LASTACAFT® is an H1 histamine receptor antagonist indicated for the prevention of itching associated with allergic conjunctivitis.
Instill one drop in each eye once daily. If more than 1 topical ophthalmic medicinal product is being used, each one should be administered at least 5 minutes apart.
LASTACAFT® is contraindicated in patients with hypersensitivity to any component in the product.
WARNINGS
Included as part of the PRECAUTIONS section.
PRECAUTIONS
Potential For Eye Injury And Contamination
To minimize eye injury and contamination of the dropper tip and solution, care should be taken not to touch the eyelids or surrounding areas with the dropper tip of the bottle. Keep bottle tightly closed when not in use.
Contact Lens Use
Patients should be advised not to wear a contact lens if their eye is red.
LASTACAFT® should not be used to treat contact lens-related irritation.
LASTACAFT® should not be instilled while wearing contact lenses. Remove contact lenses prior to instillation of LASTACAFT®. The preservative in LASTACAFT®, benzalkonium chloride, may be absorbed by soft contact lenses. Lenses may be reinserted after 10 minutes following administration of LASTACAFT®.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Alcaftadine was not mutagenic or genotoxic in the Ames test, the mouse lymphoma assay or the mouse micronucleus assay.
Alcaftadine was found to have no effect on fertility of male and female rats at oral doses up to 20 mg/kg/day (approximately 200 times the plasma exposure at the recommended human ocular dose).
Use In Specific Populations
Pregnancy
Pregnancy Category B. Reproduction studies performed in rats and rabbits revealed no evidence of impaired female reproduction or harm to the fetus due to alcaftadine. Oral doses in rats and rabbits of 20 and 80 mg/kg/day, respectively, produced plasma exposure levels approximately 200 and 9000 times the plasma exposure at the recommended human ocular dose. There are however, no adequate and well controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
Nursing Mothers
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when LASTACAFT® is administered to a nursing woman.
Pediatric Use
Safety and effectiveness in pediatric patients below the age of 2 years have not been established.
Geriatric Use
No overall differences in safety or effectiveness were observed between elderly and younger subjects.
SIDE EFFECTS
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Clinical Studies Experience
The most frequent ocular adverse reactions, occurring in less than 4% of eyes treated with LASTACAFT®, were eye irritation, burning and/or stinging upon instillation, eye redness and eye pruritus.
Non-ocular Adverse Reactions
The most frequent non-ocular adverse reactions, occurring in less than 3% of subjects with eyes treated with LASTACAFT®, were nasopharyngitis and headache. Some of these events were similar to the underlying disease being studied.
Postmarketing Experience
The following adverse reactions have been identified during postmarketing use of LASTACAFT® in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These reactions include eye discharge, eye swelling, erythema of eyelid, eyelid edema, lacrimation increased, vision blurred, hypersensitivity reactions including swelling of the face or allergic dermatitis, and somnolence.

Absorption
Following bilateral topical ocular administration of alcaftadine ophthalmic solution, 0.25%, the mean plasma Cmax of alcaftadine was approximately 60 pg/mL and the median Tmax occurred at 15 minutes. Plasma concentrations of alcaftadine were below the lower limit of quantification (10 pg/mL) by 3 hours after dosing. The mean Cmax of the active carboxylic acid metabolite was approximately 3 ng/mL and occurred at 1 hour after dosing. Plasma concentrations of the carboxylic acid metabolite were below the lower limit of quantification (100 pg/mL) by 12 hours after dosing. There was no indication of systemic accumulation or changes in plasma exposure of alcaftadine or the active metabolite following daily topical ocular administration.
Distribution
The protein binding of alcaftadine and the active metabolite are 39.2% and 62.7%, respectively.
Metabolism
The metabolism of alcaftadine is mediated by non-CYP450 cytosolic enzymes to the active carboxylic acid metabolite. In vitro studies showed that neither alcaftadine nor the carboxylic acid metabolite substantially inhibited reactions catalyzed by major CYP450 enzymes.
Excretion
The elimination half-life of the carboxylic acid metabolite is approximately 2 hours following topical ocular administration. Based on data following oral administration of alcaftadine, the carboxylic acid metabolite is primarily eliminated unchanged in the urine.
However, we will provide data for each active ingredient
