Poloxamer 188 stabilized poly (ε-caprolactone) microspheres of voriconazole for targeting pulmonary aspergillosis.

ABSTRACT:

Aim

Voriconazole (VRZ) is highly effective in treating invasive pulmonary aspergillosis (IPA), in addition to hepatotoxicity. Therefore, the current study focuses on the development and characterization of voriconazole-loaded microspheres (VRZ@PCL MSPs) to augment pulmonary localization and antifungal efficacy.

Methods

VRZ@PCL MSPs were fabricated by using the o/w emulsion method. The optimized F3VRZ@PCL MSPs were subjected to physicochemical characterization, in vitro release, hemocompatibility, antifungal efficacy as well as pharmacokinetic and biodistribution evaluation.

Results

The optimized F3VRZ@MSPs exhibited a particle size (10.90 ± 2.61 µm), entrapment efficiency (19.35 ± 2.47%), drug loading (3.22 ± 0.41%) with sustained release behavior up to 24 h and hemoc
