Butacaine

Butacaine is an ester-type local anesthetic used for surface anesthesia by blocking nerve conduction and providing temporary numbness.

Structure of Butacaine

• It is an amino benzoic acid derivative with a butyl ester group, providing effective local anesthetic properties.
• Chemical Formula: C₁₀H₂₁N₃O₂

Mode of Action

• Sodium Channel Blockade: Inhibits voltage-gated sodium channels, preventing nerve impulse propagation.
• Membrane Stabilization: Reduces nerve excitability by altering membrane potential.

Uses

• Local Anesthesia: Utilized in dental procedures, minor surgeries, and dermatological applications.
• Topical Preparations: Applied to skin and mucous membranes for numbing before minor interventions.
• Infiltration Anesthesia: Injected to numb specific areas during medical procedures.

Side Effects of Butacaine

• Local Irritation: May cause redness, swelling, or itching at the application site.
• Systemic Toxicity: Rare but possible with excessive use, leading to CNS and cardiovascular effects.
