Multicomponent solid dispersion as a formulation strategy to improve drug permeation
Multicomponent solid dispersions (MSD)s are frequently proposed as efficient drug delivery systems to improve drug solubility and bioavailability. In this study, the effects of specific excipients, such as mannitol, inulin, poly(methyl methacrylate-co-methacrylic)acid (PMMA) and cellulose acetate…

Liquisolid pellets: A pharmaceutical technology strategy to improve the dissolution rate of…
Liquisolid pellets (LPs) prepared by extrusion-spheronization are promising delivery systems to improve the dissolution rate of poorly water-soluble drugs. However, developing LPs for high dose drugs (e.g. antiretroviral ritonavir, RTV) is a major challenge due to technical and quality constraints.…

Modelling the Effect of Process Parameters on the Wet Extrusion and Spheronisation of High-Loaded…
The aim of the present study was to develop an alternative process to spray granulation in order to prepare high loaded spherical nicotinamide (NAM) pellets by wet extrusion and spheronisation. Therefore, a quality by design approach was implemented to model the effect of the process parameters of…

Evaluation of a Methylcellulose and Hyaluronic Acid Hydrogel as a Vehicle for Rectal Delivery of…
Biologics have changed the management of Inflammatory Bowel Disease (IBD), but there are concerns regarding unexpected systemic toxicity and loss of therapeutic response following administration by injection. Local delivery of biologics directly to the inflamed mucosa via rectal enema administration…

Designing robust immediate release tablet formulations avoiding food effects for BCS class 3 drugs
Food induced viscosity in the gastrointestinal tract is reported to reduce the bioavailability of tablets containing BCS class 3 drugs, mainly by retarding their disintegration and dissolution of the active pharmaceutical ingredient. The role of formulation factors in minimizing this negative food…

Non-aqueous formulations for ram and screen extrusion-spheronisation
The use of non-aqueous cellulose-based formulations for extrusion-spheronisation (E-S) is investigated. A 10 wt% hydroxypropyl cellulose/isopropyl alcohol solution (HPC/IPA) was identified as a suitable sticky liquid binder for preparing non-aqueous pastes. Preliminary tests were performed on a…

Improved Dissolution and Oral Bioavailability of Valsartan Using a Solidified Supersaturable…
To improve the dissolution and oral bioavailability of valsartan (VST), we previously formulated a supersaturable self-microemulsifying drug delivery system (SuSMED) composed of Capmul® MCM (oil), Tween® 80 (surfactant), Transcutol® P (cosurfactant), and Poloxamer 407 (precipitation inhibitor) but…

Implication of Quantitative Selection of Each Excipient in Product Development
Excipients’ role in designing different dosage forms does not require any introduction. These are the additives that are added to the formulation along with pharmacologically active substance. The main purpose of adding…

Edible solid foams as porous substrates for inkjet-printable pharmaceuticals
The aim of this study was to investigate new porous flexible substrates, i.e., solid foams that would serve as a carrier with a high ink absorption potential for inkjet printable pharmaceuticals. Propranolol hydrochloride was used as a model active pharmaceutical ingredient (API). Pharmaceutically…

Surface engineered excipients: III. Facilitating direct compaction tableting of binary blends…
irect compaction tableting, a desired manufacturing option, is infeasible for blends containing fine cohesive poorly-compactable APIs at higher drug loadings. In this study, the feasibility of using fine, dry coated excipients is investigated instead of dry coating of the APIs, as was done…
