Current Drug Delivery - Volume 19, Issue 1, 2022

Hormonal drugs are essential treatment options for some hormone-dependent or hormone- sensitive tumors. The common dosage forms of hormonal drugs have a short half-life. Hence, frequent administration is needed, which results in poor patient compliance. Nevertheless, using drug delivery technology, somatostatin analogues (SSAs) and gonadotropin-releasing hormone (GnRH) analogues are prepared into long-acti Read More

Alzheimer’s Disease (AD), a progressive and irreversible neurodegenerative disorder, is the most common form of dementia worldwide. Currently, there is no disease-modifying AD drug, and the development of effective treatments is made even harder by the highly selective nature of the Blood-Brain Barrier (BBB) that allows the passage only of molecules with specific chemicalphysical properties. In this context, nanomedi Read More

Background: Exenatide(EXE) is an anti-hyperglycemic agent approved for treating type 2 diabetes by the Food and Drug Administration(FDA). However, twice-daily injection of exenatide is inconvenient for most of the patients. Objective: In this study, biotinylated trimethylated chitosan(Bio-TMC) based nanoparticles were proposed to promote oral absorption of exenatide. Realizing the oral administration of exenatide is very Read More

Introduction: The amentoflavone (AMF) loaded polymeric sub-micron particles were prepared using supercritical antisolvent (SAS) technology with the aim of improving the anticancer activity of AMF. Methods: Zein and phospholipid mixtures composed of Hydrogenated Phosphatidylcholine (HPC) and egg lecithin (EPC) were used as carrier materials and, the effects of carrier composition on the product morphology and drug Read More

Background: The combination of photothermal therapy (PTT) and chemotherapy has proven to be a promising strategy for cancer treatment. Various nanomaterials have shown great potential in combination therapy, including gold, graphene oxide, iron oxide, and other nanoparticles. However, their undefinable toxicity in vivo greatly slowed down their development for clinical applications. Objective: The present work a Read More

Aim: In this work, to improve the solubility and bioavailability of the rosuvastatin (RSV) drug, chitosan-coated mesoporous silica nanoparticles (CS-MSNs) as a drug delivery system were fabricated. Methods: To do this, first MSNs with a maximum specific surface area were synthesized from sodium silicate as silica source and different molar ratios of cethyl trimethylammonium bromide (CTAB) and pluronics (P123, PEO20PPO Read More

Introduction: Hydrophilic polymers that swell or dissolve in aqueous media can have the potential to prepare controlled/sustained dosage forms for weakly acidic and poorly soluble drugs. Objective: The main objective of this study is to utilize Eudragit®E100 (EE) and Carbopol®971P NF (Cp) polymers and their salt forms for the preparation of a once-daily controlled-release matrix tablet for model drug, Ibuprofen (IB). Method Read More

Background: Albendazole (ABZ) is the drug of choice for the treatment of a variety of human and veterinary parasites. However, it has low aqueous solubility and low bioavailability. Cyclodextrins (CD) are pharmaceutical excipients with the ability to modulate the solubilization property of hydrophobic molecules. Objective: The aim of the study was to analyze through in vitro and in silico studies (Autodock Vina software and Read More

Introduction: Metformin, an anti-diabetic drug, has low bioavailability and short biological half-life. Thus, bioavailability enhancement and prolonged release of the drug are highly desirable. In this regard, we aimed to developed gastroretentive nanoparticles made of jackfruit seed starch (JFSS) loaded with metformin. Methods: Developed nanoparticles were optimized for various process variables and were further characterized. Read More

Introduction: Brucellosis is a zoonotic disease that is prevalent in livestock animals. The bacteria reside inside the macrophage cells of the host. The WHO has endorseda combination treatment therapy for brucellosis against the conventional monotherapy to avoid relapse and resistance. Therefore, we developed nanoparticles incorporating doxycycline and rifampicin in combination. Aim: The aim of the study is to develop Read More

Background: Rutin is available on the market as a topical formulation for the treatment of several conditions, such as internal bleeding, hemorrhoids, and varicose veins. However, these gels have low solubility and limited bioavailability due to their decreased lipid solubility. Objective: In this study, we aimed to synthesize potentially novel lipophilic rutin prodrugs. The suggested library of these rutin prodrugs includes ch Read More

Aim: The present research work was aimed to formulate fast disintegrating tablets (FDTs) of salbutamol sulphate (SBS) using a combination of a superdisintegrant and a subliming agent, optimize the formulation and evaluate the in vitro performance of the developed FDTs. Materials and Methods: A formulation of SBS FDT was developed using a combination of superdisintegrant - crospovidone and subliming agent - Amm Read More

Objectives: One of the promising strategies for effective HIV-1 vaccine design involves finding the polyepitope immunogens using T cell epitopes. Methods: Herein, an HIV-1 polyepitope construct (i.e., Nef-Tat-Gp160-P24) comprising of several epitopes from Nef, Tat, Gp160, and P24 proteins was designed. To improve its immunogenicity in BALB/c mice, cell-penetrating peptides (HR9 and MPG for DNA delivery, and LDP-NLS an Read More

Introduction: Typically, in situ forming implants utilize Poly (lactide- co- glycolide) (PLGA) as carrier and N-methyl-2-pyrrolidone (NMP) as solvent. However, it is essential to develop different carriers to release various drugs in a controlled and sustained manner with economic and safety considerations. Objective: The present study aims to evaluate the in-vitro release of Bupivacaine HCl from in situ forming systems as po Read More
