Ofloxacin
Ofloxacin containing ofloxacin is a synthetic 4-fluoroquinolone antibacterial agent with bactericidal activity against a wide range of Gram-negative and Gram-positive organisms. Ofloxacin is thought to exert bactericidal effect by inhibiting DNA gyrase, an essential enzyme that is a critical catalyst in the duplication, transcription and repair of bacterial DNA. Following oral administration ofloxacin is rapidly and well absorbed from G.I. tract. The bioavailability of ofloxacin in the tablet formulation is almost 100%. It is widely distributed into body tissues and fluid. The half-life is about 4.6 to 6.9 hours. Up to 80% of an oral dose of ofloxacin is eliminated in the urine as the parent compound within 48 hour.
General dosage recommendations: The dose of ofloxacin is determined by the type and severity of the infection. The dosage range for adults is 200 mg to 800 mg daily. Up to 400 mg may be given as a single dose, preferably in the morning, larger doses should be given as two divided doses. Ofloxacin tablets should be swallowed with liquid; they should not be taken within two hours of intake of magnesium/aluminium containing antacids or iron preparations since reduction of absorption of ofloxacin can occur.Enteric fever: For adults 200 mg, every 12 hours, for 5 days. For children 15 mg/kg/day in 2 divided doses for 3 days.Shigellosis: 400 mg single dose.Multi-drug-resistant tuberculosis: 400 mg twice daily along with conventional  anti-tuberculosis drugs.Lower respiratory tract infection: 400 mg daily, increasing, if necessary, to 400 mg twice daily.Uncomplicated Urinary Tract Infections: A single dose of 200/400 mg.Uncomplicated urethral and cervical gonorrhoea: A single dose of 400 mg.Non-gonococcal urethral and cervicitis: 400 mg daily in single or divided doses.Complicated Urinary Tract Infection: 200/400 mg/day for 7 days.Impaired liver function: The excretion of ofloxacin may be reduced inpatients with severe hepatic dysfunction.Children: Ofloxacin is usually not indicated for use in children or growing adolescents.Elderly: No adjustment of dosage is required in the elderly.Ofloxacin Eye & Ear Drops-Eye: Instill 1 drop in the affected eye(s) every 2 to 4 hours for the first two days and then 4 times daily. The length of treatment should not exceed ten days.Ear: Instill 1-2 drops in the affected ear(s) twice daily or as needed.
Antacids containing magnesium, aluminium or calcium may decrease absorption of Rutix. Iron or Zinc may decrease oral absorption of Rutix.
Ofloxacin should not be used in-patients with known hypersensitivity to 4-fluoroquinolone antibacterials. It is contraindicated in-patients with a history of epilepsy or with a lowered seizure threshold. Ofloxacin is usually contraindicated in children or growing adolescents and in pregnant or breast feeding women.
