  • Adjustment of Rheological Properties for Veterinary Suspensions

    Adjustment of Rheological Properties for Veterinary Suspensions

    Oral suspensions, or drenches, are a popular and common approach to overcoming the many obstacles of administering medicines to animals. Formulating solid dosage forms into suspensions enables line extensions of existing products for various animal species. Suspensions can be administered orally by drench guns or syringes, and can be mixed into feed or metered by dosing pumps into drinking water. The selection of a suitable stabilizer to adjust the required rheological properties is a major challenge in the development of suspensions. The goal of this study was to develop an oral suspension for animals with optimal stability, administration, and palatability.

  • Animal Health - Joint Health Tablets

    Animal Health - Joint Health Tablets

    Simplify the Manufacturing of Joint Health Tablets for Dogs: A Case Study with Green-Lipped Mussel Extract. With a prevalence of over 20%, osteoarthritis, or degenerative joint disease, is the most common form of joint disease in dogs. Green-lipped mussel (GLM) powder is widely used for prevention and treatment of osteoarthritis and may reduce, or even eliminate, the need for conventional medical therapy—NSAID’s in particular.

  • Compression of Probiotics for Companion Animals

    Compression of Probiotics for Companion Animals

    Probiotics, defined as “live microorganisms which when administered in adequate amounts confer a health benefit on the host,” indicate promising potential for the companion animals. Normally probiotics are filled into capsules or sachets; however, these dosage forms pose challenges for administration to animals. These factors make it worth considering direct compression of probiotics into tablets.

  • Dispersible Cellulose Navigator

    Dispersible Cellulose Navigator

    VIVAPUR® MCG is used as a suspending agent, emulsifier, opacifier, and thickener for oral suspensions, veterinary drenches, sprays (nasal, oral, or topical), reconstitutable powders, creams, gels, and lotions. This Dispersible Cellulose Navigator details the various available grades of VIVAPUR® MCG and their applications.

  • Influence of Different Lubricants on Tableting Characteristics and Dissolution Behavior

    Influence of Different Lubricants on Tableting Characteristics and Dissolution Behavior

    Apart from their desired effect of reducing the ejection force and punch adhesion, lubricants also have a considerable influence on the tablet hardness, disintegration, and dissolution times due to their inherent hydrophobicity. This study aimed to investigate the influence of the lubricant molecular structure on the aforementioned characteristics.

  • Performance of MCC Spheres and Sugar Spheres in a Multi-particulate Omeprazole Formulation

    Performance of MCC Spheres and Sugar Spheres in a Multi-particulate Omeprazole Formulation

    Robust and inert, spherical carriers are a prerequisite for the manufacture of multi-particulate dosage forms. In this study, spheres composed of microcrystalline cellulose (VIVAPUR® MCC SPHERES) were compared with sugar spheres.

  • The Effect of Silicification on the Roller Compaction Performance of Microcrystalline Cellulose

    The Effect of Silicification on the Roller Compaction Performance of Microcrystalline Cellulose

    Roller compaction, or dry granulation, is a manufacturing method for pharmaceutical and nutraceutical tablets that continues to gain importance. In order to achieve the desired granule properties, it is vital to use efficient binder-filler systems, which enable easy compaction, reproducible milling results, and high re-compactibility during the final tableting step. This study examines the effect of silicification on the roller compaction performance of microcrystalline cellulose.

  • VIVAPUR® MCG: A Powerful Stabilizer for Nasal Sprays

    VIVAPUR® MCG: A Powerful Stabilizer for Nasal Sprays

    Dispersible cellulose is a multifunctional and commonly used stabilizer for nasal sprays. VIVAPUR® MCG forms a three-dimensional coherent network of insoluble cellulose fibrils. All particles are kept homogenously within the gelled network. During agitation in the delivery device, the fibrils arrange themselves in the direction of the movement. The network loosens up and the viscosity decreases.
