Special Issue Information

Dear Colleagues,

Nano-enabled medicinal products have been widely accepted in the field of biomedical innovation. Owing to their unique physicochemical properties, it has been expected that nanomedicines could meet specific health challenges. However, when compared to the extensive research activities in this field, the number of clinically approved nanomedicines is still rather limited. One of the reasons may be the lack of proper correlation of physicochemical properties with their biological effects. Another issue is reflected in the ambiguous regulation of these products and their case-by-case evaluation. Leading EU and US regulatory and scientific bodies have acknowledged that the lack of established methods to provide reliable preclinical data represents the bottleneck in the process of bringing promising nanomedicines to the market. 

Therefore, this Special Issue aims to address some of the mentioned challenges and to collect pieces of knowledge on the performance of existing and new test methods and their application in the field of nanomedicine, targeting proper and reliable characterization of critical quality attributes and safety assessment of nanomedicines, supporting the regulatory decision making and facilitating the translation of these innovative products towards clinical applications.

In this Special Issue, both original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  • Innovative formulation strategies of nano-enabled drug delivery systems
  • Nanomedicines & Nanosimilars
  • Methodological gaps in characterization of nanomedicines and nanocarriers
  • Critical quality attributes (CQAs) of nanomedicines/nanocarriers
  • Preclinical assessment of nanomedicines/nanocarriers
  • Orthogonal & complementary techniques in nanomedicine development
  • Bio-nano interactions
  • Safety assessment of nanomedicines/nanocarriers
  • Characterization protocols for nanomedicines (experimental setting, data interpretation)
  • Pharmacokinetics of nanomedicines
  • Biodistribution of nanomedicines and nanocarriers
  • In vitro-(in silico)-in vivo correlation
  • Nanomedicines and nanocarriers in clinical trials

We are pleased to invite researcher and other interested parties in the field of nanomedicines to contribute to the Pharmaceutics Special Issue Quality Requirements for Nanomedicines: From Early Development to the Market.

The topical use of sunscreens is recommended for avoiding the damaging effects of UV radiation. However, improvements are still needed in the existing products to enhance their photoprotection effectiveness and safety. This involves minimizing the use of chemical UV filters while providing enhanced and prolonged photoprotection. This work investigated novel sunscreen formulations and their UV protection effects by encapsulating Uvinul® A, Tinosorb® S, and Uvinul® T150 into nanostructured lipid carriers (NLCs) based on bacuri butter and raspberry seed oil. First, the impact of critical formulation and process parameters on NLCs’ particle size was evaluated using a 22 Face Centered Central Composite Design. Then, formulations were evaluated in terms of critical quality factors, in vitro skin permeation, and in vitro and in vivo photoprotection activities. The developed NLCs-containing formulations exhibited appropriate size (122–135 nm), PdI (<0.3), encapsulation efficiency (>90%), and drug content (>80%), which were preserved for at least 90 days under different stability conditions. Moreover, these NLCs-based formulations had equivalent skin permeation to emulsion-based controls, and the addition of NLCs into sunscreen cream bases in the optimum proportion of 20% (w/w) resulted in enhanced UVA and UVB photoprotection levels, despite a 10% reduction in the total filters content. Altogether, these results describe the application of nanoencapsulated organic UV filters in innovative sunscreen formulations to achieve superior photoprotection and cosmeceutical properties.
