n recent years there has been a growing interest in solid lipid-based systems, particularly in solid lipid microparticles (SLMs); however, only very few studies deeply investigated the dissolution behaviour of orally delivered-SLMs. The present study provides new insights about the release performance in different gastrointestinal fluids of SLMs containing a freely water soluble drug (caffeine, as BCS class I drug). Three different formulations of SLMs were prepared by spray congealing using...

A novel hybrid microparticulate system composed of poly(lactic-co-glycolic) acid (PLGA) nanoparticles and submicron medium-chain triglyceride (MCT) droplets was fabricated to overcome the pH-dependent solubility and precipitation challenges associated with a model poorly water-soluble weak base, cinnarizine (CIN). Molecular CIN was confined within both the lipid and polymer phase of PLGA-lipid hybrid (PLH) and PLGA-lipid-mannitol hybrid (PLMH) particles, which offered significant...

Abstract Hot-melt coating (HMC) as a solvent-free technology grants faster and more economic coating processes with reduced risk of dissolving the drug during the process. Moreover, traditional coating equipment can be modified to enable the HMC process. Despite the indubitable advantages and feasibility of the process, HMC is not well-known to pharmaceutical industry and its employment is still limited. The main aspect hindering the widespread application of this technique is the need of...
