Application of Drug Aggregation to Solubilize Antimicrobial Compound and Enhancing its Bioavailability.

With the progress and advancement in discovery of novel antimicrobial drugs, efficient solubility plays an important component for a drug to express its out-turn effectively. A biocompatible neutral/non-ionic surfactant, Triton X-100 (Tx-100), was successfully employed to solubilize an antibiotic drug, sulfamethazine (SMZ), through micellization process. The association process of Tx-100 toward SMZ was confirmed through the characteristic spectral change in absorption and emission spectroscopy. The morphological behavior of the complex was studied from small angle neutron scattering (SANS). Changes in size(s) and charge(s) of the micelles were monitored using zeta (z) potential technique. This present study emphasized the molecular mechanism and characteristics of Tx-100 as an effective drug solubilizing and carrier agent. Thus, the drug-loaded micellar system can enhance cellular uptake and increase the antibacterial effects of drugs in the biological system(s).
