Ciproxy 3 gm is an intravenous (IV) formulation of ciprofloxacin, a broad-spectrum antibiotic belonging to the fluoroquinolone class. It is primarily used to treat severe or complicated bacterial infections, including urinary tract infections (UTIs), lower respiratory tract infections, skin and soft tissue infections, intra-abdominal infections, bone and joint infections, and typhoid fever. Ciprofloxacin works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication, transcription, repair, and recombination. This action leads to the death of susceptible bacteria. The typical adult dosage for severe infections is 400 mg administered intravenously every 8 to 12 hours, depending on the severity and type of infection. The infusion should be administered over 60 minutes to minimize the risk of local IV site reactions. Caution is advised in patients with a history of convulsive disorders, and the drug should be used with caution in patients with renal impairment. Common side effects include nausea, diarrhea, rash, and potential central nervous system effects such as dizziness and confusion. Ciproxy 3 gm is manufactured by OS
