💊: My name is Ciprofloxacin.
I am a fluoroquinolone antibiotic, commonly known as Cipro.

👨🏻‍⚕️ What is your work?
💊: I am a bactericidal antibiotic.
I kill bacteria by interfering with their DNA replication and repair mechanisms.

👨🏻‍⚕️ Tell me about yourself.
💊:
I belong to the second-generation fluoroquinolones.
I am especially effective against Gram-negative bacteria, including Pseudomonas aeruginosa, and some Gram-positive organisms.
I am not reliable for anaerobes.
I have good oral bioavailability and can be used orally or intravenously.
---
👨🏻‍⚕️ What is your mechanism of action?
💊:
I inhibit DNA gyrase (topoisomerase II) and topoisomerase IV,
which prevents DNA replication, transcription, repair, and recombination, leading to bacterial cell death.

I undergo minimal hepatic metabolism.
Most of my activity remains unchanged in the body.

My half-life is about 4–5 hours.
⚠️ Dose adjustment is required in renal impairment.
