Characterization of Layered Pellets and the Role of Amorphized Amlodipine Besylate / Hydrochlorothiazide

Characterization of layered pellets forms the basis of advanced pharmaceutical pellet design. These pellets consist of inert cores coated with active drug layers. Their detailed analysis ensures uniformity, strength, and consistent drug release. Layered systems offer precise dosing, extended or modified release, and taste masking. When the solid-state properties of the drug are modified through […]

Cellulose-derived spherical activated carbon – sustainable nanoarchitectonics for efficient uremic toxin removal in pharmaceutical applications

Cellulose-Derived Spherical Activated Carbon Cellulose-derived spherical activated carbon offers a sustainable and efficient solution for adsorbing harmful compounds such as uremic toxins [1]. This carbon material is made from renewable cellulose, which is transformed into spherical particles and then activated to increase surface area and porosity. The spherical shape improves flow properties and reduces dust, […]

UV Imaging of MUPS Tablets: Stability, Functionality, and Outcomes

Introduction to UV Imaging of MUPS Tablets UV imaging of MUPS tablets (multiple unit pellet system) is a growing field in pharmaceutical research. These tablets combine many coated pellets into one compressed unit. After ingestion, the tablet breaks apart and releases the active pharmaceutical ingredient (API). Researchers explored whether multispectral UV imaging could track the […]

CELLETS® in Malodor Control Compositions: A Patent Overview

Introduction to Malodor Control Technology CELLETS® in malodor control compositions mark a new step in odor management. Unpleasant smells from sulfur compounds, volatile organic compounds, aldehydes, and acids are often hard to control. Even more challenging are complex fishy odors that do not come from amines. Traditional solutions often fall short in both efficiency and […]

Hot-Melt Coating Materials: Enhancing Pharmaceutical and Industrial Applications

Hot-melt coating materials improve efficiency and product quality in pharmaceutical and industrial manufacturing. They melt when heated and solidify quickly, forming strong, uniform coatings on various surfaces. As a result, manufacturers reduce production time, lower costs, and avoid using solvents. Furthermore, understanding wetting behavior and delamination is critical to optimize coating performance. For example, CELLETS® […]

Patent on hydroxynorketamine modified‑release dosage form for the use in the treatment of depression

Introduction The development of a hydroxynorketamine modified-release dosage form marks an important advance in neuropsychiatric therapy. Hydroxynorketamine (HNK), a ketamine metabolite, shows rapid antidepressant activity through mechanisms different from ketamine itself. It works mainly by modulating α7-nicotinic acetylcholine receptors and activating mTOR pathways. This targeted action makes HNK a strong candidate as an active pharmaceutical […]

Patent on methods of administering gamma-hydroxybutyrate compositions with divalproex sodium

Introduction Gamma‑hydroxybutyrate (GHB) is an endogenous neurotransmitter also used pharmaceutically—usually as sodium oxybate—for treating narcolepsy and related disorders. It exerts its therapeutic effects by modulating GABA_B receptors and promoting slow-wave sleep, alleviating cataplexy, and reducing excessive daytime sleepiness. Despite its efficacy, current twice-nightly dosing regimens present challenges: dose‑dumping in the presence of alcohol, variable pharmacokinetics […]

A regenerable microporous adsorbent based on microcrystalline cellulose for organic pollutants adsorption

Introduction Fixed-bed column adsorption is an essential process in modern water treatment systems, widely implemented due to its continuous operation, ease of design, and applicability in large-scale systems. In this method, a contaminant-laden liquid passes through a column packed with adsorbent material, facilitating efficient contaminant removal before discharge or reuse. While effective for many pollutants, […]
