Summary

This randomized, three-sequence, three-period, phase 1 study is designed to assess the bioavailability and pharmacokinetics (PK) of sublingually administered atropine sulfate ophthalmic solution 1% USP (at 0.5 mg and 1.0 mg; test) compared to atropine sulfate injection administered IV (1.0 mg; reference).

Conditions

  • Toxic Effect of Organophosphate and Carbamate Insecticides

Interventions

DRUG

Atropine Sulfate Ophthalmic Solution

Atropine sulfate ophthalmic solution, USP 1% is a sterile topical anti-muscarinic indicated for cyclopegia, mydriasis, and penalization of the healthy eye in the treatment of amblyopia. Each mL of Atropine Sulfate Ophthalmic Solution USP, 1% contains active ingredient: atropine sulfate 10 mg equivalent to 8.3 mg of atropine. Inactive ingredients include benzalkonium chloride 0.1 mg (0.01%), dibasic sodium phosphate, edetate disodium, hypromellose (2910), monobasic sodium phosphate, hydrochloric acid and/or sodium hydroxide may be added to adjust pH (3.5 to 6.0), and water for injection, USP.

DRUG

Atropine Sulphate Injection

Atropine sulfate injection, USP, 8mg/20mL (0.4 mg per mL) is a sterile, nonpyrogenic, isotonic, clear solution of atropine sulfate in water for injection with sodium chloride sufficient to render the solution isotonic. Each mL contains atropine sulfate, 0.4 mg; benzyl alcohol, 9 mg; sodium chloride 9 mg; and may contain sulfuric acid for pH adjustment, pH 3.5 (3.0 to 3.8).
