Interest in lipid based drug delivery has developed over the past decade fuelled by a better understanding of the multiple roles lipids may play in enhancing oral bioavailability. Moreover, the emergence of novel excipients with acceptable regulatory and safety profiles coupled with advances in formulation technologies have greatly improved the potential for successful lipid based formulations....
The aim of this work was to develop and evaluate solid lipid nanoparticles (SLN) containing all-transretinoic acid (ATRA) for topical delivery. SLN composed of coconut oil and curdlan improved the suspension instability of ATRA in aqueous solution. The photodegradation of ATRA by light was reduced by incorporation in SLN. The loading efficiency of ATRA in SLN was higher than 95% (w/w). The amou...
The present study was aimed at developing aqueous dispersion of Ketorolac-loaded solid lipid nanoparticles (SLN) by high speed stirring followed by ultrasonication technique and then incorporation into freshly prepared gel for transdermal delivery. A statistical central composite design was applied to study the effect of drug/lipid ratio and soya lecithin concentration on particle size and entr...
Various nanoparticles have been investigated as novel drug delivery systems, including solid lipid nanoparticles (SLNs). Due to their rapid clearance from systemic circulation, nanoparticles do not provide sustained action in most cases. Different strategies have been employed to overcome this problem. In this direction, the present study introduces erodible in-situ forming gel systems as poten...
Solid lipid nanoparticles (SLN) loaded with doxorubicin were prepared by solvent emulsification-diffusion method. Glyceryl caprate (Capmul)MCM C10) was used as lipid core, and curdlan as the shell material. Dimethyl sulfoxide (DMSO) was used to dissolve both lipid and drug. Polyethylene glycol 660 hydroxystearate (Solutol)HS15) was employed as surfactant. Major formulation parameters were optim...
Recently, the use of mammalian target of rapamycin (mTOR) inhibitors, in particular rapamycin (Rp), has been suggested to improve the treatment of neurodegenerative diseases. However, as Rp is a strong immunosuppressant, specific delivery to the brain has been postulated to avoid systemic exposure. In this work, we fabricated new Rp loaded solid lipid nanoparticles (Rp-SLN) stabilized with poly...
The two polyhydroxy surfactants polyglycerol 6-distearate (Plurol(®)Stearique WL1009 - (PS)) and caprylyl/capryl glucoside (Plantacare(®) 810 - (PL)) are a class of PEG-free stabilizers, made from renewable resources. They were investigated for stabilization of aqueous solid lipid nanoparticle (SLN) and nanostructured lipid carrier (NLC) dispersions. Production was performed by high pressure ho...
A series of aliphatic esters of the NSAID naproxen (NAP) were synthesised and encapsulated in solid lipid nanoparticles (SLN) to evaluate the influence of lipophilicity on drug loading and release, as well as physicochemical properties and stability of SLN. The lipophilicity of esters mainly showed to influence their affinity for the solid lipid matrix, modifying the drug release profile compar...
Raloxifene hydrochloride (RL-HCL) is an orally selective estrogen receptor modulator (SERM) with poor bioavailability of nearly 2% due to its poor aqueous solubility and extensive first pass metabolism. In order to improve the oral bioavailability of raloxifene, raloxifene loaded solid lipid nanoparticles (SLN) have been developed using Compritol 888 ATO as lipid carrier and Pluronic F68 as sur...
Sarcolipin (SLN) is a 31 amino acid integral membrane protein that regulates Ca-ATPase activity in skeletal muscle. Here, we report the three-dimensional structure and topology of synthetic SLN in lipid environments, as determined by solution and solid-state NMR spectroscopy. 2D solution NMR experiments were performed on SLN solubilized in sodium dodecyl sulfate (SDS) micelles. We found that SL...
