Overview
DESCRIPTION Ciprofloxacin Ophthalmic Solution is a synthetic, sterile, multiple dose, antimicrobial for topical ophthalmic use. Ciprofloxacin is a fluoroquinolone antibacterial active against a broad spectrum of gram-positive and gram-negative ocular pathogens. It is available as the monohydrochloride monohydrate salt of...
Mechanism of Action
CLINICAL PHARMACOLOGY Systemic Absorption: A systemic absorption study was performed in which Ciprofloxacin Ophthalmic Solution was administered in each eye every two hours while awake for two days followed by every four hours while awake for an additional 5 days. The maximum reported plasma concentration of ciprofloxacin was less than 5 ng/mL. The mean concentration was usually less than 2.5 ng/mL. Microbiology : Ciprofloxacin has in vitro activity against a wide range of gram-negative and gram-positive organisms. The bactericidal action of ciprofloxacin results from interference with the enzyme DNA gyrase which is needed for the synthesis of bacterial DNA.
Indications
- INDICATIONS AND USAGE Ciprofloxacin Ophthalmic Solution is indicated for the treatment of infections caused by susceptible strains of the designated microorganisms in the conditions listed below: Corneal Ulcers: Pseudomonas aeruginosa Serratia marcescens * Staphylococcus aureus Staphylococcus epidermidis Streptococcus pneumoniae Streptococcus (Viridans Group) * Conjunctivitis: Haemophilus influenzae Staphylococcus aureus Staphylococcus epidermidis Streptococcus pneumoniae *Efficacy for this organism was studied in fewer than 10 infections.
Common Doses
- Refer to label
Dosage
DOSAGE AND ADMINISTRATION Corneal Ulcers: The recommended dosage regimen for the treatment of corneal ulcers is two drops into the affected eye every 15 minutes for the first six hours and then two drops into the affected eye every 30 minutes for the remainder of the first day. On the second day, instill two drops in the affected eye hourly. On the third through the fourteenth day, place two drops in the affected eye every four hours. Treatment may be continued after 14 days if corneal re-epithelialisation has not occurred.
Contraindications
- CONTRAINDICATIONS A history of hypersensitivity to ciprofloxacin or any other component of the medication is a contraindication to its use. A history of hypersensitivity to other quinolones may also contraindicate the use of ciprofloxacin.
Side Effects
- ADVERSE REACTIONS The most frequently reported drug related adverse reaction was local burning or discomfort. In corneal ulcer studies with frequent administration of the drug, white crystalline precipitates were seen in approximately 17% of patients ( see Precautions ). Other reactions occurring in less than 10% of patients included lid margin crusting, crystals/scales, foreign body sensation, itching, conjunctival hyperemia and a bad taste following instillation.
Interactions
- Drug Interactions: Specific drug interaction studies have not been conducted with ophthalmic ciprofloxacin. However, the systemic administration of some quinolones has been shown to elevate plasma concentrations of theophylline, interfere with the metabolism of caffeine, enhance the effects of the oral anticoagulant, warfarin, and its derivatives, and has been associated with transient elevations in serum creatinine in patients receiving cyclosporine concomitantly.
