Zanocin 100 Tablet contains Ofloxacin 100 mg, a broad-spectrum fluoroquinolone antibiotic effective against a wide range of bacterial infections. It is indicated for the treatment of various infections caused by susceptible strains of bacteria, including respiratory tract infections, urinary tract infections, skin and soft tissue infections, gastrointestinal infections, and sexually transmitted diseases such as gonorrhea. Ofloxacin exerts its antibacterial effect by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for bacterial DNA replication, transcription, repair, and recombination, thereby preventing bacterial cell division and growth. Zanocin 100 is typically administered orally and should be taken as prescribed by a healthcare professional, with dosage and duration tailored to the specific infection and patient condition. It is important to complete the full course of therapy to prevent the development of bacterial resistance. Common side effects may include gastrointestinal disturbances such as nausea, diarrhea, and abdominal discomfort, as well as central nervous system effects like dizziness and headache. Caution is advised in patients with a history of tendon disorders related to fluoroquinolones, and it is contraindicated in individuals with known hypersensitivity to ofloxacin or other quinolones. Zanocin 100 should be used with caution in patients with renal impairment, and dosage adjustments may be necessary.
