Pharmaceutical preformulation studies and paediatric oral formulations of sodium dichloroacetate
The purpose of this study was to develop liquid and solid paediatric formulations of sodium dichloroacetate (DCA) for the treatment of congenital lactic acidosis (CLA). In this work preformulation studies on the active molecule were performed to identify those physico-chemical properties of the drug…

An introduction to pharmaceutical film coatings
A wide variety of pharmaceutical products, including pellets, granules, capsules, powders, and crystals are often film coated. In this present article, we will concentrate on the film-coating of tablets.
The procedure of coating tablets is a complex process that results in the forming of a thin…

Designing pH-Responsive Biodegradable Polymer Coatings for Controlled Drug Release via Vapor-Based…
We present the design of a novel pH-responsive drug release system that is achieved by solventless encapsulation of drugs within a microporous membrane using a thin capping layer of biodegradable polymethacrylic anhydride (PMAH) coating. The coating was synthesized via a mild vapor polymerization…

Effect of Binder Attributes on Granule Growth and Densification
The rate and extent of granule growth and densification during high-shear wet granulation (HSWG) depends on a variety of formulation and process variables, including material attributes of critical formulation excipients, such as binders. The effects of known binder attributes to the rate and extent…

The central role of excipients in drug formulation
Active substances are rarely administered alone. For example, levothyroxine, a synthetic form of the thyroid hormone, indicated in the treatment of hypothyroidism, is administered at a very low dosage, ranging from 15 μg to 200 μg. These very small amounts of powder mean that it is not possible…
