A wide variety of pharmaceutical products, including pellets, granules, capsules, powders, and crystals are often coated. The procedure of coating tablets is a complex process that results in the forming of a thin layer around the tablet. This layer is in the range of 20 to 200 μm in thickness, or around 1 to 9% of the initial weight of the tablet.

Enhanced blend uniformity and flowability of low drug loaded fine API blends via dry coating: The…
Although previous research demonstrated improved flowability, packing, fluidization, etc. of individual powders via nanoparticle dry coating, none considered its impact on very low drug loaded blends. Here, fine ibuprofen at 1, 3, and 5 wt% drug loadings (DL) was used in multi-component blends to…

Coatings of Cyclodextrin/Citric-Acid Biopolymer as Drug Delivery Systems: A Review
In the early 2000s, a method for cross-linking cyclodextrins (CDs) with citric acid (CTR) was developed. This method was nontoxic, environmentally friendly, and inexpensive compared to the others previously proposed in the literature. Since then, the CD/CTR biopolymers have been widely used as a…
