Availability & generic status
We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.
Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.
🛈 What do these terms mean?
- Patent
- Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
- Substance patent
- Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
- Formulation (product) patent
- Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
- Method-of-use patent
- A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
- Skinny label
- A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
- Exclusivity
- FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
- Paragraph IV
- A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
- RLD / RS
- Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
- TE / AB rating
- FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
- LOE (loss of exclusivity)
- The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.
Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no available human data for the use of besifloxacin ophthalmic suspension during pregnancy to inform any drug-associated risks; however, systemic exposure to besifloxacin from ocular administration is low [see Clinical Pharmacology (12.3 )] . Oral administration of besifloxacin to pregnant rats during organogenesis or during the prenatal and postnatal period did not produce adverse embryofetal or offspring effects at clinically relevant systemic exposures [see Data ] . Data Animal Data In an embryofetal development study in rats, the administration of besifloxacin at oral doses up to 1,000 mg/kg/day during organogenesis was not associated with visceral or skeletal malformations in rat fetuses, although this dose was associated with maternal toxicity (reduced body weight gain and food consumption) and maternal mortality.
Increased post-implantation loss, decreased fetal body weights, and decreased fetal ossification were also observed. At this dose, the mean C max in the rat dams was approximately 20 mcg/mL, approximately 46,500 times the mean plasma concentrations measured in humans at the recommended human ophthalmic dose (RHOD). The No Observed Adverse Effect Level (NOAEL) for this embryofetal development study was 100 mg/kg/day (C max , 5 mcg/mL, approximately 11,600 times the mean plasma concentrations measured in humans at the RHOD).
In a prenatal and postnatal development study in rats, the NOAELs for both fetal/neonate and maternal toxicity were 100 mg/kg/day. At 1,000 mg/kg/day, pups weighed significantly less than controls and had a reduced neonatal survival rate. Attainment of developmental landmarks and sexual maturation was delayed, although surviving pups from this dose group that were reared to maturity did not demonstrate deficits in behavior, including activity, learning and memory, and their reproductive capacity appeared normal.
8.2Lactation Risk Summary There are no data on the presence of besifloxacin ophthalmic suspension in human milk, the effects on the breastfed infant, or the effects on milk production. However, systemic exposure to besifloxacin following topical ocular administration is low [see Clinical Pharmacology ( 12.3 )] , and it is not known whether measurable levels of besifloxacin would be present in maternal milk following topical ocular administration. The developmental and health benefits of breastfeeding should be considered, along with the mother’s clinical need for besifloxacin ophthalmic suspension, and any potential adverse effects on the breastfed infant from besifloxacin ophthalmic suspension.
8.4Pediatric Use The safety and effectiveness of besifloxacin ophthalmic suspension in infants below one year of age have not been established. The efficacy of besifloxacin ophthalmic suspension in treating bacterial conjunctivitis in pediatric patients one year or older has been demonstrated in controlled clinical trials [see Clinical Studies ( 14 )]. There is no evidence that the ophthalmic administration of quinolones has any effect on weight-bearing joints, even though systemic administration of some quinolones has been shown to cause arthropathy in immature animals.
8.5Geriatric Use No overall differences in safety and effectiveness have been observed between elderly and younger patients.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Besifloxacin is a fluoroquinolone antibacterial [see Microbiology ( 12.4 )] .
12.3Pharmacokinetics Plasma concentrations of besifloxacin were measured in adult patients with suspected bacterial conjunctivitis who received besifloxacin ophthalmic suspension bilaterally three times a day (16 doses total). Following the first and last dose, the maximum plasma besifloxacin concentration in each patient was less than 1.3 ng/mL. The mean besifloxacin C max was 0.37 ng/mL on Day 1 and 0.43 ng/mL on Day 6.
The average elimination half-life of besifloxacin in plasma following multiple dosing was estimated to be 7 hours.
