OFLOXACIN- ofloxacin_solution

CLINICAL PHARMACOLOGY
Serum, urine and tear concentrations of ofloxacin were measured in 30 healthy women at various time points during a ten-day course of treatment with ofloxacin ophthalmic solution. The mean serum ofloxacin concentration ranged from 0. 4 ng/mL to 1. Maximum ofloxacin concentration increased from 1. 1 ng/mL on day one to 1. 9 ng/mL on day 11 after QID dosing for 10 1/2 days. Maximum serum ofloxacin concentrations after ten days of topical ophthalmic dosing were more than 1000 times lower than those reported after standard oral doses of ofloxacin. Tear ofloxacin concentrations ranged from 5. 7 to 31 mcg/g during the 40 minute period following the last dose on day 11. Mean tear concentration measured four hours after topical ophthalmic dosing was 9. Corneal tissue concentrations of 4. 4 mcg/mL were observed four hours after beginning topical ocular application of two drops of ofloxacin ophthalmic solution every 30 minutes. Ofloxacin was excreted in the urine primarily unmodified. Ofloxacin has in vitro Cross-resistance has been observed between ofloxacin and other fluoroquinolones. There is generally no cross-resistance between ofloxacin and other classes of antibacterial agents such as beta-lactams or aminoglycosides. Ofloxacin has been shown to be active against most strains of the following organisms both in vitro see Indications and Usage AEROBES , GRAM - POSITIVE : AEROBES , GRAM - NEGATIVE : Staphylococcus aureus Enterobacter cloacae Staphylococcus epidermidis Haemophilus influenza Streptococcus pneumoniae Proteus mirabilis ANAEROBIC SPECIES : Pseudomonas aeruginosa Propionibacterium acnes Serratia marcescens * *Efficasy for this organism was studied in fewer than 10 infection The safety and effectiveness of ofloxacin ophthalmic solution in treating ophthalmologic infections due to the following organisms have not been established in adequate and well-controlled clinical trials.

WARNINGS
NOT FOR INJECTION. Ofloxacin ophthalmic solution should not be injected subconjunctivally, nor should it be introduced directly into the anterior chamber of the eye. There are rare reports of anaphylactic reaction /shock and fatal hypersensitivity reactions in patients receiving systemic quinolones, some following the first dose, including ofloxacin. Some reactions were accompanied by cardiovascular collapse, loss of consciousness, angioedema (including laryngeal, pharyngeal or facial edema), airway obstruction, dyspnea, urticaria, and itching. A rare occurrence of Stevens-Johnson syndrome, which progressed to toxic epidermal necrolysis, has been reported in a patient who was receiving topical ophthalmic ofloxacin. If an allergic reaction to ofloxacin occurs, discontinue the drug. Serious acute hypersensitivity reactions may require immediate emergency treatment. Oxygen and airway management, including intubation should be administered as clinically indicated.
