Skin drug delivery systems with controlled release are suitable means for the local transfer of pharmaceutical compounds to the damaged and healthy layers of skin. Nanofibrous membrane prepares uniform moisture in the wound environment with less accumulation of fluid secretion due to its variable pore size. Electrospinning takes advantage of using herbal extracts in the form of electrospun nano...

In this study, seven-layer nanofiber structures consisting of polycaprolactone/ chitosan polymers loaded with methotrexate and 5-fluorouracil anti-cancer drugs, for controlled drug delivery, were produced and evaluated. For this purpose, the second, fourth and sixth layers were loaded with drug and placed between the drug-free layers. The surface morphology of drug-free and drug-loaded nanofibe...

To answer challenge of targeted and controlled drug release in oral delivery various materials were studied by different methods. In the present paper, controlled metal based drug (Pd(II) complex) release manner of β‑Lactoglobulin (β-LG) nanoparticles was investigated using mathematical drug release model in order to design and production of a new oral drug delivery system for gastrointestinal ...

Spanules are considered one of the most advantageous drug delivery systems. Multi-drug regimen is key benefit (capsules having granules.) constructed for release API (Drug) at different rates and times. The first immediate /slow-release pattern gives an initial which followed by a constant rate extended time.This will result in constantdrugsbeing available long time period. This doses form usef...

Attempts have been made to prepare nanoparticles based on poly(lactic-co-glycolic acid) (PLGA) and doxorubicin. Biological evaluation and physio-chemical characterizations were performed to elucidate the effects of initial drug loading and polymer composition on nanoparticle properties and its antitumor activity. PLGA nanoparticles were formulated by sonication method. Lactide/glycolide ratio ...

Objective(s): In this study, drug loaded electrospun nanofibrous mats were prepared and drug release and mechanism from prepared nanofibers were investigated.  Materials and Methods: Paclitaxel (PTX) loaded polylactic acid (PLA) nanofibers were prepared by electrospinning. The effects of process parameters, such as PTX concentration, tip to collector distance, voltage, temperature and flow rate...

      In order to enhance in vitro dissolution and content uniformity of poorly soluble drug glimepiride by preparing solid dispersions using modified solvent fusion method, solid dispersions of drug were prepared by modified fusion solvent method using PEG 6000 and PVP K25 (as carrier). Eight batches (F1-F8) were prepared by Factorial design (23) by taking three ...

Extended-release matrix tablets of diltiazem hydrochloride (DTZ) were prepared using waxy materials alone or in combination with Kollidon SR. Matrix waxy materials were carnauba wax (CW), bees wax (BW), cetyl alcohol (CA) and glyceryl monostearate (GMS). Dissolution studies were carried out by using a six stations USP XXII type 1 apparatus. The in vitro drug release study was done in 1000 ml ph...

Background and purpose: This study investigated the effect of different HLBs on these nanoparticles using spironolactone solid lipid nanoparticles. Materials and methods: The spironolactone loaded SLN was prepared by emulsion/solvent evaporation technique followed by ultrasonication. In this study, Palmitic acid was used as carrier. Different weight ratio of drug, carrier, Span60 and Tween80 w...
