PHYSICAL PROPERTY a yellow clear liquid.

PHARMACOLOGY Ofloxacin is a broad spectrum fluoroquinolone antibacterial. It is active against most Gram-positive and Gram-negative bacteria, like E.coli, Salmonella, Pseudomonas aeruginosa, Klebsiella, Proteus, Shigella, Staphylococci, Streptococci, Bacillus anthracis, Corynebacterium and etc. It is also active against most anaerobic bacteria, Mycobacteria, Mycoplasmas, Rickettsias, and the Protozoan Plasmodium falciparum.

Ofloxacin is bactericidal. The plasma concentrations for bactericidal and bacteriostatic effects are either the same or 2 to 4 times higher in bactericidal concentration. The antibacterial effect is not inhibited by the population of the pathogens or the presence of serum. However, urine with PH less than 5 or the increased level of Magnesium ions will adversely affect the antibacterial activities. There is no incompatibility with beta-lactam antibiotics and aminoglycosides.

(1) Ofloxacin can be inhibited by chemicals or feed additives with cations (Al3+,Mg2+,Ca2+,Fe2+,Zn2+). It may result in lower plasma concentration and thus leading to reduced antibacterial activities.

(2) Ofloxacin will also decrease the clearance of Theophylline and Caffeine and this will increase the serum level of the 2 chemicals.

(3) Rifampicin, Chloramphenicol,Thiamphenicol and Florfenicol may have antagonistic effects with Ofloxacin. 

(4) Probenecid will reduce the urinary secretion of Ofloxacin. The plasma concentration is not necessarily increased.
