Influences of alcohol/polyols on interaction of moxifloxacin hydrochloride through cetyltrimethylammonium bromide at numerous temperatures and compositions

A study on the interaction of a fourth-generation antibiotic drug, moxifloxacin hydrochloride (MFH), with a cationic surfactant, such as cetyltrimethylammonium bromide (CTAB) in the aqueous solution of alcohol (1-propanol (1-PrOH)) and polyols (galactose/maltose), has been carried out using the conductivity measurement technique. The critical micelle concentration (cmc), micelle ionisation (α), counter ion binding (β), and thermodynamic properties (ΔGm0, ΔHm0, and ΔSm0) for the self-aggregation of MFH + CTAB mixture have been estimated in 1-PrOH/polyols solutions. The presence of 1-PrOH delays the MFH + CTAB micelle formation, whereas polyols create a congenial environment for the micelle formation. In 1-PrOH, the values of α experience a reduction with the increase of 1-PrOH concentration and temperature. The values of α were found to…
