Special Issue Information

Dear Colleagues,

Coating is necessary for most pharmaceutical solid dosage forms, e.g., tablets, pellets, capsules and particles. Its functionalities include enhancing drugs’ physical and chemical properties, achieving taste masking and spatiotemporally modifying drug release behaviors. Currently, liquid spray coating (organic solvent and aqueous systems) is practically utilized in the industry to obtain the coating film with acceptable uniformity. However, the presence of liquid (organic solvent and water) may cause several problems, such as solvent residue and VOC emissions. Additionally, the liquid coating process is not suitable for vulnerable actives and newly developed drug delivery systems such as micro/nanoparticles and implants. In order to fulfill the demand of these actives and delivery systems, many studies have been performed both in designing new dry coating strategies and developing novel coating materials, e.g., cell membranes with expanded functionalities. Therefore, the main aim of this Special Issue is to present current research works focusing on coating techniques for pharmaceutics, particularly dry coating and coating strategies for micro-/nano drug delivery systems. Original research articles and review papers focusing on the coating materials, mathematical simulations, process analysis technology (PAT) and coating facilities will also be welcome.

Agglomerate formulations for dry powder inhalation (DPI) formed with fine particles are versatile means for the highly efficient delivery of budesonide. However, uncontrolled agglomeration induces high deposition in the upper airway, causing local side effects due to high mechanical strength, worse deagglomeration, and poor fine-particle delivery. In the present study, fine lactose was mechanically dry-coated prior to particle agglomeration, and the agglomerates were then spheroidized via ultrasonic vibration to improve their aerosol performance. The results showed that the agglomerate produced with the surface-enriched hydrophobic magnesium stearate and ultrasonic vibration demonstrated improved aerosolization properties, benefiting from their lower mechanical strength, less interactive cohesive force, and improved fine powder dispersion behavior. After dispersion utilizing a Turbuhaler® with a pharmaceutical cascade impactor test, a fine particle fraction (FPF) of 71.1 ± 1.3% and an artificial throat deposition of 19.3 ± 0.4% were achieved, suggesting the potential to improve the therapeutic outcomes of budesonide with less localized infections of the mouth and pharynx.