12.4Microbiology Besifloxacin is an 8-chloro fluoroquinolone with an N-1 cyclopropyl group. The compound has activity against Gram-positive and Gram-negative bacteria due to the inhibition of both bacterial DNA gyrase and topoisomerase IV. DNA gyrase is an essential enzyme required for replication, transcription and repair of bacterial DNA.
Topoisomerase IV is an essential enzyme required for partitioning of the chromosomal DNA during bacterial cell division. Besifloxacin is bactericidal with minimum bactericidal concentrations (MBCs) generally within one dilution of the minimum inhibitory concentrations (MICs). The mechanism of action of fluoroquinolones, including besifloxacin, is different from that of aminoglycoside, macrolide, and β-lactam antibiotics.
Therefore, besifloxacin may be active against pathogens that are resistant to these antibiotics and these antibiotics may be active against pathogens that are resistant to besifloxacin. In vitro studies demonstrated cross-resistance between besifloxacin and some fluoroquinolones. In vitro resistance to besifloxacin develops via multiple-step mutations and occurs at a general frequency of <3.3 x 10 -10 for Staphylococcus aureus and <7 x 10 -10 for Streptococcus pneumoniae .
Besifloxacin has been shown to be active against most isolates of the following bacteria both in vitro and in conjunctival infections treated in clinical trials [see Indications and Usage ( 1 )] : Aerococcus viridans* CDC coryneform group G Corynebacterium pseudodiphtheriticum* Corynebacterium striatum* Haemophilus influenzae Moraxella catarrhalis* Moraxella lacunata* Pseudomonas aeruginosa* Staphylococcus aureus Staphylococcus epidermidis Staphylococcus hominis* Staphylococcus lugdunensis* Staphylococcus warneri* Streptococcus mitis group Streptococcus oralis Streptococcus pneumoniae Streptococcus salivarius* *Efficacy for this organism was studied in fewer than 10 infections.

🔬 Clinical Studies ▾
14 CLINICAL STUDIES In a randomized, double-masked, vehicle-controlled, multicenter clinical trial, in which patients 1-98 years of age were dosed 3 times a day for 5 days, besifloxacin ophthalmic suspension was superior to its vehicle in patients with bacterial conjunctivitis. Clinical resolution was achieved in 45% (90/198) for the besifloxacin ophthalmic suspension-treated group versus 33% (63/191) for the vehicle-treated group (difference 12%, 95% CI 3% - 22%). Microbiological outcomes demonstrated a statistically significant eradication rate for causative pathogens of 91% (181/198) for the besifloxacin ophthalmic suspension-treated group versus 60% (114/191) for the vehicle-treated group (difference 31%, 95% CI 23% - 40%).
Microbiologic eradication does not always correlate with clinical outcome in anti-infective trials.
🧪 Nonclinical Toxicology ▾
13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term studies in animals to determine the carcinogenic potential of besifloxacin have not been performed. No in vitro mutagenic activity of besifloxacin was observed in an Ames test (up to 3.33 mcg/plate) on bacterial tester strains Salmonella typhimurium TA98, TA100, TA1535, TA1537 and Escherichia coli WP2uvrA. However, it was mutagenic in S. typhimurium strain TA102 and E. coli strain WP2 (pKM101).
Positive responses in these strains have been observed with other quinolones and are likely related to topoisomerase inhibition. Besifloxacin induced chromosomal aberrations in CHO cells in vitro and it was positive in an in vivo mouse micronucleus assay at oral doses ≥1,500 mg/kg. Besifloxacin did not induce unscheduled DNA synthesis in hepatocytes cultured from rats given the test compound up to 2,000 mg/kg by the oral route.
In a fertility and early embryonic development study in rats, besifloxacin did not impair the fertility of male or female rats at oral doses of up to 500 mg/kg/day. This dose is approximately 26,500 times higher than the mean plasma concentration measured in humans at the recommended human ophthalmic dose.
