WARNINGS
Included as part of the PRECAUTIONS section.
PRECAUTIONS
Delayed Healing
Topical nonsteroidal anti-inflammatory drugs (NSAIDs) may
slow or delay healing. Topical corticosteroids are also known to slow or delay
healing. Concomitant use of topical NSAIDs and topical steroids may increase
the potential for healing problems.
Cross-Sensitivity Or Hypersensitivity
There is the potential for cross-sensitivity to
acetylsalicylic acid, phenylacetic acid derivatives, and other NSAIDs. There
have been reports of bronchospasm or exacerbation of asthma associated with the
use of ketorolac tromethamine ophthalmic solution in patients who either have a
known hypersensitivity to aspirin/non-steroidal anti-inflammatory drugs, or a
past medical history of asthma. Therefore, caution should be used when treating
individuals who have previously exhibited sensitivities to these drugs.
Increased Bleeding Time
With some NSAIDs, there exists the potential for
increased bleeding time due to interference with thrombocyte aggregation. There
have been reports that ocularly applied nonsteroidal anti-inflammatory drugs
may cause increased bleeding of ocular tissues (including hyphemas) in
conjunction with ocular surgery.
It is recommended that ACUVAIL® ophthalmic
solution be used with caution in patients with known bleeding tendencies or who
are receiving other medications, which may prolong bleeding time.
Corneal Effects
Use of topical NSAIDs may result in keratitis. In some
susceptible patients, continued use of topical NSAIDs may result in epithelial
breakdown, corneal thinning, corneal erosion, corneal ulceration, or corneal
perforation. These events may be sight threatening. Patients with evidence of
corneal epithelial breakdown should immediately discontinue use of topical
NSAIDs and should be closely monitored for corneal health.
Postmarketing experience with topical NSAIDs suggests
that patients with complicated ocular surgeries, corneal denervation, corneal
epithelial defects, diabetes mellitus, ocular surface diseases (e.g., dry eye
syndrome), rheumatoid arthritis, or repeat ocular surgeries within a short
period of time may be at increased risk for corneal adverse events which may
become sight threatening. Topical NSAIDs should be used with caution in these
patients.
Postmarketing experience with topical NSAIDs also
suggests that use more than 1 day prior to surgery or use beyond 14 days
post-surgery may increase patient risk for the occurrence and severity of
corneal adverse events.
Contact Lens
Wear ACUVAIL® should not be administered
while wearing contact lenses.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Ketorolac tromethamine was not carcinogenic in either
rats given up to 5 mg/kg/day orally for 24 months or in mice given 2 mg/kg/day
orally for 18 months. These doses are approximately 900 times and 300 times
higher respectively than the typical human topical ophthalmic daily dose given
as twice daily to an affected eye on a mg/kg basis.
Ketorolac tromethamine was not mutagenic in vitro in the
Ames assay or in forward mutation assays. Similarly, it did not result in an in
vitro increase in unscheduled DNA synthesis or an in vivo increase in
chromosome breakage in mice. However, ketorolac tromethamine did result in an
increased incidence in chromosomal aberrations in Chinese hamster ovary cells.
Ketorolac tromethamine did not impair fertility when
administered orally to male and female rats at doses up to 9 mg/kg/day and 16
mg/kg/day, respectively. These doses are respectively 1500 and 2700 times
higher than the typical human topical ophthalmic daily dose.
Use In Specific Populations
Pregnancy
Teratogenic Effects
Pregnancy Category C: Ketorolac tromethamine,
administered during organogenesis, was not teratogenic in rabbits and rats at
oral doses of 3.6 mg/kg/day and 10 mg/kg/day, respectively. These doses are
approximately 600 times and 1700 times higher respectively than the typical
human topical ophthalmic daily dose of 0.35 mg (4.5 mg/mL x 0.04 mL/drop, twice
daily) to an affected eye on a mg/kg basis. Additionally, when administered to
rats after Day 17 of gestation at oral doses up to 1.5 mg/kg/day (approximately
300 times the typical human topical ophthalmic daily dose), ketorolac
tromethamine resulted in dystocia and increased pup mortality. There are no
adequate and well-controlled studies in pregnant women. ACUVAIL® solution
should be used during pregnancy only if the potential benefit justifies the
potential risk to the fetus.
Nonteratogenic Effects
Because of the known effects of prostaglandin-inhibiting
drugs on the fetal cardiovascular system (closure of the ductus arteriosus),
the use of ACUVAIL® solution during late pregnancy should be
avoided.
Nursing Mothers
Because many drugs are excreted in human milk, caution
should be exercised when ACUVAIL® is administered to a
nursing woman.
Pediatric Use
Safety and effectiveness in pediatric patients have not
been established.
Geriatric Use
No overall clinical differences in safety or effectiveness
have been observed between elderly and other adult patients.
