Objective: In current research, solid lipid nanoparticles (SLN) are formulated for the anticancer drug, nilotinib, to conquer drawbacks associated with drug including low bioavailability and solubility. Methods: The formulation comprised of tripalmitin (lipid), poloxamer 188(surfactant) glyceryl palmitostearate (cosurfactant) by solvent evaporation technique. process variables SLN were optimize...

The influenza A virus M2 proton channel equilibrates pH across the viral membrane during entry and across the trans-Golgi membrane of infected cells during viral maturation. It is an important target of adamantane-family antiviral drugs, but drug resistance has become a critical problem. Two different sites for drug interaction have been proposed. One is a lipid-facing pocket between 2 adjacent...

The effects of vesicle size, lipid composition, and drug-to-lipid ratio on the biological activity of liposomal doxorubicin in mice have been investigated using a versatile procedure for encapsulating doxorubicin inside liposomes. In this procedure, vesicles exhibiting transmembrane pH gradients (acidic inside) were employed to achieve drug trapping efficiencies in excess of 98%. Drug-to-lipid ...

Nanostructured lipid carriers (NLCs), a lipid based colloidal carrier system, offer many advantages such as increase the solubility, improves the bioavailability and therapeutic efficacy. Incorporation of liquid lipid can improve the drug loading capacity in the NLCs. Valsartan is an antihypertensive drug with low oral bioavailability ranging from 10-35% because of poor solubility and extensive...

The purpose of this study was to offer a new insight into the microstructure changes during in vitro lipolysis of five lipid-based drug delivery formulations belonging to different lipid formulation types. Five lipid-based formulations of indomethacin were investigated using an in vitro lipolysis model. During lipolysis, microstructures of the intermediate phase formed by lipolytic products wer...

The objective of this study is to develop suitable formulations to improve the dissolution rate of poorly water soluble drugs. We selected lipid-based formulation as a drug carrier and modified the surface using positively charged chitosan derivative (HTCC) to increase its water solubility and bioavailability. Chitosan and HTCC-coated lipid particles had higher zeta-potential values than uncoat...

Angiopoietin-like proteins (ANGPTL) are a family of several proteins, which ANGPTL3, 4 and 8 involved in lipid metabolism. These discovered relatively recently, regulate the availability triglycerides for heart, skeletal muscles white brown adipose tissue depending on nutritional status body, thus contributing to maintenance energy homeostasis. gene mutations associated with significant reducti...

Oral aphthous stomatitis is a common disorder treated with the immunomodulatory drug Amlexanox (AMX), that was administered as mucoadhesive paste (Aphthasol®). This product discontinued by FDA in 2014 due to associated undesired adverse reactions of formulation. Here, we have developed AMX-loaded nanoliposome formulation potential alternative for localised oromucosal delivery AMX. Nanoliposomes...

Dorzolamide ophthalmic drop is one of the most common glaucoma medications but it has a short residence time in the eye. The aim of this study is to develop ocular dorzolamide HCl nanoliposomes (DRZ – nanoliposomes) and to evaluate their potential use for the treatment of ocular hypertension. Nanoliposomes were prepared using Reverse-phase evaporation vesicle (REV) and thin layer hydration (TLH...
