1% LIDOCAINE HCI, 2% LIDOCAINE HCI

What is this medication?

Lidocaine Hydrochloride 1% and 2% are local anesthetic medications used to provide temporary numbness to a specific area of the body. They belong to a class of drugs known as amino amide-type local anesthetics. These medications work by blocking the nerve signals in the body that send pain messages to the brain. When injected or applied by a healthcare professional, the drug prevents the movement of sodium ions into the nerve cells, which stops the conduction of pain impulses. This effect allows patients to undergo various medical interventions with minimal discomfort.

Healthcare providers commonly use these specific concentrations for a variety of minor surgical procedures, such as suturing wounds, performing biopsies, or administering dental treatments. The 1% solution contains ten milligrams of lidocaine per milliliter, while the 2% solution is more concentrated, containing twenty milligrams per milliliter. The choice between the two concentrations often depends on the depth of anesthesia required and the expected duration of the procedure. Beyond numbing, certain formulations of lidocaine are also used in emergency settings to treat specific types of irregular heartbeats, though their most common role is as a localized pain blocking agent.
