Ciprofloxacin is bactericidal and acts by inhibiting the A subunit of DNA gyrase, (topoisomerase) which is essential in the reproduction of bacterial DNA.
Ciprofloxacin is highly active in vitro against most Gram-negative aerobic bacteria, including Enterobacteriaceae, Haemophilus, Neisseria and Pseudomonas aeruginosa. Ciprofloxacin is also active in vitro against many Gram-positive aerobic bacteria including penicillinase-producing and nonpenicillinase-producing and methicillin-resistant Staphylococci. Many strains of Streptococci are relatively resistant to the drug.
Rapid absorption. Wide distribution into body fluids and tissues except CSF. Metabolized in the body and eliminated mainly by kidneys.
Half-life is about 4 hours.
Crosses into foetal blood and is excreted into breast milk.

Caution should be exercised during concurrent administration of Antacids, Theophylline and Probenecid and in patients with renal impairment.
The safety and effectiveness of Ciprofloxacin in children, adolescents (less than 18 years of age), pregnant women, and lactating women have not been established.


Concurrent administration of Ciprofloxacin with Theophylline may lead to elevated serum concentrations of Theophylline and prolongation of its eliminations half-life.
Concurrent administration of Ciprofloxacin with Antacids, Sucralfate or divalent and trivalent cations such as iron may substantially interfere with the absorption of Ciprofloxacin, resulting in serum and urine levels considerably lower than desired. Probenecid interferes with renal tubular secretion of Ciprofloxacinand produces increase in the level of Ciprofloxacin in the serum.
Use in Pregnancy and Lactation:
Since Ciprofloxacin causes arthropathy in immature animals, it should not be used in pregnant women, lactating women (Ciprofloxacin in secreted in milk) and children below 18 years.
