1 INDICATIONS AND USAGE Ciprofloxacin and dexamethasone, otic suspension is indicated for the treatment of infections caused by susceptible isolates of the designated microorganisms in the specific condition listed below: Acute Otitis Media (AOM) in pediatric patients (age 6 months and older) with tympanostomy tubes due to Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis , and Pseudomonas aeruginosa. ( 1 ) Acute Otitis Externa (AOE) in pediatric (age 6 months and older), adult and elderly patients due to Staphylococcus aureus and Pseudomonas aeruginosa . Ciprofloxacin and dexamethasone, otic suspension is a combination of ciprofloxacin, a fluoroquinolone antibacterial and dexamethasone, a corticosteroid, indicated for the treatment of infections caused by susceptible isolates of the designated microorganisms in the specific condition listed below: Acute Otitis Media (AOM) in pediatric patients (age 6 months and older) with tympanostomy tubes due to Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis , and Pseudomonas aeruginosa.

2 DOSAGE AND ADMINISTRATION Ciprofloxacin and dexamethasone, otic suspension is for otic use (ears) only, not for ophthalmic use, or for injection. ( 2.1 ) Shake well immediately before use. ( 2.1 ) Instill four drops into the affected ear twice daily, for seven days. ( 2 ) 2.1 Important Administration Instructions Ciprofloxacin and dexamethasone, otic suspension is for otic use (ears) only, and not for ophthalmic use, or for injection. Shake well immediately before use. 2.2 Dosage For the Treatment of Acute Otitis Media in Pediatric Patients (age 6 months and older) With Tympanostomy Tubes The recommended dosage regimen through tympanostomy tubes is as follows: • Four drops [equivalent to 0.14 mL of ciprofloxacin and dexamethasone otic suspension, (consisting of 0.42 mg of ciprofloxacin and 0.14 mg of dexamethasone)] instilled into the affected ear twice daily for seven days. • The suspension should be warmed by holding the bottle in the hand for one or two minutes to avoid dizziness, which may result from the instillation of a cold suspension. • The patient should lie with the affected ear upward, and then the drops should be instilled. • The tragus should then be pumped 5 times by pushing inward to facilitate penetration of the drops into the middle ear. • This position should be maintained for 60 seconds. Repeat, if necessary, for the opposite ear. • Discard unused portion after therapy is completed. For the Treatment of Acute Otitis Externa (age 6 months and older) The recommended dosage regimen is as follows: Four drops [equivalent to 0.14 mL of ciprofloxacin and dexamethasone, otic suspension, (consisting of 0.42 mg ciprofloxacin and 0.14 mg dexamethasone)] instilled into the affected ear twice daily for seven days. The suspension should be warmed by holding the bottle in the hand for one or two minutes to avoid dizziness, which may result from the instillation of a cold suspension. The patient should lie with the affected ear upward, and then the drops should be instilled. This position should be maintained for 60 seconds to facilitate penetration of the drops into the ear canal. Repeat, if necessary, for the opposite ear. Discard unused portion after therapy is completed.

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Potential for Microbial Overgrowth with Prolonged Use [see Warnings and Precautions (5.2) ] Most common adverse reaction was ear pruritus (1.5%).

In Phases II and III clinical trials, a total of 937 patients were treated with ciprofloxacin and dexamethasone, otic suspension. This included 400 patients with acute otitis media with tympanostomy tubes (AOMT) and 537 patients with AOE. The reported adverse reactions are listed below: Acute Otitis Media in Pediatric Patients with Tympanostomy Tubes The following adverse reactions occurred in 0.5% or more of the patients with non-intact tympanic membranes. Adverse Reactions Incidence (N = 400) Ear discomfort 3.0% Ear pain 2.3% Ear precipitate (residue) 0.5% Irritability 0.5% Taste Perversion 0.5% The following adverse reactions were each reported in a single patient: tympanostomy tube blockage; ear pruritus; tinnitus; oral moniliasis; crying; dizziness; and erythema. Acute Otitis Externa The following adverse reactions occurred in 0.4% or more of the patients with intact tympanic membranes. Adverse Reactions Incidence (N = 537) Ear pruritus 1.5% Ear debris 0.6% Superimposed ear infection 0.6% Ear congestion 0.4% Ear pain 0.4% Erythema 0.4% The following adverse reactions were each reported in a single patient: ear discomfort; decreased hearing; and ear disorder (tingling). 6.2 Post-marketing Experience The following adverse reactions have been identified during post approval use of ciprofloxacin and dexamethasone, otic suspension. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reactions include auricular swelling, headache, hypersensitivity, otorrhea, skin exfoliation, rash erythematous, and vomiting.

12.3 Pharmacokinetics Following a single bilateral 4-drop (total dose = 0.28 mL, 0.84 mg ciprofloxacin, 0.28 mg dexamethasone) topical otic dose of ciprofloxacin and dexamethasone, otic suspension to pediatric patients after tymoanostomy tube insertion, measurable plasma concentrations of ciprofloxacin and dexamethasone were observed at 6 hours following administration in 2 of 9 patients and 5 of 9 patients, respectively. Mean ± SD peak plasma concentrations of ciprofloxacin were 1.39 ± 0.880 ng/mL (n = 9). Peak plasma concentrations ranged from 0.543 ng/mL to 3.45 ng/mL and were on average approximately 0.1% of peak plasma concentrations achieved with an oral dose of 250 mg. Peak plasma concentrations of ciprofloxacin were observed within 15 minutes to 2 hours post dose application. Mean ± SD peak plasma concentrations of dexamethasone were 1.14 ± 1.54 ng/mL (n = 9). Peak plasma concentrations ranged from 0.135 ng/mL to 5.10 ng/mL and were on average approximately 14% of peak concentrations reported in the literature following an oral 0.5 mg tablet dose. Peak plasma concentrations of dexamethasone were observed within 15 minutes to 2 hours post dose application. Dexamethasone has been added to aid in the resolution of the inflammatory response accompanying bacterial infection (such as otorrhea in pediatric patients with AOMT).
