Ciprofloxacin is a type of antibiotic that belongs to a class of medications known as fluoroquinolones. Cipro is indicated for use in adults with various types of infections, including urinary tract infections, sinus infections, skin infections, bone and joint infections, diarrhea, typhoid fever, and lower respiratory tract infection that have susceptible bacteria. Cipro tablets consist of ciprofloxacin hydrochloride which is found as a faintly yellowish to light yellow crystalline substance. Cipro (ciprofloxacin) is available in 250 mg and 500 mg yellowish, film-coated tablets and 5% and 10% oral suspensions. When given as an oral tablet, the absolute bioavailability of ciprofloxacin is 70% and maximum serum concentrations occur 1 to 2 hours after oral dosing. The bioavailability of ciprofloxacin after oral administration might be affected by use of antacids, polymeric phosphate binders, sucralfate, and dairy products. The serum elimination half-life of ciprofloxacin is roughly four hours in people with normal renal function. In people with impaired kidney function, ciprofloxacin’s half life is slightly prolonged. Cipro is similar to the fluoroquinolone antibiotics levofloxacin, moxifloxacin and ofloxacin.
