Description
Ofloxacin is quinolone antibiotics. It is useful for the treatment of a number of bacterial infections. Its chemical formula is C18H20FN304 and molecular weight is 361.37.
Clinical Pharmacology
Ofloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It is a DNA gyrase inhibitor. DNA gyrase is an essential bacterial enzyme that maintains the superhelical structure of DNA. DNA gyrase is required for DNA replication and transcription, DNA...
Ofloxacin is a racemic mixture, which consists of 50% levofloxacin (the biologically active component) and 50% of its mirror image or enantiomer dextrofloxacin. It is extremely active against Gram negative organisms and less active against Gram positive organism. Organisms susceptible to ofloxacin i...
Gram positive - Enterococcus faecalis, Staphylococcus epidermidis including methicillin resistant strains, Staphylococcus saprophyticus, Streptococcus agalactiae; Gram negative - Aeinetobacter spp, Aeromonas hydrophila, Camphylobacter jejuni, Citrobacter freundii, Enterobacter cloacae, Haemophilus p...
Anaerobes - Bacteroides fragilis, Clostridium spp, Gardnerella vaginalis, Peptostreptococci;
Other organisms - Legionella pneumophila, Mycoplasma pneumoniae, Mycobacterium tuberculosis, M. leprae, Ureaplasma urealyticum.
Pharmacokinetics
Ofloxacin is well absorbed when given orally. Time to peak plasma concentration: 1-2 hr. The plasma protein binding of ofloxacin is about 31% and the plasma elimination half-life is about 6-8 hrs. Ofloxacin is widely distributed in the tissues and body fluids viz, lungs, skin, blister fluid, cervix,...
Contraindication
Hypersensitivity to ofloxacin or other members of the quinolone group; or any component of the medication.
Precaution
It is used with caution in patients with epilepsy or other CNS disease which could predipose seizures and then use with caution in patients with renal impairment, failure to respond to an ophthamic antibiotic after 2-3 days may indicate in the presence of resistant organism or another causative agen...
Adverse Effects
It has common side effects including vomiting, diarrhoea, headache and rash. Other serious adverse effects include tendon rupture, numbness due to nerve damage, seizure and psychosis. The severe or irreversible side effects include sinus tachycardia, hallucinations, Stevens Johnson Syndrome. Ofloxac...
Drug Interaction
Azlocillin, cimetidine and probenecid may increase serum levels. Forcarnet and NSAIDs have been associated with the increased risk of seizures with some quinolones. Serum levels of some quinolones are increased by loop diuretic administration. The hypoprothrombinemic effects of warfarin is enhanced ...
Ofloxacin can chelate alkaline earth and transition metal cations. Administration of quinolones with antacids containing calcium, magnesium, or aluminum, with sucralfate, with divalent or trivalent cations such as iron, or with multivitamins containing zinc may substantially interfere with the absor...
Storage
Store below 30°C in cool, dry place. Protect from light and moisture. Keep out of reach and sight of children.
