Beuflox (Ciprofloxacin)
Therapeutic Group: Anti Bacterial
Description
Ciprofloxacin is a synthetic 4-quinolone derivative with bactericidal activity against a wide range of gram-positive and gram-negative organism. It is active against most gram-negative aerobic bacteria including Enterobacteriaceae and Pseudomonas aeruginosa. Ciprofloxacin is also active against gram-positive aerobic bacteria including penicillinase producing, non-penicillinase producing and methicillin resistant Staphylococci. However many strains of Streptococci are relatively resistant to the drug. The bactericidal activity of Ciprofloxacin results from interference with the enzyme DNA gyrase needed for the synthesis of bacterial DNA. The mode of action of Ciprofloxacin is different from other antibiotics like penicillins, cephalosporins, aminoglycosides, tetracyclines and for this reason it is observed that organisms resistant to these antibiotics are susceptible to Ciprofloxacin. Ciprofloxacin is well absorbed from the GIT after oral administration and it is widely distributed into the body tissues and fluid. The half-life of Ciprofloxacin is 3.5 - 4.5 hours. About 30-50% of an oral dose of Ciprofloxacin is excreted in the urine within 24 hours as unchanged drug and active metabolites.
Indication
Ciprofloxacin is indicated for the treatment of the following infections caused by sensitive bacteria:
Severe systemic infections: e.g; septicemia, bacteremia, peritonitis, infections in immunosuppressed patients with haematological or solid tumors and in patients in intensive care unit with specific problems such as infected burns.

Use in Pregnancy and Lactation
Reproduction studies performed in rats and rabbits using parenteral and oral administration did not reveal any evidence of teratogenicity, impairment of fertility or impairment of pre or postnatal development. However, as with other quinolones, Ciprofloxacin has been shown to cause arthropathy in immature animals and therefore, its use during pregnancy is not recommended. Studies in rats have indicated that Ciprofloxacin is secreted in milk, administration to nursing mothers is thus not recommended.
