Bioavailability enhancement
Tinctures or oily solutions
Tinctures, as oily solutions, are an ancient mode of preparation of plant extracts, but are still very actual and attractive, especially for cannabinoid formulations. With a straightforward development, they can easily be developed. They are also very convenient for the patients who can take a few…

Amorphous Solid Dispersions of Felodipine and Nifedipine with Soluplus®: Drug-Polymer Miscibility…
The objective of this study was to investigate thermodynamic and kinetic miscibility for two structurally similar model compounds nifedipine (NIF) and felodipine (FEL) when formulated as amorphous solid dispersions (ASDs) with an amphiphilic polymer Soluplus®.
Thermodynamic miscibility was…

Cilostazol Solubilization and Stabilization Using a Polymer-Free Solid Dispersion System
The development of pH-independent drugs is difficult because it involves improvements in their solubility and dissolution (%) in solubilizer. In the present study, the pH-independent cilostazol (CLT) was formulated for enhanced solubility and dissolution (%) and for maintaining stability with…

Thermal Stability of Amorphous Solid Dispersions
Amorphous solid dispersion drug delivery systems (ASD DDS) were proved to be efficient for the enhancement of solubility and bioavailability of poorly water-soluble drugs. One of the major keys for successful preparation of ASD is the selection of appropriate excipients, mostly polymers, which have…

Development of a Pediatric Mini-Tablet Formulation for Expedited Preclinical Studies
Multiple considerations are essential to address the main challenges of dose flexibility and patient adherence in pediatric drug development, particularly for oncology. Mini-tablets, 2 mm in diameter, were manufactured using a rotary tablet press at a set weight and compression force level. The…

Mucoadhesive nanostructured lipid carriers as a cannabidiol nasal delivery system for the treatment…
The therapeutic potential of cannabidiol (CBD) has been explored to treat several pathologies, including those in which pain is prevalent. However, the oral bioavailability of CBD is low owing to its high lipophilicity and extensive first-pass metabolism. Considering the ability of the nasal route…

Molecular Simulation and Statistical Learning Methods toward Predicting Drug–Polymer Amorphous Solid…
Amorphous solid dispersions (ASDs) have emerged as widespread formulations for drug delivery of poorly soluble active pharmaceutical ingredients (APIs). Predicting the API solubility with various carriers in the API–carrier mixture and the principal API–carrier non-bonding interactions are critical…

Lipid-based formulations: winning strategy for oral bioavailability enhancement
Many drugs exhibit poor solubility and/or permeability leading to weak oral bioavailability. To overcome these issues different technologies have been developed. Among them, lipid-based formulation (LBF) is a worth-considering option as it can be used from the very beginning of drug development to…
