Uses
Tetracaine Minims is a local anaesthetic agent used to induce local analgesia in the eyes and skin during medical procedures.
Ophthalmic tetracaine is indicated for the for procedures requiring a rapid and short- acting topical ophthalmic anesthetic.
The combination lidocaine and tetracaine patch is indicated for local dermal analgesia for superficial dermatological procedures and superficial venous access. The combination lidocaine and tetracaine cream is intended to provide topical local analgesia for superficial dermatological procedures.
Tetracaine Minims is also used to associated treatment for these conditions: Dermabrasion, Hemorrhoids, Insect Bites, Rash caused by poison ivy, Sunburn, Minor burns, Anesthetics, Local, Local Anesthesia of the Skin, Local anesthesia therapy
How Tetracaine Minims works
Tetracaine Minims is an ester-type anesthetic and produces local anesthesia by blocking the sodium ion channels involved in initiation and conduction of neuronal impulses.
Toxicity
The most common adverse effects with the combination cream are localized reactions such as: erythema (47%), skin discoloration (16%), and edema (14%). Systemic adverse events were less common, occurring at a rate of <1% and included vomiting, headache, dizziness, and fever. Similar to other amide and ester anesthetics, CNS excitation and/or depression may occur. It is not well known at which plasma concentration systemic toxicity occurs with tetracaine; however, the threshold is thought to be much lower than that of lidocaine which is 1000 ng/mL.
Food Interaction
No interactions found.Tetracaine Minims Drug Interaction
Major: procaine penicillinModerate: lorazepam, midazolamUnknown: aspirin, charcoal, epinephrine, azithromycin, diphenhydramine, glucose, ethanol, lithium, morphine, acetaminophen, valproic acid, cyanocobalamin, riboflavin, pyridoxine, ascorbic acid, cholecalciferol, ondansetron
Volume of Distribution
Tetracaine Minims is rapidly hydrolyzed in the plasma; therefore, volume of distribution could not be determined.
Elimination Route
Systemic absorption of anaesthetic from the combination cream is directly related to the duration and surface area of application. Although peak plasma concentrations for lidocaine were measured, plasma levels for tetracaine could not be determined due to low levels (<0.9 ng/mL)
Half Life
Tetracaine Minims is hydrolyzed rapidly in the plasma; therefore, half-life has not been determined.
Clearance
Tetracaine Minims is hydrolyzed rapidly in the plasma; therefore, clearance has not been determined.
