The impact of the degree of intimate mixing on the compaction properties of materials produced by crystallo-co-spray drying
(2020)
Direct compression remains one of the most favourable methods available to produce tablet compacts due to its simplicity, efficiency and cost effectiveness however, the technique still remains unsuitable for the majority ...
Physicochemical Characterization of a Co-Amorphous Atorvastatin-Irbesartan System with a Potential Application in Fixed-Dose Combination Therapy
(2021)
The aim of this study was to characterize a 1:1 molar ratio of a pharmacologically relevant co-amorphous atorvastatin-irbesartan (ATR-IRB) system obtained by quench cooling of the crystalline ATR/IRB physical mixture for ...
High-Pressure Dielectric Studies-a Way to Experimentally Determine the Solubility of a Drug in the Polymer Matrix at Low Temperatures
(2021)
In this work, we employed broad-band dielectric spectroscopy to determine the solubility limits of nimesulide in the Kollidon VA64 matrix at ambient and elevated pressure conditions. Our studies confirmed that the solubility ...
Green Synthesis of Lidocaine Ionic Liquids and Salts: Mechanisms of Formation and Interactions in the Crystalline and Supercooled States
(2020)
Mechanochemistry has been recognized as an optimal route for the synthesis of ionic liquids incorporating active pharmaceutical ingredients (API-ILs) as it eliminates the need for large volumes of solvents and purification ...
Carbohydrate-based Trojan microparticles as carriers for pulmonary delivery of lipid nanocapsules using dry powder inhalation
(2020)
This study proposes lipid nanocapsules (LNCs)-based Trojan particles made by entrapping 59 ± 3 nm LNCs in carbohydrate-based microparticles via spray drying. This work focused on optimisation of maintenance of the nanocarrier ...
Anticrystal Engineering of Ketoprofen and Ester Local Anesthetics: Ionic Liquids or Deep Eutectic Mixtures?
(2020)
Ionic liquids (ILs) and deep eutectic mixtures (DEMs) are potential solutions to the problems of low solubility, polymorphism, and low bioavailability of drugs. The aim of this work was to develop and investigate ketoprofen ...
Mechanochemical activation with cyclodextrins followed by compaction as an effective approach to improving dissolution of rutin
(2020)
Rutin is one of the most important flavonoids with poor bioavailability. This work aimed at addressing the issue of poor biopharmaceutical performance of rutin by applying a combination of complexation with secondary ...
Identification and Pharmaceutical Characterization of a New Itraconazole Terephthalic Acid Cocrystal
(2020)
The crystallization of poorly soluble drug molecules with an excipient into new solid phases called cocrystals has gained a considerable popularity in the pharmaceutical field. In this work, the cocrystal approach was ...
Submerged Eutectic-Assisted, Solvent-Free Mechanochemical Formation of a Propranolol Salt and Its Other Multicomponent Solids
(2021)
Salt preparation via a solid-state reaction offers a solution to challenges posed by current pharmaceutical research, which include combining development of novel forms of active pharmaceutical ingredients with greener, ...
An Enteric-Coated Polyelectrolyte Nanocomplex Delivers Insulin in Rat Intestinal Instillations when Combined with a Permeation Enhancer
(2020)
The use of nanocarriers is being researched to achieve oral peptide delivery. Insulin-associated anionic polyelectrolyte nanoparticle complexes (PECs) were formed that comprised hyaluronic acid and chitosan in an optimum ...
