The purpose of this work was to introduce a new concept of coated pellets containing chitosan microspheres loaded with didadosine for oral administration, aiming at reducing the frequency of administration and improving the bioavailability by a suitable release profile. Chitosan microspheres were produced under fluidized bed, followed by extrusion and spheronization to obtain pellets with a mea...

Poly(DL-lactide-co-glycolide) (PDLLGA) and poly(L-lactide-co-glycolide) (PLLGA) copolymers were prepared by bulk ring opening polymerization of lactide and glycolide and characterized by GPC, FTIR, 1H NMR and DSC. Copolymers with different molar masses at a constant lactide/glycolide ratio were used for preparation of bovine serum albumin (BSA)-loaded microparticles by the double emulsion w/o/w...

Introduction: Treatment of lung diseases is one of the major healthcare challenges. Ferulic acid (FA), a phenolic compound with well-established antioxidant and anti-inflammatory properties, has shown promising therapeutic potential against the pulmonary disorders; however, low bioavailability may negatively affect its efficiency. This, prompted us to incorporate FA into the nanostructured ...

   Oral pH sensitive drug delivery systems are of utmost importance as these systems deliver the drug at specific part of the gastrointestine (GI) as per the pH of GI, resulting in improved patient therapeutic efficacy and compliance. The pH range of fluids in various segments of the GI tract may provide environmental stimuli for drug release. The aim of this study was to design buoyant beads c...

Purpose: Enalapril maleate (EPM), was used for hypertension and congestive heart failure. In this way, an innovative delivery system with mPEG–PCL was synthesized and the release profile of the EPM from the drug-loaded polymersomes was evaluated. Methods: Di-block methoxy)-poly (ethylene glycol) - Poly (caprolactone) (mPEG-PCL) copolymers were synthesized and used to prepare of polymersom...

Introduction: Nonsteroidal anti-inflammatory drugs are the most commonly used drugs to reduce pain and inflammation. Aceclofenac is a newer derivative of diclofenac with less gastrointestinal complications. The objective of the present study was to evaluate the toxicity profile of sustain release aceclofenac injection in rats at three dose levels, ranging from 2 to 10 mg/kg body weight. Mater...

Abstract Purpose: our goal is to reduce the release rate of methotrexate (MTX) and increase cell death efficiency. Methods: Carboxylated multi-walled carbon nanotubes (MWCNT-COOH) were functionalized with MTX as a cytotoxic agent, FA as a targeting moiety and polyethylene amine (PEI) as a hydrophilic agent. Ultimately, MWCNT-MTX and MWCNT-MTX-PEI-FA were synthesized. Methotrexate re...
