Tetracaine

Introduction

Tetracaine is a local anesthetic medication primarily used to numb specific areas of the body before medical procedures. It is commonly applied topically or used in eye drops, injections, and spinal anesthesia. Tetracaine belongs to the ester-type group of local anesthetics and provides fast and effective relief by temporarily blocking nerve signals in the area of application. It is widely used in hospitals, clinics, and diagnostic labs for short-term pain relief during minor procedures or examinations.

Uses of Tetracaine

• Used for local anesthesia during minor surgical procedures
• Applied before diagnostic eye examinations like tonometry
• Used to numb the skin or mucous membranes before insertion of instruments
• Helps relieve pain and discomfort caused by skin irritations or insect bites
• Used in spinal anesthesia for surgeries involving the lower body

How Tetracaine works

Tetracaine works by blocking sodium channels in nerve cells, preventing the initiation and conduction of nerve impulses. This leads to temporary loss of sensation in the area where it is applied, providing effective local anesthesia. Its fast onset and moderate duration make it suitable for a wide range of medical uses.
