mean particle size of LCN less than 300nm, sustain the drug release up to 24 h, a Read More

Background: Methotrexate (MTX) is a water-insoluble, anti-tumor agent that causes adverse effects like bone marrow suppression, chronic interstitial obstructive pulmonary disease, hepatotoxicity, leukopenia, interstitial pneumonitis and nephrotoxicity with slow drug release rate. Objective: The present study aimed to successfully incorporate MTX into novel-targeted Pluronic (PEOPPO- PEO tri-block co-polymer) F1 Read More

Background: Intranasal administration of biodegradable nanoparticles has been extensively studied for targeting the drug directly to CNS through the olfactory or trigeminal route bypassing the blood brain barrier. Objective: The objective of the present study was to optimize Clonazepam loaded PLGA nanoparticles (CLO-PNPs) by investigating the effect of process variables on the responses using 32 full factorial design. Me Read More

Introduction: In the working age population, Diabetic Macular Edema (DME) is the most common cause of visual loss. Purpose: The present study is aimed to assess the safety and efficacy of intravitreal injection of Ranibizumab (IVR) versus intravitreal Dexamethasone implant (IVD) in patients with DME in a tertiary care centre upto 4 months. Methods: This is a comparative, prospective, randomized study that was done on 140 Read More
