Lidocaine 2% with Epinephrine 2% 1:100,000 for Injection 50 mL Multiple Dose, 25/Pack (Rx)

Lidocaine 2% with Epinephrine 2% 1:100,000 is an injectable local anesthetic used to provide pain relief and reduce bleeding during surgical, dental, or other medical procedures. Lidocaine, an anesthetic agent, blocks nerve signals in the body, while epinephrine, a vasoconstrictor, decreases blood flow to the area, prolonging the anesthetic effect and minimizing bleeding. This combination is commonly utilized in various clinical settings to enhance the effectiveness and duration of anesthesia.

Mechanism of Action

Lidocaine: Works by blocking sodium channels, which inhibits the propagation of nerve impulses. This blockage results in a local anesthetic effect by temporarily numbing the area.
Epinephrine: Acts as a vasoconstrictor by stimulating alpha-adrenergic receptors, leading to decreased blood flow to the targeted area. This prolongs the effect of lidocaine and reduces bleeding.
