Pharmacology/ Pharmacokinetics:
1 Mechanism of Action
Alcaftadine is an H1 histamine receptor antagonist and inhibitor of the release
of histamine from mast cells. Decreased chemotaxis and inhibition of eosinophil
activation has also been demonstrated.
2. 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.
Pregnancy and lactation:
USE IN SPECIFIC POPULATIONS
1 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.
2. 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.
3. Pediatric Use
Safety and effectiveness in pediatric patients below the age of 2 years
have not been established.
4. Geriatric Use
No overall differences in safety or effectiveness were observed between
elderly and younger subjects.
