Course: Lyophilization Technology: Product, Process And Systems (September 22-24, 2014)
Freeze drying experts BTL present a three-day course covering the science and application of lyophilization.
WHITE PAPERS & CASE STUDIES
Recommended Mixing Equipment For Ophthalmic Preparations
Pharmaceutical manufacturers rely on a range of high speed mixers to accomplish dispersion and emulsification.
Are Yield Stress And Creep Similar?
By Robert G. McGregor, General Manager, Brookfield Engineering Laboratories, Inc.
Creep is related to yield stress in the sense that the material starts to flow because the yield stress has been exceeded. The onset of creep behavior occurs only when the yield stress threshold has been crossed. So in this sense, the two are clearly related to one another, but how do pharmaceutical manufacturers anticipate the flow problems related to these parameters?
A Mesoporous Silica Carrier Optimized For Liquisolid And Lipid-Based Formulations
Syloid® XDP silicas are mesoporous, amorphous, silica gel excipients with a unique morphology that create an excellent solid porous carrier for pharmaceutical formulations. The combined adsorption capacity, porosity, particle size, and density provides a tool to create formulations which can expedite manufacturing and improve efficacy of the final dosage form.
Enhancing Stability In Nutraceutical Products
Nutraceuticals are natural products that are used to provide medical or physiological benefits.
Viscosity Flow Curve Tells All
Characterizing any material for flow behavior involves testing it over a range of shear rates relevant to how it is processed in manufacturing or how it is used by the consumer. Ointments, for example, are used to coat human body parts like skin, lips, finger/toe nails, hair, eyeballs, etc. The coating action is such that the medicinal mixture, once applied to the surface of the object, spreads as it is rubbed into place. Therefore, a relevant viscosity test would employ shear rates that mimic this type of spreading action.
Challenges & Opportunities: Encapsulation Of Liquid & Semi-Solid Formulations Into Oral Capsules
The encapsulation of liquids and semi-solids provides solutions for convenient delivery through improved oral absorption of poorly water-soluble drugs.
