Intranasal Delivery of a Silymarin Loaded Microemulsion for the Effective Treatment of Parkinson’s…
A mucoadhesive microemulsion of lipophilic silymarin (SLMMME) was developed to treat Parkinson’s disease (PD). Optimization of the SLM microemulsion (ME) was performed using Central Composite Design (CCD). The composition of oil, surfactant, co-surfactant, and water was varied, as per the design, to…

Clarithromycin and Pantoprazole Gastro-Retentive Floating Bilayer Tablet for the Treatment of…
Bilayer/multilayer tablets have been introduced to formulate incompatible components for compound preparations, but they are now more commonly used to tailor drug release. This research aimed to formulate a novel gastro-retentive tablet to deliver a combination of a fixed dose of two drugs to…

Tailored anti-biofilm activity – Liposomal delivery for mimic of small antimicrobial peptide
The eradication of bacteria embedded in biofilms is among the most challenging obstacles in the management of chronic wounds. These biofilms are found in most chronic wounds; moreover, the biofilm-embedded bacteria are considerably less susceptible to conventional antimicrobial treatment than the…

In Situ Co-Amorphization of Olanzapine in the Matrix and on the Coat of Pellets
In situ amorphization is a promising approach, considered in the present work, to enhance the solubility and dissolution rate of olanzapine, while minimizing the exposure of the amorphous material to the stress conditions applied during conventional processing. The production of pellets by…

Combining drug salt formation with amorphous solid dispersions – a double edged sword
Glass transition temperature (Tg) is important for amorphous compounds because it can have implications on their physical and chemical stability. With drugs that possess ionizable acidic or basic groups, salt formation is a potential strategy to reduce re-crystallization tendency through Tg …

Atomic Layer Coating to Inhibit Surface Crystallization of Amorphous Pharmaceutical Powders
Preventing crystallization is a primary concern when developing amorphous drug formulations. Recently, atomic layer coatings (ALCs) of aluminum oxide demonstrated crystallization inhibition of high drug loading amorphous solid dispersions (ASDs) for over 2 years. The goal of the current study was to…

Smart nano-in-microparticles to tackle bacterial infections in skin tissue engineering
Chronic wounds (resulting from underlying disease, metabolic disorders, infections, trauma, and even tumours) pose significant health problems. In this work, microparticles, based on polysaccharides (maltodextrin or dextran) and amino acids, and doped with antibacterial nanoparticles (CuO or ZnO…

Charge converting nanostructured lipid carriers containing a cell-penetrating peptide for enhanced…
Hypothesis
The aim of this study was the development of nanostructured lipid carriers (NLCs) decorated with a polycationic cell-penetrating peptide (CPP). A coating with polyphosphates (PP) enables charge conversion at target cells being triggered by the membrane bound enzyme intestinal alkaline …

Downstream Processing of Amorphous and Co-Amorphous Olanzapine Powder Blends
The work evaluates the stability of amorphous and co-amorphous olanzapine (OLZ) in tablets manufactured by direct compression. The flowability and the compressibility of amorphous and co-amorphous OLZ with saccharin (SAC) and the properties of the tablets obtained were measured and compared to those…

Particle Engineering of Innovative Nanoemulsion Designs to Modify the Accumulation in Female Sex…
Particle engineering of nanosized drug delivery systems (DDS) can be used as a strategic tool to influence their pharmacokinetics after intravenous (i.v.) application by the targeted adaptation of their particle properties according to the needs at their site of action. This study aimed to…
