Short communicationExpedition of in vitro dissolution and in vivo pharmacokinetic profiling of sulfur nanoparticles based antimicrobials

•In vitro dissolution and in vivo pharmacokinetics of sulfur nanoparticles were attempted.•α-SNPs release from its PEGylated shell following first order release kinetics.•β-SNPs in contrast follow the zero order release kinetics.•SNPs exhibit good in vitro-in vivo pharmacokinetic correlation.

A comprehensive pharmacokinetic profiling of novel drugs and therapeutics is a definite prerequisite of drug discovery and development. The present study expedites the in vivo and in vitro pharmacokinetic properties of colloidal sulfur nanoparticles (SNPs). In vitro dissolution properties of SNPs have been demonstrated and compared with the in vivo pharmacokinetic parameters of rabbit (Oryctolagus cuniculus) serum sample. The present study was also aimed at developing levels of correlation between in vitro and in vivo pharmacokinetic parameters. Cumulative results of the proposed study also suggest good in vitro-in vivo correlation of these novel nanocolloids and suggest their immediate profiling as an antimicrobial drug.
