Albumin-Coated Mesoporous Silica Nanoparticles of Docetaxel: Preparation, Characterization, and Pharmacokinetic Evaluation

The potential of albumin-coated hollow mesoporous silica nanoparticles (A-HMSNs) to optimize the chemotherapeutic efficacy of docetaxel (DTX) was explored. The synthesized A-DTX-HMSNs had a nanometric size range, offered large surface area with numerous pores, and offered high drug entrapment and loading, that is, 79.18% +/- 1.4% and 19.11% +/- 1.30%, respectively. Fourier transform infrared spectroscopy and differential scanning calorimetry studies confirmed drug loading and the presence of albumin onto the developed systems, and the drug release followed Higuchi profile. A-HMSNs significantly enhanced the pharmacokinetic profile of DTX by eightfold vis-a-vis the pure DTX. The enhanced plasma levels (C-max, T-max, area under the curve), prolonged drug release, long circulation time, lower clearance, hemocompatability, and substantially higher drug loading offered by these nanocarriers inherit promise of a safer and efficacious formulation of DTX.
