Bestoflox-N Syrup

Side Effects of Bestoflox-N Syrup

Nausea, vomiting, abdominal pain, diarrhoea; headache, dizziness, insomnia, hallucinations; leucopenia and eosinophilia; vaginitis; dysgeusia; tendon damage and rupture; anorexia; tremor; photosensitivity; hypersensitivity reactions. Discontinue if psychiatric, neurological or hypersensitivity reactions occur. Potentially Fatal: Anaphylaxis; rarely seizures.

Drug Interactions

Probenecid decreases elimination. Antacids may reduce ofloxacin absorption, avoid for 2 hr either side of administration. Cimetidine may increase ofloxacin concentrations. Monitor blood glucose in patients on antidiabetic medication. Potentially Fatal: Corticosteroids may increase risk of tendon rupture. Increases effects of oral anticoagulants, ciclosporin, theophylline. Increased risk of seizures with NSAIDs. Avoid in patients taking QT prolonging medication (e.g. class Ia or III antiarrythmics, astemizole, terfenadine, cisapride, erythromycin, pentamidine, phenothiazines and some TCA).

Contraindications

Hypersensitivity to quinolones; pregnancy and lactation; prolongation of the QT interval; uncorrected hypokalaemia.

Mechanism of Action

Ofloxacin is a fluoroquinolone which inhibits bacterial topoisomerase IV and DNA gyrase enzymes required for DNA replication, transcription, repair and recombination. It has activity against a wide range of gram-negative and gram-positive microorganisms. Absorption: Rapidly and well absorbed from the GI tract (oral); peak plasma concentrations after 0.5-2 hr. Rate, but not extent, delayed by the presence of food. Distribution: Widely distributed into body fluids, CSF, tissues, bile (high concentrations); crosses the placenta and enters breast milk. Protein-binding: 20-32%. Metabolism: <10% of a single dose is metbolised. Converted to desmethyl and N-oxide metabolites; desmethylofloxacin has moderate antibacterial activity. Excretion: Via urine within 24-48 hr by tubular secretion and glomerular filtration (75-80% as unchanged, <5% as metabolites); via faeces (4-8%). Elimination is biphasic with half-lives of 4-5 hr and 20-25 hr; prolonged in renal impairment (15-60 hr).

Special Precautions

Epilepsy or other predisposition to seizures; known or suspected CNS disorders; renal, hepatic impairment; myasthaenia gravis; superinfection; children <18 yr; exposure to strong sunlight and UV light; ensure adequate hydration; elderly.
