Ciprofloxacin
It is a new fluoroquinolone antimicrobial agent with potent activity against a broad spectrum of gram-positive&gram-negative bacteria including Ps. acruginosa, Enterobacteriaceae and Staph aureus. Ciprofloxacin does not disturb normal anaerobic intestinal flora and, has significant post-antibiotic effect & thus prevents regrowth of bacteria. Its antibacterial spectrum is wider than that of aminoglycosides, third generation cephalosporins and other fluoroquinolones.Respiratory tract, Urinary tract, E.N.T., skin and soft tissue, Gastro intestinal tract, Intra- abdominal Gynaecological. Bone and joint and Severe systemic infections, Gonorrhoea. Ciprofloxacin 400 mg/200 ml IV infusion 12 hourly is indicated for systemic infection, lower respiratory tract infections, skin and skin structure infections, typhoid fever, severe/complicated urinary tract infections, surgical procedure.

Diarrhoea, vomiting, abdominal pain headache, restlessness and arthralgia.
