Ciprofloxacin: Uses, Dosage, Side Effects and More

Introduction: What is Ciprofloxacin?

Ciprofloxacin is a broadspectrum antibiotic belonging to the fluoroquinolone class. It is primarily used to treat various bacterial infections by inhibiting the growth and reproduction of bacteria. Ciprofloxacin is effective against a wide range of gramnegative and some grampositive bacteria, making it a versatile option in the treatment of infections.

Uses of Ciprofloxacin

Ciprofloxacin is approved for several medical uses, including:

1. Urinary Tract Infections (UTIs): Effective against infections caused by E. coli and other bacteria.
2. Respiratory Tract Infections: Used for pneumonia and bronchitis.
3. Skin Infections: Treats infections caused by susceptible bacteria.
4. Gastrointestinal Infections: Effective against certain types of foodborne illnesses.
5. Bone and Joint Infections: Used in cases of osteomyelitis.
6. Anthrax Exposure: Prescribed as a preventive measure against inhalational anthrax.

How It Works

Ciprofloxacin works by targeting bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication and repair. By inhibiting these enzymes, ciprofloxacin prevents bacteria from reproducing and repairing their DNA, ultimately leading to cell death. In simpler terms, it stops bacteria from multiplying and spreading, helping the body to fight off the infection.

Dosage and Administration

The dosage of ciprofloxacin varies based on the type of infection and the patient's age.

• Adults: The typical dosage ranges from 250 mg to 750 mg, taken every 12 hours. For severe infections, higher doses may be prescribed.
• Pediatric Patients: Ciprofloxacin is generally not recommended for children under 18 unless absolutely necessary, as it may affect bone development. If prescribed, the dosage is based on the child's weight.

Ciprofloxacin can be administered in various forms, including:

• Tablets: Taken orally with or without food.
• Injectable Form: Administered intravenously in a hospital setting for severe infections.

Drug Interactions

Ciprofloxacin can interact with several medications, including:
