Review literature: (Auque et al., 2002) (Henry et al., 2002 ) (Krčméry and Naber, 1999) (Talan et al., 2004) (Simon und Stille, 1997).
Mechanism of Action of Ciprofloxacin
Ciprofloxacin is a fluoroquinolone antibiotic, which interferes with the bacterial DNA synthesis via inhibition of the DNA gyrase or topoisomerase II. Fluoroquinolone antibiotics are bactericidal.
Indications for Ciprofloxacin
Ciprofloxacin is active against a variety of bacteria:
- Gram-negative pathogens including Pseudomonas, Mycoplasma, Chlamydia,..
- Gram-positive pathogens, but not Pneumococci or Enterococci
- Some anaerobic bacteria
Urologic indications for ciprofloxacin are urinary tract infection (increasing resistance), prostatitis, acute pyelonephritis, epididymitis.
Pharmacokinetics of Ciprofloxacin
- Good bioavailability after oral administration, maximum concentration in serum after 60–90 min of oral administration.
- Good tissue penetration
- Half-life of 3–5 h, renal elimination.
Side Effects of Ciprofloxacin
- Gastrointestinal side effects: Nausea, vomiting, diarrhea, pseudomembranous colitis
- Neurotoxicity with headache, dizziness, psychosis and seizures.
- Allergy. Rarely serious allergic skin reactions.
- Photosensitization
- Orthopedic side effects: cartilage damage, tendon damage with spontaneous tendon rupture.
Interactions with Ciprofloxacin:
Do not give iron salts or magnesium or aluminum-containing antacids together with ciprofloxacin. Increasing concentrations of theophylline or methotrexate during treatment with ciprofloxacin. Increases creatinine if given in combination with cyclosporine. Increases warfarin or glibenclamid effect.
Contraindications to Ciprofloxacin
- Pregnancy and lactation
- Contraindicated in children under 5 years. Caution in children older than 5 years: cartilage damage.
Dosage of Ciprofloxacin
Dosage depends on the severity of the infection and renal function:
- Oral dosage: 250–500 mg p.o. 1-0-1
- Intravenous dosage: 200–400 mg i.v. 1-0-1
- Treatment of uncomplicated gonorrhea with a single dose 250 mg p.o.
