In vitro pharmacodynamic properties of a fluoroquinolone pharmaceutical derivative: hydrochloride of ciprofloxacin-aluminium complex.
Some in vitro pharmacodynamic properties of a new aqueous soluble ciprofloxacin (CIPX) derivative, the hydrochloride of its aluminum complex: (HCl.CIPX)(3)Al, are reported. Although (HCl.CIPX)(3)Al had the same MIC as CIPX, the minimum bactericidal activity against Escherichia coli was 2-fold higher than that of CIPX and the rate of killing was slightly delayed compared with time-kill curves obtained with CIPX. (HCl.CIPX)(3)Al showed a longer post-antibiotic effect (PAE). As pharmacodynamic properties of CIPX are not drastically affected by being complexed with aluminium, the increased aqueous compatibility of the complex remains as the main formulation factor for liquid dosage forms.
