11 Description

Tetracaine Hydrochloride Ophthalmic Solution, USP 0.5% is a sterile, clear, colorless, topical local anesthetic for ophthalmic use only containing tetracaine hydrochloride as the active pharmaceutical ingredient.

Tetracaine hydrochloride is chemically designated as benzoic acid, 4-(butylamino)-, 2-(dimethylamino) ethyl ester, monohydrochloride. Its chemical formula is C₁₅H₂₄N₂O₂ ● HCl and it is represented by the chemical structure:

chemstructure - chemstructure

Tetracaine hydrochloride is a fine, white, crystalline, odorless powder with a molecular weight of 300.83.

Active ingredient: tetracaine hydrochloride 0.5% w/v (equivalent to 0.44% w/v tetracaine)

Preservative: chlorobutanol 0.4%

Inactive ingredients: boric acid, edetate disodium dihydrate, potassium chloride, water for injection. Sodium hydroxide and/or hydrochloric acid may be added to adjust pH (3.7 – 6.0).

12.1 Mechanism Of Action

Tetracaine blocks sodium ion channels required for the initiation and conduction of neuronal impulses thereby affecting local anesthesia.

12.3 Pharmacokinetics

The systemic exposure to tetracaine following topical ocular administration of Tetracaine Hydrochloride Ophthalmic Solution, USP 0.5% has not been studied. Tetracaine hydrochloride is metabolized by plasma pseudocholinesterases and nonspecific esterases in ocular tissues.

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

Studies to assess the genotoxicity of tetracaine hydrochloride have not been reported in the published literature. Long-term animal studies have not been conducted to evaluate the carcinogenic potential of tetracaine hydrochloride. Animal studies to assess the effects of tetracaine hydrochloride on fertility have not been reported in the published literature.

14 Clinical Studies

Topical administration of Tetracaine Hydrochloride Ophthalmic Solution, USP 0.5% results in localized temporary anesthesia. The maximum effect is achieved within 10–20 seconds after instillation, with efficacy lasting 10–20 minutes.
