Used for ophthalmic procedures requiring local anesthesia, such as minor eye surgeries, corneal procedures, and diagnostic examinations. May also be used for procedures involving the ear, nose, or throat where vasoconstriction is beneficial.
Tetracaine blocks sodium channels in nerve fibers, preventing the generation and transmission of pain signals. Adrenalone acts as a vasoconstrictor, reducing blood flow to the treatment area, which helps minimize bleeding and prolongs the local anesthetic effect by decreasing systemic absorption.
For topical use only; not for injection. Use with caution in patients with cardiovascular conditions, hyperthyroidism, or diabetes due to the vasoconstrictor component. Should not be used on inflamed or infected tissues. Prolonged use may cause corneal epithelial damage. Allergic reactions to ester-type anesthetics or sulfite preservatives should be ruled out before use.
