  • The most frequent ocular adverse reactions, occurring in less than 4% of eyes treated with alcaftadine, 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 alcaftadine, 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 alcaftadine 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, hypersensitivity, and somnolence.

Pharmacodynamics

There is limited information regarding Alcaftadine Pharmacodynamics in the drug label.

Pharmacokinetics

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.
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.
  • In vitro studies showed that neither alcaftadine nor the carboxylic acid metabolite substantially inhibited reactions catalyzed by major CYP450 enzymes.

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)

Clinical Studies

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).

How Supplied

  • Alcaftadine ophthalmic solution) 0.25% is supplied in an opaque, white low-density polyethylene bottle with a white polypropylene cap.

Patient Counseling Information

Potential for Eye Injury and Sterility of Dropper Tip

Concomitant Use with other Ophthalmic Products Contact Lenses
  • If more than one topical ophthalmic drug is being used, the drugs should be administered at least five minutes apart.
  • Patients should be advised not to wear a contact lens if their eye is red. Patients should be advised that LASTACAFT® should not be used to treat contact lens-related irritation. Patients should also be advised to 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®.
Topical Ophthalmic Use Only
  • For topical ophthalmic administration only.
