Symptoms similar to cold syndrome and pharyngitis were reported at an incidence of approximately 10%.
The following adverse experiences have been reported in 5% or less of patients:
Ocular: blurred vision, burning or stinging, conjunctivitis, dry eye, foreign body sensation, hyperemia, hypersensitivity, keratitis, lid edema, pain and ocular pruritus.
Non-ocular: asthenia, back pain, flu syndrome, headache, increased cough, infection, nausea, rhinitis, sinusitis and taste perversion.
Some of these events were similar to the underlying disease being studied.

Alerchek was found not to be teratogenic in rats and rabbits. However, rats treated at 600 mg/kg/day, or 150,000 times the MROHD and rabbits treated at 400 mg/kg/day, or approximately 100,000 times the MROHD, during organogenesis showed a decrease in live fetuses. In addition, rats treated with 600 mg/kg/day of Alerchek during organogenesis showed a decrease in fetal weight. Further, rats treated with 600 mg/kg/day of Alerchek during late gestation through the lactation period showed a decrease in neonatal survival and body weight. There are, however, no adequate and well-controlled studies in pregnant women. Because animal studies are not always predictive of human responses, this drug should be used in pregnant women only if the potential benefit to the mother justifies the potential risk to the embryo or fetus.
Alerchek has been identified in the milk of nursing rats following oral administration. It is not known whether topical ocular administration could result in sufficient systemic absorption to produce detectable quantities in the human breast milk. Nevertheless, caution should be exercised when Alerchek hydrochloride ophthalmic solution, 0.2% is administered to a nursing mother.
Safety and effectiveness in pediatric patients below the age of 2 years have not been established.
No overall differences in safety and effectiveness have been observed between elderly and younger patients.
Alerchek hydrochloride ophthalmic solution, 0.2% is a sterile ophthalmic solution containing Alerchek for topical administration to the eyes. Alerchek hydrochloride is a white, crystalline, water-soluble powder with a molecular weight of 373.88 and a molecular formula of C21H23NO3-HCl.
The chemical structure is presented below:
Chemical Name: 11-[(Z)-3-(Dimethylamino)propylidene]-6-11-dihydrodibenz[b,e]oxepin-2-acetic acid, hydrochloride.
Each mL of Alerchek hydrochloride ophthalmic solution, 0.2% contains: Active: 2.22 mg Alerchek hydrochloride equivalent to 2 mg Alerchek. Inactives: povidone; dibasic sodium phosphate; sodium chloride; edetate disodium; benzalkonium chloride 0.01% (preservative); hydrochloric acid/sodium hydroxide (adjust pH); and purified water for injection.
It has a pH of approximately 7 and an osmolality of approximately 300 mOsm/kg.
Alerchek is a mast cell stabilizer and a histamine H1 antagonist. Decreased chemotaxis and inhibition of eosinophil activation has also been demonstrated.
Systemic bioavailability data upon topical ocular administration of Alerchek hydrochloride ophthalmic solution are not available. Following topical ocular administration of Alerchek 0.15% ophthalmic solution in man, Alerchek was shown to have a low systemic exposure. Two studies in normal volunteers (totaling 24 subjects) dosed bilaterally with Alerchek 0.15% ophthalmic solution once every 12 hours for 2 weeks demonstrated plasma concentrations to be generally below the quantitation limit of the assay (˂0.5 ng/mL). Samples in which Alerchek was quantifiable were typically found within 2 hours of dosing and ranged from 0.5 to 1.3 ng/mL. The elimination half-life in plasma following oral dosing was 8 to 12 hours, and elimination was predominantly through renal excretion. Approximately 60 to 70% of the dose was recovered in the urine as parent drug. Two metabolites, the mono-desmethyl and the N-oxide, were detected at low concentrations in the urine.
Alerchek administered orally was not carcinogenic in mice and rats in doses up to 500 mg/kg/day and 200 mg/kg/day, respectively. Based on a 40 µL drop size and a 50 kg person, these doses were approximately 150,000 and 50,000 times higher than the maximum recommended ocular human dose (MROHD). No mutagenic potential was observed when Alerchek was tested in an in vitro bacterial reverse mutation (Ames) test, an in vitro mammalian chromosome aberration assay or an in vivo mouse micronucleus test. Alerchek administered to male and female rats at oral doses of approximately 100,000 times MROHD level resulted in a slight decrease in the fertility index and reduced implantation rate; no effects on reproductive function were observed at doses of approximately 15,000 times the MROHD level.
Results from clinical studies of up to 12 weeks duration demonstrate that Alerchek hydrochloride ophthalmic solution, 0.2% when dosed once a day is effective in the treatment of ocular itching associated with allergic conjunctivitis.
